  The U.S.  Environmental  Protection Agency (EPA) is charged by Congress with
protecting  the  Nation's land,  air, and water  resources.  As the enforcer of
national environmental  laws, the EPA strives to balance human activities and
the  ability of natural  systems to support  and  nurture  life.  A key part of  the
EPA's effort  is  its  research into our environmental problems to find new and
innovative  solutions.

  The Risk  Reduction  Engineering Laboratory (RREL)  is responsible for
planning,  implementing,   and managing research, development, and demonstration
programs to provide  an  authoritative,  defensible engineering basis in support
of the policies, programs,  and regulations of the EPA with respect to drinking
water,  wastewater,  pesticides,   toxic substances, solid and hazardous wastes,
and  Super fund-related activities.   This  publication is one of the products  of
that research and provides  a vital communication link between the researcher
and the user  community.

  Now in its  eighth year,  the  Superfund Innovative Technology Evaluation
(SITE) Program  is part  of EPA's research into cleanup methods for hazardous
waste sites around the  Nation.   Through  cooperative agreements with
developers, alternative or  innovative technologies  are refined at the
bench-and-pilot  scale level and  then  demonstrated  at actual sites.  EPA
collects and  evaluates  extensive performance data on each technology to use in
remediation decision-making for hazardous  waste sites.

  This report documents the results of 11 months laboratory-scale testing of
an engineered biofilter using  an  active synthetic medium.   Effective and
efficient removal for a low level organic  contaminant,  toluene,  from air was
demonstrated.   A pilot-scale stand-alone unit  with  a compressor,  biomass
removal  capabilities, and an  inorganic nutrient supply/recycle system, capable
of handling 4 CFM of  flow,  was  designed and constructed.   The unit will be
used for field pilot  testing under an unattended mode of operation.

                                    ABSTRACT
  An engineered biofliter was  developed to digest hazardous organic emissions
from soil, water,  and air decontamination processes. A bench  scale under the
SITE Emerging Technology Program was tested for  > 11 months for the removal of
low level toluene in air.

  The bioscrubber  contains  a selected activated  carbon medium to support
microbial growth.   The bioscrubber was designed for large volume air streams
containing trace volatile organics.   Almost complete removal of hazardous
organics was demonstrated.   Compared with other biofilters using compost or
other naturally occurred media,  the use of activated carbon in the bioscrubber
enhanced the degradation efficiency substantially for the test performed.

  The bioscrubber efficiency results from the  adsorption  affinity and ideal
environment for biogrowth offered  by activated  carbon.   The adsorption
affinity provides a sink for contaminants to enhance the  biodegradation
efficiency.   It  also  cushions  the feed fluctuations to achieve a consistent
and high  level removal  efficiency.   In a bench scale-unit,  >95% removal was
demonstrated for an air stream containing <5 to 40  ppm of toluene.

  A pilot-scale test unit, capable of handling  4  CFM of flow,  was designed and
constructed.   It  is a stand-alone unit with a compressor, backwashing
capabilities,  and  an  inorganic nutrient supply/recycle system.   The unit was
intended to be used in a field test under an unattended  mode of operation.

816813010 by Aluminum Company  of America,  under the partial sponsorship of the
Environmental  Protection Agency.   This report covers a period from July 1990
to February 28, 1993 and work  was completed as of  February 28,  1993.

     EXECUTIVE SUMMARY

     Biofiltration has been  accepted  recently  for trace contaminant removal
from air.   The existing  technology  uses  naturally occurring materials, such as
compost,  bark, peat,  etc.  Under  the  SITE Emerging Technology Program, an
engineered biofilter has been developed  using  an  active synthetic medium,
activated carbon, which  offers more effective,  reliable and efficient
operation.   Through advanced engineering design,  this filter incorporates the
features of bio-mass  removal, nutrient  supplement,  and moisture addition.
This advanced filter  was developed based upon  > 11 months  of operating
experience  using a bench-scale unit.  The unit consistently demonstrated > 95%
of removal efficiency for an air  stream  contaminated with  -10 ppm of toluene
with an empty bed contact time of ~1 second.   Its degradation rate was 40-80
times higher than the rate of existing systems using naturally occurring
materials  under the performed condition.   This enhanced degradation efficiency
is probably due to the adsorption offered by the  activated carbon to enhance
the substrate concentration.

  In addition  to the efficient degradation, the biofilter with  activated
carbon media provides an effective  sink  to cushion the feed fluctuation.   This
was evidenced by the consistent removal  of the contaminant  during the > 11
months of operation with a feed fluctuated  from  < 5  to 40  ppm. Pressure drop
of 0-20" of water was observed during the 11 months  of operation.   The
pressure drop was primarily  attributed to the  restriction  and flow
distribution experienced with a small-scale bench-top  unit.  The  actual
pressure drop for a bio-filter  is anticipated  to  be  minimal due to the use  of
a shallow bed.

  The biomass generated from the  filter  is  believed  to be similar to the
sludge generated  from the biological  water and  wastewater treatment. If
non-biodegradable contaminants  are  present in the feed, they may be trapped in
the bio-mass  due  to  the  exposure of the  biomass  to  the feed.  Further study
may be necessary to determine the extent of the accumulation and, if
necessary, an appropriate  disposal  of the bio-mass.

  The proposed technology will have a wide spectrum  of applications to clean
up superfund sites.    Potential  areas  include:  (1) organic  emission control  for
groundwater decontamination  using air strippers,  (2)  emission control for
biological treatment of  ground and  surface water,  and (3)  emission control  for
soil decontamination.   These primary  treatment processes currently under
development or practice have not  been designed to prevent VOC emission from
discharging  into the atmosphere.  However,  the requirement of treating these
airborne pollutants may  cause these treatment  processes to  become expensive or
prohibitive  economically.  The proposed  technology is an ideal post-treatment
for these processes due  to  its  effectiveness in handling trace organic
volatiles  economically and effectively.

  The bioscrubber developed here using activated carbon as  a medium provides
several operational advantages over conventional  activated carbon adsorbers
for the above applications.   The  bio-regeneration keeps the maximum adsorption
capacity available constantly; thus, the mass  transfer zone remains stationary
and relatively short.   No regeneration of the  carbon is required and the bed
length required is greatly reduced.   These features  translate into a reduced
capital  and operational  cost.  The  bioscrubber's  advantages would be fully

-------
utilized when off-gas  contains  weakly adsorbed contaminants, such as methylene
chloride, or adsorbates competing with moisture in the stream.    Finally  the
chromatographic effect  (or  premature  desorption)  commonly experienced in an
adsorber would not exist because the  maximum capacity is available constantly.
The bioscrubber is anticipated  to replace some existing applications currently
using activated carbon.

  A pilot unit has been designed and  constructed  and  will  be field-tested at
selected Superfund sites in the near  future.   The unit includes a feed
delivery system with a compressor,  an inorganic nutrient  storage and delivery
system, and the bio-mass removal device.   The unit is intended to be operated
under an  "unattended" mode.
II.  INTRODUCTION

     Biofiltration,  in  its most general  sense,  is the removal and
decomposition of contaminants from gases into  nonhazardous substances through
the use of  micro-organisms.   Bio-filters are believed to be the most
economical way to treat the  low level  contaminants (up to several thousand
ppm) in gas streams.

  For efficient operation, the filter  media  must  meet several requirements:

      Provide optimum environmental  conditions  for the resident microbes
      Consist of uniform pore size and particle structure (for low bed
  pressure drop,  minimizing gas channeling, high  reactive surfaces)
      Have minimal  bed  compaction  (minimize  maintenance,  media replacement)

  Composition of an existing commercially available biofilter, compost and
other naturally occurring  media, generally satisfies the first requirement by
providing sufficient nutrients for the micro-organisms (typically bacteria),
except for  particularly  refractory contaminants (i.e., chlorinated
compounds)    The problem with composting, however,  is the huge space
requirement compounded  by  continual  loss of effective surface area during
biomass build up (slothing).

  An activated carbon-based  biofiltration  module,  a bio-scrubber, has been
developed to  improve the  existing bio-filtration  systems.  These synthetically
produced filters address the current deficiencies of composting and other
naturally occurring media-based biofilters.   Its  advantages are:

      Low pressure  drops
      Minimal pressure  drop  loss due to  slothing
      Much  smaller  bed  requirements  (allows  the use of compact filters only)
      Allows  removal of biomass if necessary
      High  water retention in the  microporosity (long shelf life while not in
  use;  during start  up/shut  down,   minimal requirement for additional water
  addition)

  In addition, activated carbon media  beds provide one more key separation
mechanism for biofilters,  adsorption of  gases onto the carbon.   This  provides
the following advantages:

-------
       Increased surface concentration of contaminants
       Removal of hydrophobic gases that would  not typically be absorbed into
  the aqueous phase
      Allow  the biofilter to be efficient at lower concentrations of
  contaminants

  The above  attributes  also  could result  in enhanced biodegradation of
 substances that would not typically be efficiently degraded in a biofilter
 providing additional  applications for the  technology.

 This study focused on the development of  an  advanced  biofilter using  selected
 activated carbon as media.   The engineering consideration required  included
 (1)  environment for biogrowth,  (2) nutrient supplement device, and  (3) biomass
 removal  mechanism   The filter thus developed demonstrated an efficient and
 effective removal  of  toluene removal  from air  for > 11 months  of operation.


Ill  CONCLUSIONS  AND  RECOMMENDATIONS

 A bench-scale bio-scrubber was operated for  >  11 months,  successfully
 demonstrating an effective and efficient removal  for a low  level inorganic
 contaminant,  i.e.,  -10 ppm of toluene in  air.  The unit is packed with a
 selected granular activated carbon,   instead  of compost-type media used  in the
 existing biofiltration technologies.   This reusable active medium allows the
 removal  of the  biomass,  when necessary,  to prevent the compaction of the
 medium as  experienced using existing  technology.   In  addition,  the  unit
 demonstrated 40-80 times higher biodegradation rate than the existing
 technology's under the testing condition.   The  pressure drop experienced
 during the  11 month period is  minimal,  i.e.,  0  to 20 inches of water for most
 of the time.   The occasional removal  of the biomass helps to control the
 pressure drop at this desirable  level. The unit offers a desirable
 environment  for biogrowth by maintaining a humid state and supplementing
 inorganic  nutrients.   A pilot unit has been designed and constructed with
 these  features,  and field-testing at  selected superfund sites is recommended.


IV.  DISCUSSION

 A.    BACKGROUND

After the award of this project by US EPA (CR-816813),  several  biofilter
 systems  developed in Europe were introduced  into the U.S. Although these
 biofilters  are  different from the bioscrubber developed here, they share the
 similarity  in terms of application and basic  principle.   In  addition, a review
 paper9 was published summarizing  the  state-of-the-art  biofiltration
 technology.   The literature review here highlights the key elements involving
 the existing commercially available technology outlined in Reference 9 as
 baseline information  for bench-marking purposes.

 1.   General  Overview

 Biofiltration is now  a well-established air pollution  control  technology in
 several  European countries.   As many as 500 biofilters are currently in use  in
 Germany  and  the Netherlands.   Some development and installations have been

-------
 made  in  the United States since ~1960's,  although to a much  lesser extent1'8.
 Control efficiencies of >90% have been achieved  from  many common air
 pollutants.   Due to lower operating  cost,  bio-filtration  if applied to
 appropriate systems can provide significant  economic  advantages over other air
 pollution control technologies.   It  is suitable for  off-gases  containing
 readily biodegradable pollutants in  low concentrations, typically less than
 several thousand ppm as methane.    Environmental  benefits  include low energy
 requirements for operation and a complete  degradation of  the  pollutants.

 Biofiltration is a technology utilizing a  fixed-biological  film supported on
 the solid phase to remove air contaminants from  off-gas streams through
 aerobic degradation.   End products from the  complete  biodegradation of air
 contaminants are C02,  water,  and  microbial  biomass.    The  oxidation  of reduced
 sulfur and chlorina ted  organic compounds also generates inorganic acids,  which
 could change the pH  of the system and possibly are toxic to the bacteria.

2 .   Configuration

 To date, most  biofilters  have been built  as open single-bed  systems. Open,
 multiple  story  systems  are also built if space constraints  exist.   Some
 European firms  have developed enclosed systems usually with stacked beds.
 Media used  include compost,  mineral  soil,  peats and  others.  Microscopically,
 a biofilter can be perceived  as a  biofilm  established around  the media; a
 concentration profile exists  from  the bulk gas stream through the biofilm and
 then to the solid surface.  A first  order  degradation kinetics has  been
 suggested although the actual degradation  kinetics  is probably far more
 complicated.   Many of the existing biofilters  are single  systems installed on
 livestock and food  processing applications.  Filter areas typically range from
 100 to 22,000  ft (10 to 2,000 M  )  with off-gas  flow rates between  600  to
 90,000 CFM  (1,000 to  150,000 M3/hr).

3 .    Key System  and Operating  Variables

   • Acclimation

     For common, easily biodegradable organic compounds, acclimation typically
   requires  about 10 days.   If compounds,  that are less biodegradable and for
   which suitable microorganisms are  less likely  to  be initially present in the
   filter material,  are to be  treated, inoculation with an appropriate culture
   can reduce the acclimation  period, and such  inoculation is  practiced by
   several firms.

   • Temperature and Degradation  Rate

    For optimum  results,  it is recommended that  the off-gas temperature be
   maintained between 20 to  40'C  (68  to 105"F). A decline  in removal
   efficiency could occur at lower  temperatures,  particularly  <10'C.
   Degradation rates of common air pollutants typically range  from 10 to 100
   g/M3/hr.   The  degradation rate for  toluene  was  reported  to be 20 to 30
   g/M3/hr for the concentration  > 200 ppm. A nearly linear relationship
   between the degradation  rate vs.  concentration was  reported  for the
   concentration < 200  ppm.

-------
   •  Flow Rates

    Filter  loads  of up to 300 M3/hr  of off-gas per M2  of filter (16 scfm ft2)
   are  usually feasible without resulting in excessively high back pressures.
   Surface  loads  as high as 500 M3/m2/hr have been treated with good removal
   efficiency.   The pressure drop at  300M3/hr/M2 is about 6" and then
   increases to -20" of water  at  >  500 MVMZ/hr. An  improved medium mixed with
   coarse bark reduces  the pressure  drop significantly.

   •  Surge and Intermittent Loading

    The filter's  huge  buffer  capacity prevents breakthroughs during peak
   loadings, and allows sizing based on hourly  average rather than
   instantaneous  peak loads.   The buffer capacity of a filter for  a particular
   application will vary depending on water solubility of the target pollutants
   and  surface loading  rates.   Most industrial  sources of air pollutants do not
   operate  continuously.    It has therefore  been of  interest whether the
   biological activity of a biofilter could survive during  extended shut-down
   periods.    It is suggested that filter beds  can survive at least two weeks
   without  any significant reduction in microbial activity.    If sufficient
   nutrients are provided by the filter material, survival  periods  of  up to two
   months can be  expected.

   •  Media

    Compost,  usually produced  from  municipal  waste,  wood chips, bark or
   leaves,    has generally been the basis of filter material  used in recent
   applications in Europe.   Peat and  heather  mixtures  have  also been  used.  The
   bio-filters originally built in the US were mostly "soil-beds" for  which
   biologically active mineral soils  were  used as filter materials. Preferred
   fresh material properties include  a pH  between  7 and  8,  a pore volume of
   greater  than 80%,  and a total organic matter content, measured  as  LOI, of
   >55%.  Activated carbon can be used to  increase  the filter's buffer capacity
   for  emissions from  sources  that  operate only intermittently  This can
   reduce the filter volume significantly.

    Typically, a  compost-based filter material will  provide sufficient
   inorganic nutrients from microorganisms and the addition of nutrient will
   not  be required.   In some  cases,  however, depending upon  the target
   pollutant and  the source of the filter material, the  availability of
   specific  nutrients might become a process limiting factor.   The  fresh media
   are  required to be tested  for potentially hazardous constituents (e.g.,
   heavy metals)  before installation in the filter in order to avoid the
   potential  complication  in  disposal  of spent material.

4 .   Maintenance  Requirement

   The  off-gas must be saturated with water since it would  otherwise remove
 moisture from the filter material resulting in drying of the bed,  the death of
 most  organisms and  a  total loss of control efficiency.  Spray  nozzles usually
 provide  the required  humidity  in the humidification chamber.  Additional
 automatic  irrigation of the filter beds from the top is also used in some
 systems  to maintain the required moisture content in the  filter materials.  A
 useful life for filter materials of up to three to five years has been

-------
reported.   Maintaining the porosity of the compost by  turning it over,  and/or
 replacing  it entirely,  once spent,  are the second major  maintenance
 requirements for biofilters with compost-bed filter materials.

 5. Cost

   The  operating cost is about $0.60 to $1.50  7100,000 ft3  off-gas in  Europe
 $0.30  to  0.60 is reported  in the US.

6.    Future  Improvements

 Reported  failures in the operation of the existing biofilter  include:

       Insufficient treatment due to under size  of the  filter

       Off-gas is toxic to microorganisms, e.g.,  S02

       Insufficient  humidification

       Generation of acidic degradation end-  and by-products  can result in a
   drop in pH and destruction of  the microbial  population.

       Rapid compaction of inappropriate filter material can often, in
   combination with inhomogeneous humidification, result in the formation of
   cracks  and breakthrough  of untreated off-gas.

   Compaction should be kept to a minimum, reducing the need for  maintenance
 and replacement of the filter materials.   Mineralization  of the  organic matter
 in bio-filters will eventually  lead to compaction of the  filter  materials  and
 a corresponding increase in back pressure.  Future  improvement in  the  physical
 properties and longevity of the filter material is needed because  they  will
 result in reduced cost for energy and maintenance.

   In summary,  the use of biofiltration has demonstrated a viable and
 economical way to remove trace contaminants from air.   Elimination of  the
 compaction with an improved filter media and a biomass removal device offers
 an opportunity to  correct  the deficiency of the existing bio-filter.  In
 addition,  the use of the natural media requires a large surface  area, which
 may be a  constraint in certain applications.   The objective of this  study  was
 to develop  an  engineered  medium/filter with  the following features: (1)
 avoidance of the  compaction  of  the medium,  (2)  reusable media,  thus no
 replacement and disposal requirement, (3) more effective, thus can offer a
 space-efficient and more  controlled  filter.  Use of a selected granular
 activated carbon could satisfy  the above need if a proper engineering design
 is built  in to provide a  suitable  environment for bio-growth. A benchscale
 unit was  designed and operated for >11 months successfully  in the lab. The
 result from this operation is discussed in the following.

 consists  of five parallel glass columns (2.5 x 61  cm),  each of which is
 connected to one of two  humidified air streams  (0.5  to 4 1/min). Each  air
 stream  contains  -10 ppm of toluene.

  Three glass columns with 2.5  cm  ID and -60 cm  L were packed with selected
 activated carbons ( US  Mesh 10x14)  as filters.   Four sampling ports were
 installed along  the axial length of the column for gas sampling and pressure
 drop  measurement,  as  shown in Figure 2.  Air containing 10 ppm of toluene  was
 prepared  by diluting  the  custom-premixed gas containing 500 ppm of toluene in
 air.  Flow rates ranging  from 0.5 to 4  liter/min were controlled with MRS  mass
 flow  meters  and  controllers.  Both feed and effluents were sampled with a
 Precision  gas tight 1  ml  syringe,  then analyzed  by gas  chromatography (GC).
 The method of detection limit was determined to  be 0.86 ppm. The analytical
 method  is  detailed in Section V.   Pressure drop  was measured with a
 Monagahelic pressure  gauge (0 to 100" water). Excess  biomass was removed as
 required  by manually  removing,  gently washing and replacing the affected
 carbon  in  Zone A.   Inorganic nutrient, required for biological growth,  was fed
 to  the  column down flow at a 0.1 ml/hr rate.   A  picture of the bench-top unit
 and its delivery system is presented  in  Figure 3.

2.   Influent Air

  The humidified air stream is  prepared  by passing bottled breathing air
 through a Balston cleaner/dryer (type A, BX, DX) and then through a sparging
 bottle  containing  deionized water.   The  sparging bottle temperature is
 maintained by placing the unit  in  a Blue M Magni-Whirl constant temperature
 bath,    The humid air  stream is  split and the flow rates of the two streams are
 controlled by  a  mass  flow controller  (type  1259  MRS,  Inc).  The toluene
 containing  gas,  500  ppm,   is mass controlled and  mixed with an air stream  to
 produce a humidified air  stream containing 10 ppm toluene (refer to Figure 1).

  The humidity and temperature of the two influent streams is continuously
 monitored by in-line  Panametrics moisture probes  (type M2LRT) connected to a
 Panametrics  System I  hygrometer,  interfaced to a two-channel strip chart
 recorder.    A septum port  is connected at  the outlet of  each probe assembly to
 facilitate syringe sampling of  each toluene-laden stream  at  specified
 intervals.   Each air stream is  separately connected to manifolded Cole/Parmer
 rotameter/controllers  and  split  into five  isolated  streams (refer to Figure
 2).   These streams are defined as the influent to each column.

 3.  Filter  Configuration

  The five columns are  identical with respect to materials of construction.
 Each  is a 2.5  x  61 cm ACE Glass Inc air sampling manifold with two threaded
 (nylon) sampling  ports attached at 1/4  and 1/2  the length of the tube. The
 threaded  endcaps are  PTFE with  1/4" NPT female outlets.  A 304  SS screen (20  x
 20  mesh)  is placed on top of the bottom endcap to support the granular
 activated  carbon (GAC).   The effective volume of each column is -295 ml.

  The branched inlet to each column provides connections for influent, pumped
 nutrient  solution, and  a  pressure  gauge to monitor back pressure in the
 column.    The outlet tubing is open to the  atmosphere except when connected to
 the effluent sampling chamber.

 Figure 3. A Bench-Scale BioScrubber Unit with Gas Delivery System
  The effluent sampling chamber consists of an in-line Panametrics moisture
probe assembly with a septum port connection on the outlet of the probe
assembly.   This chamber provided effluent humidity and temperature data and a
convenient port at the specified sampling  interval.  There is only one
effluent sampling chamber for all effluent columns.   The  chamber  is connected
to the column of interest and purged for 2 minutes prior to sampling.

  All tubing is 1/4"  TFE with 316 SS connections and PTFE ferrules. All
wetted parts in the sampling chamber and gauges are either 316 SS, nickel,
viton, or PTFE.   Again, silicon rubber septa (Supelco Thermogreen™ LB-2) are
used in place of PTFE-backed septa in both the chamber and column sampling
ports.   Columns A & C contained wood-based GAC from Westvaco, screened to a 10
x 14 standard mesh size.   Coal-based GAC from Calgon Carbon with the same mesh
size was packed in Columns B, D & E.  The  carbon loading  in  each  column is
listed in Table 1.

C.    INOCULATION

   Prior to 1992,  the bio-scrubbers were operated successfully and steadily for
 a period of 3 months before  the  decay of the removal efficiency. Our
 diagnosis concluded that channeling of the air flow, drying of the filter
 media,  and a poor inoculation procedure were the possible sources of the
 activity decline.  An improved inoculation and maintenance procedure was
 developed,  which led to  a steady operation for > 11 months.  This improved
 inoculation is summarized as follows.

   In the first quarter of 1992,  five bio-scrubbers were re-inoculated. A new
 inoculation procedure was developed  to solve the problem of air  channeling  in
 the carbon bed.  A dilute benzoic  acid solution, listed in  Table 2, supported
 the growth of the biomass and allowed for impregnation without clogging the
 pore of the carbon.  The  inoculation procedure consisted of adding 100 ml of
 activated sludge, collected from a local sewage plant, to the benzoic  acid
 media in batch mode and allowed to feed on its nutrients for 5 days before  it
 was poured into the carbon columns.   Biological growth  in the  inoculum was
 monitored visually insuring the success of the incubation.   The  biofilter was
 fed an  -10 ppm toluene/air mixture at the rate of  0.5  1/min during its five
 day incubation period.    Table 3 shows the concentration history during the

 incubation.   The  initial  feed concentrations reached  550  mg/1; by the  fifth
day, column  B had a COD concentration  range  of 2050 mg/L.  Column influents
remained in  the range  of  10  ppm with an occasional fluctuation approaching 30
ppm.   All  influent variation was corrected  immediately without causing any
alteration in column performance.

  No toluene breakthrough was reported  in the effluent of Columns A and C for
the first  1.5 months of operation.   The biomass supported  on the GAC allowed
the feed to  be  completely consumed with its 5 cm  length from the influent to
the first port.   As  shown in figure 4,  operation  of the bioscrubbers continued
with complete toluene  removal by Port C for all  columns.

  In addition, an  inorganic  nutrient was supplemented to  the column for the
inorganic requirement to sustain the bio-growth. The inorganic  aqueous
solution provides  additional  humidification of the contaminated air within the
filter.   The composition and flow  rates were  described in  Table  4.

D.   RESULTS

    The columns consistently  degraded  the  contaminant for a period of  >11
 months.   They have achieved a > 95% removal efficiency within the first  5  to
 10  inches of the  carbon  bed.   A stationary mass transfer zone was observed
 with  an empty bed contact time (EBCT)  of 1 to 4 seconds depending on flow
 rates.  This performance indicates the effectiveness and efficiency of the
 bioscrubbers  developed in this program.

 1.  Removal During  Inoculation

    Since  the columns were  pre-saturated with -10  ppm of toluene in air prior
 to  inoculation,  the removal of toluene immediately  after  inoculation  on
 3/23/92 was  attributed to the biodegradation of the microorganism  inoculated
 on  the carbon support.   The roll-over of  the pre-adsorbed  toluene  on  the
 carbon was observed in  Column C  on 3/23  (Figure  4). Approximately 0 ppm of
 toluene was  observed at  Ports A & B; while about 6  ppm of  toluene was  observed
 at  Port C with a feed concentration around 10 ppm on the same day.    Evidently,
 the roll-over was resulted from desorption of  the pre-adsorbed  toluene along
 the axial direction of the column.   The bio-digestion was  not capable  of
 degrading all toluene pre-adsorbed on the carbon, which  then desorbed  suddenly
 due to the new adsorption  equilibrium established by the  inoculum. Since  no
 toluene was  observed for Ports A & B,  the removal of toluene by
 bio-degradation rather  than  carbon  adsorption was  obvious.  A similar
 phenomenon was observed  for Column  B  as shown in Figure 5.  In this case,  the
 roll-over declined and disappeared for a  slightly longer period,  i.e., ~2
 weeks for Ports A & B  and ~5  weeks  for Port C.   In conclusion, the removal of
 toluene by the bio-filter is evident based upon the roll-over phenomenon
 observed  during the initial  inoculation.    Infield  start-up  operation, no
 roll-over will be observed since the contaminants need not be pre-adsorbed and
 biodegradation will  take place immediately.

2.    Biodegradation  Efficiency

    Five  columns have been  operating since 3/23/92 until  the present (February
 1993).  All  columns were fed with 0.5 liters/minute of air containing  -10  ppm
 of  toluene as a target  concentration from 3/23 to  6/30/92 The actual feed
 concentration fluctuated from 5 to 40  ppm  as shown  in Figure 6-10, while most
 of  the time  it stayed between  10 to 20 ppm.  During this period, no toluene
 breakthrough was observed at Port A, indicating the effective mass transfer
 zone  was  less than 5 inches, equivalent to > 19 g/M3/hr  of biodegradation
 efficiency.   More importantly, the mass transfer zone remained stationary  for
 the entire period.   Biodegradation of toluene evidently was  effective  and
 complete,   showing no signs of accumulation of contaminants or the metabolic
 by-products.    Bioregeneration of activated carbon has been discussed in  the
 literature as a means  to prolong the GAC service life in water and waste water
 treatment10'11-  This study extends the similar concept to  air  pollution
 control with the  aid of  a proper engineering design which offers a suitable
 environment  for  biogrowth.

-------
3   Effect of Flow  Rate

    After the successful demonstration of the concept, several additional
operating conditions were studied.   The flow rates for Columns A and B were
increased to  1  liter/minute  and  then 2  liters/minute (Figures 6 & 7) while
Columns C, D &  E remained at the original  flow of 0.5 liter/minute (Figures 8,
9, & 10, respectively) to act as a control.   The empty bed contact time (EBCT)
under the 2  liter/minute flow rate is about  2  seconds.   During this period
(8/05 to 1/27/93 for Column  A and 8/10/92 to 10/9/92 for Column B) ,  both show
some breakthrough ranging from 0 to  5 ppm  at Port A (Figures 6 & 7).
Nevertheless, no toluene was detected at Port B  in  each column.  The effective
mass transfer zone was estimated to  be  about 7.5  inches  and remained
stationary for  the  entire period.   This efficiency was equivalent to 51
g/M3/hr  of biodegradation of toluene.   Column  B was  further challenged by
increasing the  flow rate to 4 liters/min,  equivalent to 1 second of EBCT from
10/9/92 to  1/21/93.    No contaminant breakthrough at Port B was observed for
the majority  of the experimental period. In certain instances,  i.e.,  on
December 30, 1992 and January 18, 1993,  trace  breakthroughs were observed,  but
the column rapidly  recovered to its  typical efficiency.  The breakthroughs
were possibly due to  channeling  of the flow. The  mass transfer  zone was
estimated to be approximately 10 inches at  this  flow rate, equivalent to 80
g/M3/hr  of toluene.   The flow rate of Column B was subsequently  reduced  to  0.5
liters/minute on 1/21/93 no toluene breakthrough was detected at Port  B as
had been observed previously.   The  recovery of the column to the original mass
transfer zone indicates that the increase  of the  mass transfer zone from 5 to
10" is  possibly due to  the degradation  kinetics  vs.  linear velocity of the
contaminant.   Therefore, the mass transfer zone is concluded to be stationary
throughout the  entire study.

    According to the literature,   the degradation  rate for  toluene by existing
biofilters  is 20-30 g/M3/hr  for  concentrations £ 200 ppm. A nearly linear
relationship between degradation rate vs.  concentration was reported  for
concentrations  <200 ppm.   The performance  observed in Columns A,  B and C
indicates a  40  to 80  times  higher degradation rate than existing filters with
naturally occurring media.   This enhanced  degradation is  at  least partially
attributed to the adsorption function performed by the activated carbon
medium.

    Since no significant difference was observed  between Columns  A  & C with  a
wood-based carbon and Columns B,  D  & E with a coal-based  carbon for the entire
operation period,  it  is believed that either carbon  could deliver a similar
performance under the testing conditions studied  thus far.  A  long  term study
is  required to  assess the attrition  loss of the  carbon.

4.  Feed Fluctuation

    The biofilter adequately adsorbed fluctuations in the influent ranging
from 0  to 45  ppm for  the majority of the study.  The fluctuation observed in
the influent was not  reflected  in the analysis of Ports A and/or B, indicating
that activated  carbon effectively acted as  a sink to adsorb the temporary
concentration  increases.  This  toluene "sink"  was then, subsequently,  digested
by the  microorganisms during normal  operation  and/or concentration in
decreases.

5.  Pressure  Drop and Bio-mass Build-up

    The biomass generated and accumulated in the filter as  a  result  of the
degradation  of contaminants was expected.   Biomass was visually detected
occupying the  interparticle space.   This build-up would essentially result  in
a pressure drop  increase.   Occasional removal  of the biomass manually  was
practiced to maintain  a minimal pressure drop  throughout the operation period.
While  the excess biomass was  removed from the column, sufficient amounts  of
biomass were retained  on the  carbon to maintain effective  biodegradation  when
the bed was  replaced.   The biofilter efficiency was not reduced as  a  result of
the biomass  removal  as  indicated  in  Figures 6  to  10.

    Pressure drop through the bio-scrubber is  very minimal  due  to the  shallow
bed requirement  to contain the stationary mass  transfer zone.  However, if  the
bio-mass build-up becomes significant,  the pressure drop could increase
dramatically and become an operational  problem.  Pressure drop experienced
during the 11 months of operation is  discussed in detail  here.

    Pressure  drop experienced in Column C with a flow rate  of 0.5 liter/min.
is presented in  Figure  11.   The pressure drop measured here  is the  difference
between the  inlet and  the outlet  of the entire column,  including the 25 inches
of the packed  column,  the fittings,  and entrance and exit effects.   Initially
the pressure drop throughout  the  entire column is  « 10  inches  of water until
the end of June.    Then  the  pressure  drop increased  significantly to the level
of 60  and then 100 inches of water.    After that,  the pressure drop returned  to
the 10 to 20 inch level  or  even to  close to  0  inches in January and February
of 1993.   It is  believed that the turbulent  pressure drop observed between
July and September of 1992 resulted from the bio-mass' build-up in the  inlet
and channeling of the air flow in the presence of the aqueous nutrient
trickling down the column.  Since the build-up may  be sloughed-off and/or the
channeling may be rearranged,  the pressure drop measured fluctuated
significantly and at an  unsteady  state.   The  carbon from inlet to Port A was
removed and  washed to get rid of  the bio-mass  accumulation on October  21,
1992.   The pressure  drop  since then  has been  maintained at < 20 inches of
water.   It is  concluded that  the  pressure drop in a bioscrubber is very
minimal,  i.e.,  between  0  to 20  inches most of the time at the flow rate of 0.5
liters/min.   The pressure drop could be reduced through  the removal  of the
biomass accumulation in the carbon.   This is  one of the advantages of  the
engineered filter over  the  existing  compost-type filter,  where the compaction
of the bed eventually develops and the  replacement  of the bed is required.

    The pressure  drop in  Column B is presented in Figure 12. It shows  that
the pressure drop is between  5 to 15 inches for most of the time with  the flow
rate at 1 liter/minute.   The  pressure drop observed seemed not correlated with
the flow rate  increase  from 1 to  2  and then 4  liters/min.  In most of  the
period the pressure  drop  was  between 0  to  20  inches  along with the  occasional
washing of the carbon as  indicated in the figure.   The washing of the  column
was performed as  necessary to maintain  the low pressure  drop  in the  column.
Pressure drop  in Column A showed  a similar trend with the pressure  drop
observed ranging  from 0 to 25  inches  of water  for most  of the time  (Figure
13).    Occasional  washing  of the carbon  may help in  curtailing the increase of
the pressure  drop of the  column.

-------
    In summary,  the pressure  drop  experienced in the  bench-scale bio-scrubber
ranged from 0 to 20  inches of water for most of the time for the flow rate
from 0.5 to 4 liter/min.  The pressure drop experienced here approximates the
drop reported in the literature with a  conventional  media.  The pressure drop
is believed to be primarily  attributed to the bio-mass build-up, which can be
controlled via washing of the carbon.   Occasional  washing of the column as
necessary was practiced in this study.   An automatic washing device was
designed for a field unit, which could deliver a much-reduced pressure drop..


V.    PILOT  UNIT

    The pilot bioscrubber developed in this program is  as simple as  a  carbon
adsorber system incorporated with  a nutrient delivery system and a biomass
removal capability (Figures   14 &  15).    Due to the simple configuration,  it
can  be  integrated  into  existing production processes or added  downstream  from
existing remediation processes,  such as air stripping towers,  soil vacuum
vents, biological wastewater treatment,  etc.   The system consists of  four
major components:  (1) a gas  delivery system, (2) the biofilter,  (3) a nutrient
delivery system and  (4) a bio-mass removal  system.  Through our extended
operating  experience an advanced engineered and filtration technology has been
incorporated  into  the pilot  testing unit to become a reliable  and user
friendly biological  treatment  system.   The gas delivery system sends  the field
gas  stream from the  customer's site to the unit via a gas distribution plate
to ensure  even  distribution  through the biofilter. Due  to  the  short mass
transfer zone in the biofilter,  the bed depth requirement is very shallow and
the  need for a gas booster fan,  if necessary at all,  is minimal.  Feed  streams
must be cooled to  100*F or less  prior to entering the biofilter because the
bacteria within the  filter  cannot be  exposed to high temperatures.  Other
pre-treatment, such  as  particulate removal,  may be necessary if substantial
particulates  are present in  the feed.   Due to the build-in bio-mass removal
capability, the system  can tolerate a higher particulate concentration than
most  existing filters.

    The biofilter is a  very  shallow granular activated  carbon  adsorber.  The
microbes are inoculated onto the  carbon surface,  which usually takes about 2
weeks during start-up in  order to  ensure a sufficient microbial population.
Bed-depth  of  ~2  feet and EBCT of  1  to 4 seconds are normally  required to
ensure the confinement  of the mass transfer zone of the contaminant within the
bed.   The  actual dimensions  may vary depending upon the feed concentration and
its  biodegradability.

    An automatic nutrient delivery system  is  part  of the advanced engineering
package of the pilot unit.   The feed stream contaminants provide the  primary
organic carbon source for biogrowth,  however,  inorganic nutrients are also
required for optimal growth.   A unique nutrient delivery system with
recirculation has  been  implemented to provide proper inorganic nutrients with
no  secondary  pollution.   Nitrogen and phosphate are mixed into a solution and
automatically delivered to the biofilter at preset intervals.    The  system is
flexible in supplementing additional organic nutrients to (1)  maintain the
biofilter  during an  extended downtime,  or (2) enhance degradation for
recalcitrant contaminants via co-metabolism.

  The bio-mass removal device is one of the  unique  features  of the developed
biofilter, which  differentiates  ours from existing biofilters.  The device
introduces aqueous backwashing via  a high pressure  nozzle to discharge the
excess bio-mass periodically out of the biofilter.   The discharge is further
filtered before discharging  into the local sewage treatment system.  Due  to
the extreme efficiency of the bio-degradation,  no additional post-treatment of
the aqueous discharge is expected.

  In summary, the developed  pilot testing unit  offers  a unique engineering
design to make biological treatment  a  simple and reliable operation, which is
often perceived as an extensive  "baby-sitting" operation in the waste
treatment community.   In addition,  the  utilization of  an activated medium as a
bio-filter media  enhances the bio-degradation efficiency, which minimizes
filter dimensions and reduces capital  and operating costs.

VI. QUALITY ASSURANCE

  Toluene concentration was  determined by gas chromatography.  The
methodology, calibration curve and  method of detection limit are detailed
below:

A . Calibration Curve

     The  following data were obtained  by  injecting  fixed volumes of certified
standard gas mixtures (Matheson  Gas  Products)  (see Appendix  A) into an HP 5995
GC/MS equipped with  an HP  18965A FID detector.

      Conditions Used

      1.     Column: 6' x  1/8" SS packed with  5% SP 1200, 1.75% Bentone 34 on
  100/200  Supelcoport.

      2.    Oven Temperature Program:  75'C   isothermal

      3 .    Injection Port  Temperature:   200"C

      4.    FID  Temperature:   200'C

      5.    Carrier Gas:  Helium at 20 scc/min

      6.     Injection Volume:  500 /il

  Calibration standards  consisted of 1.0,  10.0 and 20.0 ppm toluene  in
hydrocarbon free air.   Calibration standards  were  purchased  for purity and all
standards were verified by  the  USEPA audit standards  when  available.  Accuracy
is certified  by the  supplier to ± 5% of the  specific component.  Concentration
tolerance  is ± 20%.   Calibration was verified on a daily basis through the
analysis of a 10 ppm standard.   If the determined  concentration differed from
the previous  calibration  value  by  more than  5%,  the source of error was
detected,  corrected and  noted.

  In April,  1992, the analysis  was  switched to a Varian  (Model 3400) Gas
Chromatograph equipped with a  signal  integrator compatible with a flame
ionization  detector (FID) output.   The Varian oven is capable of maintaining
an isothermal 75"C +1.0 and an injection  port temperature of 200'C. 500 /il
samples were  extracted  in a 1000 /il  (application range 0.1-40 ppm) gas tight
syringe were  injected onto  60/80 Carbopack B, 1% SP-1000 column with a
detection limit of 0.1 ppm.    Compressed gases running through the system
consisted of  zero grade air and ultra-high purity  helium and  hydrogen.

  Column conditioning was conducted by heating  the column for a minimum of 18
hours at 25-50"C below  the  maximum packing temperature with  carrier flow  and
vented to atmosphere.   After cooling  the  column to ambient temperature, the
carrier flow was shut off.   After  15  minutes, the  column was connected to the
detector inlet with suitable fittings  and  checked  for leaks.

  After  conditioning,  the  hydrogen and air flow were  adjusted according to  the
manufacturer's specifications for the  column.   Column temperature and carrier
flow were adjusted to the desired  operating  levels and the FID was  ignited
according to  the manufacturers  instructions.    The  baseline output was
monitored with a recording  device until the signal drift was  equilibrated.


  The  toluene peak  appears typically between  3.55 to 3.60 minutes.
Calibration curves can be generated from measured  area or  height of standard
peaks obtained  from a strip chart  recorder or direct  integrator quantitation
In our case, response  factors for calibration  standards  were  entered into a
Varian (model 4270, Figure  4)  integrator  for  direct quantitation of the
to1uene samp1es.
                                     29

  The  syringe  was filled using a septum  bag.  Samples were injected and
 analyzed according to the calibration curve.   If duplicate sample data was
 required, the sample was not taken directly from the  septum port,  but
 collected in a Tedlar bag.

 B  Sampling

  A 500/il gas-tight  syringe  was purged with air first  and  the  microvalve at
 the  end of the syringe was  then closed.    The  syringe  was  inserted through
 the  septum of the  1.0 ppm  standard  Tedlar bag. The valve on  the syringe  was
 opened.   The syringe was then  filled  and purged three  times. The  syringe was
 filled with the sample a  fourth time and  the valve was closed. The needle  was
 inserted into  the port of the GC.    The  microvalve was  reopened and the sample
 was  injected.   This process was repeated three times  for the  1  ppm standard as
 well  as the 10 and 20 ppm standards.

C.   Method  Detection Limit

  The  method detection limit  (MDL)  is  defined as the value obtained when the
 standard deviation of the  instrument noise  is  factored  by three and divided by
 the  slope of the calibration curve.   The slope of  the calibration  curve  is
 easily obtained.  With "modern"  integration equipment,  this  slope  is usually
 defined as  the  ratio  of  the  peak area and the concentration. Unfortunately,
 it is difficult  to  correlate an  absolute noise level (/iv)  with this calculated
 slope.   In addition,  the  document defines the  instrument noise  as  being
 "adjacent in retention time"  to the analyte peak.   In practice,  this value is
 difficult to  obtain with the  configured integration equipment. In an  effort
 to overcome these difficulties, the following  procedures  were employed to
 obtain compatible instrument noise and calibration slope values.

 Instrument Noise

  The  average  instrument  noise was plotted prior to  injection at very  low
 attenuation (full scale =  32 /iv; see plot A of Figure 16).

  The  instrument noise "adjacent  in  retention time" was determined by
 subtracting absolute detector  output values obtained during  calibration runs
 from the stable  detector output  prior to the  injections. Eighteen (18)  /1V
 values were averaged over  three  runs  (see plots C, D,  and E  of Figure 15). B
 is a plot without an injection at the same attenuation.

Calibration Slope

  Three  calibration runs  were made in  peak height mode using  a  10 ppm
 calibration standard  (see  plots C, D,  and E) .  The peak heights of the three
 toluene peaks were  averaged  and  converted to  an absolute /iV  value. The slope
 of the line was  calculated from this average /ZV value.
