                RESEARCH REPORTING SERIES

Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology.  Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:

      1.   Environmental  Health Effects Research
      2.   Environmental  Protection Technology
      3.   Ecological Research
      4.   Environmental  Monitoring
      5.   Socioeconomic Environmental Studies
      6.   Scientific and Technical Assessment Reports (STAR)
      7.   Interagency Energy-Environment Research and Development
      8.   "Special" Reports
      9.   Miscellaneous Reports

This report has been assigned to the  ENVIRONMENTAL PROTECTION TECH-
NOLOGY series. This series describes research performed to develop and dem-
onstrate instrumentation, equipment, and methodology to repair or prevent en-
vironmental degradation from point and non-point sources of pollution. This work
provides the new or improved technology required for the control and treatment
of pollution sources to meet environmental quality standards.

                                  FOREWORD

     The Environmental Protection Agency was created because of increasing
public and government concern about the dangers of pollution to the health
and welfare of the American people.  Noxious air, foul water, and spoiled
land are tragic testimony to the deterioration of our natural environment.
The complexity of that environment and the interplay between its components
require a concentrated and integrated attack on the problem.

     Research and development is that necessary first step in problem
solution and it involves defining the problem, measuring its impact, and
searching for solutions.  The Municipal Environmental Research Laboratory
develops new and improved technology and systems for the prevention,
treatment, and management of wastewater and solid and hazardous waste
pollutant discharges from municipal and community sources, for the preserva-
tion and treatment of public drinking water supplies, and to minimize the
adverse economic, social, health, and aesthetic effects of pollution.  This
publication is one of the products of that research; a most vital communica-
tions link between the researcher and the user community.

     This report presents the results obtained and conclusions drawn from
pilot plant filtration research on the removal of naturally occurring
asbestiform fibers from a protected mountain water source.  Appendix B
contains photographs of equipment; data on operating conditions, water
quality, fiber counting, and filter media; information on treatment of turbid
water; results of sludge generation studies; and detailed documentation of
cost estimating information.  Appendix C presents information on environmental
conditions of each filter run.

                                  ABSTRACT

     Pilot plant research conducted during 1977 and 1978 demonstrated that both
 amphibole and chrysotile asbestos can be removed using direct filtration tech-
 niques at filter loading rates as high as 10 gpm/ft2.  Since asbestos fibers,
 especially chrysotile, were found to be quite sensitive to changes in the
 treatment process, vigilant control over chemical additions and finished
 water turbidity is a necessity.  During the study, engineering data were also
 obtained for making cost estimates for construction and operation of a 100 MGD
 granular media filtration plant.
     Photographs of pilot plant apparatus are contained in Appendix B-l.  It
 includes pictures of the existing facilities on the Tolt, the Waterboy pilot
 plant and piping, mixers, storage tanks and sludge settling basins.  Weather
 and operating conditions at the South Fork Tolt Reservoir are presented in
 Appendix B-2.  It contains water and air temperatures, valve operations and
 flow conditions.  Appendix B-3 includes information from the manufacturers on
 granular media filters and various graphs of water production efficiencies.
     Both amphibole and chrysotile asbestos fibers are in the micron size range
 and require that electron microscopy techniques be used for counting.  Appendix
 B-4 contains micrographs of these fibers.  Appendix B-5 contains information
 on  particle counts and turbidity from various filter runs.
     To determine the capabilities of direct filtration treatment techniques
 at  treating water with abnormally high raw water turbidities, tests were
 conducted on water with a turbidity as high as 34 NTU.  The treatment tech-
 niques could consistently remove turbidity from 20 NTU down to < 0.5 NTU.
 Appendix B-6 contains a description of these pilot tests.

     Water pollution laws now require treatment of wastes generated at water
 filtration facilities.  Pilot settling tests were conducted on sludge gener-
 ated from backwashing the Waterboy granular media filter.  The tests indicate
 that a sludge with a concentration of 2-3% can be produced by gravity settling.
 Appendix B-7 contains details of the settling tests.

     Based on design criteria developed during the filtration studies, CH2M/
 Hill Consulting Engineers developed treatment plant costs.  Construction costs
 were estimated at $24,747,000 and annual operation and maintenance costs were
 $1,212,000.  Appendix B-8 contains details on the development of the costs.
     To document the conditions surrounding each pilot filter run, Appendix C
 contains a description of the treatment trains, mixing intensities, physical
 and  chemical properties of the water and data on water production efficiencies.

     This report was submitted in fulfillment of Grant No. 804422 by the
 Seattle Water Department under the sponsorship of the U.S. Environmental
Protection Agency.  This report covers a period from May,  1976 to November,
 1978 and work was completed March, 1979.

The following recommendations are made with the best information available at the time. Specific applications
may result in various solids loading and filtration characteristics which may necessitate a change in filter bed. For
this reason, we request the individual responsible for conducting filtration tests provide periodic data to The Tur-
bitrol Company for complete evaluation. Based on subsequent test analysis and results Turbitrol engineers may
recommend changes in filter media bed design or gradation.

Based on the information supplied to Turbitrol the intended filter bed will be utilized for the following test filter

           FILTER RUN PILOT TESTING AT HIGH RAW WATER TURBIDITIES


                                 I.  SUMMARY

      Pilot tests were conducted to determine if direct filtration techniques
 could effectively treat  water with abnormally high raw water turbidities.
 These tests  indicated that such techniques could produce an acceptable
 quality  finished water when raw water turbidity was less than approximately
 20 NTU.

                              II.  INTRODUCTION

 Purpose
      The purposes of this phase of the asbestos removal study were to
 determine  (1) if the process flow schematic consisting of a static mixer,
 a flocculation chamber and a granular media filter could effectively remove
 abnormally high raw water turbidities;  (2) what practical upper limit of
 raw water turbidity could be removed; and  (3) which of the test medias was
 most  effective under the stressed conditions.

 Goals

      To  effectively remove asbestos particles from the raw water, the filtra-
 tion  process had to remove turbidity down to levels which were < 0.1 NTU.
 Since turbid water conditions are normally short term phenomena resulting
 from  landslides or flooding, the turbidity goal in the finished water was
 changed.  Rather than attempting to produce a finished water turbidity of
 < 0.1 NTU, the desired goal was increased to 0.5 NTU, which is still well
 below the maximum contaminant level of 1.0 NTU set forth by the National
 Interim  Primary Drinking Water Regulations.  This less stringent goal was
 justifiable during emergencies since it would be more important to produce
 a safe water by today's standards rather than removing all asbestos particles
 from  the water.

Methods  and Equipment

      To  achieve the high turbidities, soil from the banks of the South Fork
Tolt  Reservoir was gathered and mixed with raw Tolt water.  The slurry was
allowed  to settle to remove heavy suspended material and the supernatant was
decanted into another container for feeding into the pilot plant.  Equipment
limitations prohibited the investigator from injecting the slurry at a point
upstream of the static mixer and consequently it was fed directly into the
head  end of the flocculation chamber.  Raw water turbidities between 5 and
34 NTU were achieved using these methods.

General

     Data from filter runs conducted at the abnormally high raw water tur-
bidities is presented in Table B6-1 and plots of headless and turbidity vs.
time are contained in Figures B6-1 through B6-21.

Water Quality

     The data indicate that direct filtration techniques using a static mixer,
a flocculation chamber and a granular media filter can significantly reduce
excessive turbidity present in the raw water.  Using 10 mg/1 of alum, lime for
pH control and a nonionic polymer as a filter aid, direct filtration methods
reduced raw water turbidities of 20 NTU down to < 0.5 NTU.  Raw water tur-
bidities > 20 NTU could be reduced but finished waters exceeded 0.5 NTU after
filtration.  It is likely that chemical feed rates could be adjusted to
effectively remove raw water turbidities that are >20 NTU but such an evalua-
tion was beyond the scope of this study.

Water Production

     Most of the filter runs were conducted at a moderate filter loading rate
of about 4 gpm/ft2.  Normally, as the raw water turbidities increased, both
the length of the filter run and the filter efficiency decreased.  Utilizing
direct filtration techniques at these high raw water turbidities was not
expected to be a very efficient method of operation but the tests demon-
strated that an acceptable quality finished water could be produced for
short periods of time at moderate loading rates.  The coarse coal dual media
generally produced more water per filter run than either dual media with
fine coal or the mixed media filter.
                              IV.  CONCLUSIONS

     Treatment  techniques  similar to  those which remove asbestos fibers from
Tolt water can  be used  to  reduce abnormally high raw water turbidities  (20
NTU) down to <  0.5 NTU  in  the finished water.   Direct  filtration techniques
are inefficient under such raw water  conditions but can produce potable water
for a short period of time until the  turbidity  recedes.  Dual media with
coarse coal was the most effective  filter media.

                       SLUDGE SETTLEABILITY TESTING
                              I.  INTRODUCTION

     To assess the settling characteristics of the solids present in the
backwash wastewater, sludge settling tests were conducted.  Backwash waste-
water was discharged into a settling basin where the solids would settle
and accumulate.  The clear supernatent was periodically drawn off and
discharged to the North Fork Tolt River.  Near the end of the pilot testing
phase; the solids, which had been accumulating for about one year, were
collected in a 55-gallori drum and transported to the Water Quality Laboratory.
Settling tests were initially performed using a small, 2-liter, graduated
cylinder and subsequently using a larger 6-inch diameter settling column.
The column was equipped with a stirring mechanism that rotated at 1 RPM to
facilitate movement of the water up through the solids.  Various concentra-
tions of sludge were prepared and added to the graduated cylinder or column.
The downward velocity of the liquid-solids interface was measured at various
time intervals.  From this data, batch settling curves were prepared and
were used to estimate the minimum surface area of the clarifier-thickener.
                                II.  RESULTS

     The results of the settling tests are listed in the tables below and
are illustrated in Figures B7-1 through B7-4.  Review of this information
indicates that the solids generated during the filter backwashing process
can be thickened to a concentration of 2-3% by gravity thickening methods.

 16. ABSTRACT
       For 1 1/2 years the  Seattle Water Department conducted direct  filtration pilot
  plant studies at the Tolt Reservoir, obtaining data on techniques to remove  amphibole
  and chrysotile asbestos from drinking water.  Research showed that  filtered  water
  turbidity should be 0.1 ntu or lower in order to effectively remove fibers.   Floccula-
  tion was necessary but sedimentation was not.  Amphibole fibers are more  readily
  removed than chrysotile,  but both types could be reduced to below detectable limits or
  to  not statistically significant counts by treatment with alum, lime and  a filter aid
  (nonionic or anionic polymer); or alum, cationic polymer and a filter  aid; or cationic
  polymer and a filter aid.   Asbestos fiber content of filtered water increased sharply
  when filtered water turbidity rose above 0.10 ntu.  Asbestos fibers in the concentra-
  tions encountered in this study (raw up to 20 x 10  f/L, filtered down to 0.01 x 10
  f/L)  can not be detected  by a turbidimeter; however, the association of rising fiber
  counts and turbidities in filtered water would enable a plant operator to estimate
  fiber removal by observing turbidity if the filter was operated in  the manner done in
  this work.  Appendix B contains equipment photographs; data on operating  conditions,
  water quality, fiber counting, and filter media; turbid water test  data;  results of
  sludge studies; and documentation of cost estimation data.  Appendix C has details on
  conditions for each filter run.
