ABSTRACT
Bioslurry treatment of poiycyclic aromatic hydrocarbon (FAH)-impacted soils was demonstrated
under the Superfund Innovative Technologies Evaluation - Emerging Technologies Program (SITE
ETP) as an evasion of research previously funded by IT Corporation (IT) (Brown and Sanseverino,
1993) and additional investigations supported by the U.S. Environmental Protection Agency (EPA)
(Davila et al., 1994).
During the demonstration, IT operated two 60-liter (L) TEKNO Associates bioslurry reactors
(Salt Lake City, Utah) and a 10-L fermentation unit in semicontinuous, plug-flow mode for a 2-month
period. The first 60-L reactor received fresh feed daily and supplements of salicylate and succinate to
enhance PAH biodegradation.
Effluent from the first reactor was fed to the second 10-L reactor in series, where Fenton's
reagent was added to accelerate oxidation of four- to six-ring PAH. The third reactor in series was
used as a polishing reactor for the removal of any partially-oxidized contaminants remaining following
addition of Fenton's reagent.
During operation, the bioslurry reactor system demonstrated average PAH and carcinogfnic
PAH (CPAH) removals of 84 and 66 percent, respectively, The reactors will be operated over the
1

-------
next four months to increase the rate and extent of PAH biodegradation. The objective of the
demonstration is to illustrate bioslurry treatment of impacted soils and sludges as an effective and
economically attractive remedial option.
INTRODUCTION
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
mandates the EPA to select remedies that "utilize p uanent solutions and alternative treatment
technologies or resource recovery technologies to the maximum extent practicable." CERCLA also
prefers remedial actions in which treatment that "permanently and significantly reduces the volume,
toxicity or mobility of the hazardous substances, pollutants, and contaminants is a principal element."
During this demonstration, innovative methods for the biological treatment of PAH-impacted soils
were evaluated to determine their compliance with the mandates of CERCLA,
The primary objective of reactor 1 (Rl) operation was to increase the biological removal of
organic carbon. Salicylate was used to induce the naphthalene degradation operon on NAH plasmids.
This system has been shown to degrade phenanthrene and anthracene (Sanseverino et al., 1993). The
naphthalene pathway may also play a role in CPAH metabolism. Succinate, a byproduct of
naphthalene metabolism, served as a general carbon source during this investigation. The first reactor
in series removed easily degradable carbon and increased biological activity against more recalcitrant
PAH (i.e., three-ring compounds and higher).
Effluent from Rl was fed to reactor 2 (R2) where Fcnton's reagent was continuously
introduced. Fenton's reagent (hydrogen peroxide In the presence of iron salts) produces a free radical
2

-------
which has been shown effective in extensively oxidizing multi-rm- aromatic hydrocarbons (Gauger et
al., 1990; Elizardo, 1991). The objective of Fenton's reagent addition was not PAH mineralization,
but the hydroxylation of multi-ring PAH, since hydroxylation of high molecular weight PAH is
generally the rate limiting step in biological oxidation.
Reactor 3 (R3) was used for biological polishing of R2 effluent. Overall, the primary objective
of the investigation was to demonstrate increased CPAH and PAH removal using combined biological
and chemical oxidation.
MATERIALS AND METHODS
Impacted soils with PAH and CPAH concentrations of 4,380 and 300 milligrams per kilogram
(mg/kg), respectively, were collected from a Southeastern wood treating facility. Soils were wet
sieved on site and submitted to IT's Biotechnology Applications Center (BAC) located in Knoxville,
Tennessee for testing.
Prior to bioslurry treatment, soils were wet sieved to less than 30 mesh. All reactors were
charged with a 40 percent total solids (TS) slurry of the screened soils and operated in batch for a
period of two weeks prior to the initiation of semi-continuous flow. During batch treatment, several
operational difficulties were encountered including, significant foaming and tar ball formation.
During semi-continuous flow 6 liters per day (L/day) of influent slurry was manually introduced
io Rl, resulting in a hydraulic retention time (HRT) of 10 days. To induce biological activity against
PAH salicylate and succinate were added, weekly to achieve a final reactor concentration of 86 and
3

-------
4.4 milligrams per liter (mg/L), respectively. This addition rate was increased to 3 times per week
following 4 weeks of operation. Reactor pH, dissolved oxygen, ammoniacal nitrogen, and ortho-
phosphate concentrations were maintained at optimal for biological activity.
The second reactor in series received dilute concentrations of Fenton's reagent to accelerate
oxidation of multi-ring PAH. Fenton's reagent was prepared by mixing a 1:1 ratio of 35 percent
hydrogen peroxide and 1.5 molar (M) iron sulfate solution, Fenton's reagent was applied to R2 at
2.0 L/day. The influent feed rate to R2 was 6 L/day resulting in a substrate HRT of 1 day; the total
system HRT averaged 0.75 days. The reactor pH was maintained at 2 to enhance the effectiveness of
Fenton's addition.
The last reactor (13) in series will be used as a polishing reactor for the removal of any
partially-oxidized contaminants remaining following addition of Fenton's reagent. The system
received 8.0 L/day of influent feed from R2, resulting in a HRT of 7.5 days. All operational
parameters were maintained similar to Rl, The process flow diagram (PFD) for the pilot-scale
system is presented in Figure 1.
During operation, slurry in Rl, R2, and R3 was monitored weekly for TS, volatile solids (VS)
concentrations and slurry density. Microbial enumerations of total heterotrophs and naphthalene
degraders was also conducted on the same schedule. Aqueous- and solid-phase PAH concentrations
in Rl, R2, and R3 were also monitored once per week. Volatilization of constituents was monitored
monthly in Rl off gas.
RESULTS AND DISCUSSION
4

-------
The bioslurry reactor system demonstrated 84 and 66 percent removal of PAH and CPAH.
respectively. Table 1 illustrates the reduction in concentration of all PAH compounds. Overall, the
biologically active reactors (R1 and R3) illustrated a decreasing effectiveness in PAH removal as a
function of compound molecular weight. For example, on October 19, 1994 Ri and R3 demonstrated
80 and 89 percent removal of tluorene, respectively. Removal rates were decreased to 18 and 0
percent, respectively, for the removal of benzo(a)pyrene on the same date. R2, however,
demonstrated greater than 94 percent removal of betwc(a)pyrene on the same date.
The TS distribution in all reactors was maintained consistently at 40 percent. The pH in Rl,
R2, and R3 averaged approximately 6.5, 2.0, and 6.5, respectively.
Total heterotrophic counts in Rl and R3 ranged from 10* to ICF colony forming units/millilitei
slurry (CFU/mL). Despite severe conditions maintained in R2, microbial enumerations measured
greater than 10* CFU/mL.
CONCLUSIONS AND RECOMMENDATIONS
The demonstration illustrated the potential effectiveness of combined bioslurry treatment and
chemical oxidation for the treatment of PAH-impacted soils. Continuing operation of the reactors to
effectively increase tit© removal efficiencies demonstrated during the first two months of operation
will be pursued over the ne*t four months.
