Economics of a commercial slurry-phase biological treatment process
- OHM Remediation Services Corp., Findlay, OH (United States)
Slurry-phase bioremediation is an engineered process for treating contaminated soils or sludges in a slurry of water at 10 to 40% solids. Slurry-phase treatment relies on the mobilization of contaminants to the aqueous phase, where they are susceptible to microbial degradation. The mobilization or dissolution step can be the result of either microbial or physical/chemical action. Operating parameters are maintained to provide optimal conditions for biological treatment of the contaminants. OHM Remediation Services Corp. has completed the full-scale slurry-phase biological treatment of 10,500 yd{sup 3} of Resource Conservation and Recovery Act-K001 wastes at the Southeastern Wood Preserving Superfund site in Canton, Mississippi. The polycyclic aromatic hydrocarbon (PAH) concentrations in the untreated material ranged from 8,000 mg/kg to 12,000 mg/kg dry-weight. A 95% reduction in total PAH concentration was achieved following treatment.
