Design criteria for in-situ and on-site renovation of an industrial sludge lagoon
- Rutgers Univ., Piscataway, NJ (USA)
The case history of design and implementation of a remediation strategy for a hazardous waste disposal site is described. Over several decades, sludges from chemical manufacturing were disposed of in an unlined surface impoundment. The 4.1 acre site contains approximately 23,000 m{sup 3} of sludge. Laboratory experiments were conducted to evaluate forced extraction of the sludges, aerobic mixed microbial (secondary) treatment and soil-based microbial treatment of leachate and sludge extracts. Exhaustive extraction of TOC from the sludges, with dilute aqueous sodium hydroxide, was possible. Treatment of leachate and sludge extracts with a soil-based microbial treatment process achieved TOC reductions in excess of 95%. A pilot plant to demonstrate these processes for clean-up of the lagoon was designed, constructed and operated for 140 days. In-situ sludge extraction followed by on-site soil-based microbial treatment was employed. Results confirmed laboratory findings. Design criteria for the full-scale renovation of the lagoon have been developed. Preliminary design estimates indicate the complete lagoon renovation will require about five years of process operation at a total cost of approximately $3,000,000.
