A variety of waste water treatment processes are reported. Destruction of free and organically bound cyanides by alkaline hydrolysis in a pipeline reactor was studied. A bench-scale pilot system combining coagulation, sedimentation, and ultrafiltration to study treatment of animal wastewater was developed. A pilot limestone contactor was evaluated for its ability to treat a low pH, low alkalinity surface water supply for corrosion control, and as a conditioning step for flocculation. Experiments were conducted with a falling film reactor to determine the potential of freeze concentration to treat municipal wastewater for reuse. The effects of reductants and alkali on the sludge quantity from chromium(VI) wastes and the leachability and physical properties of solidified chromium sludge were investigated. Development and experience with a pilot-scale surfactant washing-flushing system to remove polychlorinated biphenyls (PCBs) from contaminated soils was reported.
