The treatability of wastewaters produced during oil shale retorting

OSTI ID:5196091

Pilot-scale field treatability studies on real-time oil shale wastewaters from Occidential in-situ MIS retorts demonstrated that retort water had high concentrations of ammonia, TKN, alkalinity, dissolved organics, phenols, sulfide, and TDS; and gas condensate had high concentrations of ammonia, TKN, dissolved organics, alkalinity, phenols, and sulfide. Steam stripping was effective in removing ammonia and alkalinity from the retort water. Steam stripping, activated sludge treatment - both conventional and PAC, sand filtration, and GAC adsorption were effective in removing ammonia, alkalinity, TKN, nitrate, soluble COD, soluble BOD/sub 5/, DOC, phenols, sulfide, and TSS from the gas condensate. Pollutant removal efficiencies across individual treatment units for retort water and gas condensate treatment schemes are presented.
