Anaerobic biological treatment of in-situ retort water

“…13) and others at Battelle are conducting studies of steam stripping, anaerobic and aerobic biological treatment, and carbon adsorption. These studies, to date, have indicated that steam stripping is viable and that biological treatment of some waters may be feasible if powdered activated carbon is added to the reactor and if long cell residence times are used, Steam stripping of Geokinetics retort water (initial NH3 = 3,000 mg/1) removed 90 percent of the ammonia with recycle of condensate at a boiloff rate of 4.5 percent and over 99 percent of the ammonia without recycle at a boiloff rate of 5.3 percent.…”
