✦ Synopsis

Five process unit operations were evaluated for gectiveness in treating aqwm @mnt from a hazardous waste treatment f i t y . The aqueous @mnt contained r e s i d d amounts of various organics and heavy metals. The objective of the &t test program was to produce an aqueous product which could meet requirements for discharge to a P O W , or directly to the environment, and a solid product which c d be disposed of in a Class Z hndfl. Processes evaluated included one primary, evaporative c rystdization, two secondary, activated sludge &-treatment and reverse osmosis, and two tertbry, carbon d o r p t i o n and ultraviolet perofiidation. Test results from these process operations identified several processing conjigurations whereby thefinal treated product could meet discharge criteria. Performance results of

each process unit operation are summarized and discussed.
