| Abstract |
A lack of information on applicable removal technologies for total chemical oxygen demand (TCOD) prevented promulgation of best available technology economically achievable (BAT) limitations and new source performance standards (NSPS) for TCOD for pharmaceutical manufacturing plants in 1983 (EPA/440/1-83/084). One technology that was evaluated was powdered activated carbon (PAC) addition to an activated sludge system (PACT*). A viscous floating mass of mixed liquor solids (VFMLS) developed in the PACT units and resulted in premature termination of the study. The purposes of the study were to: (1) attempt to find the cause of the formation of the VFMLS; (2) generate additional research data for TCOD removal from pharmaceutical wastewater using the PACT process; (3) evaluate the efficiency of PACT in removing specific organics; (4) evaluate the effectiveness of PACT in reducing effluent aquatic toxicity and (5) evaluate the use of a selector to improve the settleability of the mixed liquor. One control unit, two PACT units and a unit equipped with a series of selector basins for improving the settling characteristics of the mixed liquor suspended solids were operated. |
