Abstract |
From September to December, 1984 pharmaceutical plant wastewater containing high concentrations of total chemical oxygen demand (TCOD) in the raw waste and treated effluent was treated in trailer mounted pilot plants. The biological treatment train used to treat raw wastewater consisted of three activated sludge systems operated in parallel. Powdered activated carbon (PAC) was added to two of the units in selected dosages. The third unit was used as a control. The physical-chemical treatment train studied in the treatment of pharmaceutical plant effluent consisted of chemical coagulation with alum and anionic polymer; pH adjustment with caustic (when needed); clarification; multi-media filtration and granular activated carbon (GAC) adsorption. The PAC enhanced biological treatment train as operated during the test period reduced influent TCOD concentration to well below the plant best practicable control technology currently available (BPT) TCOD level. PAC also improved the settling rate of the mixed liquor suspended solids when compared to the control. |
