A full-scale anaerobic filter system has been used to treat industrial wastewater having flow rates and CODs ranging from 400 to 1500 m3/d and 10 000 to 30 000 mg/L, respectively. The reactors were of the hybrid configuration and contained corrugated, modular, cross flow plastic media having a specific surface of 98 m2/m3. Facilities were included to store and feed nutrients and trace minerals, and equalization was provided to attenuate variations in waste strength. After seeding and subsequent removal of specific waste streams that were found to be inhibitory to anaerobic microorganisms, the COD re moval efficiency stabilized at about 80%. After 1 year, the reactors were converted to series operation as a first cycle in a two-stage, cyclic mode. During the second year of operation, the COD removal performance stabilized at 93 to 95%. No sludge was wasted from the reactors during 600 days of operation. Res. J. Water Pollut. Control Fed., 63,153 ( 1991 ).
