Anaerobic–aerobic system for beverage effluent treatment : performance evaluation and microbial community dynamics
A novel ‘anaerobic filter’ with a pulsing bio-cord bed, the anaerobic pulsed bed filter (APBF), was integrated with the aerobic sequencing batch reactor (aeSBR) to treat effluent from a beverage manufacturer. The APBF reactor achieved 61% COD and 70% BOD removal at 8 h HRT and 5.45 kg COD/m3.d OLR....
