Abstract
Four batches of potato-processing wastewater were collected every two weeks. After sedimentation for 1 h and subsequent decanting, the supernatant had a 5-day biochemical oxygen demand (BOD) ranging from 620 to 1743 mg/l and total suspended solids ranging from 0.31 to 0.49 mg/ml. Thermophilic aerobic digestion (55°C, 0.6l air/min) decreased the BOD and total suspended solids of the supernatant by 98% and 75%, respectively, in 96 h.
