Abstract

Anaerobic degradation of coke oven wastewater with starch as co substrate was carried out in an UASB reactor seeded with anaerobic sludge of VSS concentration 45000mg/Lobtained from anaerobic digester treating starch effluent of sago industry. The reactor was operated with synthetic starch and coke oven wastewater at various mixing ratio viz. 95/5, 90/10, 85/15, 80/20 and 75/25.The COD and phenolics (mixture of phenol and chlorophenols) removal were monitored. Removal efficiency of COD were ranging between 70 to 78% and phenolics removal efficiency ranged among 73.3 to 82%.Maximum of 82% of phenolics and 78% of COD removal efficiency were obtained at a mixing ratio of 85/15.
