Abstract

This research is undertaken to investigate various operating conditions for minimising sludge disposal and maximising chemical oxygen demand from leachate. With conventional extended aeration process the optimum removal of COD and colour were 36% and 24% respectively. In Fenton process, for optimum pH of 5 and optimum H2O2/Fe2+ molar ratio of 1.3, the dosages of H2O2 and Fe2+ were found 1000 mg/l and 1250 mg/l, respectively. Under these conditions, the achievements for optimum COD and colour removal were 80% and 97%, respectively, while a combined treatment process of aeration followed by Fenton process resulted into higher COD and colour removals.
