In coagulation-flocculation process, the M. oleifera seeds after oil extraction (MOAE) are an effective coagulant with the removal of 95% suspended solids and 52.2% reduction in the chemical oxygen demand (COD). The combination of MOAE with flocculant (NALCO 7751), the suspended solids removal increased to 99.3% and COD reduction was 52.5%. The coagulation-flocculation process at the temperature of 30 • C resulted in better suspended solids removal and COD reduction compared to the temperature of 40, 55 and 70 • C. The MOAE combined with flocculant (NALCO 7751) reduced the sludge volume index (SVI) to 210 mL/g with higher recovery of dry mass of sludge (87.25%) and water (50.3%).
