Abstract

The performance of natural coagulant made from tapioca starch (TS) on real partially stabilized leachate from Matang landfill was investigated. The percentage removals of suspended solid (SS), colour, chemical oxygen demand (COD) and ammonia under the influence of pH and dose by using coagulation-flocculation were recorded. The results revealed that the optimum values of pH and dose were 4 and 2.5 g/L Fe, respectively. At the optimum condition, 12%, 54.7% and 13.2% of SS, colour, and ammonia removals were achieved using TS. TS as a coagulant was able to remove SS, colour and ammonia from partially stabilized leachate. However, the removals obtained using TS were not as good as those obtained using the chemical coagulant
