Abstract

The suitability and effectiveness of recycled ferrous sulphate (RFS) extracted from groundwater treatment sludge to improve settleability of municipal sludge and treatment leachate was investigated in this study. The groundwater sludge was taken from Chicha Water Treatment Plant, Kelantan. Since the groundwater sludge contains non-hazardous metal like iron and manganese, it cannot be discharge plainly without proper treatment because if happen, it may lead to the pollution of surface water and ground water system and thus, create the environmental problem. The study involved the experiment to use the RFS as a coagulant material for settleability improvement in sewage municipal sludge's treatment and the result is compared to the other commercial coagulants which are alum (Al2 (804)3), ferrous sulphate (FeS04), and ferric chloride (FeCl3). Apart from settleability, the study also focused on the RFS efficiency on removal of Chemical Oxygen Demand (COD), Color, and Total Suspended Solid (TSS) in the leachate treatment. As a result, RFS proved to be a better coagulant for sludge settleability which recorded 5.15 cm/min and performance increased by 115%, compared to alum 4.8 cm/min (100% efficiency), FeCl3 3.875 cm/min (62% efficiency), and FeS04 3.75 cm/min (56% efficiency). In leachate treatment, FeCU is the best coagulant in COD removal since it recorded 68% efficiency, followed by RFS (67% efficiency), alum (36% efficiency), and FeS04 (20% efficiency). For Color parameter, alum is the best coagulant since it recorded 90% removal, followed by RFS (88%), FeCl3 (64%), and FeS04 (27%).
