Recycled ferric chloride (RFC) from Printed Circuit Board (PCB) waste sludge was used as a conditioning agent for dewatering of municipal sewage sludge. A conventional method of capillary suction time (CST) was used to measure dewaterability of the sludge. The result was compared with other conditioners which are commercial ferric chloride, ferric sulphate, and alum. Result shows that RFC of volume 0.8mL yields the best CST value compared to other conditioners. The supernatant quality of all sludge samples were measured by measuring COD and TSS. Result shows that RFC with volume 0.8mL gives the best COD and TSS value. Chemical precipitation was conducted on sludge with RFC floes for copper removal at pH9 and the result obtained was 99.76% copper removal efficiency.
