| Summary: | 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. |
