Impact of Chemical Waste Discharge on BOD Removal in Sewerage Treatment Plant

The performance system of the aeration tank and clarifier was studied to enhance the performance ofUniversity Technology Petronas (UTP) sewage treatment plant (STP). A pilot plant with feeder tank, aeration tank and clarifier was used to simulate UTP's STP. The parameters evaluated in the s...
