The performance of combined treatment processes, namely coagulation and
Sequential Batch Reactor (SBR) to treat effluent from food processing industry
was evaluated. The experimental study was conducted in a batch mode using
pilot-scale reactor. The parameters used in assessing the treatment system were
BOD" COD and SS. The optimum amount of chemicals for the coagulation
process ranges from 20 mgIL to 80 mgIL for coagulant and 60 mgIL to 220 mgIL
for polymer while the optimum pH ranges from 5.5 to 7.0. The compliance of
Standard A of the Environmental Quality Act was met using the combined
process with SBR retention time of 6 hours.
