Membrane technology is one of the alternative solutions to overcome industrial waste-water treatment developed nowadays. The addition of PAC (Powdered Activated Carbon) in the activated sludge using Submerged Membrane Adsorption Hybrid Bio-reactor (SMAHBR) is expected to increase the organic material removal. The purpose of this study was to determine the performance of submerged membrane bio-reactor and activated carbon adsorption capacity of organic materials in waste-water. This study used SIER (Surabaya Industrial Estate Rungkut – Surabaya, Indonesia) waste as activated sludge operated at Mixed Liquor Suspended Solid (MLSS) concentrations of 8000 and 15000 mg/l, and Chemical Oxygen Demand (COD) concentrations of 1500, 2500 mg/l, Sludge Retention Time (SRT) of 10;20; and 30 days and activated carbon variables of 0%; 2.5%; 5%; 7.5%; 10%. The results showed that the fouling potential occurred at high MLSS where the COD removal occurred at PAC addition of 10% reaching 91.86%. High Soluble Microbial Product (SMP) accumulation (± 10 mg/l) occurred in short SRT and high MLSS concentration. PAC addition resulted in decreased microorganisms in the reactor and better effluent of SMAHBR, as a result, the performance of the submerged membrane bio-reactor would be restored.
