    Abstract

    Sintetic Waste water of starch contained in average COD about 12300 mg/L and BOD 10.650 mg/L respectively. Waste water treatment of starch plant using biologycal treatment and settling commonly. Problem that frequently found in the biologycal treatment is dificulty in separation of biomass and incomplete contact of waste water with microorganisme and oxygen in the system. To overcome those problem is by applying system combination with aeration perforated plate bioreactor and membrane technology. Volume of bioreactor that used is 6 liters. Membran was polysulfon hollow fiber type. Hidraulic Residence Time (HRT) was 24 hours and Cell Residence Time (CRT) was 20, 40 and 60 days. Parameter process that measured is COD, BOD, DO and pH. The result of the research were efficiency COD removal for CRT 20, 40, 60 days can remove COD 92.8, 95.4 and 97.2%. respectively. BOD of effluent was 190-510 mg/L. DO of effluent was 0.5–0.7 mg/L. DO of permeat was 1.3– 1.9 mg/L and pH 6.6 – 6.9 mg/L. Keywords : Sintetic Waste water of starch, perforated plate bioreactor, membrane
