Abstract

Industrial Microbiology Laboratory of Chemical Engineering Department of Diponegoro University periodically produces organic wastewater with 2000-6000 mg/L of CODMn, which is discarded without any processing. This study aims to treat wastewater in order to reduce the organic content, by using biochemical process; aerobic and anaerobic activated sludge process. The spesific purpose of this research was to determine the effect of degradation time on the reduction of CODMn of wastewater on aerobic and anaerobic treatment process, investigate the effect of MLSS concentration on reduction of CODMn on wastewater, and also find out the efficiency of CODMn reduction of wastewater in aerobic and anaerobic treatment processes. This research is consisted of two processes: activated sludge seeding and aerobic/anaerobic wastewater treatment. The free variables used are MLSS of 1000 mg/L and 4000 mg/L. If the wastewater of Industrial Microbiology Laboratory is treated aerobically with 4000 mg/L MLSS could reduce the CODMn concentrations by 56% within 7 hours, following the modeling equation of .While if it is treated anaerobicall with 4000 mg/L MLSS could reduce the CODMn concentrations by 90,9% within 10 days, following the modeling equation of ,with constant CODMn up to 34th hour. In 4000 mg/L MLSS, the CODMn reduction is greater than in 1000 mg/L MLSS. The aerobic activated sludge process is more suited to treat the wastewater of Industrial Microbiology Laboratory, with CODMn reduction 56% within 7 hours for 4000 mg/L MLSS.
