Abstract

Activated sludge system is a biological wastewater treatment applied for domestics and industries that could eliminate carbon, nitrogen, and phosphor. An activated sludge system needs to have the right design in order to achieve high quality effluents. Methods used in this research are Conventional, MLE and UCT. Conventional method use the confignration of one reactor aerobic, MLE use an anoxic-aerobic· configuration, and UCT use an anaerobic-anoxic-aerobic configuration. Result of the simulation for F 1M showed that sludge concentration will increase when FIM increase. For 10wFIMvalue 0.15 mg COD mg VSS dail will result on sludge concentration (MX.) 954 kg TSS and excess sludge (MEt) 27.73 kg/day. For high FIM value 0.95 mg COD mg VSS dail will result on MXt 150 kg and MEt 50.82 kg TSS/day. The MLE and UCT configuration could achieved the nitrogen effluent of 10 mgIL on FIM value 0.2-0.35 mg COD mgVSS-1 day-I. Conventional configuration result on effluent nitrogen concentration of20 mgIL on FIM value 2 mg COD mgVSS-1 dail. UCT methods result in higher Phosphor elimination, which value is 0.87 mgIL on FIM value 0.4 mg COD mg VSS-I day-l MLE and Conventional methods result on effluent phosphor 31 mgIL on FIM value of2 mg COD mg VSS-I hari-I.
