Abstract

ABSTRACT In this study, will be known ability of UASB reactors (Upflow Anaerobic Sludge Blanket) in a laboratory scale in processing the mixture of domestic waste water (grey water and black water) by varying the upflow velocity and influent concentration. Influent concentrations used are of three kinds, namely the concentrations of low, medium and high. The parameters examined were BOD5 (Biological Oxygen Demand), COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid). Maximum values obtained of COD removal efficiency is 69%, whereas the maximum BOD5 removal efficiency is 76%, and the maximum TSS removal efficiency is 72%. The higher the concentration of waste water, the greater the concentration of BOD5, COD, and TSS that can be removed by the microorganisms in the UASB reactor. Overall, the reactor with slow upflow velocity is allowing time for microorganisms to decompose the substrate in the wastewater, so that the removal efficiency obtained is higher. However, the results of treatment using the UASB reactor was not yet meet the quality standard (KepmenLH. No. 112 , 2003 and Perda Jateng No. 10, 2004), thus requiring further processing to be discharged into water bodies. Keywords : mixture domestic wastewater, UASB, concentration, upflow velocity
