Domestic Wastewater Treatment with Multi Soil Layering Method with Variations of Hydraulic Loading Rate (HLT) And Organic Materials at Anaerobic Conditions

Abstract Domestic wastewater is the largest producer of in Indonesia which comes from remnants household activities. Hazardous substances such as Biological Oxygen Demand (BOD), Chemical (COD), Total Suspended Solid (TSS), Oil and Fat contained can cause health problems for humans. In this study, domestic waste treatment was carried out using Multi Soil Layering (MSL) method. The MSL system a method that utilizes ability soil main medium several other media zeolite, gravel, charcoal, sawdust are formed multilevel brick pattern. independent variables variation mixture with (M1) charcoal (M2) also variations Hydraulic Loading Rate namely HLR 500 L/m2.day (H1), 750 L/m 2 .day (H2), 1000 (H3). characteristics include pH 6, BOD 236 mg/L, COD 514 TSS 114 8200 mg/L. results showed best removal pollutant levels average efficiency reducing BOD, COD, TSS, & levels, respectively. 86.39%, 78.29%, 86.56% 79.60%.
