Abstract

Multi Soil Layering (MSL) system is a method of wastewater treatment that increase the soils function to purify wastewater. In the construction of MSL, soils mixed with the charcoal and then filled into the box of size 50x14x50 cm in layers structured like brick pattern. The aims of this research are to determine the concentration of BOD and COD on textile industrial wastewater before and after the process by MSL method. It also determines the optimal loading rate of wastewater on the MSL system, and then it can determine the efficiency of MSL system on reducing the concentration of BOD and COD on textile industrial wastewater. The method which used in this research is an experimental method. The wastewater on the MSL system is loaded on the loading rate variety: 160, 320, 480, 640, and 800 L m-2 day-1. The efficiency of MSL system to removing BOD and COD on textile industrial wastewater are determined on optimal loading rate. The research gave result that MSL method could remove BOD and COD on textile industrial wastewater on the optimal loading rate 320 L m-2 day-1. The efficiency of MSL system in removing BOD and COD on textile industrial wastewater are 96.52 and 80.87% respectively. This indicated that the method MSL serve the purpose of effective alternative method in processing of liquid waste textile industry.

Abstract

Activated and impregnated TiO2 zeolite systems to reduce TSS, BOD, and COD of tofu industrial wastewater in Cilongok Villages had been developed. Activated and impregnated zeolite systems were expected to be able to reduce the concentration of TSS, BOD, and COD. Thus, the research was aimed to know the ability of zeolite systems to reduce the concentration of TSS, BOD, and COD of tofu industrial wastewater. The research used five difference loading rates of tofu industrial wastewater which were 160, 240, 320, 400, and 480 L m-2 day-1. The most effective loading rate was determined by analyzing the concentration of TSS, BOD, and COD before and after processing using zeolite systems. The reduced concentration of TSS, BOD, and COD was determined by filling the activated and impregnated zeolite with industrial wastewater for 24 hours continuously in 30 days. Sampling was done in every 5 days with loading rate of 320 L m-2 day-1. The results indicated that zeolite systems could reduce the concentration of TSS, BOD, and COD of tofu industrial wastewater. The optimum loading rate to reduce the concentration of TSS, BOD, and COD was 320 L m-2 day-1. The efficiency of acid activated zeolite system in reducing the concentration of TSS, BOD, and COD were 83.348%, 91.899%, and 90.700%, respectively. The efficiency of base activated zeolite system in reducing the concentration of TSS, BOD, and COD were 84.380%, 93.711%, and 91.928%, respectively. The efficiency of impregnated zeolite system in reducing the concentration of TSS, BOD, and COD were 82.410%, 90.711%, and 89.917%, respectively.
