Penyisihan BOD dan COD dari Limbah Domestik Dengan Metode Multi Soil Layering (MSL)

Abstract

Water pollution that occurs in the Cikarang Baru Housing is currently showing serious symptoms and must be treated immediately, because the river in the Cikarang Baru housing produces an unpleasant odor and has a black appearance. The cause of pollution does not only come from domestic or household waste but industrial waste. How to remove BOD and COD pollutant parameters in Domestic waste using Multi Soil Layering (MSL) in Cikarang. To determine the effect of the MSL method with decreasing BOD and COD. The Multi Soil Layering method is one of the wastewater treatment methods that utilizes soil as the main medium by enhancing it through a structure formed in a construction in the form of a layer of soil mixed with organic matter, carbon and other materials such as iron powder with a layer of rock (zeolite, perlite, and gravel) in the form of a stone arrangement. The highest pollutant removal for COD, BOD, and pH parameters was obtained at HLR 500 l/m2. days with the highest percentage of allowance of 70%. The results of the final waste concentration test in the treatment using MSL show that the variation of HLR greatly influences the removal of pollutant parameters in domestic waste. Domestic Waste Elimination with the MSL Method is able to treat domestic waste by decomposing organic substances BOD and COD simultaneously, is also capable of accepting high hydraulic loading rates (HLR) and absorption.
