UTILIZATION OF CANE AND SAVAGE LEATHER AS ACTIVE CARBON MEDIA IN REDUCING COD AND TSS CONCENTRATION OF TOUCH WASTE

Abstract

Abstract
Tofu industrial liquid waste contains organic compounds such as protein, carbohydrates and fats. Untreated waste can cause odor and discoloration in river water. Therefore, a research was conducted to produce a fairly simple and inexpensive technology for treating liquid waste using the absorption method. The aim of this study was to determine the effectiveness of activated carbon from cassava peels and bagasse in reducing COD and TSS concentrations in the tofu industry.
This study uses the absorption method to determine a process that occurs when a fluid (liquid or gas) is bound to a solid and finally forms a film (thin layer) on the surface of the solid. In addition, it is also to determine the waste parameters in tofu liquid.
The results showed that bagasse activated carbon could reduce the highest COD concentration by 61.38% at a particle size of 200 and a decrease in the highest TSS concentration of 52.03% for a particle size of 200 mesh. Activated carbon of cassava peels decreased the highest COD concentration by 74.74% at particle size 170 and the highest decrease in TSS concentration was 96.74% at 200 mesh particle size.
