Abstract
Industrial waste is the biggest contributor to river water pollution, one of which is tofu industrial waste. Tofu industrial wastewater contains a lot of high organic matter. High organic matter content will increase the BOD and COD values of the waters and will have a negative impact if not handled properly. Therefore, to remove contaminants effectively still requires more advanced technology at lower costs. This study provides an alternative that can be used to overcome these problems, namely by using Resin Immobilized Photocatalyst Technology (RIPT). This study presents the RIPT reaction kinetics with various catalysts (TiO2, ZnO), catalyst mass (10gr, 20gr, 30gr), and RIPT mass (5gr, 10gr, 15gr), and samples were taken every time 0.30,60,120,180 minutes. To determine the value of the COD removal reaction rate, it can be seen at the value of the reaction rate constant. Based on the results of the study, the best value for the reaction rate constant was obtained by varying the mass of RIPT (15gr) on each catalyst (TiO2, ZnO). While the best value for the reaction rate constant was obtained by the variation of the mass of the catalyst TiO2 30 grams and ZnO 30 grams, with the results of the reaction rate constant value of RIPT-TiO2 30 grams of 0.0101 minute-1, and RIPT-ZnO 30 grams of 0.0144 minute-1. This is due to the increasing mass of catalyst and RIPT mass which can affect the photocatalyst surface area to become larger, so that the reaction rate will also increase. The half-life value obtained in this study is that RIPT-TiO₂ takes about 69 minutes for half of COD to be degraded from its initial concentration, while RIPT-ZnO takes about 48 minutes to do the same thing. Keywords : Liquid Waste Tofu Industry, Chemical Oxygen Demand (COD), Photocatalyst, Resin, Resin Immobilized Photocatalyst Technology.
