Abstract


Synthetic dyes were commonly used in textile industries such as Jumputan fabric industries in South Sumatera. Most of these industries were categorized as a home industry without a wastewater treatment plant, so the wastewater is released directly into waterbody. In general, the wastewater contains synthetic dyes, which are harmful to the environment and human body. Therefore, the wastewater needs to be treated before its release into the environment. Reactive Red 2 (RR2) is one of important synthetic dyes usually applied for colouring textile materials such as Jumputan fabric. The RR2 was used as a pollutant model in this research. The objective of the study is to compare the removal of RR2 by using Fenton/TiO2, Fenton/UV, and Fenton/TiO2/UV methods. Furthermore, the optimum conditions obtained were applied for the treatment of wastewater from Jumputan fabric industry. As a conclusion, the highest RR2 degradation of 100% was reached by using the Fenton/TiO2/UV method after 5 minutes of reaction. It was discovered that the optimum conditions were found when using [Fe2+]/[H2O2] molar ratio of 1:80, pH of 3, and TiO2 concentration of 0.4% (w/v). However, the application of the condition to the Jumputan wastewater treatment leads to Chemical Oxygen Demand (COD) removal of 94% within 120 minutes of reaction.
