Abstract

Wastewater generated from batik making industry contains organics dyes. Dyes are listed in the Environment Quality Act 1974 as schedule waste. Thus, it is imperative to treatthe wastewater. In this project, Fenton reaction is used to treatthe wastewater from the batik making factory. Initial analysis was done for the wastewater and the characteristics of the wastewater were identified before proceeding with the experimental procedure. Two characteristics of waste water was monitored which are the Chemical Oxygen Demand (COD) and the color changes. The COD reading was taken by using HACH method 8000. The COD reading was measured inmg/L COD and the color was measured in term of its appearance and changes. For the reaction, two parameters were fixed which are the pH and the temperature. pH is fixed at 5, whereas the temperature was fixed at 30°C. Fenton reaction used two types of chemicals, which are FeS04 and H202. The chemicals are the variable parameters in these experiments because we vary the doses of the reagent. The chemicals were mixed to a blended reagent according to the ratio needed. The efficiency of the treatment is determined by varying the ratio of Fe: H202. The decreasing value of the COD and diminished color was monitored to see the process efficiency. Comparison of the efficiency was also determined between exposing the treatment process to radiation oflight and keeping it in dark environment. Under light source radiation experiment is called photo-Fenton experiment, meanwhile for dark environment experiment is called Fenton experiment. It was found that the ratio of 1: 25 of photo-Fenton gives the best efficiency. Exposing the process to lightshowed betterprocess efficiency.
