Description:
The effluent from dye manufacturing industry is more difficult to be treated than laboratory synthesized wastewater according to high variability of composition and color intensity. Thus, this study aimed to propose the method for remedying industrial effluent by UV/H"2O"2 process in a recirculated batch reactor system while considering the effects on hydrogen peroxide dosage, UV power and wastewater intensity for the removal of color and COD. From the experimental results, it was feasibly treated that the distinguished removal of color and COD by increasing the hydrogen peroxide dosage and UV power, but not by the strong intensity of industrial effluent. Therefore, UV/H"2O"2 process of the developed reactor was a positively superior treatment or pre-treatment for dye manufacturing plant effluent to comply the regulated requirements.
