COMPARISON OF DECOLORIZATION OF INDUSTRIAL WASTEWATER BY H2O2 AND SOLAR OR ULTRAVIOLET RADIATION

Abstract

The degradation of the dye in coating metal manufacturing wastewater was investigated in laboratoryscale experiments, using photooxidation techniques in the effect of pH; contact time and H2O2 concentration were investigated. The efficiency of photooxidation were compared using hydrogen peroxide (30%) as a bleaching reagent, solar and ultraviolet radiation, common glass borosilicate, quartz tubes, and no solid catalysts. Thus, this appears aimed to propose the method for remedying industrial effluent by UV/H2O2, solar/ H2O2, UV and solar without H2O2.
