Dairy industries have shown tremendous growth in size and number in India and other countries of the world. These industries discharge wastewater which is characterized by high chemical oxygen demand, biological oxygen demand, nutrients, and organic and inorganic contents. Such wastewaters, if discharged without proper treatment, severely pollute receiving water bodies. One of the most serious environmental problems is the existence of hazardous and toxic pollutants in wastewaters. Adsorption is considered to be one of the most promising techniques for wastewater treatment over the few decades. Attempts were made in this study to examine the efficiency of Fenton process combined with coagulation for treatment of dairy wastewater. Parameters affecting the Fenton process, such as pH, dosages of Fenton reagents and the contact time, were determined by using jar test experiments 82% of chemical oxygen demand (COD) could be removed at pH 3.0, 1000mg/L H2O2, 2041mg FeSO4 and 50 minutes contact time. The coagulation using ferrous sulfate (FeSO4) was beneficial to improve the Fenton process treated effluent in reducing the flocs settling time, enhancing turbidity and COD removal. The overall turbidity and COD reached 78%, and 85% under selected conditions, respectively. Thus this study might offer an effective way for wastewater treatment of dairy industries.
