Dual Treatment of Milk Processing Industry Wastewater Using Electro Fenton Process Followed by Anaerobic Treatment

Milk processing industry produced in large amounts wastewater with high pH, temperature and toxic matters. These effluents can exhibit serious environmental problems and public health concerns if improperly disposed. In this present study, an attempt has been made to investigate the efficiency of combined treatment for milk processing industry wastewater. Advanced oxidation process used as primary treatment where as biological process is applied as post treatment to degrade the toxic matters. Parameters affecting the combined process on the percentage removal of turbidity and chemical oxygen (COD) demand were studied in detail. Under the optimum conditions, 93 % of turbidity and 97 % of COD were removed. These results indicated that the proposed technique could be used to degrade the maximum turbidity and chemical oxygen demand from milk processing industry wastewater.
