Abstract: The electro-coagulation and floatation method was applied for the treatment of high-salinity organic wastewater of producing synthetic resin by the lac . It was found that COD_Cr and BOD₅ removal rates were 94% and 90% respectively. In addition to its obvious effectiveness of treatment for organic compounds, the electro-coagulation and floatation method requires only simple facilities, with high resistance to impact and simple operations, without additional chemical agents and easy to realize management modernization.
