Abstract

Electrocoagulation is a complex process with a multitude of mechanisms operating synergistically to remove pollutants from the water. In this paper, application of electrocoagulation using common electrode materials (aluminum and iron) to a simulated reactive distillery effluent was investigated. Based on the dynamic characteristics of batch electro coagulation, three operating stages (lag, reactive, and stabilizing) are proposed to identify the relationships among the zeta potential. The experimental results showed that the removal efficiency was better, reaching to about 62%, when applying activated charcoal adsorption before treating with the electrocoagulation cell. The study focuses on the effect of electrolysis time, current density, initial pH, inter-electrode distance, initial dye concentration and type of supporting electrolyte. In the sets of experiments the optimum condition for dcolourisation has been found out.
