This study reveals that the treatment of tannery effluent samples by electro flotation. In this system, the various parameters like effect of pH, current density, COD, total solids, addition of surfactant and flocculent were investigated. It was found that maximum degradation was at the current density of 0.14A/cm2 and at a pH of 6.0. Under the same experimental conditions the removal efficiency of chemical oxygen demand (COD) and total solids were found to be approximately 66.3% and 80% respectively. The current density was the most significant factor in the suspended solids elimination by the addition of surfactant and flocculent concentration. The addition of surfactant increases the COD removal and it also enhances the total solids removal. The flocculent also enhanced electro flotation and this technique was found to be effective in removing total solids and reducing COD from tannery effluents. These results intend an important role of these parameters in electrochemical process for removing tannery effluents.
