ROLE OF ELECTRO-DIALYSIS AND ELECTRO-DIALYSIS CUM ADSORPTION FOR CHROMIUM (VI) REDUCTIOND. SIVAKUMAR, D. SHANKAR, A.N. KANDASWAMY AND M. AMMAIAPPAN
In the present study, chromium (VI) was removed using the method called electro-dialysis, and electro-dialysis cum adsorption methods. The experimental investigations have been carried out by using electro-dialysis and electro-dialysis cum adsorption methods for different temperatures and different agitation speeds against different pH. The study compared the results of wastewater treated with electro dialysis method with electro-dialysis cum adsorption method. The validation tests proved that the selected method is having reproducing capacity for removing Cr(VI) from any type of Cr(VI) contaminated wastewater. Finally, this study concluded that the maximum removal of chromium (VI) from tannery industrial wastewater was found with the combination of electrodialysis cum adsorption method than electro-dialysis method alone.
