Abstract

 Even though Reverse Osmosis (RO) is one  of the greatest prominent and effective techniques for the  waste water treatment, but it also generates large amount  of concentrated brine known as RO reject. The present  work aimed to achieve maximum efficiency as well as  optimal conditions for the treatments of petro-chemical RO  reject by electro-oxidation process using graphite  electrodes. The Response of the Surface Methodology  under Central Composites Design was utilized to examine  the effects of various independent parameters likes reaction time, pH, current density as well as electrode  distance on the removal efficiency. The maximum total  dissolved solid (TDS) removal was obtained 51.16% at  optimum situation. 1st as well as 2nd orders kinetic model were fitted to described the finest kinetic model for TDS  removal. The effectiveness of electro-oxidation therapy in  removing TDS was studied. During EO treatment, TDS  removal was found to be substantially influenced by  solution reaction time, pH, current density, and electrode  gap.
