Abstract

Pharmaceuticals and micro pollutions have been regularly flushing into water resources through municipal and industrial wastewater plants. This problem therefore, needs more attention. Conventional water and wastewater treatment plants couldn’t eliminate these pollutions and it needs advanced treatment, otherwise humans and animals’ health would be in danger by them. Advance oxidation processes have the ability of removal of Pharmaceuticals like Carbamazepine. And in this study, Carbamazepine removal has been examined through Electrochemical Peroxidation process at optimum pH(e.g. pH=3), also other effective operation conditions include contact time, current density, hydrogen peroxide and proportion of iron to hydrogen peroxide have been optimized through surface response method by Design Expert software. After experiments was completed, results have been analyzed and correlation coefficient of 94 percent computed, and proportion of iron to hydrogen peroxide has been identified as the most effective parameter in Carbamazepine removal. To achieve a removal more than 90%, 13 solutions have been predicted by different operation conditions. The best scenario with 98% desirability, was 67.5 minutes contact time, 26 mM hydrogen peroxide concentration, 14.75 mA current density and 0.002 proportion of iron to hydrogen peroxide.
