UREA REMOVAL FROM WASTEWATER USING ELECTROCOAGULATION PROCESS UNDER VARIOUS OPERATING CONDITIONS

Abstract

In this research, the efficacy of electrocoagulation has been investigated as a potential treatment process for the removal of urea from synthetic and real domestic wastewaters. The purpose of this research is to evaluate the ability of the electrocoagulation process to remove urea using aluminum, titanium, copper and iron electrodes under varying operating conditions. The impact of electrode material type, electrode voltage, electrolyte type, and electrode spacing has been investigated. The maximum removal efficiencies for urea occurred after 90 min and its values were 67.85% at a 9 V for titanium, 57.76 % at 12 V for the aluminum electrode, 49.65% at a 6 V for the copper electrode and 59% at 12 V for the iron electrode. Comparative analysis of urea uptake by chemical coagulation and electrocoagulation has been conducted.
