Abstract :In this paper, the treatment of real hospital wastewater insert ignore into journalissuearticles values(HWW); by electrocoagulation process insert ignore into journalissuearticles values(EC);, which is one of the electrochemical treatment methods, has been evaluated. In the EC process, aluminum insert ignore into journalissuearticles values(Al); and iron insert ignore into journalissuearticles values(Fe); plates as anode and cathode are used. Experimental studies were conducted at 5, 10, 20, 30 voltage insert ignore into journalissuearticles values(V); and 5, 10, 20, 30, 45 minutes insert ignore into journalissuearticles values(min); exposure times. pH, temperature, and conductivity were monitored. COD and phenol removal were evaluated. As a result of experimental studies, Al and Fe electrodes were effective in the treatment of HWW with EC. The highest COD removal efficiency was 93% at 30V 10 min and 95% at 30V 5 min for Al and Fe electrode, respectively. The highest phenol removal efficiency is 97% at 10V 10 min and 97% at 10V 5 min for Al and Fe electrode. When all parameters are evaluated, optimum electro kinetic conditions for treatment of HWW was obtained for 10V 5 min by the Fe electrode.
