ELECTROCOAGULATION (EC) AND ELECTROCOAGULATION/FLOTATION (ECF) PROCESSES FOR REMOVING HIGH TURBIDITY FROM SURFACE WATER USING AL AND FE ELECTRODES

on (EC) and Electrocoagulation/flotation (ECF) processes are simple and efficient in water and wastewater treatment. In recent years, many investigations have focused on the use of these processes for treating of polluted water. The purpose of this study was to investigate the efficiency of EC and ECF processes in removal of high turbidity water using different electrodes in different circumstances. In present study an electrocoagulation and electrocoagulation/ flotation reactor in a lab scale to an approximate volume of 6 liters which is equipped with four Al-AL and Fe-Fe electrodes (200 * 20 * 2 mm) was used for removing of high turbidity water. The effects of operating parameters such as type of electrodes, initial water turbidity, applied voltage (10 to 30 v), initial pH of the solution (3 to 12) and reaction times (5 to 30 minutes) were evaluated.
