Abstract

A raw domestic wastewater (DWW) was treated using a modified electrocoagulation and conventional electrocoagulation (EC) experimentally. The EC process was modified by providing the plate connected by earth as earthen system and compared it with the conventional system under same operational conditions.
The initial medium strength COD ranged from 500 to 700 mg/l was used. A bench scale electrocoagulation unit has been operated under batch operational conditions along nine months. The electrocoagulation unit has been consisted of transparent basin containing iron and aluminum electrodes which are connected to a power supply unit. The system was operated under different operational conditions by applying voltages 9, 18, and 27 volts. The treatment retention time ranged from 30 to 60 min. and inter change the polarity of plates periodically every 10 min. 
The experimental results confirm that, earthen system plays a vital role to get fast reliable removal efficiency compared with the conventional system. The modified earthen system achieved removal of 97% for COD with retention time of 30 minutes and volts of 9 V (six plates) instead of 60 min in case of conventional system under same operational conditions. The removal efficiency was controlled accurately by changing the number of charged plates, retention time, and volt values. The modified system save the consumption material electrodes and energy and reduced retention time to 30 min. compared with the conventional electrocoagulation system
