Abstract
This research studied the reduction of pollution load from textile wastewater through COD and color removal using electrocoagulation technique. Experiments were carried out on a laboratory scale using mono-polar two aluminum plate as electrode material with total 32.68 cm2 of reaction area. The electrical potential was 12-24 volts. Inter-electrode spacing was kept at 4 cm. The effects of relevant wastewater characteristics such as pH, and important process variables such as applied voltage and operating time on the chemical oxygen demand (COD) and color removal efficiency has been explored. Maximum removal of COD (86.5%) and color (93.4%) was observed at initial pH of 5, the cell time operation was 60 minutes. These results indicate that electrocoagulation process using aluminum electrodes could be effective for removal of COD and color from textile wastewater.
