Electrochemical degradation of a real silk textile wastewater using iron electrodes
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 6
Abstract
The electrochemical degradation of a raw real silk textile wastewater was carried out using iron electrodes in bipolar arrangement to remove chemical oxygen demand (COD), color and to reclaim clean water. Batch studies with four plate iron electrodes were identified as an optimal operating condition. 70-88% COD removal efficiency was achieved from its initial value of 1270 mg/L. The presence of chloride increased COD degradation. Iron electrode showed good settling and filterability. Water quality improved considerably after electrochemical coagulation (ECC) treatment achieving reduction in other water quality parameters viz., hardness, alkalinity, TS and chlorides.
