Hardness, COD and turbidity removals from produced water by electrocoagulation pretreatment prior to Reverse Osmosis membranes
Abstract
This study refined the hardness removal (together with chemical oxygen demand (COD) and turbidity) from the produced water by a pilot-scale electrocoagulation (EC) system to mitigate the scaling and fouling of Reverse Osmosis (RO) membranes. In preliminary studies, effects of initial pH, current density and electrolysis time on pollutant removal were investigated. Response surface method (RSM) was employed further to evaluate …
