Abstract
Economic feasibility has been studied for removal of copper from acid mine drainage wastewater by ion exchange. Ion exchange method has been used for removal of copper from industrial wastewaters. Experiments were conducted using packed bed column. The present study were carried out for solutions with concentrations of 100 mg/lit to 200 mg/lit and pH values of 3 to 6, using Indion 730, strong acid cation exchange resin. Under the present operating conditions considered, the strong acid type resin was found to bring down initial copper content by almost 46-56 % and at pH 5, 60% of copper removal for 200 mg/lit of initial concentration was found. The techno economic feasibility was then studied and the rate of return found to be 21% which is economically viable.
