Abstract
Effluent samples were collected from electroplating industry at Kot lakhpat Lahore. The samples were physically and chemically analyzed for different parameters and metals concentrations. The concentrations of all metals including chromium, cadmium, nickel, manganese and iron were higher than threshold limit. Chromium is environmentally hazardous and carcinogenic. The electroplating effluent with high Chromium concentration has been treated through chemical precipitation (CP). The treatment of chromium is pH dependent. The experiment results showed that CP process has successfully eliminated chromium from electroplating effluent. The percentage removal is 95 % chromium leaving less than 0.10mg/ L Cr (VI) in filtrate.
