Abstract :
Effluent samples were collected from electroplating industry at kot lakhopat Lahore. The samples were physically and chemically analyzed for different parameter and metals concentrations. The concentration of all metals including chromium, canduim, nickel manganese and iron were than threshold limit. Chromium is environmentally hazadousb and carcinogenic. The electroplating effluent with high chromium concentration has been treted 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 0.1 0mg/L Cr (VI) in filtrate.
