Recovery of Heavy Metals from Chrome - Plating Rinse Wastewater by Reverse Osmosis

Recovery of Heavy Metals from Chrome - Plating Rinse Wastewater by Reverse Osmosis

Wastewater produced by industries contains harmful and toxic metals which danger the receiving water. Chrome – plating rinse water which contains chromium is very toxic to the environment. Reverse osmosis is used with the tubular module B1 membrane to reduce the chromium, manganese, lead and copper...

Chrome – plating rinse water which contains chromium is very toxic to the environment. Reverse osmosis is used with the tubular module B1 membrane to reduce the chromium, manganese, lead and copper to a reasonable level which is less harmful. Chromium (Cr) is reduced by 87.9% while Lead (Pb) is reduced by 94.3% followed by Manganese (Mn) by 85.7% and Copper (Cu) by 91.9%. the fluxrate increase with tranmembrane pressure from 43 l/m2.
