the wastewater arrives from the chrome-plating plant, and comes from degreasing rinse, nickel rinse, and chromium rinse. The water is treated with sulfuric acid to lower pH to 2,5; sodium bisulfite is used to reduce chromium from hexavalent to trivalent. Then we add ferric cloride. Next step is add lime to increase the pH up to 11 pH.
