The principle of operation is as follows. Wastewater with hexavalent chromium goes into the mixing tank, where acid concentration is equalized and more acid is added. After that the wastewater goes into the AVS, simultaneously mixed with ferrous sulphate or sodium bisulfate. The flow meter adjusts the flow rate. After chromium recovery the waste water flows into the second AVS with lime milk, forming …
