INVESTIGATION OF CHROMIFEROUS GALVANIC WASTES TREATMENT BY REACTANT AND FLOTATION METHOD COMBINATION
Abstract
The treatment efficiency of the galvanic wastes from chromium VI ions is investigated by the combined scheme including the reagent deposition of chromium in the form of Cr(OH)3 and flotation precipitation. The model experiment results and its approbation on the industrial sewage have shown that the control of the basic process conditions (pH, collecting agent, flotation treatment method) permits to reach the 98–99% level of treating water from chrome.
