The new method of purification of the industrial waste waters
Abstract: The main problem in the all existing electrofloatation methods of cleaning is the increase of the alkalization space near the cathode that leads to formation of the salts sediments on the cathode as a result of passing of the electric current through the water environment. The salts so tightly cover cathode’s surface that can cause the total curtailment of the process of electrofloatation. This can be explained by the fact …
