Industrial wastewaters purification using the negatively charged with calculated dispersiveness of hydrogen bubbles and special electroflotator construction in the process of electroflotation

Michael Shoikhedbrod

Abstract


The main problem in the all existing electroflotation methods of cleaning is the salinity of the space near cathode in the process of electroflotation that leads to formation of the salts sediments on the cathode that strongly cover cathode’s surface that may result of the total curtailment of the process of electroflotation. The other problem is that as anode is used the dense grid from the wire of the defined thickness, which increases the current density, but sharply reduces the transmittance of electrolysis bubbles through it and, therefore, a quantity these bubbles that stimulate the intensification of the process of flotation. During the time, salt can close the grid and lock the output of the bubbles through the grid at all. To another deficiency of the process can be attributed improperly use of gas bubbles generated during the process of electroflotation. The paper presents the use of a new developed method and constructed electroflotator for industrial wastewaters purification using the negatively charged with calculated dispersiveness of hydrogen bubbles and special electroflotator construction in the process of electroflotation.
