Industrial Wastewaters Purifier

Abstract

The main problem in all existing electroflotators for wastewater treatment is the salinization of the space near the cathode during electroflotation, which leads to the formation of salt deposits on the cathode, which heavily cover the cathode surface, which can lead to a complete coagulation of the process. electroflotation cleaning. Another problem is that a dense wire grid of a certain thickness is used as the anode, which increases the current density, but sharply reduces the passage of electrolysis bubbles through it and, consequently, the number of these bubbles, which stimulate an increase of the current of flotation process. Over time, salt can close the grid and generally block the bubbles transmission through the grid. Other disadvantages of the process can be attributed to improper use of gas bubbles formed during the electroflotation process. The article presents a developed industrial wastewater purifier for industrial wastewater treatment, using negatively charged hydrogen bubbles with a calculated dispersion and having a special design that permits to eliminate all the disadvantages of existing electroflotators due to the shape of the purifier and the design of its electrolytic base.
