Electroflotation Treatment of Industrial Wastewater in a Specially Designed Electroflotator Powered by a Solar Panel

Abstract

Currently, the anode in existing electroflotators is a dense mesh with small cells, which causes salt deposits to form on its surface during the electrolysis of waste water. In another case, the salt deposits completely cover the cells, which stops the electroflotation process by preventing the passage of electrolytic hydrogen bubbles through them. The use of an anode in the form of a dense mesh with small cells in electroflotators, on the one hand, increases the density of direct current flowing in industrial wastewater during electroflotation of industrial wastewater, and therefore increases the formation of microdispersed electrolytic hydrogen bubbles, which contribute to the successful electroflotation of industrial wastewater. On the other hand, the use of an anode in the form of a dense mesh with small cells in electroflotators sharply reduces the passage through this mesh of electrolytic hydrogen bubbles, formed during electroflotation of industrial wastewater, which sharply slows down electroflotation process. When the author devised electroflotation treatment for industrial wastewater in a specially built electroflotator, powered by a solar panel, this issue was resolved. The article presents a developed method of electroflotation treatment of industrial wastewater in a specially designed electroflotator, powered by a solar panel (solar cell), which includes an electrolysis base and uses negatively charged electrolytic hydrogen bubbles with a calculated dispersion, which release microscopic particles from wastewater in the process of wastewater treatment by floating up in the wastewater of the created by them strong complexes: negatively charged microdispersed electrolytic hydrogen bubbles + microscopic particles of wastewater from industrial wastewater in the process of an elementary act of flotation.
