Purification of industrial wastewater using a photoelectroflotation process powered by solar energy
Abstract: The main problem of all existing electroflotation methods of wastewater treatment is salinization of the near-anode space during electroflotation, which leads to the formation of salt deposits on the anode, which strongly cover the anode surface, which can lead to a complete stop of the electroflotation process. The anode, used by electroflotation devices has a dense grid of small cells, which, on the one hand, increases the current density, but, …
