At present, in terms of water supply and drainage, the pre-treatment water quality of electrolytic air flotation machines mainly consists of lightweight suspended particles, except for some raw water bodies with high sand content and sewage with heavy mechanical impurities. For example, algae in lakes, reservoirs, and some rivers; Plant residues and small colloidal impurities; Dye particles in the printing and dyeing industry; Short fibers in the papermaking and chemical fiber industries; Droplets of petroleum and organic solvents in the refining and chemical industries; Heavy metal ions in electroplating and pickling wastewater; Electrophoretic paint wastewater, etc; They are all lightweight particles with a density very close to water. For these raw waters, if traditional sedimentation methods are used, the effect will inevitably be poor, especially under low temperature conditions in winter. Due to the deterioration of coagulation and hydraulic conditions, the treatment effect is even more difficult to guarantee. It can be imagined that if the difficult to precipitate flocs are forced to sink, it will be twice the result with half the effort. It is better to take advantage of the situation and artificially introduce bubbles into the water to adhere to the flocs, thereby significantly reducing the overall density of the flocs. With the speed of the bubbles rising, they can be forcibly floated up to achieve rapid solid-liquid separation. In this sense, the emergence of air flotation technology is a revolution in gravity settling method, which has opened up a new field of solid liquid separation technology.

Electrolytic air flotation machine is a device that removes solid suspended solids, oils, and various gelatinous substances from various industrial and municipal wastewater. This equipment is widely used for the treatment of industrial wastewater and municipal sewage in refining, chemical, brewing, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing, etc.
