A air flotation machine uses small bubbles or tiny bubbles to make the impurities in the medium float out of the surface of the surface machine. The air floatation device can be used for the weight of some of the water body, which is close to the water, and its self weight is difficult to sink or float.
At present, in the water supply and drainage area, most of the water quality to be treated is light suspended particles, except for some raw water with more sand and heavier sewage. Such as lakes, reservoirs and rivers in the algae; colloidal impurities of plant residues and small particles; dye printing and dyeing industry; short fiber papermaking, chemical fiber industry; oil and organic solvent refining and chemical industry of droplets; heavy metal electroplating and pickling wastewater from sub electrocoating wastewater and so on; all; is the proportion of light particles is very close to the water. For these raw water, if the traditional precipitation method is used, the effect will be very poor. Especially under low temperature in winter, the treatment effect is more difficult due to the poor coagulation and hydraulic conditions. You can imagine, it is difficult to precipitate flocs, insist on the sink, is bound to be more effective, rather than artificially to import in the light of its general trend, water bubbles, the adhesion to the floc particles, thereby greatly reducing the overall density of flocs, and by the bubble rise velocity, forced to float, in order to achieve solid-liquid separation fast. In this sense, the emergence of air floatation technology is a revolution to the gravitational settlement method, which has opened up a new field of solid and liquid separation technology.
