Analysis of the functions of air flotation equipment and air flotation devices

An air flotation machine is a device that uses small or tiny bubbles to bring impurities in the medium to the surface. This air flotation device can be used for some tiny particles in the water body whose specific gravity is close to that of water and which are difficult to sink or float due to their own weight. At present, in terms of water supply and drainage, most of the pretreated water quality is light suspended particles, except for some raw water bodies with more sand and sewage with heavy mechanical impurities. For this raw water, if the traditional sedimentation method is used, the effect will be very poor, especially under low temperature conditions in winter, due to the deterioration of coagulation and hydraulic conditions, the treatment effect is more difficult to guarantee. It is conceivable that if flocs that are difficult to settle are forced to sink, it will be half the effort with half the effort. It is better to take advantage of the situation and artificially introduce air bubbles into the water body to make them adhere to the flocs, thus greatly reducing the overall density of the flocs. , and use the rising speed of the bubbles to force them to float, thereby achieving rapid solid-liquid separation. In this sense, the emergence of air flotation technology is a revolution in gravity sedimentation method, which opens up a new field of solid and liquid separation technology.
