Function of air flotation machine

The main function of air floatation machine is to realize solid-liquid separation or liquid-liquid separation, which is commonly used in sewage treatment and also widely used in microalgae collection. In short, the air flotation machine is a relatively advanced sewage pretreatment equipment on the market at present, which can "float" the pollutants through the role of "gas" under suitable conditions, and then quickly remove the pollutants in the water, so as to purify the water quality.

The air floater is one of the sewage treatment equipment that is widely used at present. It can produce a large number of tiny bubbles in the water and make the air adhere to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state of less density than water. It is a water treatment equipment that uses the buoyancy principle to make it float on the water surface, thus achieving solid-liquid separation. There are three types of air floaters: dissolved air, shallow layer and concavity. At present, it has been applied in water supply, industrial wastewater and urban sewage treatment. The advantages of air flotation machine are that its solid-liquid separation equipment has the characteristics of low investment, small floor area, high degree of automation, convenient operation and management, simple operation and maintenance, and is deeply loved by market users.

Air floatation equipment can be effectively used for the concentration of activated sludge. Some air floatation equipment take removing suspended impurities in sewage as the main purpose, or as the pretreatment of secondary biological treatment, to ensure the relative stability of biological treatment influent water quality, or as the advanced treatment of secondary biological treatment after secondary biological treatment, to ensure that the quality of discharged effluent meets the requirements of relevant standards.

There are three types of air floaters: dissolved air floaters, concave air floaters and shallow air floaters. Dissolved air flotation machine is subdivided into horizontal flow type and vertical flow type. It is widely used in the treatment of water supply, industrial wastewater and urban sewage, aquaculture and slaughterhouse sewage. As a solid-liquid separation equipment, it has the characteristics of low investment, small floor area, high degree of automation and convenient operation and management.
