With fast industrial developmens, human life has become more materially civilized. On the contrary a great deal of waste water were brought by the industrial manufacturing. In the mean time, large quantity of household waste were also resulted from our daily life. All of these has affected the living quality and damaged the environmental ecology. HEBEI CHUANYUAN HYDRAULIC ENGINEERING CO., LTD has been making every endeavour in developing the waste water processing equipment. In addition to sewage pump, waster handling pumps, sludge dehydration system, the company also developed submersible aerator and surface aerators for higher processing rate of BOD and COD in the processes of waste water. These aerators have been widely used in domestic and overseas waste water processing plants.

Feature(Refer to Fig.A)
Type AR submersible aerator utilizes the rotation of the impeller coupled directly to motor to create a centrifugal force, which make local low pressure suck in water. Meanwhile the entrance of the impeller result in vacuum to draw air from atmosphere. Water and air mix in the chamber of Aeration Housing. The air-water-mixture current is discharge speedily by the centrifugal force.
Due to the water spurting extremely strong, make the fluid create convection and circulation effectively. Moreover the air becomes tiny bubbles. On the one hand the bubbles rise slowly, on the other hand the atmosphere oxygen is dissolved in water. Because the bubbles are tiny and numberless their surface area is large, it makes the oxygen transfer rate of uni8t efficieney higher than other type of aerator.
