The shallow air flotation machine is cylindrical in shape, compact in structure and shallow in pool. The main body of the device consists of five parts: pool body, rotating water distribution mechanism, dissolved gas release mechanism, frame mechanism, water catchment mechanism, etc. Inlet, outlet and scum outlet are all concentrated in the central area of the pool. Water distribution mechanism, catchment mechanism and dissolved gas release mechanism are closely connected with the frame and rotate around the center of the pool.

Shallow air flotation machine provides complete sets of equipment assembly and control system, through the combination of centralized control and decentralized control, so that the equipment can achieve good operation. Solid-liquid separation technology and equipment is one of the key projects in water treatment process. The equipment is one of the effective methods for removal of micro suspended particles whose specific gravity is close to water.

The technological process of shallow air flotation machine:

1. Sewage flows from ditch to catchment basin to make water quality and quantity balanced.

2. Then the sewage pump is lifted to the air floatation tank.

3. Adding PAC and PAM to the inlet of sewage, the sewage is fully mixed through the mixing pipe at the bottom of the air floatation tank, and then mixed with some micro-bubbles with positive charge generated by the dissolved air system, so that the micro-bubbles can be absorbed with pollutants in flocculants and wastewater, and bridged into the air floatation water system.

4. Water distribution system is used to make the wastewater enter the air floatation tank, and water distribution system and stepless speed regulating device are used to make the wastewater enter the tank reach zero speed in the water distribution area and the air floatation area. www.khnwatertreatment.com
