What is "shallow air flotation"It is a main method of dissolved air flotation.The device integrates coagulation, air flotation, slag skimming, sedimentation and mud scraping.The whole is cylindrical with compact structure and shallow pool.
The main body of the device is composed of five parts: pool body, rotating water distribution mechanism, dissolved air release mechanism, frame mechanism, water collection mechanism and so on.The water inlet, the water outlet and the scum discharge outlet are all concentrated in the central area of the pool. The water distribution mechanism, the water collection mechanism, and the dissolved air release mechanism are all closely connected to the frame and rotate around the center of the pool.This device provides a complete set of equipment assembly and control system. The shallow air flotation combines centralized control and decentralized control to make the equipment reach a better operating state.Shallow air flotation is one of the key items in the water treatment process, solid-liquid separation technology and equipment.For the removal of small suspended particles whose specific gravity is close to water, shallow air flotation is one of the more effective methods.
1.The effective water depth is400-500mm.
2.Hydraulic retention time in the pool(3-5min).
3.The purification capacity is large, that is, the surface load is high.
4.Small footprint, light unit load, all prefabricated components are assembled, no operation room is required, equipment is installed overhead, and multi-layer combination is also possible.
5.Installation and maintenance costs are low and easy to clean.
6.The degree of purification is high, and the removal rate of suspended solids is over 90%.
7.The structure is ingenious, the dissolved gas efficiency is as high as 90%, and the volume is only one-fifth of the general dissolved gas system.
