Characteristics of shallow air flotation technology
. Effective water depth of the pool.
. The residence time of water entering the equipment pool is.
.Large water purification capacity, that is, low surface load.
. Low installation and maintenance costs and easy to clean.
.The degree of purification is high, and the suspended solids removal rate reaches above %.
.The design and structure are ingenious, the dissolved air efficiency is as high as %, and the volume is only one third of the general dissolved air system.
. Small footprint, light unit load, all steel components are assembled, no operating room is required, the equipment is installed overhead, and equipment with large processing capacity can be combined in multiple groups.
The main structure of shallow air flotation
The shallow air flotation device integrates flocculation, air flotation, skimming, sedimentation and mud scraping. The overall shape is cylindrical, the structure is compact, and the pool body is shallow. The main body of the device consists of five parts: the pool body, the rotating water distribution mechanism, the dissolved air release mechanism, the frame mechanism, the water collection mechanism, etc. The water inlet, water outlet and scum discharge outlet are all concentrated in the central area of the pool body. The water distribution mechanism, water collection mechanism, and dissolved air release mechanism are all closely connected with the frame and rotate around the center of the pool body. This device provides a complete set of equipment assembly and control system, which combines centralized control and decentralized control to achieve the best operating status of the equipment.
The main working principle of shallow air flotation
Air flotation separation technology means that air and water are dissolved into water to the maximum extent under certain pressure conditions, striving to be in a saturated state, and then the formed The pressure-dissolved air water is released through decompression, producing a large number of fine bubbles, which fully contact the suspended floc in the water, causing the suspended floc in the water to adhere to the micro bubbles, float to the surface of the water with the bubbles, form scum, and scrape off scum, thereby purifying water quality.
The high-efficiency shallow air flotation device developed by our company is an advanced rapid air flotation system. Based on the traditional air flotation theory, it successfully uses the shallow layer theory and zero-speed principle. Through careful design , integrating flocculation, air flotation, skimming, sedimentation and mud scraping, it is an efficient equipment for water purification treatment.
