Shallow Coagulation Skimming Sewage Dissolved Air Flotation Equipment

Efficient shallow dissolved air flotation equipment for sewage treatment


Main structure

Efficient shallow air flotation equipment combines functions of coagulation, flotation, skimming, precipitation and scraping mud together. The whole structure is compact, cylindrical with shallow pool. The main body of the device is composed of the following five parts: the tank body, rotary water- distributing bodies, dissolved air releasing mechanism, a frame mechanism and water-collecting mechanism etc. Water inlet, outlet and scum outlet are all concentrated in the central region of the tank body, water distributing bodies, water-collecting mechanism, the dissolved air releasing mechanism are all connected with the frame and rotate around the center of the tank . The device provides the complete sets of equipments and control systems, by the combination of centralized control and decentralized control, enables the device to achieve the best operating status.

Application

1st, Solid-liquid separation equipment and technology is one of the key items in the water supply process. As to the the removal of tiny suspended solid,proportion of that is close to the water, air flotation is one of the effective ways.The equipment is widely used in water treatment engineerings.

2nd, The equipment can be used to remove the algae and descend the turbid of city water supplied from lakes.

3rd, Applied to industrial wastewater treatment engineerings, such as petrochemical. textile, printing and dyeing, electroplating, tanning, food industries etc.
4th, applied to recycle useful substances in sewage, such as the fiber recovery from paper, water industries.
The main operating principle

Air flotation separation technology refers to that the air and water under the certain pressure conditions makes the air dissolving to the water to the maximum, in saturated state, and then releases the formed pressured dissolved air water through decompression to produce lots of tiny bubbles and fully contacts with suspended solid ,then the suspended flocs adhere to the bubbles raising to the surface of the water companied with the bubbles, then scums are formed and scraped, to realize the purification of water.
The efficient shallow air flotation equipment developed by our company is an advanced high-speed air-floating system, based on the traditional theory of air flotation and the successful use of the "shallow theory" and "zero" principle.Through careful design, combines coagulation, flotation, skimming, precipitation and scraping mud functions in one is the efficient equipment for water purification.
