High efficiency shallow air floatation machine air floatation equipment

High efficiency shallow air floatation machine

High efficiency shallow air floatation machine is a machine that USES small bubbles or tiny bubbles to make the impurities in the medium surface.In the process of water supply and drainage treatment, solid and liquid separation technology and its equipment is one of the key processes.Air flotation is the most effective method for the removal of fine suspended particles whose specific gravity is close to that of water.

The equipment has been successfully designed using the "shallow pool theory" and the "zero speed" principle, which integrates flocculation, air flotation, slag skimming, precipitation and mud scraping. It is an efficient and energy-saving water purification equipment.Widely used in water supply and drainage treatment engineering.

The main purpose

First, it is applied to the water treatment of the water plant for the water source of the lake to remove algae and reduce turbidity.

Second, it is applied to industrial sewage treatment engineering, such as petrochemical, papermaking, textile, printing and dyeing, electroplating, leather making, food industry and other fields.

Third, it is applied to the recovery of useful substances in sewage, such as paper making, pulp water fiber recovery.

Principle and structure

With dissolved air system into a large amount of air to water, formation of dissolved air water, into the water to be processed, decompression after their release in the water to form a large number of tiny air bubbles, bubbles in the impurities in the water flocculation mutual adhesion formation density less than water floating body, quickly emerged, after scraping the slag skimming device to complete the solid and liquid two phase separation, the purified water quality.

The main body is composed of pool body, slag skimming device, working bridge and walking device, water and gas distributing device, water collecting device and electricity collecting device.

The characteristics of

1. Adopt "shallow pool theory" and "zero speed theory" design, high efficiency, energy saving, small size, convenient installation.

2. Short residence time (3 ~ 5min) high coating load rate (9.6 ~ 12 m2·h).

3, the use of high-speed motor drag, strong adaptability, good process conditions.

4. The method of distributing water completely separated from the dissolved air water and the raw water is equipped with a special releaser, which has a good treatment effect. The ss removal rate is as high as over 90%, and the slagging rate can reach 3-4%.

5. High degree of automation, convenient management and reliable operation.
