What are the advantages of the shallow air float compared with the traditional air float?

Shallow gas floating machine in the process of use is a kind of inlet air floating system, to a certain extent, the success of using the principle of the theory of zero speed and shallow pool design, coagulation, gas floating, skimming, precipitation, scraping mud at an organic whole, is a kind of high efficiency and energy saving of water purification equipment.

What are the advantages of the shallow air float compared with the traditional air float?

1. In general the conventional flotation device, the device of the pool depth of 2.5 m or so, this is mainly because the device is stationary, and water body is in motion, when making use of the water enters the experience from the reaction chamber and effective contact area will produce the redistribution of the change of flow and flow velocity, namely transform water into uniform flow upwards, which requires a certain time and height to complete the change, its height is generally not less than 1.5 m.

Shallow gas float will effectively using the principle of the zero speed, to a certain extent, can effectively achieve the equipment is in motion, the water is stationary, eliminate the disturbance of due to water effect on the separation of suspended particles and water, reduce the demand for highly, the other in traditional air floating device, the hard to avoid flocculant with mud or drowned in the bottom, to prevent out of the bottom mud, outlet pipe is generally 300 mm high.

2. In the traditional air flotation device, the residence time of the water body in the process of operation is generally controlled at 10-20min; In the shallow air flotation device, the residence time is only 4 ~ 6min. In the shallow air flotation device, the mud scraper is set up at the bottom of the pool, so it is not necessary to set the overhanging section. Through the above analysis, the effective water depth of the shallow gas floating device is 400 ~ 500mm.

3. In the traditional air flotation device, the dissolved air system is equipped with the dissolved gas tank. If the actual volume of the gas tank is calculated, its hydraulic retention time is 2 ~ 4min. In the shallow air flotation device, the dissolved air system is used to remove the filling, and the volume utilization rate of the dissolved air pipe is 100%, and its hydraulic retention time is only 10 ~ 15s.

4. In traditional air flotation device, in the process of operating the slag scraper when making use of need to remove the scum layer on a regular basis, not according to the float of scum selective clean-up time, thus not only has large disturbance to the water body, and the moisture content of scum is larger.http://www.shallowairfloatation.com/
