In the sewage treatment process, shallow air flotation, a traditional process, is in an indispensable position, especially for fine particle suspensions whose specific gravity is close to that of water, this method can better ensure the solid-liquid separation effect . Especially in the process of dissolving air, releasing air, solid-liquid separation, and purification of wastewater treatment, air flotation is more effective and useful for sideline separation technology.
Air flotation water purification technology is not only widely used abroad, but also recognized by everyone in China. In particular, the shallow air flotation device is a complete set of treatment systems such as air collection flotation, scum skimming, and mud scraping. , the purification effect is also very obvious in practical applications, and it is widely used.
In addition, the shallow air flotation machine is basically close to zero speed from the perspective of water flow speed, so the suspended solids in the water can be better statically purified, with a removal rate of over 90%, and the pool is relatively shallow, and the water depth is usually only 650mm, so floating The resistance is small and the speed is faster, which is what we usually call faster skimming. Moreover, the main body of the air flotation machine has a compact structure. Whether it is the water distribution, water collection mechanism or air dissolution mechanism, they are all connected in a centralized manner, which can better work around the purification pool.
In addition, there is an effective shallow air flotation machine, which can complete the purification work more effectively and energy-saving, and is very easy to install. And it is equipped with a special releaser, so the water and waste water filled with dissolved air are distributed in separate ways, which can achieve better treatment effects. In addition, the air flotation machine has a high degree of automation and is more convenient to use.
