The understanding of the dissolved vacuum air floatation equipment and the selection of the air floatation machine

【Summary】Air flotation equipment, in brief, is a kind of air flotation equipment, therefore, it is called the air flotation equipment. And, it has many types there are a lot of related problems. So, next, we will introduce some specific kinds, and at the same time answer the questions of the air floating equipment. So that you can learn and have a deep understanding of it.


1.The dissolved vacuum air floatation equipment of the air flotation equipment


In the air flotation equipment, the dissolved vacuum air floatation equipment, specifically speaking, is a kind of air floatation equipment that dissolves the air in the water under normal pressure or prelum, and precipitated in the negative pressure state.


The advantages of the dissolved vacuum air floatation equipment are that the formation of bubbles, the adhesion and the flotation of particles are carried out in a stable environment, so that the flocculating constituent can not be destroyed, thereby effectively reducing energy consumption. However, it does not apply to wastewater with a concentration of more than 250 - 300 mg / L. Moreover, if the wastewater is aerated under atmospheric pressure and dissolved in vacuum conditions, it can be called vacuum air flotation.

 

2.Does the air floatation machine stand for the air flotation equipment?

Whether we need to choose different air flotation equipment if the water volume is different?


The air floatation machine stands for the air flotation equipment. And the air floatation machine has different types, such as shallow highly active air flotation machine, cavitation air flotation machine, dissolved air floatation machine and so on. if the water volume is different, we need to use different air flotation equipment. If the water volume is small ,we need to use the dissolved air floatation machine. And if the water volume is large, then we need to use the shallow air flotation machine.


3.What is the specific application of the air flotation equipment in the sewage treatment? In addition, the principle of the coagulation air flotation equipment is same as the principle of flat flow air flotation?


The specific application of the air flotation equipment in the sewage treatment is the solid - liquid separation and concentration of the excess sludge in the sewage treatment process to treat the wastewater well. The principle of the coagulation air flotation equipment, and the principle of flat flow air floating is same, but has a coagulation reaction zone.
