In the process of using the dissolved air flotation equipment, there will be two air intake methods, the air intake before the pump and the air intake after the pump. The equipment is mainly led by a
1. Shallow air flotation In the initial stage of biofilm cultivation, a small-load water intake method is adopted, so that the surface of the packing layer should be gradually covered by membrane slud
When the dissolved air flotation equipment is in use, the dissolved air system will generate a large number of fine bubbles in the water, so that the air can be attached to the suspended particles in
The partially treated wastewater of the dissolved air flotation equipment passes through the dissolved air pump, and the dissolved air flotation equipment sucks in air and mixes it in the return water
Shallow air flotation water collection must ensure the balance of water in and out, so that the water level of the air flotation tank can be guaranteed to be normal. Generally, the water collecting pi
The effective water depth of shallow air flotation is 400~500mm. The hydraulic retention time in the pool (3~5min). The purification capacity is large, that is, the surface load is high. Shallow air f
1. The smaller the bubble radius, the greater the additional pressure inside the bubble, and the more and more intense the collision probability of the air molecules in the bubble to the bubble film.
1. The air flotation machine should ensure that the water level does not submerge the packing layer and affect the effect of dissolved air; it should not be lower than 0.6m to prevent a large amount o
Dissolved air flotation machine installation: 1. Before the equipment is installed, be sure to tamp the foundation. And use concrete cement mortar pad height 100-150mm. It can also be installed overhe
1. Sewage flow The influence of the sewage flow rate on the treatment effect cannot be ignored. When the dissolved air flotation machine is running, it is necessary to ensure that the water distributi
