In recent years, dissolved air flotation technology has been widely used in drainage and wastewater treatment. It can effectively remove the light flocs which are difficult to precipitate in wastewater. The processing capacity is high, the efficiency is high, the land occupation is small, and the scope of use is wide. It is widely used in petroleum, chemical industry, printing and dyeing, paper making, oil refining, leather, steel, mechanical processing, starch, food and other sewage treatment.

Scope of application:

In the field of water treatment, air floatation machines are applied in the following aspects:

1. Separation of fine suspended solids and algae from surface water.

2, recovery of useful substances in industrial waste water, such as paper pulp from waste water.

3. Replace two settling tanks to separate and concentrate sewage sludge.

Technical advantages:

1. High processing capacity, high efficiency and less land occupation.

2, the process and equipment are simple in structure, easy to use and maintain.

3. Sludge bulking can be eliminated.

4. Aeration to water during air floatation has obvious effect on removing surfactant and odor in water. At the same time, aeration increases dissolved oxygen in water, which provides favorable conditions for subsequent treatment.

5. For low temperature, low turbidity and algae laden water sources, air flotation can achieve the best results.
