DAF dissolved air flotation machine

1. Product overview of dissolved air flotation machine:

The dissolved air flotation machine designed by our company is mainly used for solid-liquid or liquid-liquid separation. A large number of fine bubbles are generated in the water through the dissolved gas and release system, so that they adhere to the solid or liquid particles in the wastewater with a density close to the water, resulting in a state where the overall density is less than that of water, and relying on buoyancy to make it rise to the water surface, so as to achieve the purpose of solid-liquid or liquid-liquid separation.

2. Characteristics of dissolved air flotation machine:

1. Large processing capacity, high efficiency and small land occupation.

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

3. It can eliminate sludge expansion.

4. Aeration to the water during air flotation has obvious effect on removing surfactants and odors in the water, and at the same time, due to the increase of dissolved oxygen in the water, it provides favorable conditions for subsequent treatment.

5. For water sources with low temperature, low turbidity and many algae, the air flotation method can achieve obvious results.

3. The working principle of dissolved air flotation machine:

1. Dissolved air flotation machine is mainly used for solid-liquid or liquid-liquid separation. A large number of fine bubbles are generated in the water through the dissolved gas and release system, so that they adhere to the solid or liquid particles in the wastewater with a density close to the water, resulting in a state where the overall density is less than that of water, and relying on buoyancy to make it rise to the water surface, so as to achieve the purpose of solid-liquid or liquid-liquid separation.

2. A large amount of air is dissolved in water to form dissolved water, which is used as a working medium to be released quickly by sudden depressurization through the releaser, resulting in a large number of fine bubbles adhering to the "alum flower" of the wastewater after the coagulation reaction to make the floc float, so as to quickly remove the pollutant substances in the water to achieve the purpose of water purification.

Dissolved air flotation machine is widely used in: textile sewage, printing and dyeing sewage, electroplating sewage, food factory sewage, slaughtering sewage, meat processing plant sewage, tannery sewage, etc.
