Which is a good dissolved air flotation machine

Working principle of air flotation equipment:

1. The dissolved air flotation machine is equipped with a pump that draws in air while sucking in water. The pump is pressurized and mixed, with high gas-liquid dissolution efficiency and fine bubbles ≤ 30um.

2. The dissolved air flotation machine operates at low pressure, with a dissolved air efficiency of up to 99% and a release rate of up to 99%.

3. The efficient adsorption of microbubbles and suspended particles improves the removal efficiency of SS.

4. The dissolution efficiency of dissolved air and water is 80-100%, which is three times higher than that of traditional dissolved air flotation.

5. The pressure capacity curve is flat, easy to achieve automatic control, easy to operate and maintain, and has low noise.

6. In the process combination of complex and difficult wastewater treatment, air flotation treatment is accompanied by the phenomenon of attached aeration, which reduces surface activity and organic concentration, greatly reduces oxygen consumption, promotes further purification of wastewater, and provides favorable water quality for lower level treatment.

1、 Application of air flotation machine

Air flotation technology has been widely used in water supply, drainage, and wastewater treatment in recent years. It can effectively remove light suspended solids that are difficult to precipitate in wastewater.

2、 Characteristics of air flotation machine

1. Large processing capacity, high efficiency, and small footprint.

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

3. It can eliminate sludge swelling.

4. Aeration into the water during air flotation has a significant effect on removing surfactants and odors from the water. At the same time, aeration increases dissolved oxygen in the water, providing favorable conditions for subsequent treatment.

5. For water sources with low temperature, low turbidity, and high algae content, air flotation can be used to obtain them Good results.

3、 Working principle of air flotation machine:

After the chemical addition reaction, the sewage enters the mixing zone of air flotation and comes into contact with the released dissolved air water, causing the flocs to adhere to fine bubbles before entering the air flotation zone. Under the action of buoyancy, flocs float towards the water surface to form floating scum. The clear water in the lower layer flows through the collector to the clear water tank, and a part of it is refluxed for use as dissolved air. The remaining clear water flows out through the overflow port. After the floating slag on the surface of the air flotation tank accumulates to a certain thickness, it is scraped into the sludge tank of the air flotation machine by a scraper and discharged.
