Advection flow dissolved air flotation machine

Dissolved air flotation technology has been widely used in water supply and drainage and wastewater treatment in recent years, and it can effectively remove light floating flocs which are difficult to precipitate in wastewater. Large processing capacity,

Structural features:

The main body of the device is a rectangular steel structure. The main components are composed of dissolved air pump, air compressor, dissolved gas tank, rectangular box, air floating system, scraping system and so on.
1. The dissolved gas tank produces fine bubbles with a particle size of 20-40um, and the adherent floc is firm, which can achieve a good air floatation effect;
2. The amount of flocculant used is small and the cost is reduced;
3. The operation rules are easy to master, the water quality and quantity are easy to control, and the management is simple.
4. There is a backwash system, and the release device is not easy to block.

working principle:

The dissolved gas tank generates dissolved gas water, and the dissolved gas water is released to the water to be treated by a release pressure. The air dissolved in the water is released from the water to form tiny fine bubbles of 20-40 um, and the microbubbles are combined with the suspended matter in the sewage, so that the specific gravity of the suspended matter is less than water, and gradually floats to the surface to form scum. A scraper system is provided on the water surface to scrape the scum into the sludge tank. Clear water enters the clear water pool from the lower part through the overflow trough.
Use range:
1. It is used to remove solid suspended solids, oil and various gels in sewage, such as sewage treatment in industrial enterprises such as petrochemical, coal mining, paper making, printing and dyeing, slaughtering and brewing;
2. For the recovery of useful substances, such as: the collection of fine fibers in paper white water.
