Vortex Concave Air Flotation Machine

The vortex concave air flotation machine adopts the principle of combining mechanical aeration, sludge, and chemical flocculation to treat various types of sewage with different water quality. It is an ideal physical and chemical equipment. The vortex concave air flotation machine directly injects the "micro-bubbles" into the sewage without dissolving air in advance and then distributes the "micro-bubbles" evenly in the sewage through the air diffuser impeller, so there will be no blockage during the entire operation. The vortex concave air flotation machine is mainly composed of a box body, an aerator, a mud scraping system, etc., and does not require equipment such as pressure dissolved air, air compressor, and circulating pump.

System structure and principle of vortex concave air flotation machine

The vortex concave air flotation machine is a system specially designed to remove grease, colloid, and suspended solids in industrial and municipal sewage.

The pretreated sewage flows into a small aeration section equipped with a vortex concave aerator. During the rising process of the sewage, the micro-bubbles generated by the aerator in the aeration section are fully mixed, and the aerator sends the air on the water surface through the exhaust pipe. Transfer to underwater.

Remove suspended solids, grease, and various colloids in various industrial and municipal sewage, used in electroplating, chemical industry, papermaking, etc.

Advantage:

1. Save investment

There is no pressure vessel, air machine, circulating pump, or other equipment in the vortex concave air flotation, so the equipment investment is low

2. Small footprint

Reduce land investment

3. Low operating cost

The vortex concave air flotation is easy to operate, and there is no complicated equipment at all, so the manual operation and maintenance workload is very small, reducing labor costs and maintenance costs.

4. Significant processing effect

The removal rate of petroleum and suspended solids exceeds 80%. The removal rate of BOD and COD can reach more than 60%.
