Product description

Rectangular dissolved air flotation is a solid-liquid separation equipment widely used in the sewage treatment industry. It can effectively remove suspended solids, oils and adhesives in wastewater. It is one of the key equipment for early treatment. Rectangular dissolved air flotation removes hard-to-settle floating flocs. It has the characteristics of large capacity, high efficiency, small footprint and wide application. Widely used in petroleum, chemical, printing and dyeing, papermaking, oil refining, leather, steel, machining, starch, food and other wastewater.

Working principle

The dissolved gas tank can generate dissolved gas, which is then released into the water to be treated through a release device. It will form tiny bubbles of 20-40um, and these tiny bubbles will combine with the suspended matter in the wastewater, making the proportion of these suspended matter smaller than that of water, and gradually float to the surface to form scum. There is a scraper system on the surface, these scum will be scraped into the sludge tank, and the water will enter the cleaning tank from the lower part of the overflow tank.

Feature

1. These tiny bubbles have a good air flotation effect.

2. During operation, the low consumption of polymer makes the cost quite low.

3. Strictly control the operation of the equipment through the control system, it is easy to control the water quality and quantity.
