Flat-flow volumetric air flotation

Flat-flow volumetric air flotation

The dissolved air tank produces dissolved air water, which is released into the water to be treated under reduced pressure by the releaser. The air dissolved in the water is released from the water to form tiny bubbles of 20-40um. The micro bubbles are combined with the suspended solids in the sewage, so that the proportion of the suspended solids is less than that of the water, and gradually float to the surface to form scum. A scraper system is provided on the water surface to scrape the scum into the sludge pool. The clean water enters the clean water pool from the lower part through the overflow tank.

Product Introduction

The dissolved air tank produces dissolved air water, which is released into the water to be treated under reduced pressure by the releaser. The air dissolved in the water is released from the water to form tiny bubbles of 20-40um. The micro bubbles are combined with the suspended solids in the sewage, so that the proportion of the suspended solids is less than that of the water, and gradually float to the surface to form scum. A scraper system is provided on the water surface to scrape the scum into the sludge pool. The clean water enters the clean water pool from the lower part through the overflow tank.

 

Product Features

1. The main body of the equipment is rectangular steel structure.

2. The main components are composed of dissolved air pump, air compressor, dissolved air tank, rectangular box, air flotation system, mud scraping system, etc.

3. The bubbles produced by the dissolved air tank are small, the particle size is 20-40um, and the adhesion flocs are firm, which can achieve good air flotation effect;

4. Flocculant use less, lower cost;

5. The operating procedures are easy to master, the water quality and quantity are easy to control, and the management is simple.

6. With backwashing system, the releaser is not easy to block.
