Working principle
The dissolving air tank can produce dissolving gas which later be released to the water waiting to be treated through the release device. It will form tiny bubbles of 20-40um and those tiny bubbles will combine with suspended solids in the waste water to make the proportion of these suspended solids smaller than water and gradually float to the surface to form scums. With a scraper system on the surface, these scums will be scraped into the sludge pool while the water will enter the clean pond from the lower part of the overflow trough.
