Sichuan dissolved air flotation equipment:

The dissolved air flotation machine adopts a new and efficient dissolved air equipment - microbubble generator, which replaces traditional air introduction equipment to dissolve air into water. Several inclined tube groups are installed in the air flotation area, including a box body, a scraper, and a spiral discharge machine, to form a complete air flotation water purification device. In theory, the treatment effect of air flotation is not directly related to the residence time, but only to the air flotation area. If the air flotation zone at water depth H is reduced to water depth H/10, the air flotation distance and residence time will be reduced by 10 times, which is the famous "shallow pool theory". The purpose of adding inclined tubes to the air flotation zone is to increase the air flotation area, greatly reduce the Reynolds coefficient, avoid air flotation in turbulent flow, create a good laminar flow state, and achieve the effect of shallow air flotation.

Similarly, when the density of suspended solids is greater than 1, the installation of inclined pipe groups will result in shallow pool sedimentation, allowing sedimentation to occur under turbulent conditions. Pollutant substances with larger particle size and higher specific gravity that are difficult to float will concentrate in the mud collection area, achieving the goal of water purification.
