Multiphase dissolved air flotation is a highly efficient water treatment technology.
The multiphase mixed dissolved air flotation system is mainly composed of a dissolved air system, a release system, and an air flotation tank. Its working principle is to dissolve air in water under a certain pressure to form dissolved air water, and then release the dissolved air water into the water to be treated under reduced pressure. At this time, the air dissolved in the water precipitates in the form of tiny bubbles. These tiny bubbles have a high specific surface area and can fully contact with pollutants such as suspended particles, oils, and organic matter in the water. Due to the buoyancy of the bubbles, the pollutants are brought to the water surface to form scum, thereby achieving solid-liquid separation or liquid-liquid separation.
This technology has many advantages. First of all, it can effectively remove suspended solids, grease, color and other pollutants in the water, significantly improving the water quality. Secondly, multi-phase mixed dissolved air flotation has high processing efficiency and fast processing speed, and can process a large amount of water in a short period of time. In addition, this technology is relatively simple to operate, stable and reliable in operation, and occupies a small area. It is suitable for the treatment of various industrial wastewater and domestic sewage, such as wastewater treatment in papermaking, printing and dyeing, food processing, petrochemical and other industries.
In practical applications, multi-phase mixed dissolved air flotation can be combined with other water treatment technologies to form a more complete water treatment process. For example, it can be combined with biological treatment technology to first remove most suspended solids and organic matter through air flotation, and then perform biological treatment to further degrade the remaining pollutants, thus improving the efficiency and effectiveness of the entire water treatment system. In short, multi-phase mixed dissolved air flotation technology has important application value and broad development prospects in the field of water treatment.
