HS series gas dissolved air floating device

Product introduction
    Pressure gas dissolved air flotation, it is under the condition of the air in the pressurized dissolved in water, and then by rapid depressurisation supersaturated air complete air flotation is released in the form of tiny bubbles.The basic process has fully dissolved air flow, partly dissolved air flow and reflow pressurized dissolved air flow 3 kinds.Depending on the bubble precipitate of pressure, dissolved air flotation and can be divided into: true air float and pressurized dissolved air flotation.The former is creating negative pressure condition into the air to complete floating in the water; Which is under the condition of the pressurized air into the water, rapid depressurisation release, complete air flotation separation bubble.
    Pressure dissolved air flotation (pressurized dissolved air flotation) is a highly efficient material processing technology, is widely applied to remove emulsified oil, vegetable oil, all kinds of oily wastewater (G) O, paint, rubber paint, leather suspended solids (TSS) and COD in waste water, the pulp fiber in papermaking wastewater recycling, printing and dyeing, bleaching, wool spinning in the wastewater in addition to COD, BOD and SS, chromaticity, such as electroplating heavy metal ions in waste water.Pressure dissolved air flotation is widely used in the sludge concentration, water reuse, food processing, etc.
Air flotation is micro bubbles generated by the air floated dissolved air equipment and adhesion on the sewage flocculated grain, which makes flocculant grain of mandatory buoyancy, realize the solid-liquid separation of a physical process.
