The shallow air flotation mainly adopts the patented technology of high frequency common rail jet cutting, which produces strong centrifugal force by high-speed rotation and micron air integrated injection system, so that the concentration of dissolved air and water reaches the theoretical value in only 3 seconds without concentration shaving, thus guaranteeing the manufacture of large-scale micro-bubbles, as well as the dynamic factor. The cost of electricity consumption is reduced by a large margin.

Shallow air flotation makes wastewater enter into the air flotation tank through water distribution system. In use, the wastewater entering the air flotation tank achieves zero velocity in the water distribution area and the air flotation area through air flotation water distribution system and stepless speed regulation device. The floc and pollutants bridged by micro-bubble adsorption play an important role in buoyancy and zero velocity. The solid-liquid separation is carried out rapidly.

The clear water area of shallow air floatation tank is separated and floated, and the scum pollutants are removed by screwing spoon with screw, flowing to the sludge barrel, flowing to the scum tank under gravity, and the clean water separated from the lower layer flows to the clear water tank through the clear water extraction tank tube under the rotary bucket.

Sludge in shallow air flotation slag pool is pumped to sludge dewatering system by sludge pump. The filtrate is discharged from ditch to catchment pool. Dry sludge is transported for landfill or comprehensive treatment. Sewage flows from ditch to catchment pool to make water quality and quantity balanced.www.khnwatertreatment.com
