Dissolved Air Flotation System

Daf dissolved air flotation and ace air charged entrainment combined into one attached and entrained air for higher separation efficiencies.

Dissolved air flotation system.

Pewe has specialized in manufacturing premium quality dissolved air flotation equipment since entering the water treatment marketplace back in 2007. The released air forms tiny bubbles which adhere to the suspended matter. Our dissolved air flotation solutions provide high quality high capacity and efficient clarification. Extensive applications daf systems can be applied as a pretreatment to meet a municipality s specific limits for oil grease or suspended solids or to remove contaminants that would negatively impact an industrial biological wastewater.

Air is dissolved in the treated water by the addition of compressed air to a pressurized stream of recycled effluent. Daf systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including. Upgradable to a full its integrated treatment system including upgraded control panel chemical feed pumps polymer make down system flocculation tubes pre wired and pretested as a complete wastewater treatment system. In the dissolved air flotation system a liquid stream saturated with pressurized air is added to the dissolved air flotation unit where it is mixed with the incoming feed.

As the pressure returns to the atmosphere the dissolved air comes out of the liquid forming fine bubbles bringing fine particles with them. The dissolved air flotation system has proven to be very effective in industrial wastewater pretreatment and has been used in various applications within water wastewater and desalination applications to maximize removal of suspended solids and colloidal particles and substances a flocculator with chemical dosing can be added in front of the daf. Dissolved air flotation daf is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. Conceptually the daf process is simple tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water but designing a daf system for a real world application isn t quite as simple.

Dissolved air flotation systems effectively remove tss fog and other pollutants from wastewater. This ensures the polluted water is. Hei manufactured dissolved air flotation systems daf efficiently separate total suspended solids tss and fats oils and grease fog particles from industrial effluents. Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams.
