Dissolved Air Flotation System

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 system. Hei manufactured dissolved air flotation systems daf efficiently separate total suspended solids tss and fats oils and grease fog particles from industrial effluents. Daf systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including. 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. This ensures the polluted water is.

We hold us patents 8431022 and 9962631 for the design of our daf water treatment equipment as well as 21 registered trademarks pewe is proud to offer our clients the largest array of dissolved air flotation systems on the market today. 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. Air is dissolved in the treated water by the addition of compressed air to a pressurized stream of recycled effluent. Our dissolved air flotation solutions provide high quality high capacity and efficient clarification.

Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. 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. Dissolved air flotation systems.

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. 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.
