Product information

Working Process
The air will be send by air compressor into air tank, then take in air dissolvedtank by jet flow device, the air will be force to dissolve into water under0.35Mpa pressure and forming dissolved air water, then send to air flotation
tank.Under the circumstance of sudden release, the air dissolved in water will bedissolve out and form vast microbubble group, which will be fully contact theflocculating suspended matter in sewage, the suspended matter was sent bypump and flocculation after adding medicine, the ascending microbubblegroup will adsorb in the flocculated suspended matter, made its densityreduce and floated to water surface, thus reach the purpose of removing SSand CODcr etc.

Product features
1.Low voltage operation, the dissolved gas efficiency is as high as 99%, release
rate as high as 99%.
2.Tiny bubbles and suspended particles of efficient adsorption, improve the SS
remove effect.
3.Dissolved gas water dissolving efficiency 80-100%, than traditional dissolved
gas floating high efficiency three times.

Typical Working Process of DAF System

A Dissolved Air Flotation (DAF) system is widely used in industrial wastewater treatment to remove suspended solids, oil, grease, and other pollutants. It uses chemical dosing and microbubbles to separate impurities from water, improving water quality for further treatment or discharge.

Step 1: Wastewater Inlet

Wastewater enters the DAF system. Screening and equalization help remove large particles and balance water quality and flow.

Step 2: Chemical Dosing

Coagulants are added to help small suspended particles combine into larger particles.

Step 3: Flocculation

Flocculants are added to form larger flocs, making solids and oil easier to remove.

Step 4: Air Dissolution

Air is dissolved into recycled water under pressure and released to form fine microbubbles.

Step 5: Flotation Separation

Microbubbles attach to suspended solids, oil, and grease, bringing them to the water surface for separation.

Step 6: Sludge Removal

A mechanical scraper collects floating sludge and transfers it for further treatment or dewatering.

Step 7: Treated Water Discharge

The treated water flows out of the DAF tank for discharge or further treatment, such as MBBR, MBR, or filtration.
