Dissolved Air Flotation System, DAF Wastewater Treatment Equipment
If you are looking for a machine to treat sewage with a large amount of suspended matter or sewage with high oil content, such as to treat micro-polymers such as algae in water, then the dissolved air flotation system produced by BETTER EPT is your best choice. The scum produced after treatment can be automatically discharged, and the solid matter in the discharged scum is up to 30-100g/L.

Details
The chain and sprocket wheel of the scraper device
The chain and sprocket wheel of the sludge scraper of the dissolved air flotation system produced by BETTER EPT are made of nylon material, which gives the chain and sprocket wheel good mechanical strength, wear resistance and shock absorption. It can also effectively separate the solid and the liquid in the scrum area.
Releaser
The releaser is one of the most important components of the dissolved air flotation system, the function of which is to release bubbles in the sewage and with the bubbles adhering to the pollutants, the pollutants in the sewage will float to the surface under the reaction of buoyancy. The releaser produced by BETTER EPT is made of stainless steel material, so it’s more corrosion resistant. And with the countless micro bubbles released by the releaser, the removal rate of suspended matters is effectively improved.

Characteristics
The reflux ratio of the dissolved air flotation system is high and the quality of the effluent is good.
The dissolved air flotation system will aerate the water to remove the surfactant and odor in the sewage effectively during the treatment process. Meanwhile, the aeration increases dissolved oxygen in the water, which provides favorable conditions for the subsequent treatment.
Working principle
Raw water
Dissolved air water
Scum discharge
Outlet water
By releasing a large number of microbubbles in the sewage and with the bubbles adhering to the pollutants, the pollutants in the sewage will float to the surface under the reaction of buoyancy. And after the sludge is discharged by float removal system, the solid and the liquid are effectively separated.
