3. Dissolved Air Floatation (DAF) Dissolved Air Flotation (DAF) unit is a solid/ liquid separator machine which injects microfine air bubbles that attach to suspended solids so that the solids float to the surface. DAF is suitable to treat water or wastewater containing oil, grease or particles that float easily on the water.

But it is related to the air flotation area. If the air flotation area of the water depth H is reduced to the water depth H / 10, the air flotation distance and the residence time will be reduced by 10 times. This is the famous "shallow pool theory". The air floatation machine is specially equipped with a new type of container device, which can ...

A dissolved-air flotation machine dissolves air into the water to be treated by passing the water through a pressurizing pump, introducing air, and holding the air-water mixture at high pressure long enough for the water to become saturated with air at the high pressure. Typical pressures are 20-75 psig.

Flotation as a water treatment technology has been widely used in sewage treatment and water purification works, the equipment used in: 1. Remove the algae and dirt in the water from river or lake, purify it to become drinkable water or landscape water. 2. Pretreatment to the domestic sewage, and sludge concentration. 3.

However, a large amount of sludge is produced, and 30% to 40% of the cost of waste water treatment is generated by the treatment of sludge. 3. The PH value of tap water changes greatly, and the pH of the reaction tank is unstable. PH instability caused sedimentation tank turbidity. With the water quality is also unstable, good times and bad. 4.
