Dissolved Air Floatation DAF System For Wastewater Teatment Plant
Dissolved Air Flotation (DAF) is a water treatment process that
removes suspended solids
by using air to create a blanket of sludge at the surface of a
flotation cell. This separation is
achieved by dissolving air into the wastewater and then releasing
the air at atmospheric
pressure in a flotation tank.

Key DAF features
1. Air dissolving pump and suction water pump suction, pressure in
mixing, dissolving high
efficiency, fine bubbles is less than or equal to 30um.
2. Low pressure operation, dissolved air efficiency of up to 99%,
the release rate of up to 99%.
3. The effective adsorption of micro bubbles and suspended
particles increased the removal efficiency of SS.
4. Dissolved gas water solution efficiency of 80-100%, 3 times
higher than the traditional
dissolved air flotation efficiency.
5. Pressure - volume curve is smooth, easy to realize automatic
control, easy to operate, easy
to maintain, low noise.
