High Efficiency Dissolved Air Floatation System

1. Structure and Principle
DAF system uses transfer pump to put the high pressure air and water into the air dissolving tank. The maxing material, air and water, is called “White Water”. When "White Water" mixes slurry in the system, it will release a lot of fine bubbles through the treating tank. The bubbles which attach the upper floc surface of the water become floating residues on the water upper surface above the tank. The scraper device or skimmer of the system will simultaneously remove the floating residues to clarify the liquid by separating the residues and water. Therefore, DAF System has functions both floatation - removing and sedimentation.

2. Purpuse (for DAC & DAR Series)

Filtrate reusing for filter-belt washing.
For the solid and liquid separation of various industry sewage/chemical coagulation treatment.
For the oil and water separation of oil / grease wastewater treatment.
For the treatment of the slurry thickening and reduce the treating cost.
Our DAF be designed for the sludge having smaller specific gravity and smaller operating space, with shorter staying time and stronger air flotation removing ability.
For the paper pulp recycling of paper mill.

3. Features
The machine, solid-liquid equipment, is excessively suitable for conditions including small place and soft sludge. In addition, it is suggested to be employed with other different tanks to save the space of installment.

4. Specification and Functions

Air Dissolving Tank: make use of the vortex pump to feed the clean water and air (equal ratio) each into the Air Dissolving tank (Pressure:3~4kg/cm2 needed) to form the "White Water".
Treating Tank: The waste water mixed with the "White Water", then feeding into the Treating Tank, the "White Water" will wrap up the residues and grease, meanwhile, rise up to the surface of the Treating Tank, then the skimmer plate remove the residues and grease to separate the liquid and solid.
