Dissolved Air Flotation Units DAF Machine For Sewage Treatment Plant
Product Description
1. Description
Dissolved Air Floatation is mainly for solid-liquid or liquid-liquid separation. Large sum of micro
bubbles produced by dissolving and releasing system adhere to solid or liquid particles with
same density as waste water to make the whole float to the surface thus achieve the aim of
solid-liquid or liquid-liquid separation.
2. Application
(1) Remove oil and TSS.
(2) Separate small particles and algae in groundwater.
(3) Recover valuable products in industrial sewage such as paper pulp.
(4) Act as secondary sedimentation tank to separate and concentrate suspended particles
and sludge.
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.
Principle of DAF
The DAF Separator provides effective separation of suspended solid, fats , oils and greases
from liquids by dissolved air flotation . Flotation of the solids is accomplished by the
introduction of tinny air bubbles into the process water.AS the bubbles rise ,they attach
themselves to the particales in suspension
