DAF Process
Dissolved Air Flotation is a liquid/solid or liquid/liquid separation process.
It can be used to remove fine suspended solids with density similar to
water, colloid and oil & grease etc.
Removal is achieved by dissolving air (in high pressure) in the form of tiny
bubbles (10-100um for micro bubble and 10-100nm for nano bubble) in the
wastewater. The micro/nano bubbles adhere to suspended matter causing
the suspended matter to float to the surface of the water and form a layer
which is then removed by a skimmer. The forth-free water exits the
flotation tank as the clarified effluent from the DAF unit.
DAF Applications
Fine suspended matter, alga and micro flocs separation ( such as
landscape water treatment, river clarifying and enhanced treatment)
Suspended solids and oil & greases separation and recovery ( such as
petroleum wastewater, biodiesel and restaurant wastewater)
High concentration organics wastewater pretreatment (such as
chemical, pharmacy wastewater)
Outlet wastewater from biological tanks (replacing secondary clarifier),
outlet wastewater from the Fenton process and active sludge thickening
Paper & pulp, printing & dyeing, leather, fermentations, food wastewater
treatment
Aquaculture, slaughter wastewater treatment
Spray, electroplating wastewater treatment and heavy metal recovery

IAF is a technology specialized in removing high concentration oil & grease and SS in industrial
wastewater. The untreated wastewater enters into an aeration segment with aeration equipment at
first. The vacuum effect will be created by a high speed rotation air impeller when the wastewater is
in the progress of up-flow and air sucked into the cavity of the impeller. Then the micro bubbles will
be generated by attrition. The micro/nano bubbles will attach to suspend matter in the wastewater
and float to the water surface. The suspended matter will be removed by special skimmer.

SAF unit is a highly efficient shallow air flotation system adopting the “shallow tank theory” and
“zero-speed principle” successfully. Under a certain pressure the air will excellently dissolve into the
water until saturated.
The water pressure is lowered in high efficiency air releaser, which produce high amount of micro-
bubbles. The produced micro/nano-bubbles and the suspended matter attach to each other and float
to the surface of the water. The suspended matter will be removed by a special skimmer. The depth of
the shallow tank is only 450-600mm and HRT is about 3-5min, which will reduce retention time and
improve flotation efficiency greatly.
