Structure and Process
Haibar's DAF consists of the main tank basin, mixer tank, air dissolving system, dissolved air back flow pipeline, dissolved air water releasing system, skimming device and control panel. The air floatation separation technology is used to achieve a pure water quality. When flocculants (PAC or PAM, or other flocculants) are added into the water, after an effective flocculation process (time, dosing, and flocculation effects must be tested), the water flows into a contact area where both the flocculants and tiny bubbles float to the surface of the water, forming a scum to be removed using a skimming device. The treated water then flows into a branch water pool, partially back flowing for the DAF system, and the rest is discharged.

Application
Oil-water separation of wastewater in petrochemical industries (including emulsified oil and vegetable oil).
Pretreatment of wastewater in textile, dying, bleaching and wool spinning industries.
Wastewater treatment in surface treatment industries such as galvanization, PCB, and pickling.
Pretreatment of wastewater in pharmacy, chemical, papermaking, tannery, slaughter houses and food industries.
As a replacement for sedimentation tanks, the flotation is widely used in industrial waste water pretreatment.
