DAF dissolved vapor sought floating

Floating principle

Floating is a solid and liquid or liquid-liquid separation techinology, mainly used to remove the water is difficult to settlement and relative density in the water close to tiny suspended solids, colloid, oil and grease kind material.

Floating in the process of developing a large fine and uniform bubbles(10-100μm), to these little bubbles as the carrier, and the water was suspended particles, contact fully mixing body, adhesion, form clip gas was floating body to liquid surface. Bubbles, water and flocculen body(oil) three-phase hybrid, through the scraping the foaming machine collect foam or scum to separate impurity, the purpose of purifying water quality.Dissolved vapor in the air flotation system, under high pressure air into the water and close to capacity, and then to the atmospheric pressure release state, at this moment the supersaturated air will dissolve in tiny bubbles separation from the water and floating.

Floating application

1. Separation of the water tiny suspended solids, monen and micro algae flocculant body(such as landscape water, water purification, and the depth of the waste water processing)
2. Separation recycling waste money floating in the oil and grease(such as petrochemical wastewater, oil extraction, back to the water injection process, biodiesel and catering waster water)
3. High concentration organic wasterwater pretreatment money(such as chemical, pharmaceutical and other waste water)
4. Biochemical water(money to replace the second pond) out of the water, Fenton solid-liquid separetion and the active sludge concentration.
5. Money papermaking ,printing, dyeing, the leather making, the fermentation, food and so on the sewage treatment
6. Breeding, such as money slaughter wastewater treatment.
7. Money spraying, electroplating and other waste water and heavy metal recycling.
