Efficient Filtration Pretreatment for Industry Wastewater Treatment Plant DAF Dissolved Air Flotation Equipment
DAF equipment is liquid/solid or liquid/liquid separation process to remove tiny suspended solids that density close to the water, colloid ,oil and grease etc. Benenv DAF equipment is an innovation combined with traditional dissolved air flotation concept and modern technology.
Brief Introduction of DAF Equipment
A large numbers of fine and uniform bubble (5 ~ 80μm), bubbles, water, floc (oil) three-phase mixture, as a carrier, bubbles mixed with floc particles suspended in the water. Connect, adhesion, form floc with bubbles and float to the liquid surface, scraping scum to achieve separation of impurities, water purification .

Application Industry
The aim of DAF equipment is to separate the fine suspended solids in water, algae and micro-floc. And DAF equipment can be used in the following industries:
l Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.
l High concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.
l Biochemical effluent liquid separation: the anaerobic effluent solid-liquid separation, aerobic (activated sludge process, contact oxidation, filter) biochemical water solid-liquid separation, the secondary settling tank Effluent treatment and so on.
l Farm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.
l Manufacturing waste: electroplating, painting, etc.
l Purification: river, landscape, recycle water and so on.
Characteristics Advantages
