DAF Clarifier Water Treatment Plant Dissolved Air Flotation Equipment For Sewage
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 Dissolved Air Flotation
Oil Water Separator Wastewater Plant Treatment DAF Dissolved Air Flotation is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.
Principle of Dissolved Air Flotation
DAF dissolved air flotation consists of flotation tank, dissolved air system, reflux pipe, dissolved air released system, skimmer (Based on customer needs, there are combined type, traveling type and chain-plate type to choose.), electric cabinet and so on.
Air flotation separation technology of Benenv DAF dissolved air flotation dissolves air into water at certain working pressure. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel. The microscopic air bubbles produced by released air attach to suspended solids and float them to the surface, forming a sludge blanket. A scoop removes the thickened sludge. Finally, it complete purifies the water.
Air flotation technology of DAF dissolved air flotation plays an important role in solid-liquid separation (Simultaneously reduce COD, BOD, chroma, etc). Firstly, mix flocculating agent into raw water and stir thoroughly. After the effective retention time (lab determines the time, dosage and flocculation effect), the raw water enters into the contact zone where microscopic air bubbles adhere to the floc and then flows into the separation zone. Under the buoyancy effects, the tiny bubbles float the flocs to the surface, forming a sludge blanket. A skimming device removes the sludge into the sludge hopper. Then the lower clarified water flows into the clean-water reservoir through the collecting pipe. Some of water are recycled to the flotation tank for the air dissolving system, while others will be discharged.

Application Industry
The aim of dissolved air flotation is to separate the fine suspended solids in water, algae and micro-floc. And dissolved air flotation 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.
Packing and Delivery
1. The normal package is wooden box(Size: L*W*H). If export to European countries,the wooden box will be fumigated.If container is too tighter,we will use pe film for packing or pack it according to customers special request.
2. We also support 20',40' container delivery, use soft packaging to protect machine well. If export to european countries,the wooden box will be fumigated.If container is too tigher,we will use pe film for packing or pack it according to customers special request.
