Industry Wastewater Treatment Plant with Sludge Scraper Equipment DAF System for Water Treatment

Industry Wastewater Treatment Plant with Sludge Scraper Equipment DAF System for Water TreatmentProduct Description
Dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 from water.Dissolved Air Flotation 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 dissolved air flotation is an innovation combined with traditional dissolved air flotation concept and modern technology. 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 flotationdissolves 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.Cooperation Case
Application in Various 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:
lSeparate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.
lHigh concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.
lBiochemical 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.
lFarm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.
lManufacturing waste: electroplating, painting, etc.
lPurification: river, landscape, recycle water and so on.Related Products
