Dissolved Air Flotation Daf for Food Industry Wastewater Treatment

Dissolved Air Flotation DAF for Food Industry Wastewater Treatment

Dissolved Air Flotation is mainly for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles with same density as waste water to make the whole float to the surface thus achieve the aim of solid-liquid or liquid-liquid separation.

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 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:

l Separate 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.

l Farm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.

l Manufacturing waste: electroplating, painting, etc.

lPurification: river, landscape, recycle water and so on.
