- Commodity name: Horizontal flow dissolved air flotation machine
Horizontal flow dissolved air flotation machine is widely used in water supply and drainage treatment, which can effectively remove light floating flocs that are difficult to settle in wastewater.

Description of the DAF machine
DAF machine mainly made up of dissolved air flotation system , scraper system and electric control.
1) Dissolved air flotation system : Feeding the clean water into dissolved air tank by the backflow pump from the clean water tank. Meantime,air compressor press the air to the dissolved air tank . Release to inside of the tank after mixing air and water by the releaser
2) Scraper system :scrape the scum floating on the water into the scum tank
3) Electrical Control : The electrical control make the DAF machine reach the best effect

Horizontal flow dissolved air flotation machine is widely used in water supply and drainage treatment, which can effectively remove light floating flocs that are difficult to settle in wastewater. Large processing capacity, high efficiency, small footprint, simple operation, and wide range of use. It is widely used in sewage treatment such as petroleum, chemical industry, printing and dyeing, papermaking, oil refining, leather, steel, food, starch, etc.

Working Principle
The air will be send by air compressor into air tank, then take in air dissolved tank by jet flow device, the air will be force to dissolve into water under 0.35Mpa pressure and forming dissolved air water, then send to air flotation tank.

Under the circumstance of sudden release, the air dissolved in water will be dissolve out and form vast microbubble group, which will be fully contact the flocculating suspended matter in sewage, the suspended matter was sent by pump and flocculation after adding medicine, the ascending microbubble group will adsorb in the flocculated suspended matter, made its density reduce and floated to water surface, thus reach the purpose of removing SS and CODcr etc.

Customer on-site Installation Case
Total suspended solids (TSS) reduction up to 97%
•Chemical oxygen demand (COD) removal up to 85%
•Low-cost operation and maintenance
•Standard and customized units meet a variety of application and flow ranges
•Designed for ease of installation and use
•Suitable for high-salinity water

Advantage

1. Overall specialized, compact structure, and high performance

2. Huge markets ,high maturity, stable performance and reliable operation

3.Hydraulic load: 4~ 12 m3 /(m2h)

4. Maximum inlet SS concentration is 10000 mg/L

5. Automatic scum remoual, solid content can be up to 30 ~ 100 mg/L6.Applied for the wastewater with suspended solids & floc density lighter than wateror close tothe water and weak precipitation phenomenon
1. Separate fine suspended solids and microaggregates such as algae from surface water.

2. Recycling useful substances from industrial wastewater, such as pulp in papermaking wastewater.

3. Replace the secondary sedimentation tank to separate and concentrate sludge in the water.
