DAF Dissolved Air Flotation System Working Principle
The DAF dissolved air flotation system dissolves air into wastewater under pressure and releases millions of fine micro-bubbles. Suspended solids, oil and grease attach to the micro-bubbles and rise to the surface, where an automatic skimmer removes the sludge layer. Sedimentation occurs during the flotation process, which is particularly serious in the wastewater pre-treatment section, and a large amount of sediment affects the quality of the effluent and the stability of the operation. This DAF air flotation machine can effectively eliminate sediment to ensure the stable operation of the flotation process.

Applications
1. WWTP sewage pretreatment, upgrading and phosphorus removal. 2. Industrial wastewater pretreatment: food processing, textile printing and dyeing, semiconductors, machinery, steel and chemical industries. 3. Water treatment plant algae removal. 4. River and lake purification and landscape water treatment. 5. Desalination projects.
Application Case
Textile wastewater treatment case of Nopont Nonwovens. Industry: Textile Wastewater. Capacity: 120 m3/h. Product: Shallow air flotation SAF. Nopont Nonwovens produces a large amount of textile wastewater with high COD and BOD content, deep chromaticity, textile fiber impurities, grease and inorganic salts. The DAF dissolved air flotation system effectively removes suspended solids and directly settleable impurities, regulates water quality and quantity, and features short hydraulic retention time and small base load, ideal for treating large volumes of textile wastewater.
