Dissolved Air Flotation (DAF) Equipment
Horizontal Dissolved Air Flotation Machine
The horizontal dissolved air flotation (DAF) machine is a high-efficiency device for solid-liquid and liquid-liquid separation. Through a dissolved-air system, air is dissolved in water under pressure and then released as fine micro-bubbles under reduced pressure. The bubbles attach to suspended solids, oil and other impurities, carrying them to the surface where they are skimmed off by a scum scraper. Offering good treatment performance and simple operation, it is widely used in oily wastewater, papermaking wastewater, printing and dyeing wastewater, and food processing wastewater.
Combined DAF & Sedimentation Unit
The combined DAF and sedimentation unit integrates dissolved air flotation and sedimentation. It first removes light suspended solids and oil through DAF, then removes remaining suspended solids in the sedimentation zone, suitable for treating oily wastewater and industrial wastewater.
Shallow DAF Machine
The shallow DAF machine is designed based on the shallow-tank principle, with a short bubble rise distance and fast separation speed for high treatment efficiency. It is suitable for papermaking whitewater recovery, oily wastewater, food wastewater and municipal sewage pretreatment.
