UFBLab Nanobubble DAF

6/5/20261 min read

Nanobubble-enhanced Dissolved Air Flotation (DAF) improves wastewater treatment by using ultra-fine bubbles (

<200 nm to 5𝜇m) to significantly increase air-solid contact, boosting suspended solids and fat/oil removal efficiency by over 30%. These durable bubbles stay suspended for weeks, reducing reliance on chemicals and lowering operating costs compared to conventional DAF, which produces larger bubbles.

Key Benefits of Nanobubble DAF

Superior Separation: Nanobubbles remain in water longer and provide a much greater surface area (over 100 times more than conventional bubbles) to attach to smaller particles, oils, and fats.
Higher Efficiency & Faster Operation: Systems using UFBLab's technologies can increase dissolved oxygen levels by up to 200%, enhancing biological treatment, and improving efficiency in removing fats, oil, and grease (FOG).
Lower Operating Cost: These systems remove the need for large compressors, pressure tanks, and flocculants.
Smaller Footprint: DAF systems using gas liquid DAF Pumps often combine the pump, motor, and saturator into a single unit, saving space.

Common Applications

Wastewater Treatment: Removing FOG (fats, oils, grease) and suspended solids.
Municipal WWTP: Improving BOD, COD, and suspended solid removal rates.
Industrial Processes: Treating dairy wastewater, poultry processing, and removing microplastics (up to 95-97% efficiency).
