english Cavitation Air Flotation Technology
1. Cavitation Effect Generates Microbubbles
- Cavitation Air Flotation uses a special device to create a cavitation effect
- Forms a large number of tiny bubbles in the water
- Water flows through a specific structure, creating localized low-pressure zones
- Dissolved gases release and form tiny, evenly distributed bubbles
- Large surface area provides ample attachment for grease adsorption
2. Bubble-Grease Adsorption
- Grease in wastewater exists as tiny, hydrophobic droplets
- Microbubble surfaces also have hydrophobic properties
- Oil droplets and bubbles collide and contact through water flow
- Surface tension and hydrophobic interactions cause adhesion
- Active substances on bubble surfaces enhance grease capture
3. Bubble-Carrying Oil Floatation
- Bubbles with adsorbed grease float upward due to buoyancy
- Some bubbles coalesce to form larger bubble groups
- Oil-containing bubbles gather on water surface
- Forms a stable scum layer separating oil from water
4. Scum Removal and Effluent Purification
- Oil-containing scum is removed by scraping/skimming equipment
- Oil content in water is significantly reduced
- Remaining tiny oil droplets undergo further purification
- Cavitation effect continuously generates bubbles for stable separation
