OPTION B: CONDITIONING
Maximizing floc formation
From Flotation to Coagulation
1. Attachment:
NBs target sub-20μm particles that microbubbles miss.
2. Nucleation:
Formation of gas-solid composite nuclei.
3. Bridging:
Nanobubbles link particles, creating microflocs with density < water.
-
Collision probability approaches unity.
-
Removes reliance on chance contact.
Unlocking Biological Efficiency
The Invisible Bottleneck
Surfactant films reduce oxygen transfer (kLa) by up to 50%.
The Fix: UFBs strip films
The Barrier: Surfactant films reduce oxygen transfer (kLa)
by up to 50%.
The Fix: UFBs strip films via interfacial tension and oxidation. Interfacial Tension
The Domino Effect: Removal of inhibitors > Higher Alpha Factor >
