Nanobubble-enhanced oil-water separations

AquaB’s solution is a CE‑marked, TRL‑9 nanobubble generation technology designed to enhance oil–water separation by overcoming the traditional gas‑solubility bottleneck. 

The system produces highly stable, sub‑100 nm nanobubbles that remain suspended in water, dramatically increasing gas–liquid interfacial area and gas availability. This promotes the adsorption and aggregation of oil droplets and surfactants, thereby improving separation efficiency whilst reducing chemical consumption. 

Unlike conventional aeration or membrane‑based approaches, AquaB’s technology operates in a low‑energy, membrane‑free configuration, eliminating fouling risks and reducing operating costs. Its modular architecture enables straightforward integration into existing treatment infrastructure with minimal disruption. The solution is expected to deliver improved oil removal, lower specific energy consumption, reduced surfactant requirements, and enhanced operational robustness, providing a scalable and sustainable pathway for advanced water treatment and oil–water separation applications.
