NANOPOREX bubble generators introduce finely dispersed gas bubbles into the water, significantly enhancing mixing and expanding the surface area available for gas-liquid mass transfer. This innovative approach leads to heightened efficiencies in both chemical and biological processes. The Nanoporex bubble generator increases the mass transfer surface area almost 1000 times more than drilled pipe or diffusers conventionally used in Industry.
Process Operations
The gas is dispersed as a fine mist of bubbles, increasing the mass transfer area. When liquid-gas interphase reactions occur, the heightened surface area improves gas-liquid mixing efficiency.
Features & Advantages
NANOPOREX bubble generators use cavitating devices to create billions of fine bubbles.
Increase the surface area in a two-phase reaction between gases and liquid, achieving very fast, efficient mass transfer.
