NANOPOREX-E

Engineering Oxygen Transfer at the Nanoscale

NANOPOREX-E from Diva Envitec Pvt Ltd utilises advanced nanobubble generation technology to significantly enhance aeration and treatment efficiency in wastewater systems. By generating stable nanobubbles (100-200 nm), the system improves oxygen transfer, promotes oxidation, and supports biological processes such as MBBR, while remaining a clean and chemical-free solution.

Nanobubble Physics & Gas–Liquid Mass Transfer

  1. Nanobubble generation

    produces ultra-fine bubbles (100-200 nm) with extremely high surface area and stability, ensuring prolonged presence in water.

  2. Enhanced oxygen transfer

    nanobubbles improve oxygen dissolution efficiency, supporting aerobic biological processes like MBBR.

  3. Reactive oxygen species (ROS) formation

    generates ROS and hydroxyl radicals that oxidise organic pollutants and pathogens.

  4. Electrostatic interaction

    charged nanobubbles attach to suspended particles, aiding in flotation and separation.

  5. Multi-mechanism treatment

    supports oxidation, flotation, and adsorption simultaneously, improving overall treatment performance.
