NANOPOREX-E
Nanobubble Technology for Advanced Water & Wastewater Treatment
NANOPOREX-E from Diva Envitec Pvt Ltd is an advanced nanobubble generation technology engineered to enhance physical, chemical and biological processes across a wide range of water and wastewater treatment applications.
By generating stable nanobubbles, typically in the 100–200 nm range, NANOPOREX-E creates a high gas–liquid interfacial area and prolonged bubble residence time, enabling more efficient gas transfer and interaction within the liquid phase.
The technology can be applied to enhance aeration and oxygen transfer, biological treatment, oxidation processes, flotation and separation, odour control, algae management, and overall water-quality improvement. Its versatility enables integration into municipal and industrial wastewater treatment, water treatment, reuse and recycling systems, and specialised environmental applications.
Nanobubble Physics & Gas–Liquid Mass Transfer
Nanobubble generation
produces ultra-fine bubbles (100-200 nm) with extremely high surface area and stability, ensuring prolonged presence in water.
Enhanced oxygen transfer
nanobubbles improve oxygen dissolution efficiency, supporting aerobic biological processes like MBBR.
Reactive oxygen species (ROS) formation
generates ROS and hydroxyl radicals that oxidise organic pollutants and pathogens.
Electrostatic interaction
charged nanobubbles attach to suspended particles, aiding in flotation and separation.
Multi-mechanism treatment
supports oxidation, flotation, and adsorption simultaneously, improving overall treatment performance.
Oxygen Transfer & Process Intensification Benefits
Chemical-free and environmentally sustainable process
High oxygen transfer efficiency compared to conventional aeration
Stable nanobubbles with long residence time
Enhances biological treatment performance (MBBR/ASP)
Supports removal of organics, pathogens, and suspended solids
Versatile across multiple industrial applications
Reduces energy and chemical consumption
Aeration, Oxidation & Flotation Applications
- MBBR and biological wastewater treatment systems
