ORANANO™ – NanoBubble Generators | The Future of Water & Wastewater Treatment

ORANANO™ Nanobubble Generator Technology by ORAIPL

ORAIPL’s ORANANO™ Nanobubble Generator is an advanced, high-efficiency solution designed to revolutionize water and wastewater treatment through cutting-edge nanobubble technology. By generating ultra-fine nanobubbles that remain suspended in water for extended periods, ORANANO dramatically enhances oxygen transfer, accelerates biological treatment, and improves contaminant removal — all while reducing energy consumption and chemical dependency.

Developed for industrial, municipal, and environmental applications, ORANANO nanobubble generators deliver superior performance compared to conventional aeration and treatment systems.

What Is Nanobubble Technology?

Nanobubbles are gas bubbles with diameters typically less than 200 nanometers. Unlike conventional bubbles, nanobubbles:

  • Remain stable and suspended in water for long durations

  • Exhibit a high surface-area-to-volume ratio

  • Create strong oxidation and mass-transfer effects

  • Enable exceptional gas dissolution efficiency

In water and wastewater treatment, nanobubbles significantly improve oxygen availability, enhance biological activity, and promote the breakdown of organic and inorganic pollutants — making them ideal for modern, sustainable treatment processes.

How ORANANO™ Nanobubble Generators Work

ORAIPL’s ORANANO™ Nanobubble Generator uses a proprietary hydrodynamic and gas-liquid interaction process to generate uniform, ultra-fine nanobubbles.

Process Overview

  • Controlled gas injection (air, oxygen, ozone, or other gases)

  • High-shear nano-generation chamber

  • Formation of stable nanobubbles

  • Even dispersion throughout the treatment volume

Once introduced into water, nanobubbles:

  • Increase dissolved oxygen (DO) levels

  • Enhance microbial activity in biological treatment

  • Promote oxidation of contaminants

  • Improve overall treatment kinetics

Key Benefits of ORANANO™ Nanobubble Technology

1. Exceptional Oxygen Transfer Efficiency

ORANANO nanobubble generators achieve up to 80–90% oxygen transfer efficiency, far exceeding conventional aerators. This results in faster biological degradation of pollutants and improved process control.

2. Chemical-Free Water & Wastewater Treatment

Nanobubbles enhance oxidation and microbial activity without the need for excessive chemicals, supporting eco-friendly and sustainable operations.

3. Energy & Operating Cost Reduction

Due to higher oxygen utilization and reduced aeration demand:

  • Lower power consumption

  • Reduced blower and compressor sizes

  • Decreased overall OPEX

4. Improved Effluent Quality

Consistent improvement in key outlet parameters:

  • Reduced BOD & COD

  • Improved ammonia and nitrogen removal

  • Better phosphorus reduction

  • Lower sludge generation

5. Odour & Sludge Control

Nanobubble-induced oxidation helps suppress anaerobic conditions, reducing odour formation and minimizing excess sludge production.
