Oraipl - Model ORANANO -Nanobubble Generator

What Is Nanobubble Technology?

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

• Enable exceptional gas dissolution efficiencyRemain stable and suspended in water for long durations
• Exhibit a high surface-area-to-volume ratio
• Create strong oxidation and mass-transfer effects

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.

Sector / Use Case: Typical Benefits with ORANANO NBT

• Municipal & Industrial Wastewater Treatment: Enhanced BOD/COD removal; reduced sludge volume; more efficient aeration; possible chemical-free disinfection; lower operational costs
• Industrial Effluent / FOG / Colloidal Waste: Better separation of oils, grease, suspended solids; improved flotation and filtration; safer discharge compliance
• Aquaculture & Fisheries: Higher dissolved oxygen → healthier fish/shrimp; improved growth, reduced mortality; lower disease risk; reduced chemical use (algaecides, antibiotics)
• Agriculture & Horticulture / Irrigation & Hydroponics: Oxygen-rich water improves root respiration, nutrient uptake; healthy plants, higher yield; reduced pathogen load in irrigation water
• Lakes, Ponds, Rivers, Ecosystem Restoration: Water clarity improvement; algae bloom control; sediment remediation; natural ecological balance without chemicals
• Pre-treatment / Flotation / Industrial Water Reuse: Better removal of suspended solids, oils, colloids; improved water reuse quality; reduced chemical coagulant requirement
