Proven BOD/COD Reduction & Pathogen Elimination

Advanced Nanobubble Solutions for Wastewater Treatment

NBT’s patented nanobubble technology transforms wastewater treatment by delivering ultra-fine oxygen and ozone nanobubbles that significantly improve dissolved oxygen levels and gas transfer efficiency throughout the treatment system. This advanced process accelerates the breakdown of organic matter, reduces BOD and COD, and improves effluent quality more effectively than conventional aeration systems.

The result is faster, chemical-free treatment with cleaner effluent, reduced sludge production, lower energy consumption, improved pathogen control, and easier regulatory compliance, while reducing reliance on traditional chemical treatments.

Dealing with High BOD, COD, Odours, Pathogens, and Compliance Pressure?

Industrial, municipal, and commercial wastewater streams typically contain high concentrations of organic matter, suspended solids, pathogens, and volatile compounds. These conditions produce elevated BOD and COD, persistent and offensive odours, significant discolouration, excessive sludge generation, and high operational and energy costs.

Conventional treatment systems reliant on mechanical aeration, chemical dosing, and extended retention times are often inefficient, costly, and unable to keep pace with tightening discharge regulations, creating ongoing compliance exposure and reputational risk.

Transforming Wastewater Treatment with Oxygen & Ozone Nanobubbles

NBT Nanobubble Technology enhances wastewater treatment by introducing ultra-fine oxygen and ozone nanobubbles directly into the wastewater stream. These stable nanobubbles remain suspended for extended periods, significantly improving dissolved oxygen levels and gas transfer efficiency throughout the entire treatment volume.

Through advanced oxidation, the system rapidly breaks down organic pollutants, pathogens, biofilms, and odour-causing compounds without chemical additives. Ozone naturally decomposes back into oxygen within 20–30 minutes, leaving no harmful residues and eliminating chemical handling requirements.

The result is improved treatment performance, lower sludge production, reduced energy consumption compared to conventional aeration systems, and stronger compliance with discharge regulations across municipal, industrial, and commercial wastewater facilities.

Measurable Improvements You Can Expect in Your Wastewater Operation

High Gas Transfer Efficiency (>85%)

Significantly higher oxygen/ozone dissolution and reduced aeration energy (30–50%).

Advanced Oxidation

Rapid breakdown of organics, biofilms, and odour compounds

High-Level Pathogen Reduction (>99%)

Strong oxidation eliminates bacteria, viruses, and microbes, improving effluent safety without chemical disinfectants.

Odour and Colour Elimination

Effectively oxidises VOCs and coloured organics, converting dark, odorous wastewater into clearer effluent quickly.

Reduced Sludge Volume & Suspended Solids

Improved oxidation and flotation reduce solids and sludge, cutting disposal costs and boosting efficiency.

Chemical-Free, Sustainable Operation

Ozone decomposes to oxygen without residues, reducing chemicals, improving the environment, and lowering costs.
