PMnB is a chemical-free water and wastewater treatment system developed by Palgey Maim, a global engineering company with over 50 years of experience in water treatment.
PMnB uses nano bubble technology to deliver gases such as ozone, oxygen, or air more efficiently in water. This improves treatment performance across municipal, industrial, agricultural, and environmental applications, without chemical dosing.
in energy cost savings
less ozone required
retrofit-ready systems
improvements without re-dosing
PMnB is designed for processes limited by oxygen transfer, oxidation, or disinfection efficiency.
Unlike conventional bubbles that rise quickly and escape, nano bubbles remain suspended in water, allowing longer contact time and more effective gas transfer. This enables treatment goals to be reached with lower gas input, simpler operation, and reduced operational burden.
No chemical handling, storage, or dosing systems
Improved performance in aeration-intensive processes
Easy integration into existing treatment plants
Proven in continuous, real-world operations
Nano bubbles are smaller than one micron and remain stable in water for extended periods, improving gas dissolution and transfer efficiency.
Ozone, oxygen, air, and other dissolved gases are delivered efficiently, reducing required gas flow and energy demand.
Sustained gas contact supports oxidation and biological processes across primary, secondary, and tertiary treatment stages.
PMnB systems are deployed in wastewater plants, reservoirs, agricultural systems, and industrial facilities worldwide, and are engineered for retrofit installation without major civil works or operational disruption

Nano bubbles are gas bubbles smaller than one micron that remain suspended in water for extended periods. Unlike larger bubbles that rise quickly, nano bubbles provide longer contact time and higher gas transfer efficiency.
PMnB delivers oxygen or ozone efficiently using nano bubbles, enabling oxidation and disinfection without chlorine or repeated chemical dosing.
PMnB systems can infuse ozone, oxygen, air, and other process gases depending on the application.
Because nano bubbles transfer gas more efficiently, PMnB systems achieve treatment targets with significantly lower aeration energy than conventional systems.
