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

A wastewater treatment upgrade reduced effluent quality in a 390,000 m³ reservoir. PMnB restored treatment performance using floating ozone nano bubble systems.
A landfill site required a solution to prevent odor formation and stabilize leachate stored in a 49,500 m³ evaporation pond. PMnB installed ozone-based nanobubble systems to maintain aerobic conditions and control sulfide-related issues without chemical dosing.
Poor reservoir water quality threatened reliable irrigation and crop health. PMnB was installed to control algae and biofilm in irrigation water.
A municipal facility required a chemical-free alternative for tertiary disinfection. PMnB implemented ozone nano bubble disinfection using floating units.
A 300,000 m³ reservoir receiving secondary-treated municipal effluent did not meet Ministry of Health quality requirements for irrigation reuse. PMnB was deployed using floating ozone nano bubble systems to improve oxidation and stabilize effluent quality without chemical dosing.
A large municipal wastewater reservoir system (500,000 m³ total volume, 2,500 m³/day flow) required advanced oxidation to meet Ministry of Health quality requirements for irrigation reuse. PMnB implemented floating ozone nano bubble systems to enhance oxidation efficiency and improve effluent quality.
An offal slaughterhouse facility required reliable sulfide reduction to meet discharge limits. PMnB was installed after anaerobic treatment to improve oxidation.
A PMnB ozone nano bubble system was installed on an effluent reservoir recirculation line to improve secondary effluent quality. The reservoir had become anaerobic with poor water quality (high BOD/COD, high turbidity). PMnB ozone nano bubbles restored oxygen levels and significantly improved effluent quality within practical operating timelines.
Severe odors from a wastewater reservoir in an industrial area caused public complaints. PMnB restored aerobic conditions across the reservoir.
A 370,000 m³ reservoir storing tertiary-treated wastewater experienced algae growth and declining effluent quality following irregular discharge during 2023, leading to disqualification for irrigation reuse. PMnB implemented floating ozone nano bubble systems to restore oxidation efficiency, control algae, and stabilize reservoir water quality.
A drinking water operator needed to reduce pathogens while significantly lowering chlorine use. PMnB implemented ozone-based nano bubble disinfection to improve treatment performance.
High iron and manganese levels had taken critical drinking water wells out of service. PMnB applied ozone nano bubble oxidation with sand filtration to restore well operation without chlorination infrastructure.
A 30,000 m³ irrigation reservoir required algae and biofilm control to protect irrigation performance. PMnB improved water clarity and stabilized reservoir conditions.
Poor soil oxygenation and root disease pressure were impacting avocado tree health and long-term productivity. PMnB was installed as a bypass on the irrigation line to deliver oxygen nano bubbles directly into the root zone.

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.
