PMnB is a chemical-free water treatment technology platform developed by Palgey Maim, a water engineering company with more than 50 years of experience designing, building, and operating water and wastewater infrastructure. Palgey Maim has delivered hundreds of water management projects across municipal, industrial, and agricultural sectors worldwide, earning a reputation for engineering reliability in regulated water environments.
PMnB represents the next evolution of that expertise: a dedicated nano bubble water treatment system that improves water quality, reduces dependence on traditional chemical treatments, and upgrades aging infrastructure without
requiring full plant rebuilds. By infusing stable nano bubbles with dissolved gases such as ozone, oxygen, and air, PMnB enhances gas transfer efficiency, strengthens biological treatment processes, and delivers advanced oxidation performance, all with low energy consumption and no chemical storage, handling, or dosing.
PMnB systems are engineered for real-world conditions, designed to retrofit into existing water treatment plants, reservoirs, and industrial facilities, and backed by Palgey Maim’s decades of hands-on operational knowledge.
PMnB is a nano bubble water treatment system designed for new installations or retrofit integration into operating water treatment plants and wastewater systems. Our technology removes contaminants and improves water quality without the environmental impacts associated with traditional chemical water treatment methods.
We help operators achieve better treatment processes and long-term process stability by focusing on three core outcomes:
Improved dissolved oxygen stability strengthens biological treatment processes, reducing the need for supplemental chemical treatments and lowering overall environmental footprint.
Advanced oxidation of organics, sulfides, and odor-forming compounds delivers results comparable to or exceeding traditional water treatment approaches, including activated carbon and conventional chemical dosing, without adding harmful chemicals to your water treatment system.
Efficient ozone delivery reduces chlorine dependence for drinking water and process water applications, supporting cleaner treatment processes and improved water quality across municipal and industrial operations.
PMnB projects are delivered through a structured engineering process that prioritizes performance under continuous operation. Unlike conventional water treatment technology that often requires extensive civil works, our approach is designed for minimal disruption:
Evaluate system constraints, current water management practices, and treatment goals.
Pinpoint where gas transfer and oxidation inefficiencies limit results in your water treatment plant or facility.
Engineer retrofit integration with minimal disruption to existing treatment processes.
Confirm performance against defined KPIs, including water quality benchmarks and reducing chemical usage targets.
PMnB operates under Palgey Maim, combining nano bubble water treatment technology with more than five decades of engineering execution in regulated water environments. This foundation means PMnB is built for real infrastructure constraints, not ideal laboratory conditions.
Our systems are designed for long-term reliability, low maintenance, and practical operation across diverse water management challenges. From municipal water treatment plants to industrial effluent systems and agricultural reservoirs, Palgey Maim’s engineering integration model ensures that every PMnB deployment is designed, commissioned, and optimized for the specific conditions of each site.
PMnB has been implemented in municipal and industrial water treatment systems across multiple countries to improve oxygen transfer efficiency, oxidation performance, and process stability under continuous operation. Our deployments span reservoir-scale floating systems, inline treatment integration, and ozone-enhanced advanced oxidation, delivering measurable improvements in water quality and reducing chemical dependency across every installation.
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.
