Municipal Wastewater Treatment Using Chemical-Free Nano Bubble Technology

PMnB delivers advanced municipal wastewater treatment solutions designed to improve water quality, reduce energy consumption, and support regulatory compliance across wastewater treatment plants. Using chemical-free nano bubble technology, PMnB enhances oxidation and oxygen transfer in aerobic treatment, sludge treatment, and tertiary disinfection treatment processes.

Challenges facing municipal wastewater treatment plants

Municipal wastewater treatment plants must reliably treat wastewater streams while managing rising energy costs, aging infrastructure, and tightening discharge standards. 

High energy demand in aerobic treatment units and aeration systems
Inconsistent removal of organic matter and suspended solids
Odor and sulfide generation during sludge treatment and sewage sludge handling
Limitations in existing disinfection systems, including UV disinfection under variable water quality
Difficulty achieving stable treated wastewater quality without chemical dosing

How PMnB improves municipal wastewater treatment performance

PMnB uses stable nano bubbles to improve gas dissolution and oxidation in municipal wastewater treatment. Because nano bubbles remain suspended longer than conventional bubbles, PMnB increases oxygen availability and oxidation efficiency across aerobic treatment, tertiary disinfection treatment, and sludge treatment, without chlorine, algicides, or re-dosing.

Applications across the municipal wastewater treatment process

Aerobic treatment

PMnB improves oxygen transfer efficiency in aerobic treatment units, reducing the energy required to maintain dissolved oxygen levels while supporting stable biological treatment.

Lower aeration energy consumption
Improved removal of organic matter
More consistent performance in secondary treatment processes

Tertiary disinfection treatment

PMnB supports tertiary disinfection treatment by improving oxidation prior to filtration or UV disinfection. This enhances overall disinfection process efficiency and helps treatment plants meet reuse or discharge standards.

Improved water quality entering UV disinfection systems
Reduced chemical demand in tertiary treatment
Support for nutrient removal and polishing stages

Sludge treatment

PMnB enhances sludge treatment processes by improving aerobic digestion, reducing sulfide formation, and supporting thickening and dewatering operations.

Improved sewage sludge stabilization
Reduced odors during sludge treatment
Better performance of sludge thickeners and sludge dewatering systems
Higher dry solids content and more stable sludge handling

What types of municipal wastewater treatment processes can PMnB support?

PMnB can be applied across aerobic biological treatment, tertiary disinfection and polishing processes, sludge treatment, and effluent reservoirs. It is used where oxygen transfer, oxidation efficiency, and treatment stability limit performance in municipal wastewater treatment plants.

PMnB improves oxygen transfer efficiency in aeration-intensive processes, allowing plants to maintain required dissolved oxygen levels with significantly lower blower or aerator runtime. This results in substantial energy savings while maintaining stable biological treatment performance.

Yes. PMnB helps maintain aerobic conditions and enhances oxidation in sludge treatment systems, reservoirs, and lagoons where sulfide formation typically occurs. This reduces odors, improves sludge stabilization, and supports more reliable downstream sludge handling.

PMnB improves oxidation prior to filtration or UV disinfection, resulting in more consistent effluent quality entering tertiary treatment systems. This enhances disinfection efficiency, supports pathogen reduction, and helps plants meet reuse or discharge standards without chemical dosing.

PMnB systems are designed for retrofit into existing basins, reservoirs, and tertiary treatment processes. Integration requires minimal disruption, does not involve chemical storage or handling, and is scalable for both small facilities and large municipal wastewater treatment plants.
