1. Oxymo Technology

Key Products & Services: MABR systems, flat sheet MBR membranes, ultrafiltration (UF) modules, membrane distillation, package sewage treatment plants, and full design-to-installation support.

Industries Served: Municipal sewage treatment, printing and dyeing wastewater, papermaking, food processing, slaughtering wastewater, pharmaceutical, dairy, and chemical industries.

Company Overview

Oxymo Technology is a specialist membrane manufacturer built around one core mission. The company focuses entirely on MABR, MBR, and UF hollow fiber membrane technology. It has completed hundreds of water treatment projects across more than 40 countries. This experience covers municipal sewage systems and demanding industrial wastewater streams alike.

What sets Oxymo apart is its research-first approach to membrane development. The company partners directly with universities and scientific institutions on new membrane formulas. This work has produced several invention patents across PVDF, PVC alloy, PAN, and PES membrane types. Oxymo manufactures its MABR, standard UF, and gravity UF product lines at scale.

Oxymo backs its products with internationally recognized quality standards. Its manufacturing facilities operate under ISO 9001 and ISO 14001 certification. The membranes themselves carry CE certification, which matters for procurement teams handling compliance paperwork. Oxymo also provides ongoing technical support and after-sales service for every installation.

What Makes Oxymo Technology Stand Out?

Oxymo Technology offers more than membrane products. It also helps clients find the right system for their wastewater needs. Here are a few reasons why the company stands out:

• Focus on membrane research: Oxymo works with university research teams to improve its membrane technology.
• More than one membrane type: The company works with MABR, MBR, ultrafiltration, and membrane distillation systems.
• Solutions for different wastewater types: Oxymo can design systems for dairy waste, dye wastewater, municipal sewage, and other types of wastewater.
• Custom system design: Each project has different needs. Oxymo can adjust the system based on the wastewater and treatment goals.
• Support from one company: Buyers can work with one manufacturer for different membrane and wastewater treatment needs.

2. Fluence Corporation

Headquarters: White Plains, New York, USA (with additional operations in Minnesota)

Key Products: Aspiral Smart Packaged MABR plants, SUBRE MABR retrofit modules, desalination systems, and wastewater reuse platforms.

Mejec packs its MABR units, controls, and other parts into standard shipping containers. This setup lets the company build units at its factory and ship them fast. Mejec says its system can cut energy use for aeration by up to 75%.

Mejec tests each unit in its own labs before shipment. The company has placed systems in tough settings, including cold parts of North America. Buyers should check if Mejec offers local service in their area.

Conclusion

Wastewater plants face more challenges each year. Stricter nutrient limits force many plants to upgrade old systems. Higher energy costs also make standard aeration costly to run. MABR technology helps solve these problems with bubble-free oxygen transfer. It can cut energy use by up to 90 percent. Plants can also add capacity without building new tanks. Nitrification and denitrification can occur in one reactor chamber.

Choosing the right treatment partner can shape your project’s success. Leading Membrane Aerated Biofilm Reactor Companies in the U.S. offer tested solutions. They support projects from design through long-term maintenance. A trusted partner helps you meet limits and control costs. Your choice affects energy bills, water quality, and daily plant work.

Frequently Asked Questions

What is a membrane-aerated biofilm reactor used for?

An MABR treats city and factory wastewater. It grows a biofilm on air-permeable membranes. Oxymo Technology makes MABR systems for new plants and upgrades to old tanks.

How is MABR different from a standard MBR?

An MBR uses membranes to remove solids from treated water. An MABR uses membranes to send oxygen to a biofilm layer.

Does MABR use less energy than standard aeration?

Yes. MABR sends oxygen without bubbles. This can lower energy use compared with common blower systems.

Which industries benefit most from MABR wastewater treatment?

City water plants, food and drink makers, drug makers, and paper mills use MABR. It helps these sites remove nitrogen from wastewater.
