Industries that generate high volumes of process water and effluent face growing pressure to treat it before discharge or reuse. With increasingly stringent discharge standards, high water prices, and tougher inspections, factories, cities, and industrial facilities are seeking to move away from traditional treatment. One of the most reliable ways to meet these targets is with membrane-based systems, which filter contaminants at a microscopic level.

The selection of the right partner is important, as it impacts plant uptime, effluent quality, and long-term operating costs. There are variations among companies in the type of material used for membranes, how the membranes are customized to specific wastewater streams, production capacity, certification standards, and technical support after installation. Choosing an incorrectly sized system can lead to increased energy consumption, frequent membrane fouling, or non-compliant effluent.

This guide introduces you to 10 wastewater treatment firms that employ advanced membrane technology, the products and capabilities they offer, the industries they serve, and the considerations you should make when deciding on a supplier.

Company Overview

Oxymo Technology offers customized MBR and ultrafiltration systems for municipal and industrial wastewater treatment applications. It focuses on a technology known as hollow fiber membrane technology, a process that combines membrane filtration and biological treatment to remove suspended solids and pathogens from wastewater streams prior to discharge. Oxymo is one of the wastewater treatment companies that specialize in advanced membrane technology, providing both membrane products and package treatment plants under one roof.

The company owns patents on a variety of different membrane materials, such as embedded-reinforced PVDF, PVDF, alloy-PVC, PAN, and PS/PES, each suited to different filtration precision requirements and wastewater conditions. Instead of always recommending one single formula to all customers, Oxymo correlates the chemistry of membranes with the application. It offers MBR, MABR, standard UF, and gravity UF product lines.

This flexibility is important as the composition of wastewater varies according to industry and season. Oxymo’s projects across more than 40 countries have processed wastewater from slaughterhouses, dairies, landfill leachate, and more, all manufactured to ISO 9001 and ISO 14001 standards.

What makes Oxymo Technology stand out?

• Multiple patented membranes (embedded-reinforced PVDF, PVDF, alloy-PVC, PAN, PS/PES) rather than one chemistry, allowing customers to select filtration accuracy that matches their wastewater stream.
• A complete product range spanning MBR, MABR, standard UF, and gravity UF — from package plants to larger systems for municipal applications.
• Full-service project support — design, manufacturing, technology guidance, and after-sales service — not just membrane hardware.
• Production certified to ISO 9001 and 14001, installations in over 40 countries, municipal as well as industrial applications.
• Experience working with a variety of wastewater sources, such as slaughterhouses, dairies, printing, papermaking, and landfill leachate.

Conclusion

There are numerous and diverse wastewater treatment firms with advanced membrane technology, from international technology giants to specialist MBR and UF manufacturers. When considering the characteristics of what each of these has to offer, it is important for the procurement team to consider which one is the most suitable for their wastewater challenge beyond their name.

Before signing a contract with a supplier, keep in mind these qualities of your wastewater, certifications and project references the supplier has, and the production lead time and after-sales support the supplier promises. These things can impact operating expenses and compliance well beyond the installation.

For a supplier that provides patented membrane material choices, an integrated design, manufacturing, and after-sales service, Oxymo Technology would be a good addition to that list. The company’s MBR, MABR, and UF lines, along with experience in producing and installing in more than 40 countries, make it a good choice for those looking to use membrane wastewater treatment for their municipal or industrial applications.

FAQs

What does Oxymo Technology specialize in?

Oxymo Technology’s specialties are MBR and ultrafiltration membranes for municipal and industrial wastewater treatment systems. It makes membranes from various patented material formulations and provides turnkey package treatment plants.

What is membrane bioreactor (MBR) technology?

MBR technology is a combination of biological wastewater treatment and membrane filtration, and the treated water is separated from the solids by a membrane, rather than using a settling tank. This results in more purified wastewater and a lower footprint than traditional methods.

How does advanced membrane technology improve wastewater treatment?

Membrane filtration will remove suspended solids, pathogens, and fine particles, which is not always achieved through conventional treatment, and this ensures that the effluent meets both the discharge and/or reuse requirements. It also enables plants to control varying flows of wastewater in a reduced footprint.

What should businesses look for in a wastewater treatment membrane supplier?

When considering the industry experience, type of membrane material, suitability for your wastewater, ISO certification, lead time, after-sales support, and/or technical support. The cost of the equipment is not the only factor to consider.
