1. OXYMO Technology

Email: oxymo@oxymembrane.com

Contact No.: +86 130 0635 3124

OXYMO Technology has built its reputation on one core focus: membrane-based water and wastewater treatment that actually holds up under demanding operating conditions. The company’s specialty is membrane bioreactor (MBR) systems and ultrafiltration systems specifically designed to deliver reliable, long-term water treatment solutions for municipal, industrial, and commercial projects that require consistent performance.

One of the strengths of OXYMO is its depth of manufacturing process, which is far more advanced than many of the newer companies in this field. The company has good control over all production stages, starting from the raw material of the membrane all the way to the finished modules, and between them, to achieve tight quality tolerances. In ultrafiltration, this vertical control is important because even minor structural variations or distribution of pore size in the fibers can shorten the membrane’s life or decrease the flux over time.

OXYMO’s engineering team collaborates with clients during the design process to evaluate feedwater properties and site restrictions before selecting a configuration. This consultative methodology approach has helped cultivate a large customer base of repeat customers in industries where downtime is unacceptable. It maintains quality standards in accordance with international practice and membranes are tested for tensile strength, chemical resistance, and rejection rate before being dispatched; it has a global logistics network that has steadily expanded its presence in the United States.

Key Products and Services

OXYMO’s product line covers the core requirements for membrane bioreactor systems in sewage treatment applications:

• Hollow-fiber MBR membranes in embedded-reinforced PVDF, PVDF, alloy-PVC, PAN, and PS/PES materials, allowing filtration precision to be tailored to treatment needs.
• MBR membranes designed to maintain stable performance even with fluctuating influent loads, a common challenge in municipal sewage systems.
• A membrane-aerated biofilm reactor system that delivers biological treatment while using less energy than conventional aerated systems.
• Ultrafiltration (UF) membrane systems, including a gravity UF series for lower-energy filtration
• Membrane distillation technology for advanced separation and water recovery applications
• End-to-end design, manufacture, installation, and commissioning of OXYMO package sewage treatment plants

Industries Served

OXYMO serves municipal water utilities, industrial parks, food and beverage processors, textile manufacturers, chemical processing plants, and commercial developments pursuing onsite water reuse — giving its engineering team exposure to a wide range of feedwater profiles.

What Makes OXYMO Technology Stand Out?

• In-house manufacturing control from raw material to finished module to reduce quality variability
• Pressurized or submerged MBR configurations, offering flexibility depending on site conditions
• Custom engineering assistance for feedwater analysis, system sizing, and layout planning
• Skid-mounted and mostly pre-assembled systems that minimize on-site installation time and labor costs
• Membrane testing for tensile strength, chemical resistance, and rejection rate prior to shipping
• Competitive pricing attractive to both mid-size and large-scale projects.
• Responsive technical support for cleaning protocols, fouling management, and troubleshooting
• Export experience supporting distributors and project developers across international markets, including the USA

These advantages make OXYMO Technology a strong contender when comparing ultrafiltration membrane manufacturers for new or upgraded water treatment projects.

How to Choose the Right Manufacturer for Your Project

Comparing ultrafiltration membrane manufacturers on paper is only the first step. Let’s take a look at the practical considerations that will help you make your decision.

1. Manufacturing experience — Years of manufacturing experience usually mean fewer design flaws to work through.
2. Certifications and quality standards — check for ISO or NSF certification in your field of work.
3. Product quality and testing — ask for rejection rates, flux and chemical resistance.
4. Customization capability — a supplier who is able to modify the configuration to your feedwater gets better results
5. Production capacity — ensure the manufacturer has the capacity to meet your volume and deadlines.
6. MOQ (Minimum Order Quantity): Make sure to inquire about MOQ upfront if you are a smaller contractor or distributor.
7. Lead time — obtain realistic production and shipping dates, particularly fixed dates of commissioning
8. Experience in exporting — documentation experience decreases customs delays for imported equipment
9. Technical support — confirm what troubleshooting assistance is available after installation, not just during it.
10. Pricing structure — compare total cost of ownership, not just the upfront quote
11. Warranty terms — understand what is covered, because the warranty of the membrane and components may differ
12. Communication and after-sales service — responsiveness in communication is often a preview of after-sales service.
