Ultrafiltration
Our solution for RO pre-treatment, potable water production, wastewater treatment, and food and beverage applications.
Our ultrafiltration (NX Ultra) membranes are designed not only for exceptional performance but also for straightforward replacement, ensuring minimal downtime and operational efficiency.
Manufactured using modified polyethersulfone (PES) chemistry, NX Ultra membranes offer excellent chlorine tolerance and pH stability, supporting reliable operation under demanding conditions. Their inside-out configuration can be operated in semi dead-end or cross-flow mode, providing flexibility to control fouling and optimise system performance.
Whether for drinking water production, industrial filtration, or wastewater reuse, our NX Ultra membranes stand out for their efficiency and low environmental impact. Explore how NX Filtration’s advanced technology redefines water treatment—bringing you cleaner water and a greener tomorrow.

Easy Replacement with NX Ultra Modules
At NX Filtration, we understand the importance of seamless integration and reliable operation in water treatment systems. NX Ultra (UF) membranes combine proven performance with straightforward replacement, helping customers minimise downtime and maintain operational efficiency.
NX Ultra modules are compatible with a wide range of commonly used standard UF systems, making membrane replacement simple and cost-effective. The inside-out configuration enables efficient cleaning and maintenance, while our robust modified PES chemistry provides excellent resistance to fouling and chemical exposure, supporting consistent long-term performance.
Whether replacing membranes in an existing installation or upgrading system performance, our team provides tailored support to identify the right NX Ultra solution for your specific application.
Key benefits and differentiators
Modified PES Membrane: NX Ultra membranes are manufactured using modified polyethersulfone (PES), providing excellent chemical stability, chlorine tolerance and compatibility across a wide pH range of 2–12.
Energy Efficiency: The membrane design can operate without air scour, helping reduce energy consumption and improve overall process efficiency.
Certified Excellence: NX Ultra membranes meet internationally recognised standards and certifications, including KIWA, KTW, NSF, ACS and ISO.
Superior Pathogen Rejection: Certified rejection performance of up to 4-log viruses and 6-log bacteria supports demanding drinking water applications.
PFAS-Free Membrane Chemistry: NX Ultra membranes are manufactured using PFAS-free PES chemistry, supporting customers in responding to evolving requirements around PFAS-containing materials.
Enhanced Filtration Efficiency: A narrow pore size distribution provides consistent filtration performance and high-quality effluent across a wide range of applications.
Maximum Fibre Protection: The inside-out configuration protects the membrane’s separating layer from external influences, reducing the risk of fibre damage and supporting a long operational lifetime.
Comprehensive Retrofit Programme: NX Filtration provides expert support for replacing membranes in existing UF systems, enabling customers to upgrade performance without replacing the complete installation, thereby minimising downtime and investment.
