Easy UF Replacement

Replacing ultrafiltration membranes doesn’t have to be complex or costly. NX Filtration offers open-source UF membranes designed specifically for straightforward replacement in existing installations — with minimal downtime and maximum operational reliability.

Easy Replacement of your UF membrane modules
Designed for easy replacement
Our NX Ultra membranes are compatible with a wide range of commonly used, standard UF modules on the market. This makes replacement simple, cost-effective and fast — without major system modifications.
An ideal solution for utilities and industries looking to extend asset life while improving performance.

Lower OPEX through smart membrane design
The inside-out configuration protects the separation layer and enables efficient cleaning and maintenance. Combined with our robust modified PES chemistry, this results in:
- reduced fouling
- fewer cleanings
- longer membrane lifetime

Outcome: lower operational costs and stable, long-term performance.

Want to know if your current UF can be replaced?
Use our UF replacement tool or download the brochure for technical details — or contact our specialists for a best-fit recommendation, even if a 1-to-1 replacement is not available.
