Ultrafiltration

Ultrafiltration (UF) membranes are used in a wide range of applications, varying from RO-pretreatment, potable water production, and waste water treatment. NX Filtration provides UF membranes for new and existing systems. UF membranes typically have pore sizes between 5 and 50 nm. This make them the go-to choice for the removal of particles, bacteria, and viruses from different water sources. Our UF membranes are based on modified PES chemistry resulting in excellent chlorine tolerance and pH stability. The membranes are operated in “inside-out”, typically in a semi dead-end mode, providing perfect control of the membrane fouling rate.

Ultrafiltration replacement

NX Filtration provides direct UF replacement for various modules manufactured by Pentair X-Flow (previously part of Norit). Modules with identical dimensions, for plug and play replacement, are available for XIGA 40, AquaFlex 40, Seaflex 40 and the Seaguard 40 models with S225 FSFC or SXL225 FSFC model numbers. 

Not only can the NX Filtration MexFil™ UF replacement modules replace existing elements, our UF075 membranes are characterised by a high permeability and a superior rejection of bacteria and viruses compared to membranes with a 150 kDa or 250 kDa molecular weight cutt-off. 

Contact our sales department for pricing and delivery options of replacement modules. 

UF075

The NX Filtration MexFil™ UF replacement modules are available with a superior 75 kDa Molecular Weight Cut-Off membrane with a narrow 15 nm nominal pore size distribution. This membrane combines  a high permeability with improved removal of bacteria and viruses. The small pore size results in reduced pore blocking, which improves backwash effectiveness.  As a result the UF systems will deliver a more stable permeate flow rate, also on high fouling feed waters.
