UltraPES hollow fiber membrane

Superior in Permeability and Strength!

Our UltraPES™ Polyethersufone (PES) hollow-fiber membrane provides a retentive layer on the inner side of the hollow-fiber membrane.

It exhibits an extremely hydrophilic characteristic which reduces the potential of fouling. In addition UltraPES™ shows a high caustic resistance and free chlorine tolerance allowing Liqui-Flux® modules to operate at pH values between 1 and 13.

Membrana's PES membranes are known for their well defined pore structure. UltraPES™ demonstrates this with its distinctive three layer structure providing a highly porous support for the separation layer giving mechanical strength through thicker polymer ligaments and a protection layer on the outside with reduced pore-size to safeguard the overall membrane structure and integrity.

The pronounced asymmetric structure leads to an outstanding relation of permeability and retention rate. This allows UltraPES™to achieve high volume flow at low transmembrane pressure and provides a unique way to reduce energy costs resulting in low operating costs particularly for larger filtration plants.
