The new generation of ultrafiltration membranes is produced by Polymem a French manufacturer of modules for water filtration, and made from a specific innovative Kynar® PVDF resin from Arkema, a global leader in fluoropolymers. This material demonstrates outstanding long-term resistance to oxidants and exceptional mechanical strength in a microporous structure. The water to be treated passes through the microporous fibers, similar to hollow spaghetti under one millimeter in diameter, to be ultra-filtered with the scale of the pores in the 10 to 20 nanometers range.

Repeated, long-term cleanability is a key feature of these membranes. Moreover, due to the long-lasting hydrophilic property of the membranes, filtration throughput is high while cleaning frequency is between 20 and 30% lower than with other polymer materials.
