Arkema and French membrane producer Polymem, recently acquired by US life sciences company Repligen Corporation, have been partners in the development of Neophil advanced hollow fiber ultrafiltration membranes based upon Arkema’s Kynar FSF PVDF.

These fibers are well known for their tremendous durability in terms of physical strength and chemical resistance. They are tailored to offer extremely long-lasting permeability and long-term repeated cleanability.

Both companies collaborated with Tergys, a manufacturer of autonomous water treatment systems powered by solar panels and rechargeable batteries to develop containerized solutions that enable drinking water production from off graded water. These filtration systems are ideally suited for deployment in remote and disaster-stricken regions, where filtration capacity can range from just a few cubic meters to several hundred cubic meters.

The Kynar FSF PVDF based membranes are compliant with demanding French Sanitary standards ACS and ensure effective and durable filtration of contaminants in the scale of tens of nanometers allowing the efficient in-situ production of safe drinking water.

"Arkema and Polymem have had a long and successful relationship on water ultrafiltration thanks to Neophyl® membranes manufactured with Kynar® PVDF. We are proud to collaborate with Tergys on this exciting innovation that enables safe access to drinking water in isolated territories.”
