Arkema to supply Kynar FSF PVDF materials for development of advanced hollow fiber ultrafiltration membranes under partnership with Polymem and water treatment specialist Tergys; partnership capitalizes on durability, chemical resistance of the materials

For many years, 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.
