DuraPES filtration membrane

The DuraPES filtration membrane has a higher loading capacity than other commercially available membranes. The DuraPES membrane has a unique patent-pending pore structure and dual asymmetric membrane-wall that provides a protected separation layer. This layer has demonstrated its effectiveness in many applications with excellent retention characteristics. The membrane is a hydrophilic sulfonated polyethersulfone (PES) flat-sheet membrane that offers permanent hydrophilicity due to its unique polymer blend and has 80% porosity and a large pore diameter, which provides a high flux rate for superior filtration performance. It also has higher water permeability resulting in increased throughput. The DuraPES membrane is targeted for use in the pharmaceutical and biotech industries for the removal of particles in therapeutics, injectibles and buffer solutions. The food and beverage industry is also a focus area for DuraPES, where it can be used for clarifying and filtering water, beer, wine and juice.
