Model Bevpor PS -Microbiological Stabilization and Sterilization Filter Elements

The filter medium consists of a naturally hydrophilic polyethersulfone (PES) membrane. This is particularly suitable for filtering water, aqueous solutions and chemicals in the entire pH range.

Compared to conventional filter membranes made of nylon, PVDF, polysulfone (PS) or cellulose, BEVPOR filter elements are characterized by higher throughput , longer service life and higher mechanical and thermal stability.

Due to the high chemical compatibility with acids, alkalis, oxidizing agents and other organic chemicals, BEVPOR filter elements can be easily reactivated or sterilized even with aggressive and/or oxidative chemicals (e.g. chlorine dioxide).

When filtering clear fruit juices, beer, soft drinks, wine or protein solutions, the PES membrane shows only a very low adsorption of dyes and protective colloids. The filter therefore does not change the taste or color of the product.

The BEVPOR filter series was specially developed for critical applications that require long filter service lives . By using exclusively hydrophilic construction materials, BEVPOR filter elements are very easy to wet.

Microbiological stabilization and sterilization

• Validated microbiological separation rate of 0.1 to 1.2 microns
• Easily wettable and easy to test for integrity
• Inert filter medium without adsorption of proteins, colors and flavors
• Fractionated separation performance due to the asymmetric membrane structure
• Regenerable, CIP-capable and steam-sterilizable
• BEVPOR PH also with integrated pre-filter layer
