Minimising the cost of microbiological stabilisation per unit volume whilst maintaining quality and product characteristics is a key requirement within beverage production. BEVPOR PW is an advanced membrane filter cartridge designed to meet and surpass these criteria. Specifically developed for the microbiological stabilisation of bottled water, BEVPOR PW utilises an advanced polyethersulphone membrane and integral prefilter layer to give high flow rates, long life and improved throughput. The combination of prefilter and the asymmetrical pore structure of the membrane provides graded filtration through the depth of the media, resulting in increased capacity to hold contaminants. Componentry has been selected to withstand repeated chemical cleaning and steam sterilisation.
