Food and pharmaceutical production water have strict microbial control standards. Ordinary PVDF UF membrane easily breeds microorganisms inside fiber cavities during static shutdown. Our PAN alloy internal pressure ultrafiltration element adopts permanent hydrophilic fiber formula with fiber breakage rate controlled below three per thousand, no long-term flux decay after repeated hot water and food-grade weak acid cleaning. It efficiently intercepts coliform bacteria and macromolecular organics, supplying sterile low-turbidity inlet water for LF-ULP and LF-BW food-grade RO membrane. All raw materials comply with FDA food contact standards with no toxic precipitation during long continuous operation.
All PAN internal pressure UF membrane and matched food-grade RO membrane models are sorted in our water filter element.
