Food and pharmaceutical industries have strict sterile requirements for process water, and ordinary PVDF UF membrane is easy to breed microorganisms inside the fiber under dead-end filtration state. Our PAN alloy internal pressure UF membrane adopts permanent hydrophilic fiber formula, no flux attenuation after long-term hot water and food-grade weak acid cleaning, the fiber breakage rate is controlled below three per thousand, and the interception effect of coliform and microbial spores is stable. It is specially matched with food-grade ULP and BW RO membrane as sterile pretreatment, can remove macromolecular organic matter and bacteria in raw water, provide low-turbidity qualified inlet water for food and pharmaceutical reverse osmosis systems, and ensure the produced pure water meets food safety and medical sterile standards. All raw materials comply with FDA food contact regulations, no toxic precipitation during long-term operation.
Complete PAN internal pressure UF membrane and matched food-grade RO membrane models are sorted in our water filter element series.

Core PAN UF Membrane Performance Advantages
1. Permanent hydrophilic alloy fiber, no flux decline after repeated hot water cleaning
2. Ultra-low fiber breakage rate less than 3‰, stable long-term operation
3. Support dead-end and cross-flow two optional operation modes
4. Easy to clean with food-grade weak acid and hot water without organic residue
5. Small module size, compact structure suitable for small food water equipment
6. Perfect matching with food-grade LF-ULP / LF-BW RO membrane
Full PAN Internal Pressure UF Complete Model List
LF-UF-4021, LF-UF-4040, LF-UF-160B, LF-UF-8040
Food production lines must use PAN internal pressure UF membrane to cooperate with food-grade RO membrane, avoid secondary microbial pollution of production water caused by ordinary membrane materials. We can provide complete food-grade dual-membrane matching schemes and material certification documents for global food processing customers.
