Sterile Filtration for Beer | Pall Corporation

Sterile filtration of beer is the final and most critical step in ensuring long shelf life, microbiological safety, and flavor stability. Our advanced membrane systems deliver the best sterile filtration for beer, removing yeast, bacteria, and particles without compromising freshness.

What Is Final Filtration in Beer Production?

Final filtration is how breweries achieve sterile beer without pasteurization. Using cold membrane filtration, brewers remove spoilage organisms while preserving taste and aroma—making it the preferred method for sterile filtration of beer.

Why Choose Membrane Filtration Over Pasteurization?

Compared to pasteurization, membrane-based beer sterile filtration offers better microbial removal, no thermal impact, and lower operational costs. It’s the best choice for brewers seeking shelf-stable, cold-filtered beer with uncompromised flavor.

Sterile Filtration vs. Pasteurization: Why Membrane Wins

Sterile filtration of beer offers superior microbial removal compared to pasteurization. While pasteurization inactivates spoilage organisms, membrane filtration physically removes yeast and bacteria—resulting in cleaner, fresher beer.

Key Benefits of Pall’s Sterile Filtration Systems

Superior microbial removal: Physically separates yeast and bacteria for cleaner beer
Flavor preservation: Cold filtration avoids thermal damage to taste and aroma
Integrity testing: Filters are tested before and after each batch for traceability
Cost efficiency: Lower energy use and maintenance compared to pasteurization
Long service life: Cartridges withstand repeated hot water and steam sterilization
High throughput: Optimized pleat design ensures reliable performance

Advanced Design for Breweries

Pall offers two leading solutions for sterile filtration of beer:

CFS NEO System

A fully automated membrane filtration system designed for cold, sterile beer filtration. It ensures consistent microbial safety, reduced energy consumption, and simplified operation.

PAREQII Filter Cartridges

Hydrophilic membrane filters qualified for removing spoilage microorganisms. Built for repeated hot water sanitization and steam sterilization, they offer long service life and high throughput.
