Sustainable Solutions for Beer Filtration

Clarifying beer involves removing solids and yeast from fermentation and maturation. Pall technologies provide clear beer without impacting taste or foam stability. Solutions vary based on the brewey requirements. Hollow fiber crossflow filtration systems are recommedned for industrial scale beer production while depth filtration solutions are suitable for most micro and craft brewers. 

The Pall PROFi crossflow system is the industry standard for beer filtration and clarification with a patented membrane design and process.

For colloidal beer stabilization Pall provides a solution, the expertise, system and stabilization media for maximum shelf life. Pall’s CBS beer stabilization system is a new technology with immobilized PVPP for a maximum stabilization efficiency and negligible or reduced PVPP losses over long periods.

Microbial beer stabilization or beer “sterile filtration” removes microorganisms which can cause spoilage after packaging. The Pall CFS NEO technology removes these contaminants while maintaining the beer`s flavor and unique characteristics. Compared to pasteurization the CFS NEO system provides higher microbial safety, freshness and taste stability at equal or lower cost.

Colloidal haze and particle filtration including trap filtration are important steps to ensure maximum shelf life and product clarity. Pall’s cartridge solutions aid in removing unwanted particles after primary filtration or as a last critical control point upstream of filling. 

For fine filtration, brewers typically choose sheet-based products like flat sheets, SUPRAdisc™ II modules and SUPRApak™ modules or the Pall depth filter cartridges with different designs, separation rates and safety levels. Craft brewers benefit from tailored solutions by combining different technologies for specific beer styles. For small throughputs below 20 hl/h depth filter combinations replace kieselguhr filters at comparable cost and with superior quality.

Brewers can achieve significant savings by recovering high quality beer from spent yeast. Pall Keraflux™ systems which utilize Membralox®ceramic membranes contribute to an increase in beer yield and extract recovery by separating a maximum of extract from surplus yeast at a high-quality level. This allows direct blend back to process or to a late stage in the brewing process.

Brewers seek maximum yield of extract and hops during the brewing process. Filtration and stabilization contributes to minimizing losses at the individual process steps. Each Pall technology platform is designed to minimize losses during production. System processes fulfil today’s demands for maximum yield without compromising beer quality. 

The impact of beer filterability on brewing costs is well known. Pall technologies can handle beers at different filterability levels without compromising economics and filter life. Intelligent processes, innovative designs and advanced membrane cleaning provide smart solutions for constant and low cost.
