Sartocool® PS Cartridge 0.45 µm 40"

The Sartocool® PS 0.45 μm filter cartridge has been specially designed for the sterile filtration of beer. Its design particulary meets the requirements of the brewing industry; i.e., we have focused on developing an economic process and ensuring microbiological stability. High Filtration Performance: The extremely large pore volume and density are the decisive reasons for the excellent flow rates of Sartocool® PS 0.45 μm. Both the filter area and the pleat geometry are designed for high performance. This has the practical advantage that filter systems can be sized considerably smaller. In part, the number of cartridges installed in existing systems can be greatly reduced, which saves filtration costs. The flow rate of Sartocool® PS 0.45 μm is higher than that for all other membrane cartridges used for this purpose (0.45 μm–0.8 μm). Excellent Throughputs: Filterability of beer is the decisive factor determining the throughput of the cartridges. Nevertheless, the optimized membrane geometry of Sartocool® PS 0.45 μm minimizes the build-up of b glucans, and thus gelation, ensuring excellent throughput. Up to now, cleaning processes using conventional caustic soda, which is available in every brewery, achieved outstanding results. The high throughput of Sartocool® PS 0.45 μm filter cartridges, when used under optimum conditions, will result in filtration costs that are equal to those of flash pasturization. Stability: Since the Sartocool® PS 0.45 μm membrane is made of polyethersulfone, these filter cartridges are chemically resistant within the pH range of 1–14. This means that the cartridges can be regenerated using caustic soda| acids. In practice, Sartocool® PS 0.45 μm have undergone 100 cleaning cycles successfully. Moreover, the properties of Sartocool® PS 0.45 μm are not affected by sterilization procedures using hot water or steam. The cartridges also feature excellent stability when subjected to mechanical stress. Sartocool® PS 0.45 μm filter cartridges are installed upstream of the bottling machine or keg filler, which necessitates a rugged design. Sartocool® PS 0.45 μm meets all these design requirements. As a result, Sartocool® PS 0.45 μm cartridge filters can withstand thousands of pressure surges of up to 5 bar (~72 psi). Microbiological Stability: Sartocool® PS 0.45 μm is often connected downstream of the sheet filter to ensure the beer’s shelf life. Sartocool® PS 0.45 μm offers the highest assurance against beer spoilage microbes, which has been validated by a bacteria challenge test using Lactobacillus lindneri. The retention rate is at least 107 bacteria/cm².

Sartocool PS Food&Beverage Membrane Filter Cartridge

Applications:

The Sartocool® PS 0.45 µm filter cartridge has been specially designed for the sterile filtration of beer. Its design particulary meets the requirements of the brewing industry; i.e., we have focused on developing an economic process and ensuring microbiological stability.

Performance:

The extremely large pore volume and density are the decisive reasons for the excellent flow rates of Sartocool® PS 0.45 µm. Both the filter area and the pleat geometry are designed for high performance. This has the practical advantage that filter systems can be sized considerably smaller. In part, the number of cartridges installed in existing systems can be greatly reduced, which saves filtration costs. The flow rate of Sartocool® PS 0.45 µm is higher than that for all other membrane cartridges used for this purpose (0.45 µm–0.8 µm).

Total Throughput:

Filterability of beer is the decisive factor determining the throughput of the cartridges. Nevertheless, the optimized membrane geometry of Sartocool^® PS 0.45 µm minimizes the build-up of b glucans, and thus gelation, ensuring excellent throughput. Up to now, cleaning processes using conventional caustic soda, which is available in every brewery, achieved outstanding results. The high throughput of Sartocool^® PS 0.45 µm filter cartridges, when used under optimum conditions, will result in filtration costs that are equal to those of flash pasturization.

Stability:

Since the Sartocool® PS 0.45 µm membrane is made of polyethersulfone, these filter cartridges are chemically resistant within the pH range of 1–14.
