Product Information
The Sartocool® PS filter cartridge has been specially designed for the sterile filtration of food liquids. We have focused on ensuring microbiological stability with low operating costs to meet the requirements of the food industry.
Applications
Sartocool® PS cartridges are used for final filtration before bottling for drinks such as:
- Wine
- Sparkling wine
- Bottled water
Benefits and features of Sartocool® PS
High Filtration Performance
The extremely large pore volume and density are the decisive reasons for the excellent flow rates of Sartocool® PS. 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 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 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 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 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 has undergone 100 cleaning cycles successfully. Moreover, the properties of Sartocool® PS are not affected by sterilization procedures using hot water or steam. The cartridges also feature excellent stability when subjected to mechanical stress. Sartocool® PS filter cartridges are installed upstream of the bottling machine or keg filler, which necessitates a rugged design. Sartocool® PS meets all these design requirements. As a result, Sartocool® PS cartridge filters can withstand thousands of pressure surges of up to 5 bar (~72 psi).
Microbiological Stability
Sartocool® PS is often connected downstream of the sheet filter to ensure the beer’s shelf life. Sartocool® PS 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.
Integrity-testable and Quality
The integrity of Sartocool® PS membrane filters cartridges can be easily checked by performing an integrity test before and after filtration to guarantee the highest biological safety. This membrane filter is designed and manufactured according to an ISO 9001 certified quality management system. All the raw materials used to produce the Sartocool® PS cartridge comply with the European Union Regulation (EC) No. 1935/2004 as well as the Regulation (EU) No. 10/2011 concerning plastic materials and articles intended to come into contact with foodstuffs.
These guidelines for plastics allow the use in food and beverage applications.
All materials used meet the requirements of the FDA.
