As the beverage industry becomes more competitive, manufacturers need to filter more of their valuable liquid, such as beer or wine, through their filters more quickly without changing the media. To save time, instead of changing spent media, you can simply back-flush your system and continue your process, or process a different liquid, using our new Backwashable Zeta Pak®.
ErtelAlsop’s Backwashable Zeta-Pak® lenticular module cartridge filter features a protective polypropylene honeycomb scrim covering on each cell layer of the module/ cartridge. These protective covers provide strength and support for the media against back pressure, and allow for backwashing of the filter, several times over. This design has become critical for our customers, as they realize they can get several extra filtration cycles with the same media when using our Backwashable Zeta-Paks®. Customers are also able to filter up to 30% more liquid using our Backwashable Paks® vs. other brands of backflushing modules.
ErtelAlsop manufactures a wide range of lenticular cartridge configurations. The Backwashable Zeta-Pak®, modules/ cartridges are available in two diameters, 12 inches and 16 inches, with a varied number of cells. Surface areas range from 3 ft2 to 36 ft2.
The Backwashable Zeta-Pak® lenticular filter module has an all polypropylene structure for improved cartridge integrity.
ErtelAlsop also manufactures in house a complete line of filter housings for lenticular cartridges, including vertical and horizontal Pak® design housings to fit your application. Available materials include carbon steel, 304, 316, or 316L stainless steel, Hastelloy®, and polypropylene or fiberglass reinforced polypropylene. ErtelAlsop offers customized designs for your specific application processing requirements.
