ErtelAlsop The First Name in Liquid Filtration ZetaDri-Pak The ZetaDri-Pak® is a lenticular disc cartridge that offers the benefits of depth filtration in addition to capturing free and emulsified water from your product. The depth filter Pak® cartridge invented by ErtelAlsop more than 50 years ago allows for easy change out, low labor costs, along with optimizing filtration area and cake space. The 16 cell ZetaDri-Pak® holds a minimum of 148 ounces of water and allows the operator to simply monitor the differential pressure to determine when the filter Paks® need to be changed. The ZetaDri-Pak® is used for various applications where water is a problem. From Flavorings to Oils, the ZetaDriPak® will solve the problems water causes. The ZetaDriPak® will give you the retention level you require and will remove water from your product positively. Composition ErtelAlsop ZetaDri-Paks are composed of cellulose pulp, Diatomaceous Earth and/or Perlite and a wet strength resin, which charge modifies the media to exhibit a net positive charge zeta potential. This allows for the highly efficient removal of particles smaller than the filter’s nominal rating. Applications: • • • • • • Food & Beverage Flavorings Cleaning Fluids Fragrances & Oils Chemicals Fuels Product Testing Product testing is always available either at your facility, through our network of distributors, or at our in-house laboratory.
