Electropositive Pleated Media Helps Remove Bacteria
Argonide Corp. has launched its NanoCeram-HF high-performance pleated filter cartridges specifically engineered and designed to address the bio-contaminant issues in most water-treatment applications. This pleated filter cartridge utilizes a design whereby a pleated layer of electropositive filter media is wrapped around a 0.15 um Absolute hollow fiber membrane. This design can yield extremely high filtration efficiency for virus, bacteria and cysts.
Each NanoCeram-HF filter cartridge contains a pleated layer of Argonide's non-woven filter media matrix, which is infused with nanoalumina fibers, creating an electropositively-charged depth filter. In this configuration, a NanoCeram filter can produce water with ultra-low SDI (silt density index) values, which is crucial for protecting membranes from fouling.
When used to protect the hollow-fiber membranes, which are rated to retain > 99.999999% (>log 8) of all bacteria including Legionella and cysts, a NanoCeram‐HF filter is designed to offer an ultra‐high level of filtration efficiency enabled by hollow fibers and the high-efficiency reduction levels associated with NanoCeram technology, according to Argonide. This filter will provide initial bacteria (E coli) and cyst retention greater than 8 LRV and greater than 4 LRV virus (MS2) retention.
In addition, NanoCeram is capable of removing small particles (including colloidal iron and TOC's), from water at high flow rates, using this same principal of electrostatic attraction and adsorption. These cartridges are now available and will fit into most commercially available 2.5" x 10" filter housings. All components in NanoCeram-HF filters are FDA-compliant and appropriate for food contact.
