NanoCeram-LR high-performance pleated filter cartridges (photo) have been specifically designed and engineered as drop-in replacements for lenticular filters. They will fit most commercial lenticular housings, and are said to show greater dirt-holding capacity, higher efficiency and wider operating pH range versus other charged lenticular filters. Each NCLR incorporates the patented non-woven filter media matrix infused with nano-alumina fibers, creating an electropositively charged depth filter. NanoCeram is capable of removing small particles (including colloidal iron), bacteria and viruses from water at high flowrates. Silt density index (SDI) values averaging less than 0.5 and turbidity levels less than 0.01 NTU are achieved . — Argonide Corp., Sanford, Fla.
