Argonide manufactures a nanofilter based on electropositive capture, versus a "sieve" based filtration process. As a result, its NanoCeram filters are said to attain filtration levels normally associated with ultraporous membranes, without the pressure drop. Even with a pore rating of 0.2 microns, NanoCeram filter cartridges provide flowrates and the low pressure drop of a two micron filter, according to the company.
NanoCeram non-woven, pleated filter cartridges efficiently filter cysts, bacteria, endotoxins, DNA and even virus; and combine a very high dirt-holding capacity with the reliability of a depth filter. NanoCeram excels as a polishing filter and/or as a pre-filter for R.O., ultraviolet, ozone and other treatment systems.
