The NanoCeram® Superfilter is the result of a NASA small business contract to purify recycled water for long duration space flight.  In Phase I of the contract, awarded in October 2001, Argonide corporation developed the filter and showed it was feasible for sterilizing water.  In September 2002 the company was  awarded Phase II where they focused on a number of issues, including increasing the size of the filter and determining methods for renewing the filter. In 2007 the technology was finally proven effective and manufacturing was begun. LivingWaters™ Engineered Water Treatment Solutions was one of the first companies to adopt this technology for use in domestic drinking water devices.

The NanoCeram® family of pleated filter cartridges are far more than just another sediment filter. They are designed to satisfy the most difficult needs in water treatment.

When used in multiple layers as with our LivingWaters™ products that incorporate our SafeWater™ Technology, NanoCeram® filter media is capable of retaining 99.9999% of micro-organisms (such as viruses, bacteria & protozoa which can include Cryptosporidium, Giardia Intestinalis, Legionella, Pseudomonas, Salmonella, E-coli, Mycobacteria, Aspergillus), endotoxins & DNA - all at flow rates hundreds of times greater than virus-rated ultrafiltration membranes.  And the turbidity of the water coming through the NanoCeram media typically remains below 0.01 NTU (even when tested at 250 NTU) until the filter is exhausted.

When assembled into a robust family of standard-size filter cartridges, NanoCeram®. delivers results that conventional separation technologies simply can't. Utilizing our patented electropositive filter technology, this cutting-edge purification process makes conventional treatment products obsolete by delivering a sustained, precise, consistent, cost-effective and highly efficient filtration process in a simple and easy to handle filter cartridge.

NanoCeram® filters utilize a highly electropositive filter media that rapidly adsorbs particles, no matter how small. As a result, each NanoCeram electropositive water filter has a high capacity for particles as large as tens of microns or as small as a few nanometers (submicron and colloidal). Such is the nature of electropositive attraction that even with an average pore size of 2 - 3 microns the NanoCeram® Filter Cartridge exhibits an Absolute Rating of 0.2 microns; an Absolute Rating typically associated with ultraporous membranes. Yet NanoCeram® flow rates are hundreds of times greater than such membranes.

The advantage of this technology is that it is an adsorptive removal process using a media that makes available greater than 42,000 square meters of nanofiber surface area per square meter of filter media of loading capacity.

Sub-micron particles tend to be electronegative owing to the double layer affect. At a pH of 7.2, electronegative particles are attracted by the high zeta potential (~50 mv) between the media and the particle or hydrocarbon droplet. The electropositive charge extends up to 1 micron from each nanoalumina fiber to effectively cover the entire 2 micron average pore space of the media. The media does mechanically retain particles >0.5 μm, but the electropositive charge is most effective on particles <0.5 μm.

Such is the nature of electropositive attraction that even with an average pore size of 2 - 3 microns the NanoCeram® Filter Cartridge exhibits an Absolute Rating of 0.2 microns.
