Sanford, FL, March 20, 2007 – Argonide Corporation has brought its latest development forward with new advances in nano engineered technology (“NET”). Built on NanoCeram^®, their patented electropositive non-woven filter media, the Sanford-based company has created another breakthrough.  Now nano powders can be incorporated into a non-woven web, much like paper. The nano powders can be a photocatalyst such as titanium dioxide, an oxidation catalyst such as platinum, a sorbent such as fumed silica, and even a biological particle such as DNA. 

The first innovation of the new technology uses powdered activated carbon (PAC).  Laboratory testing with flowing streams of iodine show that it has extraordinary dynamic adsorption capacity.  As compared to other carbon-containing media, the volume of iodine adsorbed until it becomes detectable by taste or odor is about 180 times as great.  Granular activated carbon (GAC) is typically used in standard filters which contain carbon, but it is widely recognized that GAC is not as dynamically effective as PAC. Unfortunately, PAC can’t be retained in a non-woven media without the use of foams, binders or adhesives, that tend to deactivate and/or foul the carbon.  Argonide’s new technology circumvents this difficulty. 

The next step was to incorporate other, smaller particles in lieu of the PAC. Fumed silica, only 10 nanometers in size, was successfully integrated into the non-woven structure; this was followed by nano titanium dioxide, then a catalyst, then RNA. According to Fred Tepper, President of Argonide, “NanoCeram-NET™ allows nano powders in the non-woven structure to be more interactive with the fluid in which the media is suspended, and without affecting the surface properties of the nanomaterial itself”. As a result, this new technology would enhance the performance of nano powders in their intended function. Once the technology reaches beyond the laboratory stage, such new media could be custom manufactured by a wet laying process. 

NanoCeram^® filter media is licensed to Ahlstrom Corporation and is sold under the name Disruptor™. Test samples of experimental non-woven media could be produced to custom order at Argonide. Should the application prove practical, and scale-up is required, then the client can expect that such a variation of NanoCeram-NET™ can be produced by Ahlstrom at high volumes and at a reasonable cost.
