Ahlstrom, a leader in high performance fiber-based materials, introduces a new nonwoven product, Disruptor PAC, for the filtration of water. The nanoalumina fiber technology used in the product is licensed exclusively from the Argonide Corporation.

This technology can economically improve the purity and taste of nearly any water stream by efficiently removing a large variety of contaminants including virus, bacteria and humic compounds.

Humic compounds are naturally occurring, ultrafine particulate organic compounds, about the size of a virus, produced by the decay of natural organic matter found in surface waters.

Prior to Disruptor PAC, humic compounds were not able to be completely removed by microfiltration or ultrafiltration polymeric membranes.

Disruptor PAC contains powdered activated carbon having an average particle size of only 8 microns. The small particle size produces remarkably high dynamic adsorption as compared to conventional granular carbon or carbon blocks.

With Disruptor PAC, the retention of the powdered activated carbon is accomplished through electro kinetic adsorption by the nanoalumina fibers in the product, not with binders or adhesives.

This retention mechanism makes nearly all the pores of the powdered activated carbon available for adsorption of chlorine, iodine, volatile organic compounds, disinfection byproducts and natural organic material from water.

Ahlstrom believes that the unique features of Disruptor PAC will provide filter and filtration device manufacturers with the ability to design more efficient and cost effective products to improve the quality of both drinking water and waste water.
