Over the last decade or so, a new genre of nano-sized ultra-high-surface-area catalyst particles have been developed to high degrees of efficacy. When added to polluted water (employed in-solution e.g. in-situ), these new catalysts have been shown to effect extremely rapid, complete and inexpensive catalytic destruction (chemical breakdown to benign species) of a host of approximately 50 recalcitrant, ubiquitous, and carcinogenic groundwater pollutants on the EPA-'Hotlist'. These include but are not limited to chlorinated lower alkanes, alkenes and aromatics (including PCE, TCE, cis, trans, and 1,1 DCE, and vinyl chloride, and all chlorination states of benzene and other aromatics), several THMs, DDT, Lidane, PCBs, Dioxins, TNT, NDMA, Organic Dyes, dichromates, perchlorate, a large host of pharmaceutical residuals, and other recalcitrant trace pollutants of immediate concern in our groundwater. The desire to use these highly effective catalysts for various large-scale GWR applications has been a natural consequence, but catalytic nanoparticles themselves are toxic, so their in-situ use necessitates that they in turn be completely removed from the treated water prior to it’s use. Because these particles are so small (and numerous), very robust (e.g. High-performance R.O.) operations are required to accomplish such removal, rendering the overall remediation operation much too expensive for large scale groundwater (or other) remediation operations.
The new High Efficiency Nano-Catalyst Immobilization (HENCI) technology uniquely meets all the above criteria, and as such is the last piece in the puzzle for unleashing the true power of nanocatalysis to remediate our groundwaters. As such, HENCI is poised to usher in a new era in nano- and micro-catalysis marked by a leap in efficacy of dilute-reactant applications such as groundwater remediation. Detailed HENCI technology capability information, live demonstration videos, and ancillory information (including presentations to the NWRI and other agencies) is availible at www.henci.com
