Validation of the EcHsub2/subO Electron-Activated Reactor for Purifying Contaminated Water in Parkersburg (West Virginia)

摘要

This paper discusses validation of the EcHsub2/subO portable i‘batch-treatment’/i electron-activated reactor field unit designed to purify contaminated water to make it safe and potable. The basic EcHsub2/subO system consists of a 90-gallon plastic reactor tank (trash can), ionized nitrogen-oxygen (NI-OXsupTM/sup) vapor-ion plasma generator, and 1-micron electron separation (esup-/supSEPsupTM/sup) porous cartridge water filter. While the NI-OXsupTM/sup generator applies UV radiation to activate and split ambient air into aggressive water treatment agents in the form of free electrons and charged dissolved vapor ions, the esup-/supSEPsupTM/sup cartridge is designed to absorb NI-OXsupTM/sup treatment agents and solvated (free) electrons to induce filtration and rapid disinfection-kill of bacteria and other pathogens. The study started by creating a water quality database from contaminated surface water, EPA/West Virginia water quality standards, and Vienna City water. The EcHsub2/subO purifier was run 14 days/month from April-September 2014 and samples analyzed for chemical and bacteriological quality. When the results were matched against published data, EcHsub2/subO compared favorably with both EPA/West Virginia water quality standards and Vienna City water (iRsup2/sup/i = 0.99; p0.011; N = 13). The EcHsub2/subO purifier was found to be affordable and capable of delivering potable water to households in poor countries at about $0.27 per person per day with economic savings of nearly $7.00 at this rate.
