New Technology Uses Plasma to Purify Water
Added Aug 5, 2013 | Rate View top rated
John Foster, an associate professor of nuclear engineering and radiological sciences at the University of Michigan, is working on a method to purify water with the fourth state of matter - plasma. Foster hopes his new technology, which produces reactive radicals that can attack organic contaminants such as pesticides and pharmaceuticals, will help solve a problem not currently being addressed in conventional treatment methods that rely on filtration and chlorine. Originally envisioned as a point-of-use system for underdeveloped countries, this new technology could be scaled up to a larger mechanism that would be implemented as a stage in the conventional treatment process.

Doesn't this use the same principle as the familiar Ozone purification process? Just wondering what the advantages are here.

Couldn't we fabricate arrays of electrodes (using semiconductor microstructure chip fabs), much like the dipoles in phased-array radars, to generate the plasma in running water? Wouldn't such electrodes generating plasma in water (and UV light), when exposed over a TiO2 surface (immersed in the water), create significantly higher levels of radicals in-situ than just plasma without TiO2?
