I have read some interesting papers on wastewater treatment using this 
method (and Fenton's reaction too, but I didn't want to ruin the iron in 
my water column). I just didn't/don't have a UV sterilizer handy, and no 
way to measure hydroxyls if I did. I did have a bottle of peroxide in 
the medicine cabinet though ;)
