Ozone for Pesticide Removal

[RBAC]

Sorry this may have been done many times before but...I'm trying to get information on the use of Ozone as a stand alone process for pesticide reduction. The key pesticides are Bentazone and Trietrazine (with levels of 0.17µg/l and 0.10µg/l respectively)

Any experiences or information would be greatly appreciated

I presume you mean pesticide oxidation in this case. Are the compounds in water, soil or both?

Both compounds have moieties susceptible to hydroxyl radical attack, so various advanced oxidation treatment methods will work on them. Direct ozonation alone of these compounds is somewhat iffy, though will probably oxidize these compounds partially without too much difficulty. I would expect the direct ozonation of these compounds in soils or sorbed to solids to be very inefficient to totally ineffective for these compounds, though it might be worth some lab study.
