Ozone/hydrogen peroxide

The common oxidants are ozone, hydrogen peroxide, H2O, catalyzed usually with ferrous iron, Fe , and ia some cases chlorine dioxide and uv light. Advanced oxidation systems iaclude H2O2 + uv ozone + uv and H2O2, ozone, and uv. Depending on the appHcation, the oxidation can be complete to end products as in a contaminated groundwater or partial to degradable intermediate products as in a process wastewater. 

Oxidation. Oxidation is one of the main chemical methods to treat and decompose dyes in wastewater. The oxidation agents used ate chlorine, bleach, ozone, hydrogen peroxide, Fenton s reagent, and potassium permanganate.

At the U.S. Department of Energy s (DOE s) Kansas City Plant in Kansas City, Missouri, a Ultrox UV/ozone/hydrogen peroxide system was used to treat up to 38 liters/min of groundwater contaminated with tetrachloroethene (PCE). The capital costs were estimated at 380,000. Operation and maintenance costs were estimated to be 5/m of water treated (D19079Y, pp. 3-5).
