Consider Fenton`s chemistry for wastewater treatment ...

One available ,wastewater treatment, technology that few engineers seem to be familiar with is the ,Fenton, reactor. In this advanced oxidation process, toxic ,wastewater, is reacted with inexpensive ferrous sulfate catalyst and hydrogen peroxide in a simple, nonpressurized (typically batch) reactor to yield (if reacted to completion) carbon dioxide and water.
