Advanced Oxidation System
The Pollution Control Systems Oxidation process destroys
dissolved organic contaminants in contaminated water.
In these processes, a proprietary high-powered, medium
pressure lamp emits high energy UV radiation through
a quartz sleeve into the contaminated water. Oxidizing
agents, Hydrogen peroxide and Ozone are added to the
contaminated water and is activated by the UV light
to form oxidizing species called hydroxyl radicals,
via:
UV/O3/H2O2 + UV.....> 3(.OH)
The hydroxyl radical reacts with the dissolved contaminants,
initiating a rapid cascade of oxidation reactions that
ultimately fully oxidize (mineralizes) the contaminants.
The success of the system is based on the fact the rate
constants for the reaction of
.OH radicals with most organic pollutants are very
high.
The hydroxyl radical typically reacts a million to
a billion times faster than chemical oxidants such a
ozone and hydrogen peroxide. In addition many organics
contaminants undergo a change in the chemical structure
by the direct absorption of UV light in the UV-C spectral
range emitted by proprietary medium pressure UV lamps
