Advanced Oxidation for Waste Destruction:
Magic or Simple Chemistry?
Industrial waste treatment is
demanding new solutions. DI tanks are a great revenue source
for the providers, but a growing maintenance headache for end
users. Regenerating resin is costly, labor intensive and does
not limit the waste liability. Merely transferring the
contaminant from one medium to another is no longer acceptable.
More and more companies want to
eliminate the waste on-site. This need has taken oxidation and
advanced oxidation approaches and pushed them to commercially
viable options. Wastech now introduces the
SIGMA Advanced Oxidation family.
Simple Chemical Oxidation
Simple chemical oxidation uses a
strong oxidizer (such as hypochlorite, peroxides, persulfates,
percholorates, permanganates, etc.) to break down hazardous
waste into less toxic constituents. The net result of these
chemical reactions is to convert the pollutant to its basic
minerals. This means converting the substance to either carbon
dioxide gas or water and a mineral salt. Take Hydrogen Peroxide,
for instance, and its ability to control slime, to remove FOG
and chlorine residuals, and to oxidize sulfides, metals and
other easy to oxidize components of BOD/COD.
More resistant substances or more
difficult to oxidize pollutants may require a catalyst to boost
the reactions.
Advanced Oxidation Technologies (AOT)
What is advanced oxidation
technologies (referred to as AOT)? AOT produces hydroxyl
radicals (-OH), which are highly reactive oxidizing agents that
will react with and destroy most dissolved organic contaminants
in water. Organics and inorganics can be destroyed. This would
include chlorinated solvents (methylene chloride, carbon
tetrachloride), benzene, toluene, alcohols (IPA, ethanol),
glycols, and generic organics (as measured by COD, BOD and TOC).
 The hydroxyl radical is formed
when hydrogen peroxide is combined with UV light and ozone as a
catalyst. Wastech Controls has a family of solutions for various
combinations of hydrogen peroxide, ozone and UV. The Wastech
SIGMA family is a modular unit with a UV reaction chamber, ozone
generator, H2O2
injection and complete automated controls. Modules can be
combined for higher flow rates. These automatic systems will
solve those difficult waste treatment problems.
If you are
hauling waste or your DI costs are skyrocketing, look at
Wastech’s SIGMA Advanced Oxidation for on-site destruction.
