USDA Compared ClO2 to RADOX-
23 Fenton Treatment System
Gas chromatography ("GC") and
mass spectrometry ("MS") was
used to determine destruction
efficiency
Results From USDA Study:Results From USDA Study:
“Samples from Radox-treated air streams had (1) 42 % higher
concentration of carbon dioxide (CO2); (2) 69 % lower
concentrations of the highly aldehyde compounds, and (3) 52 %
lower total VOC when compared to untreated, or ClO2-treated
samples.”
“The RADOX treatment reduced the total perceived odor intensity
by 74 while the ClO2 treatment did not significantly alter the odor
intensity.“
"The RADOX catalyst was shown to be significantly more
effective than chlorine dioxide (ClO2) for reducing the
concentration of malodorous VOC and total VOC emitted from
poultry rendering.
“The concentration of highly malodorous aldehyde compounds,
which were responsible for a majority of the poultry rendering
odor, were not changed by the ClO2 treatment.”
“Additionally, there was a 5-fold higher concentration of indole in
the ClO2 samples when compared to RADOX-treated samples.”
