Bleach and Chlorine Dioxide ClO2Weak Oxidizer
Volatile at low temperatures (Like Bleach which flashes at a low temperature, 100 Degrees F, Chlorine dioxide flashes at 110 Degrees F)
When free chlorine interacts with proteins environmentally detrimental compounds are such as haloamines, and trihalomethanes, THMs are produced. (THMs are toxic and known carcinogens)
Addition of salts to the water system
Has a negative effect on waste water

Fenton Radox ReactionHydroxyl Radical the second strongest oxidizer know to man.Secondary Fenton chemistry reaction is the generation of peroxide free radical. Fe2+ + H2O2 Fe3+ + OH + OHFe3+ + H2O2 => Fe2+ + H+ + HOO0The peroxide molecule formed in this reaction (HO20) is a powerful peroxide free radical which can also oxidize organic compounds.Engineering

Radox USDA STUDYCase Study 2:Feather Dryer Air Scrubber
100 K SCFM Packed Bed Air Scrubber
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:
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.
