SECTION 5 OVERVIEW AND SAFETY PROCEDURES
5A.i Relative Strength of Ozone
The following compares the strengths of several common oxi-
dizing reagents (EOP vs. Cl2)
• Elemental Fluorine (2.25)
• Hydroxyl Radical (2.05)
• Ozone (1.52)
• Hydrogen Peroxide (1.30)
• Hypochlorite (1.10)
• Chlorine (1.00)
• Chlorine Dioxide (0.93)
• Bromine (0.57)
5A.ii Micro-Flocculation and Oxidation
Ozone oxidizes the following metals (known as micro-floccula-
tion), enabling their removal via filtration:
• Iron
• Copper
• Manganese
• Zinc
• Arsenic
Ozone neutralizes “nuisance” compounds - most commonly,
hydrogen sulfide.
