7A-3. Micro-Flocculation and Oxidation
Ozone oxidizes the following metals (know as
micro-flocculation), enabling their removal via
filtration:
• Iron
• Copper
• Manganese
• Zinc
• Arsenic
Ozone neutralizes "nuisance" compounds - most
commonly, hydrogen sulfide.
7A-4. Factors Affecting Sanitation
The following factors will affect the ability of ozone
to effectively act as a sanitizer:
• Type and level of contaminant
• Physical/chemical parameters of the environs
• Exposure time
• Temperature
• Concentration
• Water chemistry and pH
• Cleanliness
• Microbial attachment
