Ozone is a strong oxidant. Typical ozone doses result in 4 :<br />
• Small destruction of TOC<br />
• Increased polarity & decreased aromaticity<br />
• Shift from HMW to LMW<br />
Leads to an increase in the biodegradability of TOC after<br />
ozonation.<br />
Disinfection<br />
• Only enough to inactivate<br />
organisms<br />
• Formation of BOM is undesirable<br />
Reduction of DBPs<br />
• Maximize production of BOM for<br />
removal by biofiltration
