SURFACE WATER TREATMENT

residual ozone destruction

Ozone treated drinking water can contain small quantities of residual ozone that may be released into the atmosphere in certain water treatment plant stages, e.g. mix tanks, filters, etc. OxyPureTM hydrogen peroxide can be added to ensure destruction of residual ozone and minimize ozone release.

H₂O₂ + O₃ ----> 2 ^. OH + ³/₂O₂ ----> H₂O + 2 O₂

For 1 mg/L ozone, 1.4 mg/L 50% OxyPure^TM must be added.

Advantages

Fast reaction rate
Low capital
Easily administered
Low operation and maintenance
Increased oxidation power
