Ozone is a form of oxygen(O2) with the molecular formula O3. It forms when oxygen in the air is exposed to the discharge of a powerful electric current through air. In nature, it forms in the upper atmosphere when lightning passes through the air. The pungent odor often associated with passage of a thunder storm which leads some to exclaim how “clean” the atmosphere smells, is attributed to naturally formed ozone. Ozone is unstable and changes to O2 shortly after its formation. It is a powerful oxidant and one of the most powerful disinfectants available in water treatment.
Ozone applications Drinking water
Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water treatment. Ozone can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation or final disinfection. Usually, it is recommended to use ozone for pre-oxidation, before a sand filter or an active carbon filter (GAC). After ozonization these filters can remove the remaining organic matter (important for final disinfection).
This combination has several benefits:
- Removal of organic and inorganic matter
- Removal of micro-pollutants, such as pesticides
- Enhancement of the flocculation/coagulation-decantation process
- Enhanced disinfection and reduction of disinfection byproducts
- Odor and taste elimination
