Ozonation

Ozone is produced by passing dry compressed air through two concentric electrodes having a dielectric charge in between them. A high voltage is applied between both the electrodes to produce a Corona Discharge. As the feed air is passed through the high voltage electric field, a portion of oxygen of the air gets converted to Ozone. Ozone is light blue in colour with a distinctive pungent odour. The system is totally automatic and maintenance free with no refilling or replacement or recurring costs.

Ozone is twice as powerful an oxidant as chlorine. The oxygen (O2) in the air forms O3 which is highly reactive and unstable. Ozone does not add any ionic contamination because it degrades to O2. Ozone must be dosed into water on a continuous basis because it has a very short half-life (approximately 20 minutes at ambient temperatures) in solution. In certain applications all ozone must be removed prior to end use. This may be achieved by exposing the ozonated water to ultraviolet light which breaks down the ozone to oxygen.
