Ozone has been used in water treatment for a long time to get rid of contaminants and to reduce micro-pollutants in drinking water and for treating industrial wastewater with a high chemical oxygen demand (COD) as found in the textile, pharmaceutical and specialty chemicals industries.
Recently, more and more countries have been introducing regulations for the residual micro-pollutants in treated wastewater after conventional municipal biological treatment. Various advanced oxygenation process treatment trains have been tested for this purpose, and ozone has been proven to be very effective in dealing with these compounds.
In the corona-discharge production process, ozone is created by an electrical discharge to ambient air or oxygen. When using highly concentrated or pure oxygen instead of ambient air for the production of ozone, the following advantages arise
- Higher ozone production
- Smaller footprint
- No pre-treatment of the feed gas is required
