Ozone Strong Water

Water purification process through oxidation


Ozone Strong Water consists of water purification through highly efficient advanced oxidation with ozone, ensuring micropollutant and toxicity elimination.

The technology can be applied to all water and wastewater treatment plants (WWTPs) in which advanced oxidation is needed to ensure clean and safe water. The method aims to remove micropollutants such as personal care and pharmaceutical contaminants (including hormones, antiobiotics) and decrease wastewater toxicity. By replacing the traditional ozone gas injection by the injection of ultra ozonated water, the sizing and capital expenditure of the reaction chamber are reduced significantly. Ozone Strong Water eliminates the pollutants and allows its users to economically treat wastewater. The solution has been through extensive tests to validate its efficacy not only in micropollutants itself but its toxicity as well. Hard COD (chemical oxygen demand) removal, discoloration, and disinfection are some of the applications for Ozone Strong Water.
