More Information
Summary:The present invention relates to a method of lowering high concentration of strong oxidants such as halogens in oxidation state 0 or higher, peroxides, organic peroxides, persulphates or ozone in wastewater from aquaculture using an agent selected from sulphur dioxide and easily dissolvable salts of reduced oxyanions of sulphur, in combination with UV light treatment. In one embodiment, the method of the invention relates to neutralizing high concentration of hydrogen peroxide (H2O2) in aquaculture delousing wastewater using an agent mentioned above in combination with UV light treatment.
