Abstract
A method and an installation for treating a main wastewater stream flowing in a closed conduit with a flow direction. The method includes the steps of: introducing a liquid into at least one pre-treatment stream; generating a gas stream containing ozone gas; introducing the gas stream into the at least one pre-treatment stream, each with a gas injector, resulting in at least one mixed-phase stream comprising ozone laden gas and liquid; passing the at least one mixed-phase stream through at least one static mixer, resulting in a predefined gas bubble size; and injecting the at least one mixed-phase stream in the main wastewater stream perpendicular to the flow direction.
