ABSTRACT:
The invention concerns a water treatment method including a step of clarification, followed by an ozonization step and at least one filtration step, wherein after the clarification step (1), one fraction of the main stream of water is diverted (9); said diverted fraction of water is circulated counter-current (7) to an ozone-rich carrier gas, and the ozone-enriched fraction of water is diluted in the main stream.
