The invention relates to a system (18) for treating waste water containing at least one cosmetic product, which system (18) can be placed in an application space (12) for applying cosmetic product on a user. The system (18) comprises: a tank (36) for holding and separating the waste water; an inlet (38) for moving untreated waste water into the holding tank (36); a bubble generator (32) capable of feeding an amount of bubbles into the waste water of the holding tank (36) so as to produce treated water in a lower region (50) of the holding tank (36) and a supernatant in an upper region (52) of the holding tank (36); a lower outlet (40) for recovering treated water from the holding tank (36); and an upper outlet (42) for discharging a foamy supernatant from the holding tank (36). The system (18) is devoid of means for injecting a compound for flocculating and/or coagulating the waste water at least upstream from the holding tank (36). The invention also comprises an application arrangement (10; 110) for applying cosmetic product on a user, including the aforementioned system (18), and a method for treating waste water containing at least one cosmetic product.
