Abstract[English]
The present invention relates to a system and a method for recovering microfibres contained in a liquid effluent (L) from a textile treatment device. The system comprises at least one device (2, 4, 10, 20, 30, 5) for dissolving a gas directly in at least a portion of the liquid effluent (L) by means of pressurisation, and a device (5, 6, 7, 40, 50, 60, 61, 62) for separation by means of dissolved gas flotation, which are connected to one another. The device (5, 6, 7, 40, 50, 60, 61, 62) for separation by means of dissolved gas flotation further comprises means (60, 61, 62) for collecting the microfibres (MF) on the surface of the liquid effluent (L) contained in its enclosure (50).[French]
