Beschreibung
Zusammenfassung:	The invention relates to a device for treating (50) an effluent (8) composed of liquid and solid particles such as to obtain a treated effluent, comprising a filtering device (11) using gravity separation on a rotating canvas having an inlet (12) for receiving the effluent (8) to be treated and a first (13) and second (14) outlet, the filtering device (11) being intended for separating the effluent (8) into a first (17) and a second (18) flow, the second flow (18) comprising sludge containing solid particles, the first flow (17) leaving the filtering device (11) through the first outlet (13), the second flow (18) leaving the filtering device (11) through the second outlet (18), and at least one recirculation device (19) for recirculating at least a portion of the sludge from the second flow (18) to the inlet (12) of the filtering device (11), said second outlet being connected to the at least one recirculation device (19). The invention also relates to a method for treating an effluent.
