<p>The system (1) has a separator unit (17) provided with a filter (32a). A cleaning device (14) includes a circuit for recovering cleaning bodies circulating in an evacuation pipe (12) and another circuit for reinjecting the bodies in an inlet pipe (11). The circuits are used alternately by actuating a set of controlled valves, where the circuits do not convey the bodies to cause fluid i.e. water, to flow in a recovery circuit to collect in the bodies from the inlet pipe or in a reinjection circuit to drive the bodies in the filter towards the inlet pipe.</p> |
