The suction is generated by the Siemens side channel turbine, the suctioned products are collected in a recovery container within which a metal container allows separating the solid part from the liquid one. Solid particles up to 150 microns can be filtered if provided with a filter.

When the recovery container is full, a level switch automatically stops suction, the filtered liquid is discharged by means of a lever that reverses the direction of flow, allowing the recovery of the filtered liquid in the tank.
