Filtration achieved by the separation process between water and the suspended waste particles. Water flows out of the filter cartridge where waste are kept.

When the mesh filter becomes clogged, it produces a difference in pressure between the inlet and the outlet manifold. The solenoide valve activates the hydraulic control system by opening a flushing valve.
The water flows through the nozzles located in the scanner and is expelled through the turbine. This way the water drags the waste from the mesh and makes the scanner rotate which cleans the mesh.

The cleaning process can also be started manually.
