- the preparation device may also itself comprise such a suction device. This is suitably designed and arranged in the treatment device, a negative pressure downstream of the at least one first
- the suction can have at its output an interface for contacting an external sewer, which opens, for example, in a vehicle external waste water tank.
- the suction device may be arranged between the cleaning openings and the interface, so that it generates a negative pressure in a line section of the suction line between the first cleaning opening and / or between the second cleaning opening on the one hand and the suction device on the other hand for suction of the inlet and / or outlet.
- the evacuated content can be further transported with overpressure through the suction line to its outlet.
- Both the at least one first cleaning drain in the inlet area and also the at least one further, second cleaning drain in the outlet area are fluidically connected to one and the same suction line. Both cleaning drains open in this embodiment example in a common suction line, which is connectable to a suction device.
- the suction line has at least one shut-off device downstream of the at least one first cleaning outflow and / or the at least one further, second cleaning outflow.
