A bioreactor cleaning system for cleaning a bioreactor in a rail vehicle, comprising a first suction connection, a second suction connection, a flushing connection, an acid tank, a collection tank for receiving liquid drawn out of the bioreactor, a fresh water connection, a pump with a first pump connection and a second pump connection, and a measuring unit for measuring liquid. By means of the pump liquid can be pumped from the first suction connection optionally into the measuring unit, into the collection tank or into the acid tank, aqueous acid solution can be pumped from the acid tank to the second suction connection and/or to the flushing connection; fresh water can be pumped from the fresh water connection selectively to the flushing connection or the measuring unit; and liquid can be pumped from the measuring unit either to the collection tank or to the second suction connection.

Bioreactor cleaning installation for bioreactors in rail vehicles

A method for automated cleaning of a filter basket in a bioreactor includes determining permeability of the filter basket. A control unit controls a suction unit for suctioning a residual liquid from the liquid tank, a liquid metering unit for dispensing a liquid having a predetermined liquid volume into the filter basket controls the suction unit to empty the liquid tank by suctioning a filtered liquid volume, measures the volume of the suctioned liquid volume, and sending a first measurement signal to the control unit. The control unit determines a permeability quotient from the volume of the extracted filtered liquid volume to the volume of the dispensed predetermined liquid volume and compares the permeability quotient with a permeability threshold. The control unit then controls a cleaning unit to perform a cleaning process of the filter basket if the permeability quotient is below the permeability threshold.

Automated permeability test for a filter basket

The invention relates to a suction unit for a wastewater tank, comprising a suction channel extending from a suction adapter designed for attachment to a suction port in the wastewater tank, a connection coupling extending from the suction adapter, wherein said connection coupling and said suction channel are arranged so that the suction channel extends into the wastewater tank, a suction pump connected fluid-tightly to the connection coupling, and a pump control unit in signal communication with the suction pump. A flushing channel extends from a flush adapter designed for attachment to a flushing hole in the wastewater tank, the pump control unit being configured to extract wastewater from the wastewater tank through the suction channel, the connecting line and the suction pump by means of the suction pump, and wastewater is flushed from the wastewater tank through the flushing channel.

Suction device for wastewater tank and disposal station for a vehicle

The invention relates to a sanitary arrangement, in particular, a mobile sanitary arrangement in a motor vehicle such as a coach, having a wastewater-collection tank which has a floor and a sidewall that enclose a tank interior, and an inlet connection and an outlet device. The outlet device has an outlet opening with a connection coupling for the connection of a suction-extraction arrangement and a suction-extraction channel, which, starting from the outlet opening, extends downward in the direction of gravitational force to an intake opening within the wastewater-collection tank.
