Bioreactor cleaning installation for bioreactors in rail vehicles

A bioreactor cleaning system for cleaning a bioreactor, comprising:

• a first suction connection for connecting to the bioreactor;
• a second suction connection for connecting to the bioreactor, via which a liquid can be suctioned out of a filter basket of the bioreactor;
• a flushing connection for supplying a liquid to a cleaning nozzle of the bioreactor;
• an acid tank for receiving an aqueous acid solution;
• a collection tank for collecting liquid extracted from the bioreactor;
• a fresh water connection for supplying the bioreactor cleaning system with fresh water;
• a pump having a first pump port and a second pump port;
• and
• a measuring unit for measuring liquid;
• whereby by means of the pump:
• liquid can be pumped from the first suction connection selectively into the measuring unit, into the collecting 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.
