BIOREACTOR CLEANING INSTALLATION FOR BIOREACTORS IN RAIL VEHICLES

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.
