Mixing systems for ready-to-use flush solutions

Mixing system for ready-to-use flush solutions, the mixing system comprising:

• an RO system (2), a mixing unit (5) that is connected to the RO system (2) and contains a mixing chamber (47), to which high-purity water can be fed from the RO system (2) and flush solution concentrate can be fed from a concentrate source (55), and a flush solution link connector (63), wherein the RO system (2) and the mixing unit (5) form a filling station (95), and
• a mobile flush solution container (6) comprising a transport carriage (70) and a pressurized container (97) arranged on the transport carriage, the pressurized container receiving a flush solution bag (69) that can be coupled to the flush solution link connector (63) of the mixing unit (5), and a computer and control mechanism (80) for all measurement and monitoring tasks during the local production of a flush solution,
• wherein the transport carriage and the filling station (95) are provided with sensors by means of which wireless communication is made possible between the transport carriage and the filling station (95), wherein a park or docking position of the transport carriage at the filling station is given by the sensors.
