A dialysis concentrate production system includes a container and a stationary production system. The container comprises a discharge port and a combined port. The stationary production system comprises a storage container comprising a mixing inlet and an outlet, a delivery pump arranged downstream of the outlet, a first water jet pump arranged downstream of the delivery pump, and a second water jet pump arranged downstream of the delivery pump and parallel to the first water jet pump. The first water jet pump comprises a driving inlet in fluid communication with the delivery pump, a suction port in fluid communication with the combined port, and an outlet. The second water jet pump comprises a driving inlet in fluid communication with the delivery pump, a suction port in fluid communication with the discharge port, and an outlet in fluid communication with the mixing inlet.
