AI Technical Summary

Technical Problem

Existing water treatment facilities suffer from resource waste and energy consumption during dialysis treatment, especially due to the lack of flexibility in filter maintenance, which leads to unnecessary maintenance processes and resource waste.

Method used

The water treatment facility with a control unit can switch between treatment and maintenance modes. It detects the filter's working capacity through sensor data and performs maintenance only when necessary. The control unit automatically plans the appropriate time window for the maintenance process, avoiding unnecessary maintenance.

Benefits of technology

This enables efficient and flexible operation of water treatment facilities, reduces resource waste and energy consumption, and ensures the continuity and efficiency of dialysis treatment.

Abstract

The invention relates to a water treatment system for producing a medical solution, in particular dialysis water, which can be operated in a first operating mode and in a second operating mode, comprising a control unit, characterized in that the control unit is programmed to control the medical solution, in particular dialysis water, in the first operating mode. Preferably on the basis of the sensor data, it is detected whether the water treatment plant and / or at least one component thereof needs to be operated in the second operating mode, and if it is detected that the water treatment plant needs to be operated in the second operating mode, it is determined whether it is possible to switch from the first operating mode to the second operating mode at the current point in time, if the determination shows that the switching to the second operating mode can be carried out at the current time point, a control command is output to the water treatment plant and / or at least one component thereof in order to operate the water treatment plant and / or at least one component thereof in the second operating mode. If the determination shows that the switching to the second operating mode cannot be performed at the current time point, a future time point is determined, at which the control unit outputs control commands to the feed water treatment system and / or at least one component thereof, and the switching to the second operating mode cannot be performed at the current time point. In this way, the water treatment plant and / or at least one component thereof is operated in a second operating mode.
