A method of operating a water treatment system (1), having - a softening device (4), in particular comprising an ion-exchange resin (7), - a conductivity sensor (9), - and electronic control device (13), and - an automatically adjustable blending device for mixing a blended water stream V(t)blend from a first, softened part-stream V(t)part1 soft and a second, raw-water-carrying part-stream V(t)part2raw, is characterised in that the conductivity LF soft of the softened water or the conductivity LF blend of the blended water is determined experimentally, and in that the conductivity LF raw of the raw water and/or the total hardness of the raw water is derived from the experimentally determined conductivity LF soft of the softened water or LF blend of the blended water. With the invention, inexpensive and permanently reliable control of a water treatment system, in particular of the regeneration and blending, is possible. |
