METHOD FOR OPERATING A WATER SOFTENING SYSTEM COMPRISING TARGET VALUE CONTROL BY A WATER REMOVAL STATION

摘要

A method for operating a water softening plant (1) having: an automatically adjustable blending device (9a, 9a, 9a) for mixing a blended water flow V(t)blended comprising a first softened partial flow V(t)part1soft and a second partial flow V(t)part2untreated which carries untreated water, and having an electronic control device (11), the control device (11) controlling the adjustment position of the blending device (9a, 9a, 9a) by means of one or more experimentally determined current measurement variables in such a manner that the water hardness in the blended water flow V(t)blended is adjusted to a predetermined desired value (SW), the blending device (9a, 9a, 9a) supplying one or more water removal stations (50, 50, 50) with blended water, is characterized in that the desired value (SW) is predetermined by a setting of the one or more water removal stations (50, 50, 50), and in that the setting of the one or more water removal stations (50, 50, 50) is transmitted to the control device (11). With the present invention, it is possible to provide water having different levels of hardness at one or more connected water removal stations with a water softening plant in a convenient manner.
