Title:
METHOD FOR OPERATING A WATER SOFTENING SYSTEM COMPRISING TARGET VALUE CONTROL BY A WATER REMOVAL STATION
Document Type and Number:
WIPO Patent Application WO/2010/099910
Kind Code:
A3
Abstract:
A method for operating a water softening system (1) comprising an automatically adjustable blending device (9a, 9a', 9a") for mixing a blended water flow V(t)blend from a first, softened partial flow V(t)part1softened and a second partial flow V(t)part2untreated conducting untreated water, and comprising an electronic control device (11), the control device (11) regulating the adjustment position of the blending device (9a, 9a', 9a") by means of one or more experimentally determined instantaneous measured quantities such that the water hardness in the blended water flow V(t)blend is set to a predefined target 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 target value (SW) is predefined by a setting of the one or more water removal stations (50, 50', 50") and the setting of the one or more water removal stations (50, 50', 50") is communicated to the control device (11). The present invention enables a water softening system to supply water having different degrees of hardness to one or more water removal stations connected thereto in a convenient manner.
