摘要： A brine tank (100), a method to provide brine for regenerating an ion-exchange material and a water softening method are described. The brine tank (100) comprises a first compartment or top area (103) containing a solid salt, a second compartment or bottom area (102) for storing brine, and a separation element (101) between the two compartments. The separation element (101) contains openings which allow water and brine to pass therethrough but prevent passage of the solid salt. The brine tank further comprises an inlet (105) to feed water into the tank, an outlet (105) to discharge brine from the tank, and a water level control device (not shown) and/or at least one volume meter configured to measure the volume of brine discharged from the tank and/or the volume of water fed into the tank. The water level control device and/or the at least one volume meter are configured to adjust a water level in the tank that allows a portion of the salt contained in the first compartment to be in contact with water fed into the tank such that salt is caused to dissolve in the water and form brine. The first compartment, the second compartment and the separation element are arranged such that the brine formed in the first compartment (103) is able to sink through the openings of the separation element (101) into the second compartment (102). The second compartment is connected to the first compartment by a return line (106) through which brine is to be transferred from the second compartment (102) into the first compartment (103), thereby establishing a brine circulation that results in a much faster dissolution of solid salt in the first compartment. In addition to this, it is possible to chlorinate the brine with the help of an electrolyzer cell (107) positioned in the return line (106). The described water softening method comprises a regeneration step in which the brine generated in the brine tank is used.

摘要： A water softening device (100; 200) comprises a filter (101; 201) which is configured to remove hardness from a first stream of raw water to produce a second stream of softened water. The filter (101; 201) comprises an ion exchange (IEX) material which is loaded with a first cationic ion species deriving from a tracer salt and with a second cationic ion species deriving from a regenerant salt. The IEX material shows a lower affinity to the first cationic ion species than to the hardness. At the same time the IEX material shows a higher affinity to the first cationic ion species than to the second cationic species. An electrical property of the second stream is monitored by a sensor (112; 212). A change in the monitored electrical property can be used as an indicator for the exhaustion state of the filter (101; 201).

摘要： A water softening device (100) comprises a filter (105) which is configured to decrease hardness of a first stream of raw water to produce a second stream of water with decreased hardness, a first sensor (109) for measuring an electrical property of the first stream and a second sensor (110) for measuring an electrical property of the second stream. The sensors are able to measure an electrical property of the first stream and an electrical property of the second stream. The ratio of the measured properties can be used as an indicator to estimate the exhaustion state of the filter.
