Abstract: Water-softening device (1) of the present disclosure includes water-softening tank (4) that performs a water-softening treatment on raw water containing a hardness component with weakly acidic cation exchange resin (9) to generate acidic soft water, neutralization tank (5) that neutralizes a pH of the acidic soft water generated by passing through water-softening tank (4) with weakly basic anion exchange resin (10) to generate neutralized soft water, soft water detector (6) that detects an electrical conductivity of the neutralized soft water generated by passing through neutralization tank (5), acquisition unit (17) that acquires a first electrical conductivity corresponding to an ion other than the hardness component in the raw water, correction unit (18) that corrects the electrical conductivity of the neutralized soft water based on the first electrical conductivity acquired by acquisition unit (17) to output a second electrical conductivity, and calculator (19) that calculates hardness component informat

Abstract: Water softening device (1) of the present disclosure includes water softening tank (3), neutralization tank (4), electrolytic tank (12), water pump (19), current value detector (18), and controller (17) that controls a regeneration treatment. In the regeneration treatment, controller (17) continues the regeneration treatment when a current value of water pump (19) detected by current value detector (18) is more than or equal to a predetermined value, and stops the regeneration treatment and shifts to a hardness component discharge treatment of discharging a hardness component in the water softening device to the outside of the water softening device when the current value of water pump (19) detected by current value detector (18) is less than the predetermined value.

Abstract: The provided materials are a grid load interactive control method and terminal based on adaptive load characteristics and a storage medium. The method includes: receiving a test presetting message sent by a master station and sending message reply information to the master station; parsing the test presetting message to obtain a test presetting instruction; building a test environment and generating a virtual action exit in the test environment when the test presetting instruction generates a record; and sending instruction response including the record to the master station so as to cause the master station to determine whether a test is successful according to the record.
