摘要： PROBLEM TO BE SOLVED: To provide a city water softening device capable of economically realizing a rational soft water supply. SOLUTION: Supply for softening and supply for raw water are performed by using a water softening tank 1 for softening the city water and a bypass piping 20 by selectively using three-way solenoid valves 12 and 18, and the ion exchange capacity of an ion exchange resin particle layer 2 is recovered by supplying regeneration salt water to the water softening tank 1 at the time of raw water supply.

摘要： PROBLEM TO BE SOLVED: To enable the repetition of stable generation of regeneration salt water by breaking a bridge formed by solidifying dissolved residual salt without depending on the water permeability of the residual salt. SOLUTION: A breakage supporting member 80 for a salt bridge is erected on a shelf 76 for placing salt. The shelf 76 for placing salt is installed in a state of floating above the bottom inside a container 71 of a generation tank 29 for regeneration salt water and forming a space 77 below the shelf. The water for generating regeneration salt water is supplied to the space and is brought into contact with the salt placed on the shelf for placing salt. The regeneration salt water is generated and supplied to a water softening tank 1. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent a water-softening tank from being given big water impulse due to intermission of water supply. SOLUTION: This city water softening water supplier is provided with a water supply solenoid valve 8 for supplying city water to a water-softening tank section 1b, a pressure tank section 1a for storing softened water flowing out of the water-softening tank and a pressure sensor 4 which detects water pressure in the pressure tank and performs opening/closing control of the water supply solenoid valve so that water pressure in the pressure tank is in a prescribed range.

摘要： PROBLEM TO BE SOLVED: To facilitate the installment of a new city water softening apparatus and the transfer of an existing city water softening apparatus. SOLUTION: A part of soft water supplied from a water softening tank 1 is diverted. The diverted soft water is supplied as water for producing reclaimed saline water to a reclaimed saline water producing water storage tank 31 through a stored reclamation water flow rate control means 34. The water for producing reclaimed saline water stored in the tank 31 is supplied to a reclaimed saline water production tank 26 through a manual reclamation water supply valve 32, and reclaimed saline water which passed through the water softening tank 1 is stored in a drain storage tank 17 and discarded.
