  • Publication number: 20220356099
    Abstract: A water softening system includes a water feed channel through which water to be treated flows, and a crystallization unit that causes a metal ion contained in the water to be treated to precipitate. Further, the water softening system includes a separation unit that separates the water to be treated having passed through the crystallization unit into a crystal obtained through precipitation by the crystallization unit and soft water. Further, the water feed channel is configured so that at least a part thereof functions as a feed channel being a pressure application system in a substantially sealed state, and the crystallization unit and the separation unit are connected to parts corresponding to the feed channel being a pressure application system in a substantially sealed state in the water feed channel.
