摘要： Water softening device includes water softening tank and neutralizing tank. Water softening tank softens raw water containing a hardness component by weakly acidic cation exchange resin. Water softening tank includes first water softening tank and second water softening tank. Neutralizing tank neutralizes the pH of softened water that has passed through water softening tank by weakly basic anion exchange resin. Neutralizing tank includes first neutralizing tank and second neutralizing tank. Water softening device is configured to cause raw water containing a hardness component to flow through first water softening tank, first neutralizing tank, second water softening tank, and second neutralizing tank in this order.
