B2

Provided is a water treatment apparatus that can reduce the amount of chemical solution addition. A water treatment apparatus is provided with a decarbonation apparatus, a first adjustment section, a first water softening apparatus, a second adjustment section, and a reverse osmosis membrane apparatus. The decarbonation apparatus removes the dissolved carbonic acid component in water being treated. The first adjustment section adjusts the water being treated from which the dissolved carbonic acid component has been removed, to around neutrality. The first water softening apparatus softens the water being treated which has been adjusted to around neutrality. The second adjustment section adjusts the softened water being treated to alkaline. Using a reverse osmosis membrane, the reverse osmosis membrane apparatus separates the alkalized water being treated into concentrated water and permeated water.
