Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating seawater capable of the size decrease and cost reduction of a seawater treatment apparatus and enhancement of the life of a separation membrane, and to provide the water treatment apparatus. SOLUTION: The method for treating seawater has a TEP removing step of removing a TEP (Transparent Exopolymer Particles) component from seawater, and a first membrane separation step of treating the seawater by membrane separation after the TEP removing step. The TEP removing step preferably has the step of adding magnetic particles to the seawater, the step of adhering the magnetic particles to the TEP component contained in the seawater, and the step of separating the TEP component adhered to the magnetic particles from the seawater by a magnetic separation part.
