<p>PROBLEM TO BE SOLVED: To provide a fresh water generation system and a fresh water generator, capable of suppressing biofouling by injecting chloramine, while suppressing deterioration of a semi-permeable membrane, in order to achieve biofouling suppression and RO film deterioration prevention simultaneously and economically.SOLUTION: In a fresh water generation method, water to be treated containing at least either of bromide ion and iodide ion is treated by a semi-permeable membrane treating device. In the fresh water generation method, before treating the water to be treated by the semi-permeable membrane, chloramine and a pH adjustment agent are added into the water to be treated.</p> |
