<p>A desalinization method in which raw water (1) is introduced into a gas/liquid mixing unit (6) and pretreated water obtained thereby is treated in a separation-membrane unit (11), yielding pass-through water and concentrated water. A first sensor (3a) positioned upstream of the gas/liquid mixing unit (6) is used to measure at least one water-quality index for the raw water (1), said water-quality index being selected from the group consisting of hypochlorous-acid concentration, reduction potential, TC concentration, TOC concentration, chlorophyll concentration, oil concentration, turbidity, and chromaticity. The gas/liquid mixing unit (6) is started and stopped and the gas/liquid mixing ratio thereof is controlled in accordance with the measured water-quality index (indices).</p> |
