WATER TREATMENT DEVICE AND OPERATING METHOD FOR WATER TREATMENT DEVICE
摘要
A treatment device is provided with: a separation membrane device having a separation membrane for concentrating dissolved components and dispersed components from water (11) to be treated and obtaining permeating water; a first deposit detecting unit (24A) provided in a non-permeating water branch line (L12) branched from a non-permeating water line (L11) for discharging non-permeating water (15), wherein dissolved components and dispersed components have been concentrated, using part of the non-permeating water that has branched off as detection liquid (15a), and having a first separation membrane (21A) for detection wherein the detection liquid (15a) is separated into permeating water (22) for detection and non-permeating water (23) for detection; and a flow rate measuring device for first separation liquid detection that measures the flow rate of one or both of the permeating water (22) for detection and the non-permeating water (23) for detection separated by the first separation membrane (21A) for detection.
