Document Type and Number:
Japanese Patent JP2019022870
Kind Code:
A
Abstract:
To provide a water treatment device which can clean a plurality of film modules at an appropriate timing.SOLUTION: A water treatment device includes: a plurality of film modules arranged in parallel with each other; a pump which sends raw water to the plurality of film modules under pressure; a first pressure gauge which can measure a supply pressure of the raw water to be supplied to at least one film module; a second pressure gauge which can measure a discharge pressure of filtrate water that has penetrated through the plurality of film modules; a detection control section which detects a difference pressure between the discharge pressure and the supply pressure from a measurement value of the second pressure gauge and a measurement value of the first pressure gauge; and a cleaning mechanism which cleans the plurality of film modules based on the difference pressure.SELECTED DRAWING: Figure 1
