Title:
SEPARATION MEMBRANE DIAGNOSIS METHOD, WATER PROCESSING METHOD, SEPARATION MEMBRANE DIAGNOSIS DEVICE, WATER PROCESSING DEVICE AND SEPARATION MEMBRANE DIAGNOSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/135235
Kind Code:
A1
Abstract:
Provided are a separation membrane diagnosis method, a water processing method, a separation membrane diagnosis device, a water processing device, a separation membrane diagnosis program, and a storage medium on which the program is stored, with which the cost of water processing can be reduced by accurately ascertaining the state of a separation member used in water processing. The separate membrane diagnosis method includes: an acquisition step for acquiring an indicator expressing the state of a separation membrane that performs solid-liquid separation; a change-over-time recording step for recording the change over time of the acquired indicator; an oscillation analysis step for analyzing the oscillations of the recorded change over time; and a determination step for determining the water permeability state of the separation membrane on the basis of the analyzed oscillations.
