Title:
METHOD FOR PREPARING WATER QUALITY PROFILE, METHOD FOR INSPECTING SEPARATION MEMBRANE MODULE, AND WATER TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/071507
Kind Code:
A1
Abstract:
The present invention provides a method for preparing a water quality profile that has (1) a step 1 for supplying water to be treated to a separation membrane module with a supply port for the water being treated and multiple permeate outlets and obtaining permeate, (2) a step 2 for varying the ratio of the flow rates of the respective permeates flowing out of the multiple permeate outlets, (3) a step 3 after step 2 for measuring the respective water qualities of the permeates, and (4) a step 4 for plotting the relationship between the ratio of the respective permeate flow rates varied in step 2 and the respective water qualities of the permeates measured in step 3 as a scatter diagram, steps 2-4 being repeated multiple times.
