Document Type and Number:
Japanese Patent JP2019018191
Kind Code:
A
Abstract:
To provide an apparatus and method for membrane filtration treatment capable of controlling permeation flux of a membrane within an appropriate range according to a nature variation at the occurrence thereof, and of optimizing the operating conditions of the apparatus.SOLUTION: An apparatus for membrane filtration treatment includes control means 5 which controls at least one of the difference pressure between separation membranes and the membrane surface flow rate according to an estimated value of permeation flux of a membrane calculated by using actual measurement values which become controlling factors of nature variation of a water to be treated permeating through the separation membrane.SELECTED DRAWING: Figure 1
