METHOD OF OPERATING MEMBRANE FILTRATION SYSTEM

PROBLEM TO BE SOLVED: To provide a membrane filtration system which can operate stably for a long time by forecasting operating conditions through evaluating a membrane module for evaluation, in conjunction with a membrane filtering method for obtaining permeant water by filtering, through a membrane, water to be treated such as underground water, river water, lake/marsh water, sewage water to be secondarily treated. SOLUTION: This membrane filtering system is equipped with a precise filtration membrane and/or ultrafiltration membrane, as well as the membrane module for valuation which evaluates the same water to be treated as in the case with the membrane filtration system body by accelerated velocity test. The method of operating the membrane filtration system is to optimize the operating conditions of the membrane filtration system body, considering the ascending degree of filtration resistance of the membrane module for evaluation.
