Abstract
It is an object of the present invention to provide a method of estimating the maximum value of the flux during long-term stable operation including cleaning of a membrane filtration plant based on measured data of a membrane filtration characteristic during initial membrane filtration. The present invention provides a method in which the maximum flux during stable operation of a new membrane filtration plant for which a membrane module and operating conditions have been specified is estimated from a measured value A of an initial membrane filtration characteristic measured using a liquid to be treated in and a membrane of a membrane module of the new membrane filtration plant, an empirical value of a maximum flux during stable operation of each of a plurality of existing membrane filtration plants having the same or a similar membrane module and operating conditions, and a measured value B of the initial membrane filtration characteristic measured using a liquid to be treated in and a membrane of a membrane module of each of the existing membrane filtration plants.
