Method For Operating Separation Membrane Module, Computer Readable Recording Medium Having Program Recorded Thereon, And Water Production System

Abstract: According to the present invention, in a water production system for obtaining treated water by filtering water to be treated via a separation membrane module, the pressure difference (first resistance R1) between the pressure (P1) of a supply part for water to be treated and the pressure (P3) of a backwash wastewater discharge part in a filtering step, in which water to be treated is filtered from a primary side to a secondary side of the separation membrane module, the pressure difference (second resistance R2) between the pressure (P1) and the pressure (P2) of a treated water discharge part in the filtering step, and the pressure difference (third resistance R3) between the pressure (P1) and the pressure (P3) in a back-pressure washing step, in which pressure is fed from the secondary side to the primary side of the separation membrane module, are calculated, and clogged sections of the separation membrane module are identified using the amount of change or the rate of change from each initial value for the resistances R1-R3 as obtained during said calculations.
