FAULT DETERMINATION PROGRAM AND FAULT DETERMINATION DEVICE FOR FRESH WATER GENERATION SYSTEMS, AND RECORDING MEDIUM

Provided is a computer-readable recording medium having recorded therein a fault determination program for fresh water generation systems, the program causing a computer, for determining a fault taking place in a fresh water generation system which repeats a filtration step for passing to-be-treated water through a separation membrane and a physical cleaning step for physically cleaning the separation membrane via a plurality of processes, to function as: a means for inputting operation data for the filtration step and the physical cleaning step; a means for recording the operation data; a means for selecting the filtration step or physical cleaning step in which fault is to be determined; a processing rule recording means in which a processing rule for the operation data are preliminarilyrecorded; a means for obtaining processing data by processing the operation data recorded in the operation data recording means, on the basis of the processing rules for the step selected by the stepselection means; a settin
