COMPUTER-READABLE RECORDING MEDIUM ON WHICH CLOGGING LOCATION SPECIFICATION PROGRAM FOR SEPARATION MEMBRANE MODULE IS RECORDED, WATER PRODUCTION SYSTEM, AND WATER PRODUCTION METHOD

The present invention provides: a water production system in which water to be treated is filtered with a separation membrane module to obtain treated water, wherein a clogging location is specified by calculating a pressure difference between the primary-side inlet side and outlet side of the separation membrane module in a step for supplying the water to be treated to the primary side of the separation membrane module, a pressure difference between the primary side and the secondary side of the separation membrane module in a filtration step for pumping the water to be treated from the primary side to the secondary side of the separation membrane module, and a pressure difference between the secondary side and the primary side of the separation membrane module in a back-pressure washingstep for causing water to pass through the separation membrane module from the secondary side to the primary side thereof; a water production method; and a computer readable recording medium on whicha clogging location specif
