Abstract

A seawater desalination plant system comprises a plant portion producing fresh water from seawater and supplying fresh water to consumers via a water distribution pool (20). In a seawater desalination plant system, a seawater quality prediction means (32) predicts quality of seawater for each predetermined time during a certain definite period based on a past actual measurement value of quality of seawater. In addition, an optimum plan calculation means creates a plurality of proposed plans of fresh water production quantity during the definite period in which fresh water production quantity required for the definite period is allotted to the each predetermined time, calculates, with respect to these, an electric power consumption rate for desalination using the seawater quality predicted for the each predetermined time, the fresh water production quantity, and a previously obtained recovery rate, and obtains an optimum fresh water production quantity plan from the plurality of proposed plans of fresh water production quantity based on this. A display means (36) displays the content of this obtained optimum fresh water production quantity plan.

[0001] [Citation to related application]

[0002] This application is based on Japanese Patent Application No. 2011-200922 (filing date: September 14, 2011), and enjoys priority benefits from this application. This application incorporates the entire contents of the above-mentioned application by referring to the above-mentioned application. technical field

[0003] Embodiments of the present invention relate to a seawater desalination plant system that produces fresh water from seawater and supplies the produced fresh water to consumers via a water distribution tank. Background technique

[0004] In recent years, seawater desalination plants for producing drinking water from seawater have been adopted as one of the countermeasures against water scarcity. Seawater desalination plants supply seawater to reverse osmosis membranes, filter seawater through reverse osmosis membranes to produce fresh water, and supply the produced fresh water to consumers through distribution tan...
