PROBLEM TO BE SOLVED: To provide a water desalination system having an abnormality detection function capable of early detecting an abnormality of equipment in the water desalination system.SOLUTION: A water desalination system 100 comprises a water desalination plant 2 and an abnormality detection apparatus 1 which detects abnormality of the plant 2. The water desalination plant 2 includes: a high pressure pump 202 which pressurizes water to be treated; a reverse osmosis membrane module 205 which separates pressurized water to be treated into fresh water in which salt content in the pressurized water to be treated has been removed and concentrated water in which salt content in the pressurized water to be treated has been concentrated; and a power recovery apparatus 203 which recovers energy from the concentrated water. The abnormality detection apparatus 1 includes: a performance index calculation part 101 which calculates a performance index of each equipment in the plant 2 based on any two or more of measured values among at least measured values of flow rate, pressure, temperature and water quality of water to be treated, concentrated water and fresh water; a category classification part 102 which classifies operation data into a plurality of categories based on the characteristics of the operation data; a determination part 103 which determines normality/abnormality of each equipment based on classified categories; and a display part which displays a plurality of countermeasure methods for equipment which has been determined to be abnormal, according to the predetermined order of priority. |
