Japanese Patent JP6667282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control method of a water purification system that can supply speedily and safely a desired amount of water when a treatment water quantity of a water purification system varies.SOLUTION: A control method of a water purification system provided with a membrane filtration apparatus set to be operated in the range of a predetermined treatment water quantity in an operation state where a membrane filtration operation is performed includes a step of determining necessary number of the membrane filtration apparatuses based on a total quantity of clear water necessary for the water purification system and the range of the treatment water quantity of the membrane filtration apparatus, a step of grasping the number of the membrane filtration apparatuses operable among a plurality of membrane filtration apparatuses and comparing the necessary number and the number of the operable membrane filtration apparatuses, and a step of, based on the result of the comparison, making the necessary number of the membrane filtration apparatuses in an operation state when the number of the operable membrane filtration apparatuses is equal to or larger than the number of the necessary apparatuses, and by making the membrane filtration apparatuses of the operable number in an operation state when the number of the operable apparatuses is smaller than the number of necessary apparatuses, and the apparatus is operated at a setting value of the maximum treatment water quantity.SELECTED DRAWING: Figure 2
