Water treatment facility management device, water treatment facility cleaning chemical ordering system, water treatment facility chemical ordering method, and water treatment facility chemical cleaning plan formulation method

摘要

Provided is a management apparatus for a water treatment facility capable of formulating an appropriate cleaning time even if an unsteady situation occurs, and avoiding an excessive inventory of cleaning chemicals. A management apparatus 20 of a water treatment facility using a membrane separation apparatus, which is transmitted via a communication medium from management terminals 11 to 1n that manage operation information of a water treatment system in which the membrane separation apparatus is installed. The water treatment facility information receiving unit 21 that receives the operation information and the cleaning chemical stock information, the transmembrane differential pressure prediction unit 23 that predicts the transition of the transmembrane differential pressure of the water treatment system based on the operation information, and the transmembrane difference A chemical cleaning plan formulation unit 24 that formulates a chemical cleaning plan so that the chemical cleaning is performed before the time when the value or change rate of the transmembrane pressure difference predicted by the pressure prediction unit reaches the set value, and the chemical cleaning plan and cleaning A chemical solution ordering information generating unit 27 that generates chemical solution ordering information based on the chemical solution stock information, a chemical solution ordering information transmitting unit 28 that transmits the chemical solution ordering information generated by the chemical solution ordering information generating unit to an external device including a management terminal, and It is equipped with.
