Title:
OPERATION-ASSISTING DEVICE AND OPERATION ASSISTANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2019/244718
Kind Code:
A1
Abstract:
This operation-assisting device (100A) is provided with a calculation unit 1 that: calculates the separation treatment cost corresponding to the deterioration of a separation membrane, which removes substances to be removed from water being treated, using a cleaning efficiency model (D5) that represents the deterioration of the separation membrane with each cleaning cycle; calculates the operation cost, which is a sum of the separation treatment cost, the separation membrane cleaning cost, and the separation membrane replacement cost for a separation membrane operation period using the separation treatment cost, the cost per cleaning cycle of the separation membrane, and the cost for a single replacement of the separation membrane; determines, on the basis of the operation cost, a first reference value to be used for determining whether or not to clean the separation membrane and a second reference value to be used for determining whether or not to replace the separation membrane; and using the determined first reference value and second reference value, calculates when to clean and when to replace the separation membrane.
