Abstract
An operation support device includes a computation unit that: calculates cost of separation treatment that depends on deterioration of a separation membrane using a cleaning efficiency model expressing deterioration of the separation membrane relative to the number of cleaning events, the separation membrane being configured to remove removal target from sewage; calculates operation cost using the cost of separation treatment, cleaning cost for one cleaning event for the separation membrane, and replacement cost for one replacement event for the separation membrane; determines, based on the operation cost, a first reference value used for determining whether to clean the separation membrane and a second reference value used for determining whether to replace the separation membrane; and calculates cleaning schedule and replacement schedule for the separation membrane using the first reference value and the second reference value determined.
