A water treatment plant which performs water treatment using a water treatment device includes an imaging device, a processing device, and a control device. The imaging device images a water treatment environment of the water treatment device and outputs image data obtained by imaging. The processing device causes an arithmetic device which performs an arithmetic operation using one or more calculation models generated by machine learning to execute the arithmetic operation employing the image data output from the imaging device as input data of the one or more calculation models. The control device controls the water treatment device on the basis of output information output from the arithmetic device by executing the arithmetic operation.

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.
