According to one embodiment, a water treatment control apparatus generates an indication to a water treatment facility referring to conditions including a drought status and a water treatment cost at the water treatment facility. The indication indicates a type of water to be taken by the water treatment facility between a plurality of types of water including river water from rivers, rainwater, and waste water used by a customer.

Water treatment control apparatus and water treatment system

A treated water quality control system (,) has a sewage inflow estimating unit (,) for estimating an inflow of sewage and a process data storage unit (,) for storing process data on a sewage treatment plant (,). An estimated sewage inflow estimated by the sewage inflow estimating unit (,) and process data read from the process data storage unit (,) are given to a manipulated variable calculating unit (,). The manipulated variable calculating unit (,) calculates values of manipulated variables to be used by a process controller (,) for controlling the sewage treatment plant (,). The values of the manipulated variables calculated by the manipulated variable calculating unit (,) and the process data read from the process data storage unit (,) are given to a process condition estimating arithmetic unit (,). Data on estimated process conditions estimated by the process condition estimating arithmetic unit (,) is given to the manipulated variable calculating unit (,), and then the manipulated variable calculating unit (,) calculates values of the manipulated variables again.
