Abstract
A water treatment control system using a fluorescence analyzer includes an activated carbon injection equipment having an activated carbon injector , a fluorescence analyzer provided on the upstream of the activated carbon injector , and a flowing water flowmeter An activated carbon injection rate necessary to reduce a trihalomethane formation potential is calculated by an activated carbon injection rate calculating apparatus based on a measured value from the fluorescence analyzer An activated carbon injection amount from the activated carbon injector is controlled by an activated carbon injection amount control apparatus based on the activated carbon injection rate and a measured value from the flowing water flowmeter
