WATER-QUALITY MANAGEMENT DEVICE, WATER-QUALITY MANAGEMENT SYSTEM, AND WATER-QUALITY MANAGEMENT METHOD

摘要

Provided are: a water-quality management device capable of analyzing multiple types of water-quality parameters for a circulating water system such as one for coolant or boiler water while in the field, and quickly presenting a suitable measure on the basis of the analysis results; a water-quality management system; and a water-quality management method. This water-quality management device is equipped with: an input unit (112) for receiving the input of a plurality of water-quality parameters obtained by measuring a water sample collected from a water treatment facility; a storage unit (118) for storing data about a measure which incorporates changes to the plurality of water-quality parameters and the water treatment state of the water treatment facility; a computation unit (116) for referring to the data about the measure and selecting the water treatment state corresponding to the inputted plurality of water-quality parameters; and a display unit (114) for displaying the water treatment state selected by the computation unit (116).
