Abstract
An object of the invention is to reliably prevent the precipitation of scale during a reclamation step in a deionization treatment. A water reclamation system and a deionization treatment device of the present invention each comprises a deionization section, a supply section which supplies a scale inhibitor to a water to be treated, and a control section. The control section acquires a supply start time and a supply stop time for at least one of the scale inhibitor and a low ion concentration water based on the concentration of a scale component in the deionization section, and causes the supply section to supply at least one of the scale inhibitor and the low ion concentration water in the interval between the supply start time and the supply stop time.
