摘要
The purpose of the present invention is to reliably prevent the precipitation of scales in a reclamation step in a desalination treatment. Each of a water reclamation system (1) and a desalination treatment device (4) according to the present invention is equipped with a desalination unit (10), a supply unit (20) which can supply a scale inhibitor to water to be treated, and a control unit (40). In the control unit (40), a supply start time and a supply stop time for the scale inhibitor and/or low-ion-concentration water is obtained on the basis of the concentration of a scale component in the desalination unit (10) to achieve the supply of the scale inhibitor and/or the low-ion-concentration water to the supply unit (20) at a time of point included between the supply start time and the supply stop time.
