| 简介 |
The present invention provides an electrolysis system and an electrolysis method for the same in which non-purified water containing a trace amount of alkali earth metal ions, such as calcium ion and magnesium ion is applied as raw material, having a configuration in which the raw material water is supplied to the cathode compartment (1), featuring that scale of the alkali earth metals including hydroxide can be prevented from depositing on the surface of the cathode (2) provided in the cathode compartment (1). The present invention prevents scales of hydroxide and others of the alkali earth metal from depositing on the cathode surface (2), by covering the substantially entire surface of the cathode (2) with the cation exchange resin-contained, alkali earth metal scale-preventive film in the electrolysis system having a configuration comprising a diaphragm (5), an anode compartment (3) separated by the diaphragm (5), a cathode compartment (1) separated by the diaphragm (5), an anode (4) provided in the anode compartment (3), a cathode (2) provided in the cathode compartment (1), and raw material water containing alkali earth metal ions supplied to the cathode compartment |
