Description of the Related Art When electrolyzing water through a partition wall, for example, a semi-permeable non-charged membrane or an ion-selective charged membrane, among the electrolytes, anions are from the cathode chamber side to the anode chamber side, and cations are Each is transported from the anode chamber side to the cathode chamber side. Conventionally, from the viewpoints of user convenience and production efficiency of producers, design efforts have been made to reduce the electrode area provided in the electrolyzer and to maximize the flow rate of the source water flowing along the partition wall. Therefore, no attention was paid to the ionic species passing through the partition. Therefore, the permeation amount of oxygen molecules per unit weight of the generated water dissolved in the source water was very small, and was almost the same as the dissolved oxygen concentration in the source water.

供するものである。However, when the basic electrolysis-produced water was drunk, the pharmacological effect in vivo was not significantly exhibited. To improve the efficiency of the basic electrolyzed water generator, the flow rate of the source water was made extremely large, and the electrode area was made small for the purpose of downsizing the device, so the amount of permeated ion species in the generated water was extremely small. As a result, it was not possible to lower the dissolved oxygen concentration of the produced water obtained. The present invention has been made to solve such a problem, and an object thereof is to determine the flow rate of source water,
Alternatively, the invention provides a method for decreasing the dissolved oxygen concentration, which reduces the amount of ionized dissolved oxygen by increasing the electrode area.

The smaller the amount, the smaller the absolute applied current and the less the substance permeates from the anode to the cathode. Further, it is utilized by increasing the flow rate of the source water and increasing the electrolytic reaction area to increase the permeation amount of the substance and increase the content rate of the permeate contained in the produced water of both electrodes.

Further, assuming that the electrode area is Se, the absolute current I 1 is: I 1 = ISe (2) Source water flow rate J r is J r = V / tm 3 / hr (3) Anode-side permeated substance concentration ρ in generated water a is represented by ρ a = ωt 1 I 1 / J r = ωJ 1 Se / J r (4). However, ω is a parameter based on the properties of the film. Thus, permeate concentration [rho e on the cathode side is, ρ e = J r -ωJ 1 S e / J r (5) , and the reduction transport number of dissolved oxygen, respectively by the nature of the partition wall but has a unique value, If this is kept constant, the electrode area is increased and the flux of the source water is reduced, whereby electrolytically generated water with a low dissolved oxygen concentration can be obtained.
