Abstract:
1. A device for producing acidic electrolyzed water with no salt in the generated water, the device comprising: an apparatus comprising an anode in an anode compartment, a cathode in a cathode compartment, an anion-permeable membrane separating the anode and the cathode compartment a protection membrane provided with slit-shaped discontinuities, the protection membrane functioning to protect the anion permeable membrane by allowing venting of gas, wherein the anode and cathode and membrane are formed in an integrated, unitary electrode assembly that is readily exchangeable, wherein water for electrolysis is circulated through the anode compartment one or more times and wherein the rate of flow of water for electrolysis through the anode compartment is regulated; a chloride-containing electrolyte in the cathode compartment; a direct current power source wherein a direct current voltage is applied between the anode and the cathode; a raw water tank wherein the water for electrolysis is provided from the raw water tank; a liquid distribution device; a liquid mixing device; a circulation pump wherein the water for electrolysis from the raw water tank is distributed by the circulation pump to the liquid distribution device wherein the water for electrolysis distributed into the liquid distribution device is further distributed both to the anode comportment to create electrolyzed water and to the liquid mixing device for non-electrolyzed water, wherein the non-electrolyzed water is used to immediately dilute the electrolyzed water; a recycle loop; wherein the liquid mixing device mixes the electrolyzed water and the non-electrolyzed water to create diluted electrolyzed water; wherein the diluted electrolyzed water in the liquid mixing device is recycled back into the raw water tank; wherein the diluted electrolyzed water is circulated in the recycle loop from the raw water tank to the anode compartment and back to the raw water tank one or more times to create the acidic electrolyzed water; wherein the flow rate of the water for electrolysis through the anode compartment is between about 5 to about 40 ml/min per ampere of current passing between the anode and the cathode; and wherein the chloride-containing electrolyte in the cathode compartment is replaced after a preset number of coulombs from the direct current voltage are passed through the membrane.
