Apparatus and method for producing electrolyzed water

A method for producing electrolyzed water, the method comprising:

• (a) injecting an amount of a cleaning solution to mix with a water solution;
• (b) flowing the mixture of the cleaning solution and the water solution into an input portion of an electrochemical cell;
• (c) sensing a cell current in the electrochemical cell;
• and
• (d) adjusting the amount of the cleaning solution flowed into the electrochemical cell responsive to comparing the cell current with a preselected current.
• (e) sensing an output pH of an amount of solution exiting an output portion of the electrochemical cell;
• and
• (f) flowing an amount of a catholyte solution exiting the output portion of the electrochemical cell to mix with the cleaning solution entering the electrochemical cell responsive to comparing the output pH with a preselected pH.

An apparatus for producing electrolyzed water, the apparatus comprising:

• an electrochemical cell having an input portion and an output portion, the electrochemical cell having first and second chambers separated by a membrane defining an anode chamber and a cathode chamber;
• a solution reservoir containing a solution and having an outlet and having an outlet in fluid communication with the electrochemical cell;
• a first pump having an input end in fluid communication with the outlet of the solution reservoir and an output end in fluid communication with the chambers of the electrochemical cell, wherein the first pump flows an amount of the solution from the solution reservoir to enter the electrochemical cell;
• a current feedback sensor to sense a cell current in the electrochemical cell;
• and
• a current control unit in data communication with the current feedback sensor and the first pump, wherein the current control unit includes a feedback component that compares the cell current with a preselected current and adjusts the amount of solution flowed from the first pump responsive to the comparison between the cell current with the preselected current.
