System and method for generating and dispensing sodium hydroxide solutions

摘要

A system and method for generating and dispensing a diluted sodium hydroxide solution, the system including an electrolysis unit configured to electrochemically generate a concentrated sodium hydroxide solution from an anolyte solution formed with a non-chlorinated electrolyte. The system also including a dosing pump configured to receive dilution water and the concentrated sodium hydroxide solution at a high dilution ratio to produce the diluted sodium hydroxide solution, and a dispenser configured to dispense the diluted sodium hydroxide solution.

1. A system for generating and dispensing a diluted sodium hydroxide solution, the system comprising:
a deionizing unit configured to deionized water; a first water line configured to receive the deionized water from the deionizing unit; a second water line configured to receive dilution water; an electrolyte line configured to receive a non-chlorinated electrolyte; an electrolysis unit having an anode chamber and a cathode chamber separated by a barrier, wherein the anode chamber is configured to operably receive the deionized water from the first water line and the non-chlorinated electrolyte from the electrolyte line to form an anolyte solution in the anode chamber, and wherein the electrolysis unit is configured to electrochemically generate a concentrated sodium hydroxide solution in the cathode chamber from the anolyte solution in the anode chamber; a dosing pump configured to receive the dilution water from the second water line and a portion of the concentrated sodium hydroxide solution at a dilution ratio of at least about 100-to-1 by volume to produce the diluted sodium hydroxide solution; and a dispenser configured to dispense the diluted sodium hydroxide solution.
