Abstract
A method is provided, which includes generating a cleaning liquid by a combination of a sparging process and an electrochemical process that produces an anolyte and a catholye.
Claims21
A method comprising:
- a) sparging a liquid with an electrolysis cell that lacks an ion exchange membrane;
- b) electrochemically activating the sparged liquid to produce a sparged anolyte electrochemically activated (EA) liquid and a sparged catholyte EA liquid with a functional generator comprising an anode chamber and a cathode chamber, which are separated by an ion exchange membrane, wherein the sparged liquid feeds the anode chamber and the cathode chamber;
- and
- c) performing the sparging step a) and the electrochemical activating step b) along a flow path through the electrolysis cell and the functional generator that lacks a liquid feedback path from an output of either the electrolysis cell or the functional generator.

A method comprising:
- a) electrochemically activating a liquid to produce an anolyte electrochemically activated (EA) liquid and a catholyte EA liquid with a functional generator comprising an anode chamber and a cathode chamber, which are separated by an ion exchange membrane;
- b) sparging at least one of the anolyte EA liquid, the catholyte EA liquid or both of the anolyte EA liquid and the catholyte EA liquid with an electrolysis cell that lacks an ion exchange membrane;
- and
- c) performing the electrochemically activating step a) and the sparging step b) without feeding any of the anolyte EA liquid, catholyte EA liquid or the liquid sparged by the electrolysis cell back to an input f the functional generator.

A method comprising:
- a) sparging a liquid with an electrolysis cell that lacks an ion exchange membrane to produce a sparged liquid;
- b) feeding the sparged liquid into an anode chamber and a cathode chamber of a functional generator, the anode and cathode chambers being separated by an ion exchange membrane;
- c) electrochemically activating the sparged liquid to produce a sparged anolyte liquid and a sparged catholyte liquid with the functional generator;
- d) onboard an apparatus, combining all of the sparged anolyte liquid with all of the sparged catholyte liquid to produce a combined sparged anolyte and catholyte liquid;
- and
- e) dispensing substantially all of the combined sparged anolyte and catholyte liquid as a working liquid from the apparatus to a surface to be cleaned upon electrochemical activation in step c).
