Benefits of technology

The electrochemically activated solution effectively cleans and sanitizes surfaces without leaving residues, reducing the environmental impact and maintaining effective cleaning power by using meta-stable ions and free radicals, while also allowing for efficient oil extraction and neutralization of soiled water.

Problems solved by technology

While these detergents increase cleaning effectiveness for a variety of different soil types, such as dirt and oils, these detergents also have a tendency to leave unwanted residue on the cleaned surface.
Such residue can adversely affect the appearance of the surface and the tendency of the surface to re-soil and, depending on the detergent, can potentially cause adverse health or environment effects.
Similar disadvantages apply to cleaning systems for other types of surfaces and items.

Embodiment Construction

[0035]In one exemplary embodiment of the disclosure, a method and apparatus are provided, which use sparged liquid, an electrochemically activated (EA) anolyte and / or catholyte liquid, or a liquid that is both sparged and an electrochemically activated anolyte and / or catholyte liquid as the sole or primary cleaning liquid to substantially or completely eliminate the use of conventional surfactants / detergents during cleaning or disinfecting.

1. Surfactants Used in Traditional Cleaning Liquids

[0036]Conventional cleaning liquids generally include water and a chemical surfactant. As used herein, the term “surfactants” or “surface-active agents” refer to amphiphilic compounds that facilitate adsorption at surfaces or interfaces as well as aggregation at certain concentrations and temperatures. The chemical make up of a surfactant adheres to a particular molecular structure. The molecule is made up of at least two components, one that is water-soluble (hydrophilic), and the other water ins...

Abstract

A hand-held spray device is provided, which includes a tank for holding a supply of liquid to be treated and a functional generator, which is in fluid communication with the tank. The functional generator includes an anode chamber having an anode, a cathode chamber having a cathode and being separated from the anode chamber by an ion exchange membrane, wherein at least one of the anode or cathode comprises a metallic mesh, an inlet coupled to receive liquid supplied from the tank, which is coupled to the anode chamber and the cathode chamber. The functional generator is configured to combine an entire flow of anolyte liquid from the anode chamber with an entire flow of catholyte liquid from the cathode chamber along a single path that passes through an outlet. A pump pumps the liquid from the tank and out the spray output.
