  • Publication number: 20220387480
    Abstract: A system and a method are provided for making hypochlorous acid using saltwater with sodium bicarbonate. The system includes an electrolytic cell, a quantity of saltwater solution, and a quantity of sodium bicarbonate. The quantity of saltwater solution is poured into the electrolytic cell and then undergoes an electrolytic process. As a result of the quantity of saltwater solution going through the electrolytic process, a hypochlorous acid solution is yielded. In order to ensure a pure hypochlorous acid solution is formed, the quantity of sodium bicarbonate can be added into the electrolytic cell along with the quantity of saltwater solution before the electrolytic process or the quantity of sodium bicarbonate can be added into the hypochlorous acid solution after the hypochlorous acid solution is yielded. This process adjusts the pH level of the hypochlorous acid solution, and thus, produces a purer hypochlorous acid solution.

  • Publication number: 20210394130
    Abstract: A system and a method make a saltwater solution for electrolysis through the process of flowing water through a salt chamber to dissolve salt crystals and outputting the resulting saltwater solution into a saltwater container. The system includes a salt chamber, a remaining quantity of salt crystals, a filter, and a saltwater container. The salt chamber is a chamber that contains the remaining quantity of salt crystals. The salt chamber and the saltwater container are in fluid communication with each other, and thus, the saltwater container can receive the resulting saltwater solution. The salt chamber includes a chamber inlet and a chamber outlet. The filter is connected across the chamber outlet in order to retain undissolved salt crystals within the salt chamber.
