Benefits of technology
[0026]Another objective of the invention is to improve cleanliness, as the cleaning solutions produced by the electrolytic cell are effective for cleaning all surfaces by removing fine particles or the like wherefrom and sanitizing solutions produced by the electrolytic cell are effective for sanitizing all hard surfaces by oxidation of micro-organism and viruses.
Problems solved by technology
When the two-chamber cell depicted in FIG. 1 is used, the cathode water is not necessarily suitable for actual cleaning or a surface treatment without rinsing the surface with distilled, RO or tap water.
The anode water is not necessarily suitable for sanitizing hard surfaces without rinsing the surface afterwards with distilled, RO or tap water.

Embodiment Construction
[0043]The present invention is directed to the construction of an optimized cylindrical electrolysis cell that produces a cleaning solution and simultaneously a sanitizing solution. The diluted Sodium Hydroxide solution is more alkaline, contains no salt residues and, therefore, the solutions can be used to clean any surface without rinsing the surface afterwards with distilled, RO water or tap water. The diluted Hypochlorous Acid solution contains no salt residues and its free available chlorine content as well as pH can be adjusted. As a result, surfaces can be effectively sanitized using a sanitizing solution which pH and free available chlorine is ‘tailored’ to sanitize a certain surface taking into account chlorine consumption and in line with various sanitizing procedures as set by regulatory agencies such as the FDA, EPA, USDA and CDC. Certain surfaces require a more acidic sanitizer whereas other surfaces are damaged by the acid nature of the sanitizer. In these cases, a mor...

Abstract
An Electrolysis cell assembly to produce diluted Sodium Hydroxide solutions (NAOH) and diluted Hypochlorous Acid (HOCL) solutions having cleaning and sanitizing properties. The electrolysis cell consists of two insulating end pieces for a cylindrical electrolysis cell comprising at least two cylindrical electrodes with two cylindrical diaphragms arranged co-axially between them. The method of producing different volumes and concentrations of diluted NAOH solutions and diluted HOCL solutions comprises recirculating an aqueous sodium chloride or potassium chloride solution into the middle chamber of the cylindrical electrolytic cell and feeding softened filtered water into the cathode chamber and into the anode chamber of the cylindrical electrolysis cell.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a cylindrical electrolysis cell assembly for producing simultaneously a diluted Sodium Hydroxide and diluted Hypochlorous Acid solution for usage as cleaning and sanitizing solutions by electrolysis of an aqueous saline solution. The method comprising a cathode chamber, an electrolyte chamber and an anode chamber separated by two cylindrical diaphragms to prevent presence of salt residues in the cleaning and sanitizing solutions and whereas pH and free available chlorine content of the sanitizing solution can be altered.BACKGROUND OF THE INVENTION[0002]Electrolysis cells are used for the production of cleaning and sanitizing solutions from brine. Also, electrolysis cells are used to produce a sanitizing solution to disinfect water or other media. Many types of electrolysis cells exist for these purposes. The basic feature of these cells is two concentrically disposed cylindrical electrodes with a diaphragm separating the s...
