An apparatus is provided, which includes a mobile body configured to travel over a surface, a source of a liquid, a liquid dispenser and a flow path from the liquid source to the liquid dispenser. A functional generator is coupled in the flow path, which comprises an anode chamber and a cathode chamber separated by an ion exchange membrane and which electrochemically activates the liquid from the liquid source which is passed through the functional generator.

Cleaning apparatus having a functional generator for producing electrochemically activated cleaning liquid

A method and apparatus (100, 300, 370, 380, 400, 500, 600) are provided for receiving a cleaning liquid (14, 106, 502, 602) having a pH in a range between pH6-pH8 and an oxidation reduction potential (ORP) between ±50mV. The liquid (14, 106, 502, 602) is converted into an anolyte liquid and a catholyte liquid (20, 22, 44, 45, 51, 52, 190, 192) having respective pHs outside of the range between pH6-pH8 and having respective ORPs outside the range between ±50mV. The anolyte and catholyte liquids (20, 22, 44, 45, 51, 52, 190, 192) are applied to a surface (125, 302), wherein the anolyte and catholyte liquids (20, 22, 44, 45, 51, 52, 190, 192) are, for example, in a combined state on the surface (125, 302) and substantially neutralize to a pH between pH6-pH8 and an ORP between ±50mV within one minute of the time at which the anolyte and catholyte liquids (20, 22, 44, 45, 51, 52, 190, 192) are converted.

The present invention relates to a process to limit the content of impurities in the production of alkali metal chlorate, by integrating the production of chlorate with the production of chlorine and alkali metal hydroxide, which auxiliary chemicals are used in the chlorate process. The alkali metal chlorate is produced by electrolysis of a purified electrolyte containing alkali metal chloride, alkalization of the chlorate electrolyte obtained and precipitation of the chlorate formed by evaporation of the chlorate electrolyte. The very pure water separated in the crystallizer and alkali metal chloride is used in a membrane or diaphragm cell in the production of alkali metal hydroxide, which hydroxide is used in the production of alkali metal chlorate. Either pure chlorine or hydrogen chloride absorbed in water can be used in acidification, at which hydrogen chloride is produced from chlorine and hydrogen generated in the process.

A process for the production of sodium chlorate comprising electrolyzing an aqueous sodium chloride solution in a diaphragmless sodium chlorate cell, characterized in that an aqueous sodium chloride solution containing, as impurities, calcium, magnesium, barium and the like is contacted with a chelating ion exchange resin to remove the impurities and the resulting saline solution is supplied into a diaphragmless sodium chlorate cell, thereby enabling sodium chlorate to be produced at a stable electrolytic voltage. Further, there is provided a process for the production of sodium chlorate using a combination of a sodium chlorate cell and a cation exchange membrane process type chlorine-alkali cell, characterized in that a weak saline solution taken out of an anode chamber of a cation exchange membrane process type chlorine-alkali cell is supplied with sodium chloride to form an aqueous sodium chloride solution, which is subsequently contacted with a chelating ion exchange resin to remove calcium, magnesium, barium and the like contained as impurities in said solution, and at least part of the resulting purified saline solution is supplied into a sodium chlorate cell, whereby sodium chlorate formed as a by-product in the chlorine-alkali cell can be effectively recovered and the elevation of the electrolytic voltage of the sodium chlorate cell with the lapse of time can be well prevented.
