Feed water comprising an aqueous salt solution is supplied to an anode chamber and to a cathode chamber. The feed water is cathodically electrolyzed in the cathode chamber to produce alkaline electrolyzed water (catholyte) and is anodically electrolyzed in the anode chamber to produce electrolyzed water (anolyte) whose pH is modified. A portion of alkaline catholyte from the cathode chamber is recycled back to the feed water during continuous electrolysis to provide a blend of feed water and alkaline catholyte to the anode chamber to control pH of the anodically electrolyzed water therein to provide more stable bactericidal activity thereof over time.

Method and apparatus for electrolyzing water

A firmness measuring device for non-destructive testing of objects with rough surfaces (such as fruit) is disclosed. The device comprises the following components: a means to generate an impulsive jet of a fluid (such as air) aimed at the surface of the object under test; a laser to generate a beam of coherent light aimed at the area on the surface of the object under test impacted by the fluid jet; a detector to sense the light reflected off of the surface of the object from the laser beam; an analyzer to determine the amount of deformation of the surface caused by the fluid jet based on the input to the detector; and a controller to coordinate the release of the impulsive jet with the analyzer.
