    "concept_summary": "Tap water containing dissolved sodium chloride is passed through an electrolysis reactor that separates the cathodic and anodic streams. The cathode produces an alkaline solution rich in sodium hydroxide; the anode produces acidic hypochlorous acid (or sodium hypochlorite when neutralised). Both solutions act as powerful oxidising agents for disinfection and cleaning.",

    "experimental_evidence": "Multiple peer-reviewed studies and industry trials (e.g., International Journal of Food Science & Technology 2005) demonstrate rapid reduction of microbial load on vegetables, food-processing equipment and clinical surfaces.
