TES electrolysis disinfecting systems of electrochemical reaction principle with researcher Korean scientific technique (KIST) the domestic research team develop with joint research and the water which passes the electrolysis electrode which with the patent technique (0425773) which wins an environmental department head tube acquires NT and EM marks with the product which disinfects the inside coliform which will bite with the complex sterilization effect in compliance with the electrolysis at the time of occurrence radical and an electric potential difference and the general germ, the establishment expense and maintenance utility charge to be few the maintenance being easy is strong point.
