Process for generating chlorine dioxide and apparatus therefor
 Described is an apparatus for the generation of chlorine dioxide, comprising: a cylindrical, insulated body tube; a hollow inner opposite electrode column with a cross section of polygon, which is a triplicate structure where a sieve type electric tube is sandwiched between two electric columns made of a mixture of porous ceramic and powdery metal; a cylindrical outer opposite electrode inscribed in the body tube, having a triplicate structure made of the same materials as the inner opposite electrode column; an ozone-detecting sensor; a chlorine dioxide-detecting sensor; and a sensor switch for electric pressure difference, the hollow inner opposite electrode column being concentric with and present inside the outer electrode and both producing unequalized electron density upon application of electric field. Chlorine dioxide is generated in the apparatus by flowing pure water through the sieve type electric tube, to produce ozone therein and then flowing hypochlorite the same sieve type electric tube, to react with the ozone produced.
