A pilot-scale reactor for continuously generating sodium hypochlorite (NaClO), which is applied to the cleaning-in-place (CIP) and the sterilizing-in-place (SIP), is introduced in this paper. The electrolytic cell of the reactor is constructed as a tubular electrochemical reactor with a nylon net membrane between the electrodes and with a layer of rare-earth metallic oxide, RuO2, as the active catalytic coating on the titanium anode surface. The performance of this generator is then analyzed from the point of view of reaction engineering.Experimental results indicate that the electric current efficiency of the reactor is above 82%. Biological study shows that the sterilizing water with the available chlorine content can effectively kill most microorganisms on the walls of food equipment.
