PROCESS FOR PRODUCING A DISINFECTANT BY ELECTROCHEMICAL ACTIVATION (ECA) OF WATER, DISINFECTANT PRODUCED IN SUCH A MANNER AND USE THEREOF

摘要

A process is proposed for producing a disinfectant by electrochemical activation (ECA) of water, by adding to the water to be disinfected an electrolyte solution, in particular a sodium chloride or potassium chloride solution, and subjecting the electrolyte-solution-charged water in the form of a dilute water/electrolyte solution to an electric current in an electrolysis reactor having a cathode space having a cathode and also an anode space spatially separated from the cathode space and having an anode, by applying direct current to the electrodes, in order to put the water/electrolyte solution into a metastable state suitable for disinfection. In order to ensure reliable disinfectant action of the electrochemically activated water, with high reproducibility, the invention provides that the pH of the dilute water/electrolyte solution in the anode space of the reactor is controlled to a value between 2.5 and 3.5, in particular to a value in the region of 3, in such a manner that the potential of the anodic oxidation is controlled (potential-controlled anodic oxidation, PAO). The invention further relates to a disinfectant produced in such a manner and also to use thereof.
