Process and device for generating chlorine dioxide for the disinfection of water

摘要

A process and a device (1, 1') for generating chlorine dioxide for the disinfection of water are presented. The process comprises the steps of providing a cartridge (2) having a first inlet (7) and an outlet (8), the cartridge (2) in terms of flow being filled with sodium chlorate (9) between the first inlet (7) and the outlet (8), introducing a stream of an acid through the first inlet (7) into the cartridge (2), wherein the acid is reacting with the sodium chlorate (9) to at least chlorine dioxide and water, wherein the water and at least one part of the not reacted sodium chlorate (9) are forming an aqueous sodium chlorate solution and wherein the chlorine dioxide is forming a gaseous phase above the aqueous sodium chlorate solution, taking out through the outlet (8) a gaseous stream of the chlorine dioxide from the gaseous phase, and providing the gaseous stream of the chlorine dioxide to be introduced into the water to be disinfected.
