Continuous method of disinfection against legionellosis in warm water supply a directions

摘要

A continuous method of disinfection and combating legionellosis in the equipment of the storage and production and the circuits of the distribution of hot water comprises: a section (b) of thermal shock is permanent, providing the curative and preventive anti - legionellosis, using a reservoir of the admission of water and, a reservoir of thermal shock at a temperature ranging up to 109 degrec and a means of heat exchange; - optionally, the continuous injection into the water introduced into the section (b) of a flow of an electrolytic solution obtained by an electro - chlorination carried out in a continuous section (a) for the production of free chlorine by electrolysis (which makes it possible to ensure the presence of free chlorine in the hot water at a concentration of about 1 to 2 mg / l); the method may also comprise a cross section (c) for the electrolysis is permanently ensuring the cathodic protection against corrosion of the reservoirs used in the section (b), by an impressed current, and the generation of the free chlorine in the tanks, in order to compensate for the purpose of the dismutation of free chlorine promoted by the high temperatures.
