CONTINUOUS CURATIVE AND PREVENTIVE PROCESS FOR LEGIONELLOSIS DISINFECTION AND CONTROL IN STORAGE AND PRODUCTION EQUIPMENT AND DOMESTIC HOT WATER DISTRIBUTION CIRCUITS

摘要

A continuous process of disinfection and fight against legionellosis in storage and production equipment and domestic hot water distribution circuits includes: a section (B) of permanent thermal shock ensuring the curative and preventive anti-legionellosis function, using a water intake and preheating tank, a thermal shock tank at a temperature of up to 109 degreC and a heat exchange means; - optionally, permanent injection into the water introduced into section (B) of a flow rate of an electrolytic solution obtained by continuous electro-chlorination carried out in a section (A) of production of free chlorine by electrolysis (making it possible to ensure the presence of free chlorine in the hot water at a concentration of about 1 to 2 mg / l); the process possibly also comprising a section (C) of permanent electrolysis ensuring cathodic protection against corrosion of the tanks used in section (B), by impressed current, and the continuous generation of free chlorine within the tanks, to compensate for the disproportionation effect of free chlorine favored by high temperatures.
