Over the years, disinfection of facilities has been performed in a variety of ways. The use of chlorine has been widespread in our society. Nevertheless, use of chlorine also has important drawbacks for the facilities. If appropriate anti-corrosive agents are not used, the chlorine attacks the facility leading to corrosion of the circuits, shortening their life considerably.

DOYA BIOLOGICA has developed over the years disinfection protocols that have been adapted to current legislation for preventing Legionela in facilities that are considered risk. Cooling towers, evaporative condensors, hot sanitised water, potable water, humidification trays, evaporative humidifiers should be subjected to a strict control of monitoring that includes shock disinfection to render the facilities safe. For these purpose, DOYA BIOLOGICA uses appropriate anticorrosive agents, biodispersants and anti-foaming agents to protect the facilities.

Numerous protocols have been developed to carry out the disinfection. Thus, after successive outbreaks of Legionella in different autonomous regions, different legislation has come into force in the Regions that have passed laws to deal with this problem (Madrid, Cataluña, Valencia, Galicia and Extremadura). All these, as well as guideline UNE 100-030-94 for preventing Legionelosis in facilities, have formed the basis for the publication of the  865/2003 dated 4 July, issued by the Ministry of Health, which standardises these guidelines.
