Design and opreation of hot water systems and application for on site electrochemically generated chlorine dioxide for control of legionella

Objective

In resent years the outbreaks of Legionnaires' disease have been reported from most of the European countries (1442 cases in 1998). The objective of this project is to reduce the rate of infection in Europe by development of new innovative methods and equipment which can reduce the energy demand by combining temperature variations with other disinfections methods for controlling the growth of Legion Ella in hot water systems. Design and operation of hot water systems combined with innovative disinfections treatment processes such as electrochemically generated chlorine dioxide will eliminate the need for site storage of disinfectants. The effect of temperature schemes and disinfections treatments bio film will be investigated by field studies at critical end users such as hospitals, health institutions, hotels and bigger apartment buildings. The results will contribute to the existing knowledge and improve the practical use of disinfectants to prevent the growth of Legion Ella.
