Design and operation of hot water syst ems and application for on site electrochemically generated ch lorinedioxide for control of legionella

Objective

Scientific objectives and approach:

The intend research work consists of 5 workpackages besides exploitation plans and project management.
The WP "Specifications" requires literature survey on guidelines and legislation of hot water quality and design and operation of hot water quality and design/operation of hot water systems to define demands for water disinfection processes
The WP "Design and operation" will provide new innovative design parameters and seek optimal operation systems for temperature control and corrosion protection.
The WP "Methods for prevent the growth of Legionella" will assess existent disinfection methods and possibilities for introduction of new methods and tests.
The WP "Innovative energy and effect optimised temperature schemes" will specify the optimal operation conditions in hot water systems.
The WP " development of chlorine dioxide systems" will provide system set-up for application at end-users.

Problems to be solved:

In recent years the outbreaks of Legionnaires Disease have been reported from most of the European Countries and Associated states (2.136 cases in 1999).The objective of this project is to reduce the rate of Legionella infections in Europe by development of new innovative methods and equipment, which can reduce the energy demand by combining temperature variations with other disinfection methods in hot water systems. Design and operation of hot water systems combined with innovative disinfection treatment processes such as electrochemically generated chlorine dioxide will eliminate the need for side storage of disinfectants. Th effects of the disinfection treatment on water quality and biofilm formation will be investigated by field studies at critical end-users such as hospitals, institutions, hotel and bigger apartment buildings.

Expected Impacts:

The expected result will be attained by achievement of the following
milestones: 1)Common specification of quality parameters for hot water 2)
Suitable test procedures for disinfection processes 3) System set-up for
temperature schemes and chlorine dioxide systems 4) Validation of the methods by end-user studies 5)Satisfactory project by thorough exploitation plans with cost estimates.
