FOR CONTINUOUS MONITORING OF
TAKE CONTROL OF YOUR NETWORK
WITH ATP 2G!
Water cooling towers that cool water via evaporation must be declared (or registered, depending on the power) as installations subject to regulations regarding environmental protection (ICPE - section no. 2921). Managing Legionella risks in cooling towers is also required for public spaces (ministerial statements from December 13, 2004 and December 14, 2013).
A methodical risk analysis (analyse méthodique des risques, AMR) is needed to limit the risk of Legionella distribution in the air and proliferation within a water-based network. The regulatory measures include primarily:
• a maintenance plan that defines the maintenance activities and preventive treatments to be applied;
• a surveillance plan to verify the effectiveness of preventive measures by tracking indicators (self-monitoring procedures and regulatory analyses) and to define the corrective measures to take if a shift in the indicator values is detected;
• a record of maintenance and monitoring activities.
Rapid microbiological analysis by ATP 2G cannot replace required biological analyses. However, it is a useful first line self-monitoring tool that is efficient, low cost, easy to implement and allows the facility manager to:
• use an efficient indicator to track the water quality of cooling networks in real time;
• enact a comprehensive risk analysis strategy based on measuring the total biological burden at risk points within the network;
• implement a self-monitoring procedure for evaluating the risk of the emergence of pathogenic germs. These measures can be easily implemented by the technical staff of the facility.
ATP 2G represents a significant advantage compared to culture-based methods (especially for the analysis of Legionella, as described in standard NF T90-431) because the results are obtained rapidly and on site. The user can quickly identify any biological shift within the installation, thereby increasing responsiveness in decision making and the efficiency of any corrective action taken. ATP 2G helps you take control of your network and optimize risk management.
• the formation of biofilms by heterotrophic bacteria (Pseudomonas sp., Aeromonas sp., Flavobacterium sp.) in tubes or the water run-off catch tray;
• a biological risk associated with the presence of Legionella pneumophila or biological conditions that favor the growth of this bacterium and the development of resistance to disinfection (biofilms, protozoa, algae).
• Measuring the total biomass of the water in cooling towers;
• Continuous monitoring of the microbiological quality of climate control networks in large public buildings (hospital centers, commercial centers);
• Optimize cleaning and disinfection of water networks, for example to minimize the dose of biocidal chemicals needed or to evaluate the efficacy of maintenance procedures.
• DSA™ for analyzing the interior surfaces of cooling towers (water run-off catchment chambers, exchangers, dehumidifiers, etc.) and analyzing samples (collection devices embedded in the network to enable evaluation of the level of biofilm contamination and the speed of their formation).
• Cooling towers in public establishments: climate control in hospital centers (university hospitals or local hospitals), rehabilitation centers, private clinics, residential care homes for seniors, group homes, commercial centers, private companies, etc.
• Industrial cooling towers: industrial cooling processes in the energy sector (thermal and nuclear power centers), the chemistry sector, the agro-food sector, etc.
