Effective Legionella Surveillance in Cooling Towers


rqmicro.COUNT enables cooling tower operators to monitor the presence of Legionella with reliable results generated on-site or in labs within 2 hours.

Cooling towers use evaporation to remove heat energy from water and thereby release aerosols into the atmosphere. If Legionella is present, the aerosolized water can spread the bacteria over miles and endanger surrounding residents. Regular disinfection and cooling tower maintenance protects facility operators, visitors, and residents from exposure to Legionella . The required frequency of measures depends on the cooling load, use of biocides, the environmental conditions present in the area where the cooling tower is located and the cooling tower’s design.

Cleaning, disinfecting, and remediating cooling towers involves a hierarchy of protocols that form a water hygiene management program. rqmicro.COUNT proposes a solution to determine and control the effectiveness of water hygiene management based on direct insight provided by single-cell counting of viable bacteria.
