Legionella Prevention in Cooling Towers
Reducing Legionella risk requires water treatment, biocide application, regular cleaning and maintenance records to be carried out together.
When cooling towers are not operated correctly, biofilm formation, sediment build-up and stagnant water zones can increase microbiological risks. Legionella management is therefore not a one-off cleaning but a discipline of regular monitoring and documented maintenance.
Preventive maintenance approach
Regular blowdown, filtration, water treatment, biocide dosing and mechanical cleaning must be applied together. Drift eliminators, fill, the basin and the water distribution system should be inspected periodically.
Monitoring and records
When temperature, conductivity, pH, biocide level and microbiological analysis results are recorded, risky trends are noticed early. The Ensotek service approach arranges the maintenance plan according to the facility's operating regime.
