Preventing Legionella in Cooling Systems – GCC Guidelines and the Role of Biocides
Keywords: legionella control GCC, biocide for legionella, cooling tower disinfection Dubai, legionella treatment UAE
Introduction
Legionella bacteria thrive in warm water environments, making cooling towers in the GCC especially vulnerable. Outbreaks can lead to severe public health incidents. Fortunately, biocidal water treatment is the most effective preventive measure.
Risks of Legionella in GCC
- Warm temperatures year-round
- High humidity in coastal cities
- Industrial facilities with inadequate tower maintenance
- Use of untreated groundwater or recycled water
Regulatory Focus in GCC
- UAE municipalities now require regular Legionella testing
- Oman’s health authorities recommend biocidal treatment and drift eliminators
- Hotels, hospitals, and malls face stricter audits post-pandemic
Biocidal Solutions
- Shock dosing with chlorine dioxide or bromine
- Weekly non-oxidizing biocide rotation to prevent resistance
- Use of bio-dispersants to penetrate biofilms
Conclusion
Legionella outbreaks can be avoided with proactive biocidal treatment of cooling towers, regular testing, and compliance with GCC safety standards. Protect your brand and your occupants by implementing a proven biocide program.
