Legionella Treatment for Health Care
Hospitals and Care Homes represent a Legionella risk to a group of patients or residents vulnerable through age, who are immuno-compromised, suffering post operative vulnerability or existing respiratory disorder when exposed to water droplets from showers, baths, toilets etc. Of course, apparently healthy visitors and members of staff can be equally at risk from infection.
Historically cold water has been considered safe from the risk of Legionella if stored and distributed at below 20°C (68°F). Of course this is not always possible with roof top or attic tanks in the summer or with cold water pipes sharing ducts with hot water or steam distribution pipes. Hot water was always considered to be at greater risk of contamination particularly at temperatures in the range 40°C to 50°C (104°F to 122°F) and previous recommendations for treatment centred on raising the water temperature to 60°C (140°F) at the point of heating. This then increased the risk of scalding and brought about the installation of thermostatic mixer valves (with their attendant problems) to reduce the temperature again to 43°C (110°F). The Tarn-PureTM Silver/Copper ionization system of water treatment eliminates all of the above. The process is approved under the Health & Safety Executive Approved Code of Practice and Guidance "The Control of Legionella Bacteria in Water Systems" document L8 for the United Kingdom, is recognised in the "European Guidelines for Control and Prevention of Travel Associated Legionnaires' Disease", and is proven and accepted in many other countries including the USA. The system injects low levels of silver and copper ions into the water system (within EU and WHO limits for drinking water) to provide a residual disinfection that spreads through the whole system being treated. Among its many benefits the system offers:
