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-Pure™ 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 Europe and USA.

A new study reviewing the initial 16 hospitals outfitted with copper-silver ionization systems revealed the method’s ultimate control over the occurrence of legionella*.
Occurrences of hospital-acquired legionnaire’s disease prior to the 1995 study are documented for each of these facilities. Since that time, reports reveal a complete lack of hospital-acquired legionnaire’s disease in these same facilities once the copper-silver disinfection method was instituted.

Disinfecting hospital water systems using the copper-silver ionization method of disinfection will eliminate the existence and thwart the onset of legionnaire’s disease.

Pressurised Hot Water  in a Hospital

Hot Water installation in a large Hospital

• A safe water supply.
• Elimination of Thermostatic Mixer Valves.
• Low temperature hot water storage means reduction in energy costs.
• Low installation costs to hot or cold water systems.
• Low running costs equivalent to a 100w bulb for a 30 bed home.
• Simple to operate and maintain.
• New technology low scale electrode cells (important in hard water areas).
• Non Corrosive to pipework.
• No taste or smell.

Disinfecting hospital water systems using the copper-silver ionization method of disinfection will eliminate the existence and thwart the onset of legionnaire’s disease.
A new study reviewing the initial 16 hospitals outfitted with copper-silver ionization systems revealed the method’s ultimate control over the occurrence of legionella*.
Occurrences of hospital-acquired legionnaire’s disease prior to the 1995 study are documented for each of these facilities. Since that time, reports reveal a complete lack of hospital-acquired legionnaire’s disease in these same facilities once the copper-silver disinfection method was instituted.

It is noteworthy that, prior to the employment of the copper-silver ionization method, the majority of the 16 acute care hospitals participating in the study (75%) had tried to disinfect their water by various other techniques, including superheat and flush, ultraviolet light and hyperchlorination. The study was just one phase of a larger assessment undertaken to guide health care institutions in their selection of the most efficient and effective long-term mode of water disinfection.

Installing Tarn-Pure™ on your hot and/or cold water system will save time and money and most importantly will reduce the risk of Legionnaires Disease or other water-borne bacteria infecting the users of your buildings.
