Copper-silver ionisation to control water-borne diseases

Throughout history, copper and silver have been known to purify water.

Copper-Silver Ionisation is the most environmentally responsible approach to water disinfection. It saves the needless energy consumption of constant hot water (thermal) and excessive use of hazardous chemicals such as chlorine.

Since 1981, Tarn-Pure has pioneered copper-silver ionisation in the UK and overseas, initially focussing on swimming pools, wherein ionisation lessens the quantity of chemicals required, with benefits to human skin, eyes and hair.

Water-borne diseases, including Legionella in swimming pools

In 1985, a major Legionella outbreak at Stafford District General Hospital led to 22 deaths. Soon after this tragedy, it became clear that copper-silver ionisation could make a major contribution to the control and elimination of legionella.

In October 2007, a seminal US research study by Dr Janet Stout was published by the American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE). 

Consequently, Tarn-Pure has led the development of copper-silver ionisation as a biocide for the control and elimination of legionella and other water-borne bacteria. 

Tarn-Pure equipment has been chosen by research scientists all over the world as the standard for long-term and other studies into the benefits of copper-silver ionisation.

In food processing, Tarn-Pure units have been installed in vegetable and salad washing lines, replacing chemical biocides, such as chlorine and citric acid. 

Tarn-Pure is more effective than chemicals and fully approved for organic produce by the Soil Association, extending shelf life for many leaf products.

As a supplement to normal cleanliness and disinfection procedures Tarn-Pure treated water eliminates listeria, e-coli and salmonella in kitchens and food preparation areas.

Tarn Pure systems are fully compliant with the UK Health & Safety Directive ACOP L8: "Legionnaires' disease - The control of Legionella bacteria in water systems".
