Dosing & UV Treatment -Legionella Control

Humans are rarely infected by drinking water contaminated with Legionella. The main threa tof Legionella to human health is inhaling mists or droplets containing this pathogen. Shower heads can become a reservoir for these bacteria. Other favoured environments for Legionella include spray nozzles, spas, hot tubs, cooling towers, recirculating hot water systems below 65ºC and whirlpool baths. Legionella is also frequently associated with biofilms (thin surface films of microorganisms), scaling, and sediment in water systems. In such environments, bacteria can find necessary nutrients as well as protection from disinfectants. In Australia chloramine disinfection has replaced chlorination in most water supplies, and there is some evidence to suggest that chloramines are far less effective in legionella control.Legionella are resistant to conventional chlorination practices. The following disinfection methods have been used to control this microorganism in institutional water systems:HyperchlorinationChlorine dioxideCopper-silver ionsSuperheat and flushUltraviolet lightTankless flash heatersWe offer a rage of chemical dosing systems and also ultraviolet disinfection for treatment of institutional waters
