UV Solutions for Prevention of Nosocomial Legionella

Aquafine UV Water Treatment technology is a proven solution for preventing nosocomial Legionella contamination of hospital water systems.

Legionnaires’ disease is a serious form of the bacteria Legionella, a pneumonia contracted by ingesting water that has been contaminated with the bacteria. Legionella bacteria are found naturally in the environment - usually water - and thrive in warm water, common for spas, cooling towers, hot water tanks, large plumbing systems, or parts of the large facility air conditioning systems.

Outbreaks of nosocomial Legionnaires disease might easily exist unnoticed in a hospital, resulting in patient illness or possible patient mortality. Hospital buildings have complex water systems increasing the risk for Legionella infection outbreaks.

Studies indicate implementing UV water treatment technology is a proven solution, as UV light inactivates the Legionnaire microbe by penetrating the cell wall and damaging the DNA, destroying its ability to reproduce.

UV Applications for Hospitals

  • Cooling Towers - Aquafine pioneered the technology utilizing UV light for chemical-free microbiological control for cooling tower applications.

  • Fountains - UV disinfection of decorative fountains is a complimentary way of providing an effective method of inactivating a wide range of waterborne pathogens including Cryptosporidium, Giardia and Legionella.

  • Laboratory/Research - A pharmaceutical water system could have several locations where UV equipment would be installed. Typical locations of installation would be post-carbon filter and pre-RO (reverse osmosis).

  • Medical Devices - UV technology is used in many medical device applications including microbial-free water before non-heat chemical sterilization. Aquafine partners with medical device manufactures, designing custom UV solutions to meet exacting product standards.

  • Potable Water - the most common application of UV light in water treatment in globally. Aquafine offers bioassay validated products, meeting strict regulatory drinking water requirements including USEPA, DVGW and NSF.
