Ultraviolet light irradiation of potable water for Legionella colonization in a hospital water distribution system.

Author(s) : LIU Z., STOUT J. E., TEDESCO L., BOLDIN M. M., HWANG C. C., YU V. L.

Summary

Ultraviolet (UV) irradiation of potable water to prevent Legionella colonization has been suggested as a promising disinfection method. The authors performed a controlled evaluation of the effect of UV irradiation of hot and cold water supplies in a hospital colonized with Legionella by inserting the UV units near the point of use. Experience and results are described. UV plus prefiltration can prevent Legionella recolonization after disinfection if the UV units are installed near the point of use. Experience and results are described. The advantages of UV include easy installation, low expense, and no adverse effects on water or plumbing.
