Klaran UVC LED Water Disinfection

Water Treatment

With a growing need for more effective, mercury-free ways to disinfect water, UVC LEDs are leading the way as a proven method for achieving affordable, microbiologically safe sources of water.

Expanding and increasingly dense urban populations place tremendous strains on infrastructure and industry—with water demands expected to increase 40 percent by 2030.

Kinds of Water Disinfection Methods

Water disinfection is the process of reducing the amount of harmful pathogens in a water supply. This can be achieved through simple chemical, filtration and radiation methods or a combination of techniques.

Chemical disinfectants and treatments are often reserved for municipal and large water distribution networks, while point-of-use (POU) and point-of-entry (POE) systems rely on filtration and deep ultraviolet light (UVC). In these systems, filtration removes chemical and organic contaminants, while UVC addresses microbial threats from bacteria, viruses and cysts.

Some systems will also combine UVC with photo-catalysts to produce hydroxyl radicals to help remove organic compounds and pharmaceuticals and personal care products (PPCPs).

Why UVC Disinfection

Once contaminated water has entered municipal distribution systems the health implications, cost and complexity of sanitizing these systems is significant. UVC LEDs can be integrated into on-demand POU water purification systems to protect families and homes from common pathogenic sources of waterborne illnesses.

UVC LEDs are used in these systems to protect against microbial contaminants- including bacteria (E. Coli, Pseudomonas, Legionella), viruses (Rotavirus, Adenovirus, Hepatitis), and parasites (giardia beaver fever, cryptosporidium).

Benefits of UVC LEDs

UVC disinfection remains the sole proven, practical and cost effective solution for addressing true microbial safety without impacting water's odor or taste. Although germicidal mercury lamps have been the trusted UVC source in the past, UVC LEDs are poised to replace them with innovative compact product designs.

  • More cost effective than germicidal lamps
  • More compact that germicidal lamps
  • Mercury free non-toxic UVC sources
UVC LEDs are better than mercury bulbs

Germicidal mercury lamps are commonly found in purification systems in homes and offices. While momentum is building around the Minamata Convention on Mercury, this toxic material is still used by business sectors which claim the absence of a viable technical and economic alternative. Mercury is now being abandoned in these applications due to the performance, price and availability demonstrated by Klaran UVC LEDs.
