UV disinfection for drinking water is an acceptable alternative disinfectant under the drinking water regulations worldwide, as long as the equipment has proof of performance (third party validation). NSF is a certified testing facility that conducts UV validations under the NSF 55 Class A protocol.
Sterilight SPV systems have undergone validation with NSF and hold certification to deliver an accepted dose of 40mJ/cm2.
What is UV
Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. The water treatment industry uses a high-powered form of UV light called UV-C or “germicidal UV” to disinfect water.
How Does UV Light Work
UV-C rays penetrate microorganisms and destroy their ability to reproduce, effectively
rendering them harmless. It’s a simple but effective process, destroying a minimum of 99.99% of harmful microorganisms, including E. coli, Cryptosporidium, and Giardia. Not only is it safe and highly effective, UV does not change the taste, color, or odor of water. It simply removes the risk of illness caused by microbial contamination, making water safe.
Who Uses UV Disinfection Systems
For more than 30 years, institutions, consumers and businesses have relied on VIQUA’s
environmentally friendly UV technology to disinfect their water supplies. Top candidates
for UV disinfection systems include:
- Rural homes and cottages
- Nursing homes
- Resorts and holiday camps
- Community water systems
Syngineering typically install UV Sterilisation systems after MBR, MBBR, UF and Reverse Osmosis systems to ensure that the permeate produced is of the highest quality.
