UV Sterilisation

Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance. UV-C disinfection has the benefit of being both efficient and one the most energy effective methods of sterilisation.

UV-C light is germicidal and operates most efficiently at a wavelength of 250 – 260 nanometers. It has a photolytic effect whereby the radiation destroys or inactivates the microorganism so that it can no longer multiply. Unlike other techniques, UV-C photolysis rarely produces potentially dangerous by-products.

Micro-Organisms affected by UVC

A broad range of microbial species are rendered inactive by UVC radiation:

Fecal Coliforms Salmonella enteritidis
Bacillus anthracis Salmonella paratyphi
Bacillus subtilis, spores Salmonella typhi
Bacillus subtilis Salmonella typhimurium
Campylobacter jejuni Shigella dysenteriae
Clostridium tetani Shigella flexneri (paradysenteriae)
Corynebacterium diphtheriae Vibrio cholerae (V.comma)
Escherichia coli Yersinia enterocolitica
Klebsiella terrigena
Legionella pneumophila
Sarcina lutea
Mycobacterium tuberculosis
Pseudomonas aeruginosa
Shigella sonnei
Staphylococcus aureus
Streptococcus faecalis
Streptococcus pyogenes
MS-2 Coliphage
F-specific bacteriophage
Hepatitis A
Influenza virus
Polio virus
Giardia lamblia
Cryptosporidium parvum
