Effectiveness of UV
Disinfection
The outer skin of bacteria and viruses differ in
thickness. The thickness of this skin determines the
amount of UV light exposure required to prevent their
reproduction (rendering them dead).
The intensity of the light is measured in Micro
Watt seconds per centimetres squared (m Wsec/cm²).
The most common undesirable bacteria and viruses require
an average exposure of between 4,000 and 12,000 m
Wsec/cm2.
UV is suitable for a wide range of applications both
in the home and commercial premises where there is
a risk of or water is suspected of containing harmful
bacteria or viruses.
