for potable water needs that is easy to
install and use with minimal supervision, maintenance, and space. Also,
UV LED modules can be installed in
areas where current UV lamps cannot
be used, such as cold storage facilities,
transport, and small disinfection apparatuses.
Upsizing from Bench-Scale to
Industrial Disinfection Applications
Within the next decade or so, UV
LEDs will quite likely fill many of the
roles that LPM lamps currently fill
in terms of UV-mediated safety solutions for liquids and surfaces. Modular
devices use UV-A LEDs for industrial
curing purposes. Replacing these chips
with UV-C LEDs emitting a germicidal
wavelength offers such devices potential
for use in the disinfection of food products moving along a conveyor as well as
the conveyor itself.
There is also the potential to inte-
grate germicidal UV LEDs into indus-
trial water and beverage disinfection.
Currently, UV light is one of the most
popular disinfection methods for mu-
nicipal drinking water and wastewater.
Replacing LPM lamps in these disinfec-
tion apparatuses with energy-efficient
UV LEDs could result in significant
energy savings for these municipali-
ties while eliminating the risk of lamp
breakage leading to mercury contamina-
(usually fresh or minimally processed
produce) is submerged in water under
constant agitation, and the entire rinse
is exposed to UV light. UV LEDs could
also be used in place of LPM lamps
in certain devices that use UV light to
disinfect produce submerged in water,
agitated by air jets (Figure 5).
