What is Germicidal Ultraviolet?
UV-C light is germicidal - i.e., it deactivates the DNA of bacteria,
viruses and other pathogens and thus destroys their ability to multiply and
cause disease. Specifically, UV-C light causes damage to the nucleic acid of
microorganisms by forming covalent bonds between certain adjacent bases in the
DNA. The formation of such bonds prevents the DNA from being unzipped for
replication, and the organism is unable to reproduce. In fact, when the organism
tries to replicate, it dies.What are the beneficial uses of germicidal UV?
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. Ultraviolet purifiers utilize
germicidal lamps that are designed and calculated to produce a certain dosage of
ultraviolet (usually at least 16,000 microwatt seconds per square centimetre but
many units actually have a much higher dosage.) The principle of design is based
on a product of time and intensity - you must have a certain amount of both for
a successful design.
How do ultraviolet purifiers work?
purifier units contain one or more germicidal ultraviolet lamps. The germicidal
lamp is a short wave low pressure mercury vapor tube that produces ultraviolet
wavelengths that are lethal to micro-organisms. Approximately 95% of the
ultraviolet energy emitted is at the mercury resonance line of 254 nanometers.
This wavelength is in the region of maximum germicidal effectiveness and is
highly lethal to virus, bacteria and mold spores. Therefore, the water or air
that passes through the chamber is exposed to the germicidal uv light and the
genetic material of the micro-organism is deactivated, which prevents them from
reproducing and renders them harmless.

UV Industrial Applications
UV irradiation has emerged as a proven treatment
technology for the treatment of process water and wastewater in industrial
applications. UV treatment has been established as a low cost,
environmentally-friendly treatment technology that provides exceptional
disinfection benefits. Exposure to UV irradiation ensures the inactivation of
all types of microorganisms, including bacteria, viruses, yeasts, moulds and
spores. UV treatment can also be combined with other oxidants (i.e. ozone,
hydrogen peroxide) to create hydroxyl radicals for removal of many other harmful
contaminants.
UV treatment has numerous advantages in industrial applications. UV treatment
can easily inactivate, even with low UV doses, chlorine resistant compounds such
as Giardia and Cryptosporidium. UV is a "green technology", as it is chemical
free and produces no disinfection by-products (DBPs). The systems can also be
easily retrofitted into existing treatment plants due to its small footprint.
Eco-Logical Technology offers a wide range of low pressure and medium pressure
UV systems for various industrial applications:
Food and Beverage
UV disinfection equipment can be used prior to filters and/or membranes or after
carbon beds to disinfect the source water and minimize microbial contamination
at beverage plants, reducing backwashing and servicing frequencies. Waste water
streams can also be treated with UV in order to disinfect and reduce BOD levels
for safe discharge or reuse.
Power and Cogeneration
UV disinfection equipment can be used prior to RO/UF membranes or mixed bed
resins to disinfect and lower TOC levels, reducing backwashing and servicing
frequencies, limiting the need for chemical biocides, and minimizing downstream
contamination problems.
Oil Field Water Injection
UV equipment placed after particle filtration, which minimizes reservoir
plugging, disinfects the water to prevent microbial contamination from being
injected into the oil reservoir. The use of UV disinfection virtually eliminates
the need for water treatment chemicals and expensive dosage monitoring
equipment, preventing the chemical composition of the oil from being altered. \
Pharmaceutical & Cosmetics
UV disinfection equipment can be used prior to filters and/or membranes or
after carbon beds to disinfect the process water and reduce TOC levels, thereby
reducing backwashing and servicing frequencies for downstream treatments. UV
equipment can also be implemented in the recirculation line from purified water
storage tanks, for residual ozone destruction and to provide additional
disinfection and microbial control. Waste water streams can also be treated with
UV in order to disinfect for safe discharge. UV can be combined with other
advanced treatment technologies (i.e. hydrogen peroxide, ozone, etc.) to remove
numerous harmful and difficult to remove compounds.
Chemical Process
UV disinfection equipment can be used prior to filters and/or membranes or
after carbon beds to disinfect the process water, reduce TOC levels, minimize
microbial contamination, thereby reducing backwashing and servicing frequencies.
Waste water streams can also be treated with UV in order to disinfect for safe

Aquaculture
UV disinfection equipment can be positioned after particle filters to
disinfect the source water and significantly reduce microbial contamination
prior to fish and shellfish exposure. The treatment leads to reduced BOD levels,
and reduced disease and mortality of aquatic species
Electronics
UV disinfection equipment can be used prior to RO/UF membranes or mixed bed
resins to disinfect and lower TOC levels, reducing backwashing and servicing
frequencies, limiting the need for chemical biocides, and minimizing downstream

Accordingly, UV irradiation is regarded by many industry professionals as the
most technically effective and cost-effective treatment option for numerous
industrial applications.
In order to simplify the integration of UV into existing or future processes,
Eco-Tec has engineered and fabricated a broad range of UV systems to fit nearly
every application.
