Bacteria Killing UV Water Sterilizer Water Disinfection System
Optimal service condition:
As UV is a short- wavelength light wave, it has low radiant energy
and weak penetrating power and can
only kill the microorganisms it directly radiates on. Therefore, in
order to enhance the bacteria-killing
efficiency and ensure the security of drinking water, the incoming
water into the sterilizer must meet
the following standard, (and if exceeding the following standard,
the killing efficiency may be affected).
Total iron content
Less than 0.3ppm(0.3mg/L)
Less than 0.05ppm(0.05mg/L)
Total suspended matter
Less than 10 mg/L
Less than 0.05 mg/L
Less than 120 mg/L
Less than 15centigrade

Spectrum UV Systems provide a sleek, compact design and economical ultraviolet water
treatment for low flow and medium flow applications such as: light
commercial reverse osmosis systems, water vending machines, food
industry, laboratory, medical facility water, pharmaceutical,
cosmetics processes, final electronic component rinsing and
recirculation loops to name a few.
Spectrum UV Systems produce little change in water temperature even
after prolonged periods of no water flow, making them ideal for
many application requirements.
*No need to handle toxic or corrosive chemicals or by-products.
*Microbiologically free water without the use of potentially
*UV imparts no change in taste, odor, pH or conductivity.
*No trihalomethanes (THM’s) formation.
*Fast and simple installation with three connections (two water and
*Maintenance involves annual lamp replacement (provided water
quality parameters are met) with no need to turn off water flow.
*Automatic, unattended and user friendly operation.
*Compact units with 304 or 316 (upon request) stainless steel
reactor chamber, polished for laboratory and medical use, require
*Micro-organisms are inactivated within seconds; eliminates the
need for long retention times or retention tanks.
*Very low power consumption; less than 40 Watt bulb to effectively
treat from 1 to 100 gallons per minute.
*High output low pressure mercury vapor lamps with high isolation
*Little change in water temperature even after prolonged periods of
no water flow.
*Open end high quality quartz sleeve and stainless steel gland
What is UV sterilization?
A UV sterilizer is used to control infections by stopping the
spread of microorganisms from one
fish/coral/invertebrate to another through the water. It is also
used in pond applications to control
free-floating algae. When operated correctly, free-floating microorganisms will be killed by the UV light. Note
that the organisms must be in the water that flows to
the UV sterilizer. The UV light has no residual effect and will not
kill organisms attached to fish (e.g., adult stage
of ich) or rocks (e.g., algae).

In which types of systems should UV sterilizers be used and what
are the benefits?
A UV sterilizer may be used in any aquarium, however, in smaller
aquariums (less than 24 gallons), the cost
of the unit may make it impractical. UV sterilizers are most
helpful in multiple tank systems that share a common
filter. In a single tank system, they are beneficial in controlling
the spread of an infectious disease if one occurs.
This is especially true in heavily stocked tanks and those with
large amounts of live rock and corals that could
make catching and isolating a diseased fish difficult, or the use
of certain medications contraindicated. Disease
control is especially important when adding new fish to an
established aquarium, since 98% of the hobbyists do
not use a quarantine aquarium.
In ponds, UV sterilizers are one of the best ways to control
free-floating algae, allowing the pond owner to see
and enjoy the fish. The UV sterilizer will also kill free-floating
bacteria in the pond water.
The UV sterilizer utilizes a germicidal fluorescent lamp that
produces light at a wavelength of approximately 254
nanometers (2537 Angstroms). The water with the bacteria/algae
passes over the bulb (or around the bulb if a
quartz sleeve is used) and is irradiated with this wavelength. As
the light penetrates the bacteria/algae, it
mutates the DNA (genetic material), preventing
growth/multiplication of the organism.
Q. Are UV sterilizers a good replacement for biological and
A. NO. UV sterilizers are not a replacement for good biological and
mechanical filtration, regular water changes,
or proper c
ontrol of the nitrogen cycle.
Q.What is the proper maintenance schedule for UV sterilizers?
A.The quartz sleeve will need to be checked monthly and removed and
cleaned with rubbing alcohol.
larger UV sterilizers have wiper mechanism units installed for
