UV water Sterilizers
What is an UV water sterilizer?
The UV water Sterilizer is a water filtration device that uses an ultraviolet light bulb to kill microscopic organisms that are free floating in the water. Parasites, viruses, algae and bacteria (good and bad) are the type of things that are "killed" after passing through the ultraviolet sterilizing unit. UV sterilizer devices can be used on swimming pools, in liquid factories (think beer) and in the home aquarium using an aquarium UV sterilizer. Some large water purification centers employ some sort of UV sterilization on the outgoing water. These sterilizer units are also sometimes used in outdoor ponds to help control algae growth and they seem to do a decent job.
When using a UV Sterilizer in a home aquarium, the UV unit should be placed last in the filtration line. You want to first filter the aquarium water through your mechanical filter and then run the water through the UV device before returning the water to your fish tank. By first removing the solids in the aquarium water with your mechanical filter (canister filter, etc), you are helping your UV unit to attain maximum operational efficiency.<o:p>
What does a UV sterilizer do?
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 inch) or rocks (e.g., algae).
How does it work?
UV sanitation systems eliminate chlorine-resistant microorganisms, which are common causes of pool closures. These systems reproduce UV radiation inside light chambers via powerful lamps, which emit germicidal UV-C light that is used to disinfect pool and spa water. Facilities equipped with these systems consume fewer chemicals and allow sterilizers to be more effective. How much more effective depends on the water's hardness, pH and other water chemistry factors. UV-C causes permanent damage to a number of microorganisms almost instantly as the water circulates through the light chamber. By disrupting the microorganism's DNA, protozoans, viruses and bacteria are unable to replicate and remain inert. This light, however, works only on water that flows through the chamber. Water in dead zones isn't treated by the light and the light does not act as a residual, thus the need for the presence of a halogen. The effects of UV-C are immediate and do not alter the water's composition.
Low versus medium pressure lamps
There are two types of UV lamps - a low-pressure, high-output lamp, which emits monochromatic UV rays at 254 nm, and a medium-pressure lamp, which emits UV rays between 200 and 600 nm. Generally, low pressure lamps are better suited for residential applications because of their lower initial cost and electricity use, while medium pressure lamps are typically designed for large commercial installations because of their greater sanitation abilities. The distinction can be chalked up to cost, flow requirements and the ability to destroy chloramines. Due to its large light spectral, medium pressure lamps are more effective at reducing chloramines and improving air quality.

UV specification
Product application
Ultraviolet light treatment is a widely recognized and proven method of disinfection of water and has several advantage over other disinfection methods such as chlorination, ozonation, etc,UV light does not add anything to the water ,such as ,undesirable color ,odor , taste , or flavor ,nor does it generate harmful byproducts. It adds only energy in the UV radiation. Also, UV disinfection requires only a fraction of the contact times required by other disinfection methods. It is fast, efficient, effective, economical and environmentally-friendly.
Water Quality (in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.
UV wavelength (nm)
DOSAGE is the product of intensity & time
dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter
(μW-s/cm2)
Note:1000μW-s/cm2=1mj/cm2(milli-joule/cm2)
