Ultraviolet Sterilizing Water Purification
Ultra-violet (UV) light kills disease-causing micro-organisms such as Ecoli with a 99.9% effectiveness. UV sterilization adds nothing to, and removes nothing from the water and is extremely cost effective by volume. UV Water Sterilization technology seeks to use the same process as nature to provide drinking water that is completely safe.
By exposing contaminated water to high intensity UV light, disease causing micro-organisms are rendered harmless and the water produced is safe, clean and fresh.
In nature, the sun produces UV rays which have a germicidal effect on disease causing pathogens in water. When these contaminants are exposed to UV light, they are rendered harmless and the output water is considered disinfected. Additional water filters are available for any system to filter out sediments, odors, bad tastes water sterilization units will provide an adequate UV dose to kill the following
How UV Water Purifiers work
Ultraviolet (UV) light is invisible and is emitted by different light sources, including the sun. At certain intensities, UV light emits enough radiation to kill the DNA in bacteria and other microorganisms. An ultraviolet water purification system typically consists of a UV light source with an output of around 254 nanometers which produces radiation of a significantly greater intensity than the radiation produced by sunlight.
The UV light source is mounted in front of a flow chamber through which water passes. The water is exposed to the UV light source as it passes through the chamber. Any harmful microbes and bacteria that are present in the water are rendered sterile by the exposure to the germicidal radiation.
UV radiation is so effective that it can eliminate up to 99.99% of bacteria and viruses, including those associated with water-borne illnesses such as Typhoid, Gastroenteritis, Hepatitis, Flu and Cholera. UV water purification can be used to treat water whether it's from a municipal water supply, a drinking-water well, lake or a spring.
Limitations in UV Water Filters
As remarkable as the technology is, ultraviolet water purification by itself is not enough to render water completely safe for drinking purposes. That's because UV radiation works only on microorganisms such as bacteria and viruses. UV light is of little use in eliminating other contaminants in water such as chlorine, heavy metals and VOC's (Volatile Organic Compounds).
VOCs are toxic, man-made chemicals that leach into ground water during the manufacture of products such as paints, petroleum products and refrigerants.

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.
Principle of Operation
UV water disinfection system design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection chamber. The dosage, as it applies to UV disinfection, is a function of time and the intensity of UV radiation to which the water is exposed. Exposure time is related to the flow rate, the higher the flow rate, the lower the exposure time or the lower the flow rate, the higher the exposure time. The UV intensity is the amount of energy, per unit time, emitted by germicidal lamp. The Dosage is the product of UV intensity and the exposure time.
Limitation of Use
The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.
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)

Disinfection system is a pressure vessel made of low carbon stainless steel,with a higher reflectivity of ultraviolet ray,the ultraviolet sterilizing lamp is installed in the cylinder body through the quartz tube,tube surface does not contact the water directly.
which reduce the influence of water temperature on tube surface temperature.in order to improve the disinfection effect,the quartz tube is easy to assemble and disassemble,O ring is for sealing at two ends with nut locked.
The manual cleaning mechanism could clean the quartz tube.there are power switch,guide light for running and lamp failure,the ballast and other electronic are inside the control panel.
