No Measurable Residue UV-C 254nm UV Water Sterilizer

Ultraviolet Water Purifiers
Ultraviolet (UV) water purification systems are thought to offer the most cost-effective way of protecting residential drinking water against biological contaminants. UV purification systems can be used to protect against water-borne viruses, bacteria, molds and pathogenic disease-causing microorganisms such as giardia and cryptosporidium. Even viruses such as the hepatitis virus, which are known to be highly resistant to chlorine-treated water, can be relatively easily eliminated through UV treatment.
 


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.

 One of the biggest advantages of using a UV water purifier is that it is very cost effective at killing a majority of the harmful microbes associated with most common water-borne illnesses. On average, home UV water purifiers start at just $250 for a relatively small point of use system and top out at around $1400 for a whole house system. The systems consume only as much energy as a 60-watt bulb. Importantly, UV water filters do not introduce chemicals in the water. As a result, the taste and color of the water remain virtually unaltered and there is also no danger of any harmful bi-products resulting from the use of UV filters. In addition, UV water purifiers are easy to install, are easy to maintain and do not damage septic tanks or plumbing.<o:p>
 
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.

                 DOSAGE is the product of intensity & time
dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter

 Technical parameters sheet  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.
