UV Sterilizers
How does an Ultraviolet water sterilizer work?<o:p>
The ultraviolet ray is a kind of invisible light wave to the naked eye. It exists on the outside of the purple ray on the spectra thus it is called the ultraviolet ray. The ultraviolet ray is subdivided in wave band A (UVA), wave band B (UVB), wave band C (UVC). The wave length of UVC is between 100nm to 280nm - and the most effective germicidal wave band is 253.7nm.<o:p>
1. Principles: If you expose the water to UVC spectrum at the wave peak of 254nm for a period of time the nucleic acid, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of microorganisms will absorb UV rays and be damaged by the rays - thus they perish - so the water is sterilized. UV rays have a certain effect on protein and other life forms too.
2. Sterilization range: UV water sterilizer can effectively kill the algae, fungi, bacteria, rickettsia and virus to purify the water.
3. Merits of the sterilizer: UV sterilizer is a completely physical way to sterilize water. It is easy to use, cost effcetive , broad spectrum, does not require any chemicals, generates no secondary pollution, does not create corrosion, leaves no residue and is easy to maintain.
4. Application range: UV water sterilizer can be mounted as a pre or rear sterilization equipment with domestic or industry water purification equipment. It can be applied to various kinds of water purification.
5. For it to work effectively the water must be free of aprticles larger than 5 micron.<o:p>
Application
1.Food processing industry, including juices, milk, drinks, beer, practical oil and canned food.
2.Electronic industry.
3.Hospitals, various laboratory and high levels of pathogenic body water disinfection.
4.Households building, residential, office buildings, hotels, restaurants, water factories.
5.Purification and disinfection of shellfish, fish cleaning and disinfection
6.Military camp, field water supply system
7.Urban wastewater disinfection.
8.Swimming pool, other recreational water disinfection
9.Thermal power, nuclear power plant industrial, central air conditioning system cooling water.
10.Biological, chemical and pharmaceutical, cosmetics for the production of cooling water.
11.Sea water, fresh water breeding, aquaculture water
12.Agricultural water disinfection
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.
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)
