Ultraviolet (UV) sterilizer

UV-Ultraviolet disinfection principle:

Invisible ultraviolet light is classified into three categories: UV-A，UV-B and UV-C . The wavelength range of A-band is in the 315-400nm , B-band is 280-315nm, C-band is 100-280nm . UV sterilization wave band is mainly between 200nm and 300nm, the band of 253.7nm is the strongest to sterilize. When all kinds of bacteria and virus in water or air go through the UV rays (253.7nm) Irradiation area, UV rays penetrate microbial cell membrane and nucleus, destroy the molecular link of DNA or RNA, which then kills all bacteria and virus in the water or air without using any chemicals or drugs. UV sterilization technology is the latest disinfection technology, which sprung up at the end of 1990s. UV185nm wavelength UV and air action can produce strong oxidation ozone , can effectively kill bacteria, and lead to high intensity outside, killing bacteria and viruses in a short period of time.

Feature:

1. UV does not alter taste, outdour, colour or pH of the water
2. UV does not require the addition of chemicals
3. UV does not impart toxic by-products into the water
4. UV systems are compact and easy to install
5. UV systems require very little maintenance
6. Running costs are often lower than those of a household lightbulb.

Application:

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

Model list:

UV wavelength (nm):

DOSAGE is the product of intensity & time dosage=intensity*time=microwatt/cm2*time=microwatt-seconds per square centimeter (μW-s/cm2)

Note:1000μW-s/cm2=1mj/cm2(milli-joule/cm2)
