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 steriliwave 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 :UV does not alter taste, outdour, colour or pH of the waterUV does not require the addition of chemicalsUV does not impart toxic by-products into the waterUV systems are compact and easy to installUV systems require very little maintenanceRunning costs are often lower than those of a household lightbulb.
Application:Food processing industry, including juices, milk, drinks, beer, practical oil and canned food.Electronic industry. Hospitals, various laboratory and high levels of pathogenic body water disinfection.Households building, residential, office buildings, hotels, restaurants, water factories.Purification and disinfection of shellfish, fish cleaning and disinfectionMilitary camp, field water supply systemUrban wastewater disinfection. Swimming pool, other recreational water disinfection Thermal power, nuclear power plant industrial, central air conditioning system cooling water. Biological, chemical and pharmaceutical, cosmetics for the production of cooling water. Sea water, fresh water breeding, aquaculture waterAgricultural water disinfectionModel 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)Note: 1. Auto cleaning function can be choosed.
2. Inlet/outlet direction and size can be choosed.
3. Material SS304 ,SS316L can be choosed.
