    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.

Compared with other disinfection forms, UV sterilizer has the following advantages:

Ø  High efficient sterilization: normally kill 99%-99.9% bacteria within 1 to 2 seconds.

Ø  Broad spectrum: UV rays has the broadest spectrum, killing almost all bacteria and virus.

Ø  No secondary pollution: don’t add any chemical agent, it does not create secondary pollution to water and surrounding environment, do not change any ingredients in water.

Ø  Safe and reliable to operate: traditional disinfection technology such as adopt chloride and ozone, the disinfectants themselves are highly toxic and flammable material. While UV sterilizer has no such potential safety hazard.

Ø  Low maintenance fee: UV sterilizer occupies a small area (and have a simple structure requirement, so smaller total investment and lower operation cost are easy to achieve).Its cost only half than chlorine disinfection in kiloton water treatment.
