Ultraviolet radiation has the most bactericidal efficacy in 240nm-280nm wave band, especially in 253.7nm.Its bactericidal principle is: Because the cell absorb wave light farthest in 250nm-270nm, in fact absorbed ultraviolet radiation has effect on DNA, which gets up a actinism. The energy of ultraviolet radiation is absorbed by alkali group in DNA to change and destroy microbial framework (DNA-ribotide), then lead to ribotide framework broken and the end of the organism or losing the fuction of copy. Once the fuction is broken, sterilization or antisepsis is achieved.
Now ultraviolet radiation has been widely used in drinking water.pure water.electron.medical treatment.atmosphere cleanse antisepsis and sewage disposal in protecting environment and so on, it is one of the optimal manners of decontaminating water accepted in the world.
Characteristic:
1. Widely application.fast seed.high efficiency and good impact
2. Easy to use, small volume, portability, saving-power and high life.

UV-C wave band: 200nm-275nm
