UV disinfection equipment

Outline

UV disinfection equipment

Ultra-violet rays can effectively inactivate chloride-resistant pathogenic protozoa such as Cryptosporidium, Giardia and so forth.
By combined use with chloride disinfection, the safety of water can be improved at a lower cost.

Mechanism of UV disinfection

Structure of typical bacteria cell

Ultra-violet rays have a wavelength from 380 nm to 100 nm. Particularly, rays with a wavelength of 253.7 nm effectively stop fungal propagation, because they are easily absorbed into the DNA necessary for bacteria and viruses to survive and communicate genetic information.

Our low voltage UV lamp has an output peak at 253.7 nm so that effective disinfection can be achieved.

Characteristics
