Electromagnetic emission within the range of 200-350 nm with a peak within 260± nm is characterized by the higher bactericidal effect. Action of ultraviolet emission causes changes in the structure of microorganism cell walls leading to their death.

UV-sterilant represents a metal body with bactericidal lamp inside it. It, I nits turn, is placed in a protective quartz tube. Water contacts with quartz tube and becomes treated with ultraviolet and, accordingly is disinfected.

Advantages
Uv rays destroy vegetative and spore-forming bacteria
Physical and chemical composition of treated water remains unchanged
No limit restriction on upper radiation dose limit
No secondary products
