UV Sterilizers disinfects water by ultraviolet radiation at a wavelength of 254nm. In particular, UV-C deactivates and/or destroys the DNA of viruses and bacteria, rendering them ineffective and not harmful to human health, which is the case with other methods of chemical disinfection (e.g. chlorine, ozone, etc.). Not all organisms respond in the same way if placed under ultraviolet radiation, some become inactive with relatively low doses while others need higher rates to obtain the desired inactivation. The proper use of UV Sterilizers helps to eliminate over 99% of the microbial load in the water, a whole range is available with many dose rate for any application.
