UV disinfection is an efficient, low cost and environmentally friendly process. UV light kills pathogenic
micro-organisms quickly without leaving any residues or harmful by-products.
The SLT Ultraviolet Sterilisers use UV lamps which emit UVC radiation at 254nm which disrupts the DNA in the microorganisms,
so they are either killed or their ability to replicate is destroyed.
The kill rate depends on the UV dose received by the micro-organisms, i.e. the time that a microorganism
is exposed to a certain intensity of UV radiation (Wm2). A UV dose of 400 J/m2, is recognized
internationally as a suitable dose to ensure safe disinfection of drinking water.
The disinfection performance of a UV system is determined by the intensity of the UV light, water flow
rate, the optical transmission of the water at 254nm and the geometry of the reactor. The sizing of the
UV system should be based on these parameters.
