UV radiation changes microorganisms' DNA, inhibiting reproduction, hence disinfecting the water
The design of UV systems depends on required UV dose, flow rate, and media parameters
Germicidal effect occurs through photon absorption by DNA and RNA
Photochemical reaction causes DNA and RNA dimerization, halting microorganism replication (inactivation)
UV - Efficiency depends on exposure duration, lamp strength & water quality
UV Wavelengths
UV radiation is electromagnetic radiation between x-rays and visible light.
UV wavelengths range from 100 to 400 nanometers.
The UV wavelengths are divided in 4 groups, each with a different germicidal effect:

The ability to change lamps without removing the module or undoing any underwater seals, is one of the biggest benefits of the ver- tical installation. Operators have to simply open the module, unplug the lamps, pull them out, install the new lamps and close lid.
