The design of a UV disinfection
In the UV reactor design form, the commonly encountered doses have been preset. For more accuracy, it is recommended to have a transmittance measurement performed. Indeed, TSS, iron and turbidity can alter the passage of UVC.
In order to ensure the quality of the water and to keep it free of bacteria and other micro-organisms, it is common to use UV technologies.
The water passes through tubes where it receives UV radiation. Moreover, this radiation has a destructive wavelength for DNA.
On the other hand, the UV dose is the important parameter, because this dose ensures a correct inactivation of the bacteria.
Therefore, it is common to measure the UV transmission at 10 cm. This value represents the remaining dose at 10 cm depending on the water clarity.
The clearer the water, the closer the transmittance is to 100% and the more impotent the diffusion of the inactivating charge is.
