Does UV light kill bacteria in water?

Does UV light affect bacterial growth?
Ultraviolet (UV) light prevent the growth of bacteria by damaging their DNA. It's also effect protein secondary structure when ormatic amino acids absorb uv light. Ultraviolet light inactivates bacteria by forming pyrimidine dimers in DNA, which can interfere with transcription and replication.

Why do you have to clean a UV bulb?
If the bulb or sleeve gets covered by a film or mineral deposition, the UV light coming out of it will be partially or fully blocked. Therefore, you will have to clean the bulb or the sleeve regularly. Finally, the distance of the lamp from the water also plays a role.
What happens when water passes over algae?
Every time water (with algae/ bacteria) passes over the bulb, it is irradiated with this wavelength. As the UV light penetrates the algae or bacteria, it causes mutation in the DNA (disrupts the genetic material inside the bacterial or algae cells). As a result, it stops their growth or multiplication in the water.
