How UV Light Kills Bacteria in Water

This video shows how bacteria in water are effectively inactivated by UV light.
Ultraviolet (UV) disinfection is an extremely effective way of inactivating and killing bacteria in water, as no known bacteria or virus is resilient to UV light. This includes pathogens such as Cryptosporidium and Giardia, which water treatment alternatives such as chlorine is unable to treat.
Using UV light disinfection, the cell walls of bacteria, virus, and protozoa are penetrated, permanently altering the DNA of the microorganisms. This effectively inactivates the microorganisms, making them unable to infect and reproduce. As the cells are not able to reproduce, they will not be able to cause any infection, thus killing the bacteria and viruses. This causes the pathogens to become non-infectious by damaging its DNA.
UV disinfection has become the preferred water disinfection solution to inactivate and kill microorganisms, bacteria, and viruses due to its many advantages. A water disinfection alternative is chlorine, which has proven to lead to several health complications such as respiratory diseases. The many advantages of UV include:
✅ A lower carbon footprint compared to the alternative disinfection methods
✅ Low maintenance, administration, and operating costs
✅ No dangerous chemicals involved (no residuals, handling and storage)
✅ No by-products being added in the process
✅ No change of the water properties such as pH and temperature
✅ Instant treatment, meaning there is no processing time
✅ Safe and simple implementation
ULTRAAQUA is an international manufacturer of advanced UV water disinfection systems for a wide range of water treatment applications.

Underrated

How is this video and channel so unknown?!?

I thought it excited electrons in their cells which can react to oxygen and that's what kills them. Oxygen reactive species - Google the term.

Mostly for disinfection UV-C light is used .. it's the highest energy uv light... It can directly damage the dna base bonding it, look up the term "photodimerization " in google... Rather than just ionising an electron out, It damages the dna itself.

Rip to all the microorganisms that died for this video #viruslivesmatter

Better insert the 5G with microchip for coronavirus
