Cholera and water filtration - UV A + B
Would UV light (A as well as B of either or) kill the cholera bacteria? Thanks
EnviroHealth expert
Yes, it would, but it needs to be the right amount of UV light delivered to the right amount of water in a very specific way i.e. you can't just put a glass of water in the sun and hope for the best! There is a water purification device called a "Steripen" that uses ultraviolet rays to purify water - but you have to use it following the manufacturer's instructions to the letter.
The UV light destroys the DNA of pathogens - both A and B do so in different ways.
