Bacteria are unicellular microorganism that cause harm and diseases in the human body.
Water is an essential component in everyday life to humans. However if not careful water can become infected creating water born diseases such as cholera. After many years of research scientists have come up with a way of sterilizing water with the use of UV rays (Ultraviolet Radiation) emitted from an LED. Ultraviolet radiation is found between X-ray and Visible light on the Electromagnetic spectrum, it has a wavelength of around 100 to 400 nm which is used to kill bacteria and sterilize drinking water. The process of which this is known as: Ultraviolet Germicidal Irradiation. There are 3 types of Ultraviolet Radiation: UV-A (100-280nm), UV-B (280nm - 315 nm), and UV-C (315 nm - 400 nm).
Ultraviolet Germicidal Irradiation
Germicidal UV radiation is produced and sent by a mercury vapour lamp. As these types of Ultraviolet radiation can be harmful to humans this method of Germicidal Irradiation is practiced behind enclose spaces with shielding in order for us to be protected.
During Ultraviolet Germicidal Irradiation UV-C is used which ultimately disrupt and deactivate the DNA found in bacteria and viruses. This will result in that Bacteria not being able to carry out its function and reproducing by binary fission. In bacteria Nucleic Acids are also disrupted as of the formation of covalent bonds and further breaking bonds in the DNA and Nucleic Acids. If the bacteria and viruses are unable to reproduce this will result in them not passing on the DNA and nucleic acids and increasing in numbers. Once the DNA absorbs these photons this will create a DNA pyrimidine dimers (producing same molecules) this will alter the order of the bases and eventually it will lead to a random mutation where microorganisms will eventually die.
Scientists have ensured us that water will now be free of bacteria and any water born disease thanks to this LED gadget.
