Ultraviolet (UV) Disinfection System is an extremely effective way to combat microbial contamination in water. However, microbes have to be exposed to UV-C light in the proper amount in order to effectively disinfect the water. UV Disinfection Systems are used in many different applications ranging from the purification of drinking water in individual homes to disinfecting water supply of entire townships to industrial waste water treatment. UV treatment for water is recognized as a safer and more cost-effective way to disinfect water for industrial applications Industrial Water Treatment.
UV sanitization is useful in almost any application where microbial free, safe and pure water is required and where there is a chance of the water being contaminated before it reaches the final point of use.
UV light of wavelength 253.7 nanometers is used for disinfection of bacteria, viruses, molds, algae and other microorganisms which multiply and grow. UV disinfection technology destroys the DNA of microorganisms which leaves them dead and unable to grow further. UV disinfection technology can be used for drinking water disinfection, process water disinfection, waste water disinfection, and surface disinfection. Other than disinfection applications, this technology can also be used for TOC removal and Ozone destruction. Plus, there is the UV sterilizer for hospitals, factories and offices.
In the UV water disinfection technology, the UV light disinfects by penetrating microorganisms and destroying their DNA. DNA plays an important role in organisms’ functions and reproduction hence destroying the DNA prevents the organism from being active and multiplying. This UV energy (wavelength of 240 – 280 nm) is also naturally found in sunlight in very small quantities. The same energy is produced in stronger intensities with the help of high mercury discharge lamps, commonly known as UV lamps.
No bacteria, viruses, molds or their spores can survive when exposed to the correct dose of UV light. Therefore UV is considered as the best solution for water sterilization and for room sterilization, there is the UV mobile sterilizer machine that can be used.
HOW DOES ULTRAVIOLET DISINFECTION WORK ?
The UV treatment process is an extremely quick physical process. UV light mutates and / or degrades DNA. DNA (or deoxyribonucleic acid) is the part of the cell that gives an organism its instructions on how to function and reproduce.
When the DNA is damaged, the organism becomes unable to function because its ‘instructions’ are garbled or missing. An organism that has no instructions cannot function and reproduce and cannot cause infection. It is rendered harmless and eventually dies.
Water is disinfected as it runs through a stainless steel chamber that contains a UV-producing lamp. In the UV disinfection process, water is purified as it runs through a stainless steel chamber (also called a ‘reactor’) that contains a special UV-producing lamp. As the water flows past the lamp, the microbes in the water receive a lethal dose of UV.
The water is then safe to be drunk. However, different organisms require different levels of UV energy to disrupt their DNA. This energy level is known as a UV dose.
