How did Ultraviolet (UV) systems work in the commercial RO plant?
The UV system is an effective way to treat the microbes present in the water. The ultraviolet system contains ultraviolet light. Microbes are exposed to UV light, which helps in the alteration of the DNA of these microbes. As a result, the microbes lose their capability of replicating themselves.
The UV system is used for various purposes ranging from homes to industries. Often in RO plants, UV technology is installed because it effectively kills the microbes present in the water. It acts as a disinfectant used to kill the microorganisms like bacteria, viruses, cysts, etc. The UV lamps contain the wavelength of 240 nm to 280 nm.
Apart from the purification of drinking water, it is also used for water disinfection, industrial water disinfection, and surface disinfection.
The water flows through the inlet system, and after that, the water is exposed to UV light. There the reaction occurs where the DNA of microorganisms is altered. This DNA alteration curbs the capability of the organisms to replicate and grow further. This technology is so effective that no viruses, bacteria, algae, cysts, and many other microorganisms. This process is often termed water sterilization.
What is the life of UV lamps?
UV lamp has a limited life, and after at least one year, it has to be replaced. But it depends upon the quality of water that is going to pass through it. If the water is not adequately treated and turbidity levels are low, the UV lamp has to be treated every six months. In case of high turbidity, the frequency levels may be increased.
UV lamps are not much costly. It requires only a small amount of investment. After that, a bit of maintenance is needed to keep the system going, and it produces water free of microbes.
