Ultraviolet Sterilization Systems In order for the disinfection with ultraviolet rays to take place fully, there should not be any sediment in the water. In order to ensure that the water to be disinfected with ultraviolet rays reaches the entire water with the required intensity, parameters such as sediment and turbidity must be removed from the water and enter the system clearly. Disinfection with Ultraviolet Systems is the process of neutralizing microorganisms without adding any chemical or oxidant to the water. Thanks to the ultraviolet lamp placed in a similar glass cover, the water entering the device is given a dosed UV RAID. These ultraviolet rays disrupt the DNA structure of the ultraviolet microorganisms and ensure them to be ineffective. In this way, an average disinfection efficiency of 99.9% can be achieved. Another issue to be considered about the Ultraviolet Systems is to place it as close to the system use as possible. In addition, the water coming out of the system should not enter a separate unit, being open to the atmosphere especially, and should be used without waiting. Periodic maintenance is very important to provide a good efficiency in the ultraviolet units. Quartz glass cleaning should be made periodically depending on the UV lamp change and raw water quality, once a year. If this cleaning is not made, it would reduce the UV radiation efficiency and the device efficiency would also decrease.
