The different components of a UV disinfection system

Posted by Dardy Lacy on April 19th, 2023

UV disinfection systems have different components that make them work efficiently to disinfect water. Access to clean drinking water has been a necessity of humankind and it can be achieved through various water disinfection methods such as chlorination, filtration, UV disinfection and so on. Among the different methods available, UV water disinfection has emerged as the most effective water treatment method.

Amongst other water cleaning technologies, the UV water disinfection system is the most effective. It is a disinfection technology that uses invisible light -UV radiation to disinfect water and kill microorganisms. As this technology is extensively used, it is crucial to understand its functions and components.The system features four fundamental components that play an important part in the disinfection of water. The details of the components are as follows.

Reactor chamber

This is an enclosed structure that is made of stainless steel. The reactor chamber is the casing that encloses the other components of the system. The whole process of purification of water happens inside the reactor chamber. Depending on the needed flow rate of the system, the chambers come in different port sizes and shapes. Irrespective of the aesthetics of the chambers, all the chambers function the same – they enclose and support the assembly.

UV lamp

Being a part of the disinfectant system, the lamp is the most important component that a water solutions company places in the disinfection system. It is installed in the system to radiate the germicidal wavelength of the UV-c for disinfection. UV lamps have mercury that may pronounce hazards to people, however, it is present in a very small quantity.

Just like regular bulbs, UV lamps are fitted with filaments to produce an electric current. The current heats up the mercury, which evaporates and remains in the air inside the UV lamp. The evaporated mercury produces electric arcs, to produce UV radiations of different intensities to treat water. There are different types of lamps. These types include standard UV lamps, high-output UV lamps, and amalgam UV lamps.

Standard lamps are low-pressure lamps that are used in domestic disinfection devices. On the other hand, amalgam UV lamps are mercury amalgam lamps that increase the intensity of UV radiation using vaporized mercury. They are used in commercial systems. High-output UV lamps are low-pressure lamps. They are used for high flow rates and they form lower footprints. They are used for moderate or high-capacity water disinfection applications.

Controller units

A controller unit is a control unit that helps maintain the electricity output of the UV lamp. The radiation’s intensity is varied based on the supply of electricity offered by the control unit.

The quartz sleeve

This is another component of UV disinfection systems. It offers protection for the UV lamp. The UV lamp is inserted into this tube. The tube is a long cylindrical glass tube that helps to keep it safe from the water flow and ensure the efficient functioning of the disinfection system.
