In the field of water purification and treatment, ultraviolet sterilization is considered to be one of the most effective water treatment disinfection methods, extending the life of treated water.

In this blog, we want to introduce the UV sterilizer and how it works in water treatment.

What is UV Sterilizer?

Ultraviolet (UV) sterilizers use ultraviolet germicidal irradiation (UVGI) as a sterilization method to break down microorganisms including pathogens, viruses, and molds. UV sterilizers require a wavelength of at least 253.7 nm for effective sterilization.

UV sterilization works by breaking down the DNA of microorganisms, destroying their ability to reproduce.

Furthermore, UV treatment of water is considered to be a safer, more environmentally friendly, and more cost-effective method of disinfection of industrial water.

How does UV Sterilization work?

UV sterilization is known as UV disinfection or ultraviolet germicidal irradiation (UVGI). UV light is divided into several different ranges: (near the visible range) UV-A, UV-B, UV-C, and Vacuum-UV (near the X-ray range.)

The UV-B range is what causes sunburn in humans. UV water purifiers use the UV-C range because of their germicidal ability. UV-C is short-wave ultraviolet radiation, in contrast to long-wave UV-A and UV-B, a type of ultraviolet light capable of breaking bonds in the DNA molecules of microorganisms.

The bactericidal effect is determined by the irradiation dose received by the microorganisms. If a UV sterilizer is used correctly, it is highly unlikely that any microorganisms will survive its action. The UV process is therefore considered to be the best choice for water disinfection and does not overheat the equipment.

Which industries can benefit from UV water treatment systems?

UV Sterilization system is more than just discharge lamps in pipes. Commercial UV water sterilizers, industrial UV water sterilizers, and residential UV water sterilizers are used in various industries such as:

Food and beverage industry

UV disinfection systems can help to achieve the quality of water as per specifications laid down by the FDA( Food and Drug Administration).

Bio-Pharmaceutical industry

Water used for pharmaceutical and medical projects and CIP(Cleaning in Place) should be free of pollutants such as ozone, chlorine, and bacterial substances.


Microbe- and pathogen-free water guarantees quality and extends the shelf life of cosmetics. It has become the first choice for the global cosmetics industry.

Wastewater Disinfection and Reuse

UV can help address water scarcity and the rising cost of fresh water, helping by treating wastewater in a third stage.

Centralized Drinking Water

UV Drinking Water Disinfection Systems are an easy, affordable solution to ensuring pure water at every tap in your home or office.

Swimming Pools

UV, a chemical-free technology, is a safer and more cost-effective method of sanitizing swimming pools

What are the benefits of UV Sterilizers?

Because UV water treatment is a chemical-free process, there is no need to deal with potentially dangerous chemicals, such as chlorine, and no chemical disinfection by-products. And UV disinfection is almost immediate.

  • Virtually all microorganisms are susceptible to Brother Filtration ultraviolet disinfection.
  • Continuous or intermittent disinfection can be provided without special attention.
  • The most cost-effective disinfection system in the market.
  • No chemicals are introduced so there is no chance of an overdose
  • UV sanitizes in seconds without any contact tank or hold time
  • It is Simple installation and maintenance.


UV sterilizers are highly effective in eliminating all microbial contamination present throughout the water. However, there must be sufficient exposure to the sterilizer’s UV light for proper disinfection to take place.

UV sterilizers are suitable for a wide range of uses, from drinking water in residential areas or small commercial businesses to large water sources throughout municipal areas and industrial facilities.

What about the periodic maintenance of the UV disinfection system?

There are certain instances that occur in which the water is not sufficiently pretreated and turbidity levels are insignificant. Routine inspection and cleaning can be done every 6 months. In cases of high turbidity and hardness, more frequent cleaning may be required.

Finally, UV lamps have a limited lifespan and must be replaced once worn out. In the event of premature lamp failure, a supervisory circuit will provide a signal to recommend replacement.
