UV disinfection is an effective method for combating microbiological contamination in water. It uses ultraviolet light to destroy harmful microorganisms such as bacteria, viruses and protozoa without leaving behind any chemical additives or residues.

How UV disinfection works

UV disinfection is based on the application of UV-C light with a wavelength of about 254 nanometers. This light penetrates the DNA of microorganisms and destroys their structure, which prevents replication and renders the microorganisms harmless.

  1. UV lamp: A UV lamp is integrated into the water pipe system.
  2. Irradiation: The water flows through a chamber in which it is irradiated with UV light.
  3. Disinfection: UV radiation deactivates the DNA of microorganisms and prevents them from multiplying.

Advantages of UV disinfection

  1. Chemical-free: No chemical additives, therefore no residues or taste changes in the water.
  2. Effective: High efficacy against a wide range of microorganisms, including chlorine-resistant pathogens such as Giardia and Cryptosporidium.
  3. Fast: Immediate disinfection as soon as the water is exposed to UV radiation.
  4. Environmentally friendly: No harmful byproducts, gentle on the environment.
  5. Low maintenance: Low maintenance, only regular replacement of the UV lamp is required.

Areas of application

  • Households: UV disinfection systems ensure microbiologically safe drinking water.
  • Commercial: In the food and beverage industry to prevent contamination.
  • Industry: Water treatment in processes that require high-purity water, such as pharmaceuticals and electronics manufacturing.
  • Municipalities: Ensuring drinking water quality in municipal water supply systems.

Installation and maintenance

  1. Installation: UV disinfection systems are usually installed as the last stage of water treatment to ensure that the water is free of particles that could block UV radiation.
  2. Maintenance: Regularly replace the UV lamp (every 6-12 months depending on the model) and occasionally clean the quartz protective cover to ensure optimal efficiency.

Conclusion

UV disinfection is a safe, effective and environmentally friendly method of water treatment suitable for both domestic and industrial applications. It ensures microbiologically safe water without the use of chemicals and with minimal maintenance.
