Water Disinfection Using an Ultraviolet Lamp

Alongside various filtration media, an ultraviolet water lamp provides a high level of water purification from different types of contaminants. An ultraviolet disinfection unit treats drinking water supplied from boreholes and wells by eliminating pathogenic microorganisms and microbiological contaminants.

Why Is Ultraviolet Water Treatment Necessary?

After chlorination at water treatment plants, water should not contain viruses or bacteria. However, during distribution to houses and apartments through water supply pipelines, it may become recontaminated. Disinfection is also required when supplying water from private boreholes, as it may contain microorganisms. In such cases, an ultraviolet water lamp disinfects the water without the use of chemical or other reagents, ensuring a high level of purification quality and safety.

Design and Operating Principle of an Ultraviolet Lamp

Ультрафіолетовий фільтр складається з 3 елементів:

1. Циліндричний металевий корпус.
2. Бактерицидна лампа.
3. Кварцова трубка.

As water passes through the system, it is exposed to ultraviolet radiation generated by the UV lamp. This radiation destroys the structures of microorganism cell membranes, which leads to their sterilization.

Application Areas

Easy to maintain and relatively inexpensive, an ultraviolet water lamp is intended for use in the following areas:

• disinfection of drinking water supplied through water supply networks;
• treatment of artesian water;
• disinfection of well water.

Advantages of Ultraviolet Water Disinfection

It should be noted that an ultraviolet water lamp belongs to post-treatment systems. It effectively disinfects water only after large particles and impurities that block ultraviolet radiation have been removed.

Ultraviolet water treatment offers several advantages:

• water retains a natural taste and color;
• ultraviolet filters do not require high operating costs;
• a modern ultraviolet water lamp not only neutralizes microorganisms and viruses but also prevents their future development and reproduction;
• the filters demonstrate high treatment efficiency;
• ultraviolet radiation is effective against many known pathogenic microorganisms, including typhoid and cholera pathogens, dysentery bacilli, Escherichia coli, salmonella, and influenza viruses.

It should be emphasized that an ultraviolet water lamp is not a universal purification solution, as some microorganisms are resistant to UV radiation.

Selection of a UV Filter

When selecting an ultraviolet lamp for water treatment, the following factors must be taken into account:

• the required level of purification quality;
• water flow rate and temperature;
• the type of pathogenic organisms identified in the water.

In addition, it should be considered that UV lamps respond differently to water temperature. Low-pressure lamps are intended for installation in systems with water temperatures ranging from +15 to +20 °C, while medium-pressure UV emitters are used in systems with temperatures of up to +85 °C.

For effective purification, an ultraviolet water lamp must be selected with regard to the UV dose. This information should be provided in a calculation table indicating the types of pathogenic organisms to be eliminated and the corresponding radiation intensity of the lamp.
