UV Systems

UV (ultraviolet) systems are an effective method for water disinfection, meaning the elimination or reduction of pathogenic microorganisms such as bacteria, viruses, and protozoa. This process is based on the ability of ultraviolet radiation to break down the DNA or RNA of microorganisms.

Source of Ultraviolet Radiation: UV systems for water disinfection use UV lamps, usually mercury lamps, which emit ultraviolet radiation primarily at a wavelength of 254 nanometers (nm). This wavelength is particularly effective in damaging the DNA or RNA of microorganisms.

Water Passage: Water passes through a container or channel where it is exposed to UV radiation. The contact of water with UV radiation must be sufficient to ensure the appropriate dose of radiation for disinfection.

Operating Conditions: The effectiveness of UV radiation depends on many factors, such as the clarity of the water, the presence of other chemical substances that may absorb or scatter the radiation, and the intensity and duration of exposure to UV radiation.

Maintenance and Lamp Replacement: UV lamps have a limited lifespan and need to be replaced periodically to maintain disinfection effectiveness. Additionally, the system must be regularly maintained to avoid the buildup of salts or other contaminants that could reduce water permeability to UV radiation.

Advantages: It is an environmentally friendly method since it does not use chemicals and does not produce hazardous by-products. It is also quick and can eliminate a wide range of microorganisms.
