UV disinfection is a method that uses ultraviolet light to kill or inactivate harmful microorganisms, such as bacteria and viruses. This process works by damaging the DNA or RNA of these pathogens, preventing them from reproducing and causing infections. It is commonly used in water treatment, air purification, and surface sanitation. This technology is effective and environmentally friendly, as it does not rely on chemicals. UV disinfection systems can be found in hospitals, laboratories, and even in household devices. By utilizing UV-C light, which has a specific wavelength, these systems can provide a reliable way to enhance hygiene and safety.
