Ultraviolet (UV) water treatment systems use specialized lamps that emit UV light at a wavelength designed to disrupt the cellular function of microorganisms. This light damages the DNA of bacteria, viruses, and other pathogens, preventing them from reproducing or causing infection. Because UV treatment neutralizes these organisms without chemicals, it offers a clean, safe, and low-maintenance solution for water disinfection. Once installed, the UV lamp operates continuously, disinfecting water around the clock with only minimal annual maintenance required.

Since UV light travels in a straight line and doesn't penetrate solids or shadows, prefiltration is essential. Removing sediment, silt, and other particles ensures the UV light can effectively reach and treat any microorganisms present. Additionally, minerals found in hard water can accumulate on the quartz sleeve that protects the UV lamp, potentially reducing its effectiveness. In areas with hard water, a water softener is recommended as part of the pretreatment process.

For water drawn from natural sources, professional testing and proper treatment are strongly recommended before it's used for drinking, cooking, bathing, or recreational purposes. UV disinfection provides a dependable, chemical-free, and environmentally responsible method for treating water and protecting against microbiological contaminants.
