Why Does Your UV Water Purifier Need Cleaning So Often?

One of the biggest problems with UV water disinfection is the buildup of minerals on the quartz sleeve that surrounds the UV lamp. This buildup—caused by calcium, magnesium, and iron in the water—blocks UV light, making the system less effective.The problem gets worse when there’s no water flowing through the system. When water sits still, the UV lamp heats it up, sometimes reaching 55°C (131°F). This heat speeds up mineral deposits on the sleeve, meaning you’ll have to clean it more often.Since water isn’t flowing for as much as 60% of the day in most homes, your UV system is likely dealing with this issue regularly. The good news? Regular maintenance and choosing a system with features like automatic cleaning or temperature control can help keep things running smoothly.

VIQUA’s Solution

VIQUA’s new LightWise technology allows the controller to reduce lamp power during periods of no water flow, leading to estimated energy savings of 30%. By adjusting the lamp power, water temperature is maintained below 40˚C (104˚F), and the rate of sleeve fouling is consequently reduced by as much as 60%. This can more than double the amount of time between sleeve cleaning cycles.
