VIQUA’s new LightWise™ technology allows the system’s electronic controller to automatically reduce lamp power during periods of no water flow, reducing the rate of sleeve fouling by up to 60%, and providing estimated energy savings of 30% compared to standard PRO systems. 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 cleanings in the sleeve cleaning maintenance cycle.
In many situations, the most common problem affecting ultraviolet (UV) water disinfection is the fouling of the quartz sleeve which surrounds the UV lamp. The rate of sleeve fouling is influenced by water temperature, water flow, and water quality – specifically the concentrations of calcium, magnesium, and iron in the water, which are the most common constituents that lead to sleeve fouling. Under no-flow conditions through the UV chamber, the water temperature increases, which causes an accelerated rate of calcium, magnesium, and iron deposits precipitating onto the quartz sleeve. This decreases the level of UV transmittance and eventually requires the sleeve to be cleaned. While actual water usage may vary significantly in a 24-hour period, conditions of no water flow typically account for as much as 60% of the day. During this time, the UV lamp heats the water, resulting in water temperatures as high as 55˚C (131˚F) in the chamber and significantly increasing the rate of sleeve fouling.
