VIQUA's LightWise Technology – A Smart Solution To A Common Problem

VIQUA, the world’s leading manufacturer of residential ultraviolet (UV) water disinfection systems, recently officially introduced its new LightWise technology. LightWise technology is featured in the VIQUA PRO series – the PRO10, PRO20, and PRO30 – for light commercial applications.

An industry first, LightWise allows the system’s electronic controller to automatically reduce lamp power during periods of no water flow. 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 per cent. This can more than double the amount of time between sleeve cleaning cycles.

“In many situations,” explains VIQUA General Manager Frank Profiti, “the most common problem affecting 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. Our LightWise technology controls the water temperature, which dramatically reduces the rate of sleeve fouling.”

In traditional UV systems, under no-flow conditions through the UV chamber, the water temperature increases. This causes an accelerated rate of calcium, magnesium, and iron deposits precipitating onto the quartz sleeve, which in turn decreases the level of UV transmittance and, most importantly, affects disinfection. Fouling eventually requires the sleeve to be cleaned.

While actual water usage may vary significantly in a twenty-four-hour period, conditions of no water flow typically account for as much as 60 per cent 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.

Benefits of LightWise Technology
Lower maintenance (Up to 60 per cent less maintenance)

• Decreases conditions that contribute to fouling and corresponding maintenance. · Increases time period between required maintenance.
• Eliminates the need for a complicated mechanical sleeve cleaning system.
• Fewer false alarms.

Lower Energy Consumption

• Estimated energy savings of 30 per cent (Typical two unit PRO20 installation uses 2800 kW/yr).

Lower Operating Temperature

• Maintains water temperature below 40 C (104 F) in no-flow conditions.
• Eliminates the need for hot water purging in no-flow conditions.

“The future of UV water disinfection will be shaped by great minds and innovation,” says Profiti. “Our team at VIQUA is raising the bar. Innovations like LightWise set the tone for more efficient, intelligent, reliable products to provide safe drinking water.”
