RayVio shows UV-C dosing as highly effective for water sterilisation

* RayVio-UV-charts.jpgRayVio, an advanced health and hygiene company, has published its latest application note detailing the company's ultraviolet dosing experiments proving the water sterilisation capability of RayVio's UV-C LEDs. Water safety is of particular concern in appliances and applications where water may stand for a period, be exposed to contaminants, or be turned into vapour and distributed through the air, as is the case with humidifiers.

"Three mW of UV-C light from a RayVio XE Series LED applied hourly for five minutes can keep stored water 'clean' indefinitely," reveals Dr. Doug Collins, CTO and VP of Engineering.

The first experiment, a side-by-side test of two clean water samples, showed that intermittent treatment (dosing) with RayVio's UV-C will keep clean water clean while water that isn't dosed with RayVio's UV-C light will have significant growth of bacteria.

The second experiment with two heavily contaminated water samples demonstrated that contaminated water exposed to periodic doses of UV-C light from RayVio's UV LED can be decontaminated with a few doses of UV light over the span of several hours.

"Water safety is on everyone's mind because of its potential as a breeding ground for bacteria and viruses and the ease with which infections can be spread at homes and in offices," says Dr. Collins. "Clearly, our XE Series UV-C LEDs can keep clean water from becoming contaminated with germs and clean already contaminated water."

Operational lifetime of UV-C LEDs is critical to most applications and particularly those that affect people's health and hygiene. With RayVio's XE and XP Series UV-C LEDs lifetimes approaching 10,000 hours, the value and longevity of many consumer applications continues to increase as well.

Disinfecting flowing water and sterilising medical instruments requires the highest possible levels of UV-C LED performance. RayVio is now in volume production of the industry's highest performing UV-C LED, the XP Series, with 70mW of output. The company remains on-track for delivering 100mW performance from a single device in the near future.
