Sensor Electronic Technology, Inc. (SETi) and Cascade Designs, Inc. of Seattle, have jointly developed UV LEDs for commercial, military and disaster relief/humanitarian applications.

SETi’s germicidal UV LEDs will provide potable water to small groups from any source of fresh water anywhere.

Germicidal UV LEDs are a new technology that offer an alternative to mercury lamps or chemical treatment and enables a compact, lightweight and mechanically robust disinfection solution that can stand up to the rigors of military and humanitarian use and, when powered with an alternative energy source, can offer a sustainable source of drinking water for many months.

Through a development program funded by the National Science Foundation (NSF), SETi has already successfully demonstrated the use of its germicidal UV LEDs in a bench top disinfection chamber.

The collaborative effort with Cascade Designs will further this work and lead to the development of the first multi‐stage UV LED‐based water purification system.
