Oregon company using solar technology to kill pathogens in water

State research investors with Oregon BEST, a supporter of the development of cleantech businesses, believe Portland-based Focal Technologies innovative solar water treatment system has a great deal of promise.

Ken Vaughn, commercialization director at Oregon BEST, says that while the idea is not new, small-scale efforts to purify water have been expensive. He calls “Ray” a “promising clean technology” that could provide an inexpensive, large-scale solution to harnessing solar energy in cleaning up water, reports Food Safety News.

“So it looks like Focal Technologies has a new product that they’ve been developing over a number of years that’s really a fundamentally new technology that harnesses the power of the sun to provide a cost-effective way to treat wastewater,” Vaughn said.

The passive solar treatment system
Company officials say that two proven technologies are incorporated into the solar concentrating system, concentrated solar power, and the sun’s ability to clean up waste. Ray can break down agricultural waste as well as industrial chemicals, including cyanide and glycol.

Focal Technologies’ Ray technology works much like utility-scale solar power projects, concentrating solar energy. The big difference is that Ray uses that concentrated energy to purify water instead of generating electricity. Ray uses an eight-foot diameter solar concentrating lens, combined with a reaction chamber where effluent is exposed to as much as 10,000 BTU per hour and 4,000 WM² of ultra-violet energy.

“Our system can break down a wide range of contaminants, but we are initially focused on remediating E. coli and other harmful bacteria in human or animal waste streams,” said Eric Steinmeyer, CEO, and president of Focal Technologies.

Steinmeyer explains that Ray is not an “offset or efficiency boost” for processes that are already in place. Rather, by focusing the sun directly at an application, the technology can achieve results that fossil fuel systems can’t touch, especially in remote locations.

And that is one of the selling points of this innovative system. It is inexpensive and mobile, meaning it can be easily moved to any location, from developing countries for micro sewage treatment, to dairies for the treatment of effluent before it is allowed to run off into streams, and to purify wash-water for produce as mandated by new USDA/FDA standards.

The $210,000 grant from Oregon BEST will be used to support research at Oregon State University to study Ray’s use on animal waste at an organic dairy, where testing has already started.

We are deeply saddened to announce the passing of our dear friend Karen Graham, who served as Editor-at-Large at Digital Journal. She was 78 years old. Karen's view of what is happening in our world was colored by her love of history and how the past influences events taking place today. Her belief in humankind's part in the care of the planet and our environment has led her to focus on the need for action in dealing with climate change. It was said by Geoffrey C. Ward, "Journalism is merely history's first draft." Everyone who writes about what is happening today is indeed, writing a small part of our history.
