Portland is a start-up company based in Oregon that is using solar technology to reduce E. coli, Salmonella and Listeria contamination in agricultural water. They have received a state grant to develop their passive treatment system, “Ray”.
According to Ken Vaughn, the commercialization director at Oregon Best (a supporter of the development of cleantech businesses), that while the idea of Portland-based Focal Technologies Innovative Solar Water Treatment System is not new, small scale efforts to purify water with similar technology have been expensive. He says that Ray is a promising clean technology that may be able to provide an inexpensive, large-scale solution to using solar energy in purifying water.
“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.
