Solar-Activated Stormwater Treatment

Puralytics: Lily pads

An Oregon BEST Commercialization Grant is helping Beaverton, Ore. startup, Puralytics, team with researchers at Oregon State University’s Institute for Water and Watersheds (IWW) to advance a floating, solar-activated stormwater treatment device that could be deployed in retaining ponds or ditches along roadways and parking lots to keep contaminants from reaching streams.

The company is incorporating the nanotechnology-coated mesh it uses in other products into large "lily pads" that float a few inches below the surface of standing stormwater. The new product could also be used to pre-treat stormwater, helping reduce overflow situations at municipal treatment facilities during severe weather events.

The OSU research team, led by Oregon BEST Member Faculty Todd Jarvis, will evaluate the overall concept of the new system, establish key design parameters, generate third-party test data, and construct artificial ponds or tanks that can be closely controlled and monitored during testing of the prototypes.

“Todd and his team at OSU are great partners, and they have the analytical horsepower to provide the third-party testing and data our company needs,” said Mark Owen, CEO of Puralytics. “One of the challenges for a small company is that you don’t have the analytical equipment or the funding to pay for third-party validation, so Oregon BEST is really filling that gap. Without this grant and Oregon BEST’s connections, this development work would have been significantly delayed."
