Real-time water monitoring in Riddle, Oregon

October 6th, 2016

ONAMI portfolio company ZAPS Technologies’ LiquID Station is providing quality control feedback for the very forward-looking Riddle (ORR) Public Works Department, showing that its novel Hybrid Multispectral Analysis technology is an affordable fit for cities of all sizes.

A small town in Oregon has taken a creative and innovative approach to ensure optimal performance at its water treatment facility by using leading-edge real-time water monitoring technology, a vigilant mindset, and an eye to the future.

With an average flow of 0.1 million gallons per day the wastewater treatment plant serving city of Riddle, Oregon, may not be the largest in the nation, but for Public Works Director Eric Quinn its safe and efficient operation is of the highest priority. Since his arrival at the plant in 1988, Quinn has worked diligently to keep the facility and its staff up to date with the most current information and technological tools. He’s proud of the work they’re doing and eager to do it better.

“Operators must possess the moral fiber to do the very best they can in this current atmosphere of environmental sensitivity. It is our duty as one of the shepherds of the waters of the state, to use all the tools to the best of our abilities no matter what we are presented with. That is our challenge,” says Quinn.

ZAPS Technologies is a Corvallis, Oregon based company that provides high-precision optical instrumentation and services for real-time water quality monitoring and analysis. The company’s flagship product, the LiquID station, provides reagent-free, multi-parameter detection capability, and is rugged enough for exposed field installations.

To make these measurements, the LiquID station uses Hybrid Multispectral Analysis (HMA); an optical approach developed at ZAPS Technologies specifically for online monitoring. HMA uses a combination of in situ fluorescence, absorption, and scattering measurements in a single flow-cell to continuously characterize chemical bonding and molecular structure.

HMA is a unique combination of advanced optical, photonic, and statistical technologies applied to the challenge of providing synchronized high frequency data for complex water types. Such information is required to control and monitor treatment processes in real time. HMA is a ‘green’ technology in that it eliminates reagents and standards for sampling, eliminates sample preparation and storage, and requires only 72 watts to operate. The HMA methodology was developed through support in part by the US Environmental Protection Agency, Office of Naval Research (ONR), Oregon State University, and the Oregon Nanoscience and Microtechnologies Institute (ONAMI).
