WMAO Water Luncheon

Creating Value from Waste: Results of a Nutrient Recovery Pilot for the City of Columbus

WHEN: April 16, 2013 – 11:30am-1:00pm
WHERE: Wilma H. Schiermeier Olentangy River Wetland Research Park, Heffner Building, Columbus, OH (map)

The City of Columbus has evaluated the application of Ostara’s Pearl® Nutrient Recovery Process to recover nutrients and prevent struvite scale formation at the Southerly WWTP. They have also evaluated a similar application of the Multiform Harvest Nutrient Recovery System at the Jackson Pike WWTP. These processes are based on the initiation and control of struvite precipitation within an upflow fluidized bed reactor, utilizing nutrients like phosphorus and ammonia already present in wastewater dewatering operations. The rate of struvite formation is controlled in the process so that a range of products can be produced, ranging from a soft, sandy consistency up to a high quality product with desired physical properties (size, hardness, purity etc.), which can then be sold as fertilizer.

WMAO Water Luncheon – NEW LOCATION

Low-cost Treatment of Turkey-processing Wastewater

WHEN: January 15, 2013
WHERE: Wilma H. Schiermeier Olentangy River Wetland Research Park, Heffner Building, Columbus, OH (map)

Over $10 million dollars has been saved by an Ohio meat processor by treating their wastewater in a new way. A sand bioreactor system was developed based on research conducted at The Ohio State University. This university/industry partnership has saved jobs, money and is
protecting the environment with effluents exceeding the quality of conventional treatment systems. Quiet, clean and simple are the best words to describe the appearance of the new sand bioreactor system constructed at the meat processing facility. Some people might mistake the
treatment system for a park. No odor is a feature neighbors most appreciate.

41st Annual WMAO Conference

100 Years of Watershed Events

WHEN: November 14 & 15, 2012
WHERE: Quest Conference Center, 8405 Pulsar Place, Columbus, OH 43240 (map)

The Ohio water management community is familiar with how land divides the flow of water into watersheds. Likewise, our most significant shared experiences often alter the flow of history. Pearl Harbor, the Moon landing, and the fall of the Berlin Wall are all recognized as important watershed events.

Ohio has experienced many watershed events over the past 100 years that have advanced how we manage water resources. The 1913 Flood was so great it marks the beginning of our 100-year timeline, but many have followed. The Cuyahoga River fire of 1969 was a catalyst for the Clean Water Act; and Louis Bromfield of Malabar Farm wrote Pleasant Valley in 1945, inspiring soil and water conservation throughout the U.S. In fact, almost everything we do as water resource professionals today can be traced back to some similar shift.

We will highlight these turning points by asking each presenter to include a brief introduction to their presentation describing the watershed event most pivotal to their work today. In this way, we will reflect on the past, not to dwell there, but to remind us that the dramatic events of today hold within them opportunities that will shape tomorrow.

Keynote Speaker at 2012 WMAO Conference

The Great Dayton Flood of 1913 (Images of America: Ohio)WMAO is hosting its 41st annual conference titled “100 Years of Watershed Events” on November 14 and 15, at the Quest Conference Center in Columbus. The keynote speaker will be Trudy Bell (, a science journalist and independent scholar with a master’s degree from New York University in the history of science and American intellectual history. She has written more than a dozen books and 400 articles about science, engineering, exploration, and history. Since 2003, she has visited archives in 15 states researching the 1913 storm system, the flood, and its consequences.

Here is a book description of Trudy’s The Great Dayton Flood of 1913 (Images of America: Ohio)” on

“Beginning on Easter Sunday, March 23, 1913, torrential rains across the Midwest dropped a record three months of rainfall in four days. Floodwaters funneled down Ohio’s Miami Valley into the heart of the vibrant industrial city of Dayton. Levees burst, houses were swept away, and downtown was gutted by fires blazing from broken gas mains. At the end of Easter week, nearly 100 Daytonians had perished, and tens of thousands more were left homeless and destitute—a tragedy that made banner headlines in newspapers nationwide. Out of Dayton’s ashes and mud rose fierce public resolve never again to suffer such destruction. The Great Dayton Flood of 1913 reproduces some 200 astounding photographs from the collections of the Dayton Metro Library and the Miami Conservancy District and the archives of the National Cash Register Company at Dayton History. They portray the terrifying flood, monumental destruction, heroic rescues, and compassionate leadership that occurred during the disaster and its immediate aftermath, as well as the pioneering flood-control engineering that has kept Dayton safe ever since.”

Please consider joining us at the 41st annual conference to hear from Trudy Bell and many more.
