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.
