Centrisys Corp. Team Named Winner Of EPA's Nutrient Recycling Challenge

National award promotes effective solutions to manure nutrient management

Centrisys Corporation, a leading North American manufacturer of dewatering and thickening centrifuges, announced recently& that it has been named a winner of the U.S. Environmental Protection Agency (EPA) Nutrient Recycling Challenge. The competition challenges companies worldwide to develop technological advancements that recycle nutrients from livestock manure more effectively. The recognition further solidifies Centrisys’ place as a global market leader in manure management solutions.

Livestock producers manage over one billion tons of animal manure annually in the United States. Recognizing the need to accelerate products that address more effective management of this issue, the EPA created the Nutrient Recycling Challenge. Out of 75 submissions from companies worldwide, 34 were chosen to continue on to the design phase, and the Centrisys team was ranked as one of the top four winners.

Centrisys’ winning paper was titledRemoval of Dissolved Nitrogen and Phosphorus from Livestock Manure by Air Stripping,and was developed in collaboration with CNP-Technology Water and Biosolids Corp. To maximize nutrient removal from the liquid fraction of manure, the team proposed treating anaerobically digested swine manure withAirPrex struvite precipitators before being dewatered with a decanter centrifuge. AirPrex is a CNP technology that utilizes CO2stripping to convert the dissolved fraction of phosphorus and nitrogen into solid fertilizer struvite.

“Solid separation is the primary means of managing nutrients in livestock manure and Centrisys has been setting a standard for effective solid separation,” said Hiroko Yoshida, Senior R&D Engineer and project leader. “We’re proud to apply more than a decade of engineering knowledgein solids separation to manure management– helping livestock producers by developing reliable nutrient managementsolutions.”

Since 1987, Centrisys has been a leading global innovator and manufacturer of decanter centrifuges, dewatering systems and process technologies for dewatering and water / solids separation in municipal, agriculture, and industrial applications. Centrisys introduced the industry’s first manure waste specific application for decanter centrifuges in the mid-2000s after extensive application and testing in dairy operations throughout the U.S. Compared to traditional slope screen filtration, which separates 20-25 percent of the solids, decanter centrifuges remove 65 percent, or three times as much as a typical separation system. Centrisys is the only U.S. manufacturer of decanter centrifuges for municipal water and wastewater applications.
