WERF begins research on manure resource recovery
By Marg Land
June 3, 2014, Alexandria, VA – The Water Environment Research Foundation (WERF) will begin its third project under the U.S. Environmental Protection Agency funded National Research Center for Resource Recovery and Nutrient Management with research that explores manure resource recovery.
The project – Manure Resource Recovery: Co-Digestion with Low-Cost Ammonia Stripping (STAR_N3R14) – will be led by a team of researchers from the University of Washington and Washington State University.
This study will demonstrate the feasibility of using low-cost/chemical ammonia stripping to recover ammonia from wastewater and manure. The recovered ammonia will then be provided as fertilizer. Ammonia stripping is a known technology for nitrogen removal, but adoption for the management of animal waste has been slow due to high costs.
Demonstrations will take place at dairy cow facilities in Washington and Wisconsin, and at a poultry operation in Ohio. Application of this technology will contribute to improvements in nutrient-impaired water systems, reduction in greenhouse gas emissions, and other environmental and community development goals.
