Interpretive Summary:

Technical Abstract: There are many aspects of animal residuals such as waste characteristics, operator involvement, regulations, and fiscal resources that are distinctly different than the sewage industry and require treatment technology developed specifically for animal waste systems. Our approach was to improve or retrofit existing liquid treatment systems so that volatile solids and organic nutrients are separated from the fresh manure and transported and treated with a variety of technologies to generate value-added products. The remaining liquid was treated on the farm. A variety of biological, physical or chemical processes can be used effectively to achieve specific nutrient management goals at the farm. In this paper we describe new technologies developed for treatment of nitrogen in swine manure. These include liquid-solid separation with polymer,enhanced nitrification and denitrification using immobilization techniques, anaerobic ammonium oxidation (anammox), and total system integration.
