Develop and perform bench-scale evaluations/demonstrations of an integrated process that allows for the recovery of both nitrogen (NH4) and phosphorus,Develop models (1) kinetic model for phosphorus recovery and (2) mass transfer model for ammonia recovery - that can be used to further scale-up the integrated process,Confirm the ability to reduce high total phosphorus levels in swine manure operations through its recovery as a valued, well-balanced product, with a goal of 95% recovery,Confirm the ability to reduce ammonium levels in a QW-P treated stream, after removal of the recovered phosphorus precipitate, the goal is 90% recovery,Identify potential market values of the phosphorus and ammonium recovered products to serve as a cost recovery mechanism, as well as the fully treated water, andEvaluate process economics to include annual operating costs, estimated capital costs, and Net Present Value, assuming a 5% discounted rate and 10-year life. These estimates will be developed with and without potential market value of recovered phosphorus and ammonium nutrients. T
