Source-separated urine : strategies for implementation in the United States / Laura Anthony. by Anthony, Laura Subjects Urine -- Analysis   Sanitary engineering   Toilets   Wastewater   Nutrients   Conservation.   MSEV Project. Description:  52 leaves : ill. ; 29 cm. Contents:  Thesis advisor: Steve Arant Committee members: John M. Hassler, Dr. Francis Mahuta Background -- Importance of research -- Research question -- Characteristics of urine -- General methods for urine nutrient recovery and treatment -- Needs of crops -- Methods of urine collection, storage, and distribution to end user -- Social concerns -- Design criteria -- Engineering design -- Life-cycle cost estimate -- Pollution prevention aspect -- Conclusions and recommendations. Source-separated urine presents an opportunity to reuse valuable nutrients -- nitrogen, phosphorus and potassium -- found in urine. The purpose of this report is to analyze the urine source-separation system and evaluate the possibility for implementation in the United States. The process has been researched and tested in various other countries, but has not been installed in the United States. Research was first conducted on case studies of source-separated urine, to analyze how other countries were implementing the system. Additionally, the characteristics of urine and needs of crops, specifically corn, were looked at and discussed. Finally, a theoretical case in the United States was evaluated and a life-cycle cost was found. Pollution prevention was also addressed. This report found that urine source-separation has been successfully conducted in other countries and could also be installed in the United States with a few technical adjustments. There is a 20-year payback period over the entire source-separation system, but with advances in toilet technology and increased costs of nutrient treatment, the payback could reduce dramatically. The technology and engineering behind the system are not likely to be problematic. Human acceptance and economic drivers of the urine source-separation system will likely be the larger problem.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .A58 2009 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
