Milorganite is a dry granulated lawn fertilizer. As more and more municipalities produce marketable fertilizer from wastewater treatment byproducts, the market for Milorganite and other biosolids is becoming more competitive Developing alternative markets for wastewater treatment byproducts is both environmentally and economically attractive. A treatability study was conducted to establish the efficacy of Milorganite as a nutrient source in the remediation of soil contaminated with diesel fuel. The study was done by comparing the performance of Milorganite to that of another granulated lawn fertilizer. Test chambers were constructed and the experiment designed following the guidelines established for the soil remediation technology of Biopiles. An additional goal of the study was to define a method that could be repeated with other contaminants using Milorganite as the nutrient source. The study results indicate that Milorganite may indeed prove useful for this purpose. A 95-96% reduction in Diesel Range Organics (DRO) was achieved over the 12 weeks of study. The results also indicate that when Milorganite is used, there is a synergistic effect between degradation of the contaminant and metabolism of the nutrient source. When degradation rates were computed from respiration test data based on the equation derived for metabolism of the contaminant, DRO results derived from respiration testing were found to agree well with those obtained from analytical testing.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .E35 2000 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
