Microbiology Biological treatment Arsenic oxidation Drinking water Molecular ecology Nitrification Ammonia oxidation Nitrification in drinking water distribution systems is a problem prevalent throughout the world, and it has become more pertinent since chloramination has become a popular disinfectant technique. Because nitrification requires ammonia, removing ammonia in source waters prior to treatment would benefit both the utility and consumers. Biologically active filtration is a well known technology in Europe but its reliability, and thus implementation, is questioned in the United States. In this study, natural microbial flora from a full-scale treatment plant in Greene County, Ohio was used to seed two pilot scale rapid sand filters. These filters were evaluated for their ability to oxidize ammonia-nitrogen. Molecular techniques, including 16S ribosomal RNA and amoA gene sequencing and denaturing gradient gel electrophoresis (DGGE) analysis, were used to phylogenetically identify and fingerprint the isolates. In addition to investigating nitrification, microbial arsenic oxidation was also investigated in pilot-scale filters. Chemical analysis and microbial ecology is compared and discussed in terms of operational changes and water chemistry. 2010-08-09 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1277154047 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1277154047 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
