• Characterization of disinfection by-product precursors from Missouri streams 

    Mbonimpa, Eric Gentil (University of Missouri--Columbia, 2007)
    The NOM contained in drinking water sources reacts with Cl2 to generate THMs and HAAs. THMs and HAAs are regulated by EPA because they pose a health hazard. The nature of the DBP precursors is complex and not well understood. ...
  • Formation studies on N-nitrosodimethylamine (NDMA) in natural waters 

    Luo, Xianghua (University of Missouri--Columbia, 2006)
    N-nitrosodimethylamine (NDMA) is a chloramines disinfection by-product and probable carcinogen to human. The California state established a 10 ng/L action level for NDMA in drinking water. Analytical method of NDMA in ...
  • Management of disinfection byproduct production in small drinking water systems 

    Wulff, Lisa M. (University of Missouri--Columbia, 2011)
    Two groups of disinfection byproducts (DBPs) currently regulated in drinking water are trihalomethanes (THMs) and haloacetic acids (HAAs). The objective of this research was to better understand how the water treatment ...
  • Nitrification enhancement in lagoons using fixed film media 

    Srinivas, D.S.R.K. (University of Missouri--Columbia, 2007)
    Lagoons, commonly used in municipal wastewater treatment, are limited in their ability to treat wastewater due to limitations in the process and operational flexibilities. The small municipalities using lagoons are under ...
  • Nitrification performance of a modified aerated lagoon 

    Maguluri, Kanchana (University of Missouri--Columbia, 2007)
    The performance of a modified wastewater lagoon and the factors affecting the treatment process are discussed. This study was conducted over a period of twelve months at the Kingdom City, Missouri lagoon. A polyethylene ...
  • Occurrence and modeling of THMS and HAA formation in drinking water 

    Cheng, Jing, 1975- (University of Missouri--Columbia, 2007)
    Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the largest classes of disinfection by-products (DBPs) during chlorination in drinking waters. In this dissertation, the formation of THMs and HAAs in drinking ...
  • Removal of disinfection by-product precursors by activated carbon and MIEX® 

    Hanigan, David (University of Missouri--Columbia, 2011)
    The objective of this research was to investigate NOM removal with activated carbon and MIEX®. Hydrophilic (HPI), hydrophobic (HPO), and transphilic (TPI) NOM was fractionated and subsequent DBP formation from these fractions ...
