• 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)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Two groups of disinfection byproducts (DBPs) currently regulated in drinking water are trihalomethanes (THMs) and haloacetic acids (HAAs). The objective ...
  • Nitrification enhancement in lagoons using fixed film media 

    Srinivas, D.S.R.K. (University of Missouri--Columbia, 2007)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lagoons, commonly used in municipal wastewater treatment, are limited in their ability to treat wastewater due to limitations in the process and ...
  • 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)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the largest classes of disinfection by-products (DBPs) during chlorination 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 ...
