Use of pulsed-UV processes to destroy NDMA
Autor: Marshall K. Davis, Donald S. Remer, Sun Liang, Joon H. Min, James F. Green
Publikováno v: Journal - American Water Works Association. 95:121-131
Bench-scale experiments were conducted to determine the effectiveness of using pulsed-ultraviolet (UV) irradiation and pulsed-UV/hydrogen peroxide (H 2 O 2 ) processes to destroy N-nitrosodimethylamine (NDMA). The effects of various UV and H 2 O 2 do

MTBE in Southern California water
Autor: Richard F. Losee, Melissa S. Dale, Bart Koch, Marshall K. Davis, Eric W. Crofts
Publikováno v: Journal - American Water Works Association. 92:42-51
Methyl tertiary butyl ether (MTBE) is a common fuel oxygenate used in motor vehicle fuels to control emissions and boost octane. It is more water-soluble than other fuel constituents and does not adsorb well to substrates such as soil. It can contami

Oxidation of MTBE by ozone and peroxone processes
Autor: Roy L. Wolfe, Richard S. Yates, Jeanne-Marie Bruno, Sun Liang, Marshall K. Davis, Leslie Soo Palencia
Publikováno v: Journal - American Water Works Association. 91:104-114
Initial pilot-scale investigations demonstrated that both ozone alone and a combination of ozone and hydrogen peroxide (known as peroxone) can remove methyl tertiary butyl ether (MTBE) from water sources used by the Metropolitan Water District of Sou

Laboratory Management: Facing the Challenges of the Future
Autor: Marshall K. Davis, Roy L. Wolfe
Publikováno v: Journal - American Water Works Association. 85:50-55
Most analytical work performed is for purposes of compliance monitoring on water, wastewater, and hazardous waste samples. When commercial laboratories are affiliated with consulting firms, some analyses may be conducted to support the firms' work in

Removal of dissolved organic carbon using granular activated carbon
Autor: Elaine W. Howe, John C. Crittenden, Marshall K. Davis, E. Marco Aieta, Kartik Vaitheeswaran, Michael J. McGuire, Carol H. Tate, David W. Hand
Publikováno v: Water Research. 27:715-721
Granular activated carbon (GAC) is used to reduce disinfection by-products by removing dissolved organic carbon (DOC). The optimum empty bed contact time (EBCT) for a single adsorber was determined and the influence of parallel bed operation on GAC u

The effects of ozonation and activated carbon adsorption on trihalomethane speciation
Autor: Lo Tan, Marshall K. Davis, Gary L. Amy
Publikováno v: Water Research. 25:191-202
Two surface water sources in the southwestern United States were studied in bench-scale experiments examining two trihalomethane (THM) precursor removal processes, activated carbon adsorption and ozone oxidation. Both source waters contained bromide

Evaluating GAC for Trihalomethane Control
Autor: Michael J. McGuire, John C. Crittenden, Carol H. Tate, Elaine W. Howe, Marshall K. Davis, E. Marco Aieta
Publikováno v: Journal - American Water Works Association. 83:38-48
The primary objectives of this study were to optimize granular activated carbon (GAC) treatment to meet more stringent trihalomethane (THM) standards, to estimate the costs of optimized GAC treatment, to identify by-products of the final disinfection

Autor: Michael J. McGuire, Marshall K. Davis, Sylvia E. Barrett
Publikováno v: Journal - American Water Works Association. 77:50-61
The Metropolitan Water District of Southern California recently changed its primary disinfectant from free chlorine to chloramines in order to help its member agencies control trihalomethanes (THMs). The effects of blending chloraminated and chlorina
