Occurrence and control of nitrogenous disinfection by-products in drinking water--a review.
TLDR
A critical review of the occurrence and control of nitrogenous disinfection by-products is provided, finding that the sum of analysed halonitromethanes represented 3-4% of the mass of THMs on a median basis.About:

Halonitroalkanes, Halonitriles, Haloamides, and N-Nitrosamines: A Critical Review of Nitrogenous Disinfection Byproduct Formation Pathways
Amisha D. Shah,William A. Mitch +1 more
TL;DR: In this article, the formation pathways for nitrogenous disinfection byproducts (N-DBPs) associated with chlorine, ozone, chlorine dioxide, UV, and chloramine disinfection are critically reviewed.
Journal ArticleDOI
Formation, precursors, control, and occurrence of nitrosamines in drinking water: a review.
TL;DR: This review summarizes major findings over the last decade related to nitrosamines in drinking water, with a particular focus on N-nitrosodimethylamine (NDMA), because it is among the most widely detected nitrosamine in drinking waters.
Journal ArticleDOI
Precursors of nitrogenous disinfection by-products in drinking water--a critical review and analysis
TL;DR: It was calculated that for HANs and HAcAms, the concentrations of known precursors - mainly free amino acids are insufficient to account for the observed concentrations of these N-DBP groups, however, at least in some waters, a significant proportion of CNX and NDMA formation can be explained by known precurors.
Journal ArticleDOI
Comparison of Permanganate Preoxidation and Preozonation on Algae Containing Water: Cell Integrity, Characteristics, and Chlorinated Disinfection Byproduct Formation
TL;DR: The results suggest that permanganate is a better choice than ozone for controlling algae derived pollutants and disinfection byproducts after preozonation.
Journal ArticleDOI
Recent developments in environmental photocatalytic degradation of organic pollutants: the case of titanium dioxide nanoparticles—a review
TL;DR: In this paper, the authors explore and summarize recent efforts in the area of titania nanoparticle synthesis, modifications, and application for water treatment purposes, and conclude that Titania nanoparticles are intended to be both supplementary and complementary to the present water treatment technologies through the destruction or transformation of hazardous chemical wastes to innocuous end-products, that is, CO2 and H2O.

Formation of organic chloramines during water disinfection - chlorination versus chloramination
Wontae Lee,Paul Westerhoff +1 more
TL;DR: Comparison of three different disinfection schemes at water treatment plants indicated organic chloramine formation could lead to a possible overestimation of disinfection capacity in many chloraminated water systems that add chlorine followed by an ammonia addition to form monochloramine.
Journal ArticleDOI
Fate of effluent organic matter and DBP precursors in an effluent-dominated river: a case study of wastewater impact on downstream water quality.
TL;DR: The impact of treated wastewater discharges on downstream water quality was evaluated in an effluent-dominated stream in the Southwest USA, and changes in DBP formation potential along the river appeared to correlate with dissolved organic carbon and organic nitrogen concentrations and specific ultraviolet absorbance.
Journal ArticleDOI
Enhanced nitrogenous disinfection byproduct formation near the breakpoint: implications for nitrification control.
TL;DR: It is proposed that there are two nitrosamine formation pathways active in the breakpoint chlorination region: a relatively slow reaction of dichloramine with amine precursors in the presence of dissolved oxygen and a fast reaction involving reactive break point chlorination intermediates.
Journal ArticleDOI
Chemical and biological oxidation of NOM surrogates and effect on HAA formation
TL;DR: Findings indicate waters with high amino acid concentrations will be susceptible to raised HAA levels following AOP treatment and careful process selection for HAA control is required in such cases.
Journal ArticleDOI
Occurrence and removal of dissolved organic nitrogen in US water treatment plants
TL;DR: In this article, two seasonal sampling campaigns of raw and finished waters from 28 water treatment plants were conducted to investigate the occurrence and removal of dissolved organic nitrogen (don) in raw waters.
