Organic Chloramine Formation and Influence on Disinfection Efficacy and Nitrification
Review the detection methods for organic chloramine described in the literature Evaluate the formation of organic chloramine from reactions between extracellular polymer substances (EPS), a component of biofilms, and disinfectants (free chlorine or monochloramine) Evaluate the formation of organic chloramine by reaction between heterotrophic plate count (HPC) bacteria (as planktonic bacte...
متن کاملDissolved organic nitrogen uptake by seagrasses
We examined the ability of seagrasses to take up dissolved organic nitrogen (DON) with leaves (in situ) and roots (laboratory) in an oligotrophic tropical offshore meadow in Indonesia using 15N-labeled nitrogen (N) substrates. We compared the uptake of urea and amino acids with that of ammonium (NH z4 ) and nitrate (NO { 3 ) and determined uptake kinetics of amino acids for the seagrasses Thala...
متن کاملVolatile disinfection byproduct formation resulting from chlorination of organic-nitrogen precursors in swimming pools.
Clinical studies have documented the promotion of respiratory ailments (e.g., asthma) among swimmers, especially in indoor swimming pools. Most studies of this behavior have identified trichloramine (NCl3) as the causative agent for these respiratory ailments; however, the analytical methods employed in these studies were not suited for identification or quantification of other volatile disinfe...
متن کاملEffects of metal ions on disinfection byproduct formation during chlorination of natural organic matter and surrogates.
The effects of calcium, cupric, ferrous and ferric ions on the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) were investigated using natural organic matter (NOM), small molecular weight NOM surrogates and natural water samples. The results showed that the effects were greatly dependent on the disinfection byproduct (DBP) precursor structure and molecular weight, and metal ions...
متن کاملInfluence of nitrogen source on NDMA formation during chlorination of diuron.
N-Nitrosodimethylamine (NDMA) is formed during chlorination of water containing the herbicide diuron (N'-(3,4-dichlorophenyl)-N,N-dimethylurea) but formation is greatly enhanced in the presence of ammonia (chloramination). Groundwater impacted by agricultural runoff may contain diuron and relatively high total nitrogen concentrations; this study examines the impact of the nitrogen form (ammoniu...
