The effect of inorganic precursors on disinfection byproduct formation during UV-chlorine/chloramine drinking water treatment.
Ultraviolet (UV) disinfection is being increasingly used in drinking water treatment. It is important to understand how its application to different types of water may influence finished water quality, particularly as anthropogenic activity continues to impact the quality of source waters. The objective of this study was to evaluate the effect of inorganic precursors on the formation of regulat...
متن کاملEvaluation of the relationship between bulk organic precursors and disinfection byproduct formation for advanced oxidation processes.
Advanced oxidation processes (AOPs) are gaining traction as they offer mineralization potential rather than transferring contaminants between media. However, AOPs operated with limited energy and/or chemical inputs can exacerbate disinfection byproduct (DBP) formation, even as precursors such as dissolved organic carbon, UV254, and specific UV absorbance (SUVA) decrease. This study examined the...
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 کاملDetermining sources of dissolved organic carbon and disinfection byproduct precursors to the McKenzie River, Oregon.
This study was conducted to determine the main sources of dissolved organic carbon (DOC) and disinfection byproduct (DBP) precursors to the McKenzie River, Oregon (USA). Water samples collected from the mainstem, tributaries, and reservoir outflows were analyzed for DOC concentration and DBP formation potentials (trihalomethanes [THMFPs] and haloacetic acids [HAAFPs]). In addition, optical prop...
متن کاملDisinfection byproduct formation in swimming pools
The fate of organic nitrogen and carbon introduced into a swimming pool by pool users has been studied using a 2.2 m model pool. The study made use of a body fluid analogue, containing the primary endogenous organic amino compounds, and a soiling analogue represented by humic acid. The system was used to examine the effect of organic loading and organic carbon source (i.e. amino or humic acid) ...
