Disinfection 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) ...
متن کاملVolatile disinfection byproducts resulting from chlorination of uric acid: implications for swimming pools.
Cyanogen chloride (CNCl) and trichloramine (NCl3) are important disinfection byproducts in chlorinated swimming pools. However, some unknowns exist regarding the precursors of their formation. In this study, uric acid is shown to be an efficient precursor to formation of CNCl and NCl3. The molar yields of CNCl and NCl3 were observed to be as high as 44% (pH = 6.0, chlorine/precursor molar ratio...
متن کاملDisinfection byproducts in swimming pool water in Sanandj, Iran
The present study aimed to determine the concentrations of several disinfection byproducts (DBPs), including trihalomethanes (THMs), haloacetic acids (HAAs), and haloacetonitriles (HANs), in the public and private swimming pools in Sanandaj, Iran (n=16). Correlations between DBP levels with water quality parameters (free chlorine, pH, total organic carbon, temperature, number of swimme...
متن کاملEnhanced formation of disinfection byproducts in shale gas wastewater-impacted drinking water supplies.
The disposal and leaks of hydraulic fracturing wastewater (HFW) to the environment pose human health risks. Since HFW is typically characterized by elevated salinity, concerns have been raised whether the high bromide and iodide in HFW may promote the formation of disinfection byproducts (DBPs) and alter their speciation to more toxic brominated and iodinated analogues. This study evaluated the...
متن کاملCharacterization of soluble microbial products as precursors of disinfection byproducts in drinking water supply.
Water pollution by wastewater discharge can cause the problem of disinfection byproducts (DBPs) in drinking water supply. In this study, DBP formation characteristics of soluble microbial products (SMPs) as the main products of wastewater organic biodegradation were investigated. The results show that SMPs can act as DBP precursors in simulated wastewater biodegradation process. Under the exper...
