Available in PDF, EPUB and Kindle. Book excerpt: Drinking water disinfection has markedly reduced diseases causes by waterborne pathogenic microorganisms. However, an unintended consequence of disinfection and/or oxidation processes is the generation of disinfection byproducts (DBPs) which are formed from the reactions of disinfectants/oxidants with water matrix components. This volume of the Comprehensive Analytical Chemistry Handbook presents recent advances about the formation, identification, and quantification of inorganic and organic DBPs during oxidative processes. The book begins with a first chapter reviewing the most recent non-targeted screening approaches and workflows to characterize DBPs using low-, high-, and ultra-high-resolution mass spectrometry. The second chapter discusses the analysis of inorganic chloramines in waters using on-site and/or in-lab analytical methods. The third chapter provides an overview of the current knowledge about the mechanisms of chlorine dioxide reactions and byproducts formation. The fourth chapter presents some fundamental and practical aspects about ozonation processes in water treatment and provides an overview about ozone reaction mechanisms and byproducts formation. The fifth chapter focuses on the reactivity of halide ions, particularly bromide and iodide, with common oxidants and the role they play in determining the speciation of DBPs in treated waters. The chapter also presents strategies to mitigate the formation of DBPs during oxidation processes. Finally, the last chapter tackles the topic of DBPs formation during potable water reuse. It discusses the formation of DBPs of major concern in both memebrane-based and non-membrane-based potable water reuse treatment schemes.Researchers, water treatment specialists, and regulators will find in this book a valuable and compact resource on several key topics regarding the formation, identification, quantification, and mitigation of DBPs. - Identification and quantification of known and unknown DBPs - Formation of DBPs during different disinfection/oxidation processes - DBPs of concern in new technologies and/or new applications of existing technologies in water treatment

This book was released on 2017 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Haloacetic acids (HAAs) and trihalomethanes (THMs) are two groups of commonly found disinfection by-products (DBPs). Iodinated THMs and HAAs were observed after disinfection of water containing high level of iodide and are proved to be more toxic than their corresponding chlorinated and brominated species. In the presented dissertation, a novel rapid and sensitive high performance ion chromatography-tandem mass spectrometry (HPIC-MS/MS) method has been developed for simultaneous analysis of all these HAAs, bromate, bromide, iodide, and iodate, seventeen compounds in total, without any tedious sample preparation. Besides an efficient analytical method for the detection of DBPs, seeking for a green disinfectant with a low formation of DBPs is necessary. Peracetic acid (PAA) has been demonstrated to be a possible green disinfectant that has the potential to reduce the formation of THMs, HAAs and other DBPs. The formation potential of HAAs and THMs, especially the iodinated forms, from PAA disinfection has been investigated and compared with that from FC treatment. Another efficient way to control DBPs is to remove their precursors. When using breakpoint chlorination to disinfect the source water containing high concentration of ammonia, high levels of THMs and HAAs will form. In addition, if N-nitrosamine precursors are present, highly toxic N-nitrosamines may form during water treatment process. In the third part of this dissertation, zeolites and activated carbon were examined for ammonia and N-nitrosamine precursors removal when incorporated into drinking water treatment processes"--Abstract, page iv.

This book was released on 2011 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two groups of disinfection byproducts (DBPs) currently regulated in drinking water are trihalomethanes (THMs) and haloacetic acids (HAAs). The objective of this research was to better understand how the water treatment processes employed at four smaller municipal water treatment utilities affects THM and HAA formation by measuring the removal of organic precursors through each major treatment process and by studying the concentrations formed as part of normal treatment and distribution. Major results of this study include the observation that significant organic DBP precursor removal generally only occurs in a single treatment process; sedimentation/ precipitation and activated carbon adsorption processes early in treatment were identified as most effective for the utilities studied in this research, with removals of 50-95%of incoming organic precursor material observed. The Missouri River utility examined in greater detail is also of interest because of periodic high incorporation of bromide present in source water; these bromine-substituted THMs are of additional concern due to their greater mass and potential human health risks. Conventional treatment was found ineffective at altering bromide incorporation into THMs, only decreasing available organic material. Both seasonal and long-term variations in bromine-substituted THMs were observed, with higher apparent bromide concentrations noted during periods of lower river flow rate. Bromide was also found in THMs at upstream Missouri River water utilities, indicating that many in the region could be affected by these changes over time.

Available in PDF, EPUB and Kindle. Book excerpt: Chlorination is the most commonly employed chemical disinfectant in drinking water treatment nowadays. However, several studies reported that chlorination of organic matter in fresh water resulted in formation of disinfection by-products (DBP). Because of concerns over the health effects of organic by-products of chlorination, the use of alternative disinfectants of chloramines, ozone, and chlorine dioxide as primary or secondary disinfection agents is increasing. However, each of these alternatives has also been shown to form its own set of DBP. Concerns regarding the potential health effects of DBP prompted several industrialized countries to develop a number of regu-lations. The disinfectant/disinfection by-product (D/DBP) regulation in United States of America (USA) has set maximum contaminant levels for trihalomethanes (THM) and haloacetic acids (HAA) of 80 and 60 ug/l, respectively.

Download or read book Comparison of Natural Organic Matter (NOM) Removal Processes on Disinfection Byproduct (DBP) Formation During Drinking Water Treatment written by John Ryan Less and published by . This book was released on 2011 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural aquatic organic matter (NOM) reacts with chlorinated disinfectants used to treat public drinking water supplies resulting in the formation of toxic and carcinogenic disinfection byproducts (DBPs). Therefore, treatment processes that reduce the concentration of NOM prior to drinking water disinfection have been found to reduce the formation of these unwanted DBPs. Conventional enhanced coagulation was compared with a novel anion exchange resins for reducing DBP precursors located in the negatively charged fraction of the NOM matrix. Three anion exchange resins (AERs) were compared (IRA-910, IRA-958, and MIEX) to determine which resin would not only remove NOM but DBP precursors as well. All the AERs were found to be highly proficient at NOM reduction specifically the moieties that absorb UV light at 254 nm and 272 nm over 75 minutes of contact time; however, MIEX removed NOM at a faster rate than the Amberlite resins. Results show that pH had no significant effect on the removal of chromophores and fluorophores (i.e. EEM base pairs A and C) when treated with MIEX or enhanced coagulation. Coagulation was effective at removing 30-45% NOM for Akron and Barberton source waters based on peak intensity excitation-emission pairs taken from the EEM (excitation- emission matrix). Peak intensity in the T region of the EEM for the Barberton source water, which correlates to positively charged soluble microbial, was found to be relatively resilient to each NOM removal process. DBP formation was determined as a function of pH for the different NOM removal processes. MIEX resulted in significant reduction in DBP concentrations for both source waters when compared to DBP formation in the chlorinated raw source waters. MIEX out performed both coagulants reducing the formation of DBPs in both source waters. At an elevated chlorine concentration in the raw samples, as pH increases from 6.5 to 8, chloroform formation increases, TCAA concentrations decrease and dichloroacetic acid (DCAA) is not affected. The two coagulants both reduced DBP formation; however, alum appeared to reduce DBP concentrations more significantly than ACH at pH 8.2.

This book was released on 2013 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a concern that disinfection byproducts (DBPs) produced in wastewater effluent may adversely impact the downstream aquatic system and drinking water resources. It is thus imperative to understand the occurrence, fate, transport, and removal of DBPs and DBP precursors to allow further wastewater reuse practices. This work contributed to this topic with the following efforts: 1) a nation-wide survey of the occurrences of many disinfection byproducts; 2) a comparison of the DBP formation potentials of effluent and natural organic matter, termed as dissolved organic carbon and nitrogen; 3) an evaluation of the effects of natural processes, i.e., hydrolysis, photolysis, biodegradation, volatilization, and adsorption, on reducing DBPs from surface waters; and 4) an assessment of conventional water treatment processes in removing DBP precursors. The results indicated the importance of wastewater effluent as a source of many DBPs, highlighted the role of organic nitrogen in forming nitrogenous DBPs, discovered the specificity of natural mechanisms in mitigating DBPs, and identified the deficiency of conventional treatment processes in respond to potential wastewater impact.
