Download or read book Formation and Decay of Disinfection By products in the Distribution System written by and published by American Water Works Association. This book was released on 2006 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was to understand the formation and decay of selected DBPs in full-scale distribution systems focusing on the four THMs and the nine HAAs, as well as individual THM and HAA species. Because of its critical nature, NDMA was also included. The project objectives were: evaluate the critical factors that affect THM and HAA behavior in distribution systems; determine the fate and behavior of NDMA in distribution systems; evaluate the effect of pipe material and diameter on the fate of DBPs in distribution systems; examine the effect of storage reservoirs / tanks and booster chlorination stations on THM, HAA and NDMA concentrations; evaluate the changes in DBP concentrations and speciation when a system seasonally switches from chloramines to free chlorine to limit potential nitrification episodes....

Download or read book Control of Disinfection By products in Drinking Water Systems written by Anastasia Nikolau and published by Nova Publishers. This book was released on 2007 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of disinfection by-products (DBPs) in drinking water has been an issue of major concern during several decades. The formation of many DBPs species during water disinfection has been documented, while new by-products are still being detected, as the analytical instrumentation available becomes more accurate and sensitive. Most of the DBPs have been proven to have toxic effects on living organisms; therefore they pose risks to human health during drinking water consumption. The factors affecting their formation have been extensively investigated, their transport and fate have been studied, modelling efforts for several of them have been performed, in order to understand better their behaviour and therefore try to minimise their occurrence in waters. Techniques for their removal from water have also been applied, and a variety of disinfection methods or combinations of disinfecting agents have been investigated with the aim to produce safe drinking water containing the minimum possible concentrations of DBPs. This book deals with the advances in control of DBPs in drinking water systems. Further than an providing an overview of existing disinfection techniques and by-products, up-to-date information on the parameters affecting the procedures of DBPs formation, analytical methods for their determination, toxicity, regulation, it pays special emphasis on the advanced treatment methods applied recently for DBPs control and presents recent promising findings as well as case studies in this field, as the relevant research is proceeding, producing more knowledge and practical solutions in regard to the disinfected drinking water quality.

Download or read book Applications of Advanced Oxidation Processes AOPs in Drinking Water Treatment written by Antonio Gil and published by Springer. This book was released on 2018-07-03 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the drinking water treatments in which AOPs display a high application potential. Firstly it reveals the typical supply sources and limitations of conventional technologies and critically reviews natural organic matter characterization and removal techniques, focusing mainly on AOP treatments. It then explores using AOPs for simultaneous inactivation/disinfection of several types of microorganisms, including highly resistant Cryptosporidium protozoa. Lastly, it discusses relevant miscellaneous topics, like the most promising AOP solid catalysts, the regime change of Fenton-like processes toward continuous reactors, the application of chemometrics for process optimization, the impact on disinfection byproducts and the tracing of toxicity during AOP treatments. This work is a useful reference for researchers and students involved in water technologies, including analytical and environmental chemistry, chemical and environmental engineering, toxicology, biotechnology, and related fields. It is intended to encourage industrial and public-health scientists and decision-makers to accelerate the application of AOPs as technological alternatives for the improvement of drinking water treatment plants.

Download or read book Complying with Trihalomethane Reduction Requirements in Water Treatment Facilities written by Philip C. Singer and published by Noyes Publications. This book was released on 1989-01-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight case studies from around the United States involving the reduction of trihalomethane in water treatment facilities. Includes information on finished water quality, treatment plant performance, and costs for each example. "From the Introduction: " In order to comply with the maximum contaminant level (MCL) for total trihalomethanes (TTHM), many utilities have modified their pre-oxidation and disinfection practices by switching to alternative oxidants and disinfectants in place of free chlorine. Examples of such modifications include the use of chlorine dioxide (C102), ozone (O3) or potassium permanganate (KMnO4) as pre-oxidants and disinfectants with free chlorine used as the final disinfectant, and the use of free chlorine as a pre-oxidant and disinfectant with combined chlorine (e.g., monochloramine (NH2Cl)) used as the final disinfectant. In fact, the final rule establishing an MCL for TTHM in November 1979 (EPA, 1979) was followed in March 1982 by a guidance document for utilities in which the EPA proposed treatment technologies which could be used to control trihalomethane (THM) levels. Three of the five "generally available" treatment methods included the use of chloramines or chlorine dioxide as alternative or supplemental disinfectants or oxidants, and the substitution of chloramines, chlorine dioxide, and potassium permanganate as pre-oxidants in place of chlorine. The proposal also included, as an additional treatment method which should be considered but which was not identified as "generally available," the use of ozone as an alternate or supplemental disinfectant or oxidant. These proposals were subsequently adopted by EPA in February 1983 (EPA, 1983). At the time

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides an assessment of the carcinogenicity of 18 chemicals present in industrial and consumer products or food (natural constituents, contaminants, or flavorings) or occurring as water-chlorination by-products. The compounds evaluated include the widely used plasticizer di(2-ethylhexyl) phthalate and the food contaminant 4-methylimidazole. In view of the limited agent-specific information available from epidemiological studies, the IARC Monographs Working Group relied mainly on carcinogenicity bioassays, and mechanistic and other relevant data to evaluate the carcinogenic hazards to humans exposed to these agents.
