Download or read book DBP Formation Control by Modified Activated Carbons written by T. Karanfil and published by IWA Publishing. This book was released on 2008-02-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Powdered or granular activated carbon adsorption has been widely used in drinking water treatment plants primarily for taste, odor, and synthetic organic contaminant (SOC) removal. However, carbon adsorption has not been widely used for controlling DOM due to the low equilibrium capacities and slow adsorption kinetics. The main reason for these drawbacks is that the majority of commercial activated carbons have been developed primarily to remove small molecular weight hydrophobic SOCs from water. As a result, many commercial carbons do not provide feasible engineering solutions for removing large molecular weight and heterogeneous mixtures of DBP precursors. This research was undertaken to develop a fundamental understanding of tailoring activated carbons for DBP control. The main objectives of this project were to (1) conduct a systematic investigation for developing a fundamental understanding of how activated carbons should be tailored for enhanced removal of dissolved organic matter (DOM) from natural waters; and (2) investigate the effectiveness of some carbon tailoring approaches for disinfection by-products (DBP) formation control at typical drinking water treatment conditions. This project showed that the removal of DBP precursor by GAC adsorption can be significantly improved. GAC adsorption, using modified GACs, can provide another alternative to some water utilities for meeting the Stage 2 requirements of the Disinfectant/Disinfection By-Products Rule.

Download or read book Natural Organic Matter and Disinfection By products Characterization and Control in Drinking Water written by Sylvia E. Barrett and published by . This book was released on 2000 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many by-products of water disinfection that are still not fully understood and can be potentially harmful. In this volume all the current research in this area is discussed, along with an examination of the role of NOM (natural organic matter) and its relationship to DBP (disinfection by-product) formation and control in drinking water. Understanding the relationship of NOM to DBP may well lead to new techniques for analyzing and treating water and enable reasonable choices to be made for source-water protection, treatment plant process optimization, and distribution system operation to control DBP's. This volume emphasizes the characterization and reactivity of polar natural organic matter. It examines analytical methods which better characterize NOM and determines some of the polar and nonvolatile DBP forms. It presents innovative new methods, sich as capillary electrophoresis for haloacetic aceids and LC/MS for the identification of polar dinking water DBPs.

Available in PDF, EPUB and Kindle. Book excerpt: "Many books have been written about granular activated carbon. Some focus on the theory of performance and removal mechanisms while others focus on design features. This book focuses on solutions. It describes the challenges facing water providers to provide safe water that is acceptable to their customers, utility experiences using activated carbon, activated carbon applications, and design and procurement approaches. The appendices include detailed case studies and a life-cycle assessment demonstrating favorable sustainability considerations for activated carbon when compared to other treatment technologies. Never before has all of this information been together in one location. The what, why, and how of activated carbon are connected in this book and demonstrate why this treatment technology has maintained its status as an integral treatment technology in the quest for pure water over millennia"--

Available in PDF, EPUB and Kindle. Book excerpt: The Drinking Water Act Amendments of 1996 instituted wide-ranging regulatory changes to the seminal Safe Drinking Water Act (SDWA)-such as providing funding to communities facing health risks, focusing regulatory efforts on contaminants posing such health risks, and adding flexibility to the regulatory process- and the amendments continue to shape regulations and regulatory policy to this day. Editor Frederick Pontius's Drinking Water Regulation and Health provides a comprehensive, up-to-date resource on the current regulatory landscape. Drinking Water Regulation and Health serves as a guide for water utilities, regulators, and consultants, forecasting future trends and explaining the latest developments in regulations.

Expanded from beginning to end, this second edition provides a no-holds-barred look at current management issues and includes the latest security information for protecting public assets. It presents in-depth coverage of management aspects and security needs and a new chapter covering the basics of blueprint reading. The chapter on water and wastewater mathematics has tripled in size and now contains an additional 200 problems and 350 math system operational problems with solutions. The manual examines numerous real-world operating scenarios, such as the intake of raw sewage and the treatment of water via residual management, and each scenario includes a comprehensive problem-solving practice set. The text follows a non-traditional paradigm based on real-world experience and proven parameters. Clearly written and user friendly, this revision of a bestseller builds on the remarkable success of the first edition. This book is a thorough compilation of water science, treatment information, process control procedures, problem-solving techniques, safety and health information, and administrative and technological trends.
