This book was released on 2004 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was to discuss the potential advantages associated with booster disinfection, the kinetics of chlorine decay and trihalomethane (THM) formation under rechlorination conditions, and the use of network hydraulic and water quality models to locate booster disinfection stations and determine their dose characteristics. The following are highlights from the research: A laboratory procedure was proposed for analyzing chlorine decay under simulated booster conditions. An initial set of experiments evaluated disinfectant decay under booster conditions, and found it to be dependent on both the magnitude and time of the boost dose. THM formation under booster conditions showed no long-term reduction for any set of results, indicating THM formation is not solely dependent on disinfectant concentration. In booster chloramination, boosting with chlorine appeared to be very successful at producing and maintaining a low ammonia concentration by recombining with the ammonia formed from chloramine decay. A second-order model, including a reaction component that represents natural organic matter, was developed to describe chlorine decay and THM formation under booster conditions. A method was developed to determine good locations and schedules for multiple booster doses by a systematic evaluation of alternative designs using network models. By exploring the disinfection decay kinetics under rechlorination, and developing methods for booster chlorination systems design, the project results will assist utilities and consultants in making better use of booster disinfection as a residual maintenance approach.

Available in PDF, EPUB and Kindle. Book excerpt: The report presents a foundation of feedback control algorithms and associated modeling tools. This foundation is necessary for the future development of utility-specific control schemes. The ultimate vision adopted in the report is one of a multiple-input, multiple-output (MIMO) feedback control system, where booster chlorination stations are distributed at key points in the system and are fed information from distributed chlorine sensors located in critical areas. The report also presents the elements of a comprehensive design method for distributed chlorine controller design.Originally published by AwwaRF for its subscribers in 2003 This publication can be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

This book was released on 2011-01-12 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brand new manual was written because of the increased use of chloramine as a residual disinfectant in drinking water distribution systems and the ubiquitous presence of nitrifying bacteria in the environment. Chapters cover background information on the occurrence and microbiology of nitrification in various water environments and provide current practical approaches to nitrification prevention and response. This manual provides a compendium of the current state-of-the-art knowledge, however with quickly developing new advances in nitrification, more writings will be forthcoming. Each chapter can be read independently.

This book was released on 2008 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual chlorines are provided in water distribution systems to maintain the inactivation of pathogens intruded into network. The effectiveness of chlorine residuals on pathogen removal can be determined using system vulnerability assessment. The effectiveness of chlorination was determined separately and it was determined as higher than that of the distribution and dilution for two case networks studied. CT (Chlorine Residual Concentration x Contact Time) value which is used as an important criterion to assess the inactivation of pathogens, is complicated to be determined for distribution networks due to varying residence times and chlorine concentrations. The relation of CT value with the removal ratio of pathogens was used to estimate CT value for distribution networks. The results of case studies indicate that CT value determined for a distribution network does not only depend on concentration and contact time of chlorine residuals but also temperature, pH and intrusion location and duration.

This book was released on 2007-03-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining chlorine and chloramine residual is a key factor that determines potability of distributed water. Decay of these disinfectants is affected by various water quality and infrastructure related factors. Understanding the decay of residuals in the distribution system is critical with respect to safe delivery of drinking water and in developing water quality models that can be used by utilities for the operation of potable water delivery systems. In order to comply with microbial and disinfection byproduct (M/DBP) regulations, water suppliers are continually investing in treatment processes for achieving greater levels of inactivation and DBP precursor removal. As a result of these changes in water quality, maintaining a disinfectant residual in the distribution system can be challenging Bench-scale testing has been used to determine the effect of advanced treatment (enhanced coagulation, granular activated carbon adsorption, ozonation, biofiltration, and ultraviolet irradiation) on chlorine and chloramine decay. Additional studies examine the effects of disinfectant dose, temperature, pH, blending, and rechlorination. The effects of water quality on pipe-wall demand were evaluated using the distribution system simulator at the U.S. Environmental Protection Agency's Test and Evaluation Center. Several models are developed regarding disinfectant decay, making it easier to predict chlorine demand after changes in treatment. The multi-species water quality analysis and network path analysis extensions to EPANET will make the modeling package more robust and will allow utilities to predict chlorine residual at any point in their distribution system with greater confidence.

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....

Book excerpt: New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.
