Odor complaints are on the rise as ongoing residential and commercial developments in our cities bring more and more people within close proximity to wastewater collection systems and treatment plants, and as this development spurs the expansion of collection and treatment facilities to handle ever-increasing capacity needs. This book is a collection of papers presented at the WEFTEC 2000 Odor and Corrosion workshop. By collecting the presentations made by the leading experts in this discipline-including presentations on odor and corrosion control in wastewater systems. The information in this book should be of interest and value to all collection systems.

Intended as a practical reference for professionals involved in managing air emissions from wastewater systems, this work examines practical topics related to odor control and potentially toxic air emissions control. Chapters cover characteristics and measurement of odor and toxic air emissions, relevant regulations and policies, potential emission sources, control strategies, containment and ventilation from treatment facilities, and public communications. A number of chapters deal address gas-phase treatment techniques. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).

Wastewater treatment works have the potential to generate unpleasant odours, which can results in annoyance and consequently have a detrimental effect on a local population. As a result 'odour control and prevention' has become an important consideration both in the management of existing facilities and in the design and gaining of planning consent for new works. Odours in Wastewater Treatment provides readers with a detailed discussion on the basic principles involved in the formation of volatile compounds in wastewater treatment. Accounts are given of recent developments in the sampling and measurement of odours, practical examples in the prediction and dispersion of odorous emissions are offered and an overview of the technologies currently used to contain and treat odorous compounds presented. Contents Introduction Odours associated with wastewater treatment Odour sampling and measurement Assessment and prediction of nuisance odours Odour control and treatment

Odor & Corrosion Control in Sanit.Sewage

A comprehensive guide to the causes and control of odors in wastewater plants, lagoons, and sewer systems, this book explains the chemical and microbiological conditions that lead to foul smells, potential health hazards for workers, and complaints from citizens. After reviewing the chemical compounds most implicated in water- and airborne odors, the authors show how specific bacteria generate these compounds in multiple, often anaerobic, treatment processes and how bacterial activity is tested both in the field and in the lab, which allows plant personnel to take steps to prevent odors before they become a problem. The authors show how variations in plant conditions such as diurnal flow, FOGs, and temperature can lead to unexpected odors, and they offer custom strategies for combatting odors in such situations. Special attention is given to ammonia, methane, and sulfide formation and the latter's effects, such as corrosion and respiratory risks. Evidence-based methods to control odors are described for plants and collection systems of all sizes. Technologies include approaches based on biology, such as bioaugmentation and ones based on chemistry, e.g., sulfide precipitation, as well as instructions for when and where to clean equipment and cover exposed odor sources.

Since the first edition was published over a decade ago, advancements have been made in the design, operation, and maintenance of sewer systems, and new problems have emerged. For example, sewer processes are now integrated in computer models, and simultaneously, odor and corrosion problems caused by hydrogen sulfide and other volatile organic compounds, as well as other potential health issues, have caused environmental concerns to rise. Reflecting the most current developments, Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, offers the reader updated and valuable information on the sewer as a chemical and biological reactor. It focuses on how to predict critical impacts and control adverse effects. It also provides an integrated description of sewer processes in modeling terms. This second edition is full of illustrative examples and figures, includes revisions of chapters from the previous edition, adds three new chapters, and presents extensive study questions. Presents new modeling tools for the design and operation of sewer networks Establishes sewer processes as a key element in preserving water quality Includes greatly expanded coverage of odor formation and prediction Details the WATS sewer process model Highlights the importance of aerobic, anoxic, and anaerobic processes Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, provides a basis for up-to-date understanding and modeling of sewer microbial and chemical processes and demonstrates how this knowledge can be applied for the design, operation, and the maintenance of wastewater collection systems. The authors add chemical and microbial dimensions to the design and management of sewer networks with an overall aim of improved sustainability for the system itself and the surrounding environment.
