The release of unpleasant odours during wastewater and sludge treatment and disposal is not new. However, in recent years the level of complaints concerning the release of these offensive odours has increased. This is in part a direct result of the encroachment of housing on lands surrounding existing wastewater and sludge treatment works, together with the raised awareness of the public over its rights related to environmental issues. To avoid the creation of nuisance odours in wastewater and sludge treatment requires an understanding of those processes that are responsible. Odours that are formed within wastewater and sludge will not create an odour nuisance until they are released into the atmosphere. It is therefore important to understand the mechanisms by which odours are formed and then released and dispersed in order to provide effective control systems. The CIWEM-IAWQ odour conference enabled practitioners, regulators and researchers to present findings on a wide range of topics relating to the control and prevention of odours. Twenty-two papers have been selected for these proceedings. They examine the regulation of odour emissions, techniques used to measure and model odour emissions and treatment technologies used to control and prevent odour formation and emission.

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.

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).

A general review of literature published from 1990 to 2000 and unpublished (gray) literature on odors associated with municipal wastewater collection systems and treatment facilities, including biosolids handling. The literature review focused on several areas including odor characterization technology, odor sampling, analysis, measurement technology, and odor mitigation (control) technology.
