Impact/Purpose:
to inform the public
Description:
One characteristic by which sanitary sewage is known to the public is its potential for creating odor nuisances. Sometimes it is the odors escaping from sewer manholes that cause complaints; more commonly, the source is a wastewater treatment plant. Yet there are wastewater treatment plants that are free from this stigma. Techniques to prevent odor nuisances are available, and if there is a commitment to construct odor-free sewage works, it can be done. The main cause of odors in sewerage systems is hydrogen sulfide, a gas detectable in very low concentration. Hydrogen sulfide is also noted for its toxicity and for its ability to cause corrosion of various materials used in sewer construction. Much research has been done on various aspects of the sulfide problem in the last three decades. Beside extensive studies in the United States, important contributions have been made by engineers in Australia under the leadership of a Standing Committee of the Principal sewerage authorities. In South Africa, research has been done on the corrodibility of concrete under conditions that may develop in sewers. The first attempt at a comprehensive treatise on the sulfide problem was published as a joint effort of the engineers in Australia. Despite the completion of that work, there is more that can be added on the basis of results of recent research in the United States. A comprehensive design manual is necessary to bring together the information now available into a form convenient for use by engineers who are designing sewers or who are faced with the need to apply sulfide control procedures in existing sewers. This Manual is intended to satisfy that need. It is based principally upon sources of information in the cited references. Some of the data, however, including that developed by research and development projects of the U.S. EPA, have not yet been published elsewhere, and some of the deductions were developed from published and unpublished data in the course of the preparation of the Manual.
