Description

From the Preface: Through the 1990s and the early 2000s, the use of mathematical modeling of wastewater treatment processes moved from being the subject of academia in universities and research organizations to mainstream use by process engineers for design in many engineering firms in North America and throughout the world. Significant credit for this transition can be attributed to the phenomenal increase in the processing power and general use of personal computers throughout the industry. Hand in hand with increased processing power, several companies have developed simulation software that is straightforward to use and capable of modeling many of the complexities of a wastewater treatment facility. These simulators can be used to develop mass-balance models of the plant, linking several unit processes together, and modeling their interactions. In addition, many of these simulators can be used to carry out dynamic simulations to investigate diurnal and other transient behavior of a wastewater treatment facility, such as the effect of wet weather. With an increased use of process models through user-friendly simulators, there has been widespread acknowledgment in the industry that good training and expert guidance is needed to ensure that these models are developed, used, and documented correctly. This manual provides a broad range of information to allow process engineers to understand general modeling concepts, terminology unique to computer modeling, and practical guidance and ideas on how to use process models for design of small, medium, and large wastewater treatment plants. Formed in 1928, the Water Environment Federation(r) (WEF(r)) is a not-for-profit technical and educational organization with individual members and affiliated Member Associations representing water quality professionals around the world. WEF and its global network of Member Associations (MAs) help provide water quality professionals with the latest in water quality education, training, and business opportunities. WEF's diverse membership includes scientists, engineers, regulators, academics, plant managers and operators, and other professionals. Visit www.wef.org for more informat
