This project will deal with a number of aspects of WAS-only-reduction technologies for both industrial and municipal wastewater treatment applications. The objectives of this project include the following: 1. Developing an evaluation methodology that can be used to independently assess the effectiveness of WAS-reduction technologies 2. Demonstrating the previously listed methodology with at least one WAS-reduction technology This study includes not only the primary goals of establishing the degree of WAS reduction and corresponding capital and operation and maintenance (O&M) costs, but also such details as impacts on dewaterability (e.g., changes in polymer requirements, and maximum solids content achievable), changes in volatile solids reduction and corresponding biogas production in anaerobic digestion, possible odor issues in terms of in-plant processing requirements or ultimate product quality for disposal that result from these processes, and the change in characteristics of the recycle streams back to the main process (such as increased nutrient return, increased total suspended solids [TSS] return, phosphorus removal, etc.). In addition to the more technical parameters, the adopted approach also considers evaluations of operability, reliability, and maintainability on each of the leading processes. Some of these effects were determined by laboratory testing and plant data evaluation. Others were investigated through comprehensive modeling using standard industry models such as ASM 2d for liquid-stream biological treatment and the ADM1 model for anaerobic digestion. A key objective of this work is an impartial validation of these technologies and the development of a methodology for assessment of additional technologies that currently do not exist, but could be developed in the future. This requires not only real world operating data, but also a degree of understanding of the fundamental mechanism behind the process. As such, a critical part of this project involves the discussion of the potential underlying mechanisms for each of the validated technologies.

From the book's introduction: This is not an introductory text about activated sludge. In this book, we discuss the observation, testing, and calculation procedures that provide data about the status of the activated sludge process. In addition, we discuss in depth how to apply this data to the business of controlling your activated sludge treatment process. Basic activated sludge concepts are addressed in this book in the context of process evaluation and control. We focus our efforts on discussing a basic, practical system of control for the process. The procedures discussed in this manual are equally applicable to all variations. An operator must have information about settleability, dissolved oxygen concentration, solids concentration, effluent quality, and clarifier sludge levels for consistent, efficient process performance of every type of activated sludge process. These procedures are covered in detail. The procedures discussed are based on work done by E. B. Mallory in the 1930's and 40's and further developed by Alfred W. West while he was head of the Operational Technology Branch of the Environmental Protection Agency in the 1960's and 70's. The system, with some modifications by this author, is frequently called the "West Method" or "Sludge Quality Method" of activated sludge process control because operational controls adjustments are based on the sludge quality existing in your facility rather than on arbitrary values.

Activated Sludge - 100 Years and Counting covers the current status of all aspects of the activated sludge process and looks forward to its further development in the future. It celebrates 100 years of the Activated Sludge process, from the time that the early developers presented the seminal works that led to its eventual worldwide adoption. The book assembles contributions from renowned world leaders in activated sludge research, development, technology and application. The objective of the book is to summarise the knowledge of all aspects of the activated sludge process and to present and discuss anticipated future developments. The book comprises invited papers that were delivered at the conference "Activated Sludge...100 Years and Counting!", held in Essen, Germany, June 12th to 14th, 2014. Activated Sludge - 100 Years and Counting is of interest to researchers, engineers, designers, operations specialists, and governmental agencies from a wide range of disciplines associated with all aspects of the activated sludge process. Authors: David Jenkins, University of California at Berkeley, USA, Jiri Wanner, Institute of Chemical Technology, Prague, Czech Republic.

Describes dewatering processes for municipal wastewater sludge. Up to date information is provided which a design engineer, or others involved in the decision making process for sludge treatment, can use to select appropriate dewatering processes for particular applications. The object is to reduce sludge volume, producing a sludge which behaves as a solid, not a liquid, and subsequently reducing the cost of treatment and disposal.

In the past, industrial wastewater treatment primarily focused on the removal of BOD and suspended solids. In recent years, however, the focus has changed to aquatic toxicity, priority pollutants, and volatile organics. This required changes in how we design and operate biological treatment plants. Many existing plants must be retrofitted. New approaches to meet new requirements are discussed in detail. The authors, with a combined experience of sixty years, have presented case studies for a wide variety of industrial wastewaters including pulp and paper, food processing, chemical and pharmaceuticals, and textile wastewaters. Data interpretation and process design are developed through the use of seventeen examples. Procedures for the laboratory and pilot plant generation of process design data are presented. Emphasis is placed on meeting the many new regulations governing industrial wastewater discharges.
