Prepared by the Urban Drainage Standards Committee of the Standards Development Council of the Environmental and Water Resources Institute of ASCE This single-volume set of three Standards establishes guidelines for design, installation, and operation and maintenance of urban subsurface drainage systems. ANSI/ASCE/EWRI 12-13 provides guidelines for the design of these systems and covers site analysis, system configuration, drain envelopes, hydraulics and hydrology, structural considerations, and materials. ANSI/ASCE/EWRI 13-13 focuses on installation and examines site investigation, installation procedures, and inspection. ANSI/ASCE/EWRI 14-13 provides guidelines for operation and maintenance (O&M) of urban subsurface drainage, including O&M plans, safety, water quality, inspection, maintenance, and rehabilitation. This new edition contains major state-of-the-art updates to Standard 12 regarding the hydraulics of different types of drains, including drain pipes, aggregate drains, geotextile drains, and geonets and geocomposite drains. Throughout these Standards, references have been added and updated. Together, the three Standards offer comprehensive guidance for the collection and conveyance of subsurface drainage waters in industrial, commercial, residential, and recreational areas, as well as for applications such as airports, roads, and other transportation systems. Engineers working with subsurface drainage systems, along with the owners of such systems, will find these updated standards to be a valuable resource.

The generation of wastes as a result of human activities has been continuously speeding up since the beginning of the industrial revolution. Hence, both optimized waste water treatment technologies and modern tools to assess the effects of pollution sources are necessary to prevent the contamination of aquatic ecosystems The book offers an interdisciplinary collection of topics concerning waste water treatment technologies, water quality monitoring and evaluation of waste water impact on natural environments. We hope that this publication will be helpful for graduate students, environmental professionals and researchers of various disciplines related to waste water.

This book deals with the modeling, analysis and simulation of problems arising in the life sciences, and especially in biological processes. The models and findings presented result from intensive discussions with microbiologists, doctors and medical staff, physicists, chemists and industrial engineers and are based on experimental data. They lead to a new class of degenerate density-dependent nonlinear reaction-diffusion convective equations that simultaneously comprise two kinds of degeneracy: porous-medium and fast-diffusion type degeneracy. To date, this class is still not clearly understood in the mathematical literature and thus especially interesting. The author both derives realistic life science models and their above-mentioned governing equations of the degenerate types and systematically studies these classes of equations. In each concrete case well-posedness, the dependence of solutions on boundary conditions reflecting some properties of the environment, and the large-time behavior of solutions are investigated and in some instances also studied numerically.

Aerobic granular sludge technology will play an important role as an innovative technology alternative to the present activated sludge process in industrial and municipal wastewater treatment in the near future. Intended to fill the gaps in the studies of aerobic granular sludge, this thesis comprehensively investigates the formation, characterization and mathematical modeling of aerobic granular sludge, through integrating the process engineering tools and advanced molecular microbiology. The research results of this thesis contributed significantly to the advance of understanding and optimization of the bacterial granulation processes, the next generation of technology for cost-effective biological wastewater treatment. Dr. Bing-Jie Ni works at Advanced Water Management Centre (AWMC) of The University of Queensland, Australia.

Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenance provides the information necessary for developing and operating an effective maintenance program for stormwater treatment. The book offers instructions on how to measure the level of performance of stormwater treatment practices directly and bases proposed maintenance schedules on actual performance and historical maintenance efforts and costs. The inspection methods, which are proven in the field and have been implemented successfully, are necessary as regulatory agencies are demanding evaluations of the performance of stormwater treatment practices. The authors have developed a three-tiered approach that offers readers a standard protocol for how to determine the effectiveness of stormwater treatment practices currently in place. This book also: Provides a standard protocol for how to determine the effectiveness of stormwater treatment practices Assists readers with identifying which assessment techniques to use for stormwater treatment while also providing instructions on implementation methods Contains a substantial number of examples and case studies to illustrate the use of the methods discussed in the book Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenance is an ideal reference and handbook for stormwater professionals. .
