Book Description
FROM THE PREFACE Dynamic modeling, computer simulation, and modern control systems are valuable tools for use in both the design and operation of dynamic systems. From the "tools" point of view, this book is designed to show practicing engineers how to develop models capable of describing dynamic behavior and how to "solve" these models using computer simulation. The basic principles of process control are also presented so that the effects of different control systems on dynamic behavior can be established by computer simulation.

Book Description
Environmental quality is becoming an increasing concern in our society. In that context, waste and wastewater treatment, and more specifically biological wastewater treatment processes play an important role. In this book, we concentrate on the mathematical modelling of these processes. The main purpose is to provide the increasing number of professionals who are using models to design, optimise and control wastewater treatment processes with the necessary background for their activities of model building, selection and calibration. The book deals specifically with dynamic models because they allow us to describe the behaviour of treatment plants under the highly dynamic conditions that we want them to operate (e.g. Sequencing Batch Reactors) or we have to operate them (e.g. storm conditions, spills). Further extension is provided to new reactor systems for which partial differential equation descriptions are necessary to account for their distributed parameter nature (e.g. settlers, fixed bed reactors). The model building exercise is introduced as a step-wise activity that, in this book, starts from mass balancing principles. In many cases, different hypotheses and their corresponding models can be proposed for a particular process. It is therefore essential to be able to select from these candidate models in an objective manner. To this end, structure characterisation methods are introduced. Important sections of the book deal with the collection of high quality data using optimal experimental design, parameter estimation techniques for calibration and the on-line use of models in state and parameter estimators. Contents Dynamical Modelling Dynamical Mass Balance Model Building and Analysis Structure Characterisation (SC) Structural Identifiability Practical Identifiability and Optimal Experiment Design for Parameter Estimation (OED/PE) Estimation of Model Parameters Recursive State and Parameter Estimation Glossary Nomenclature

Book Description
FROM THE PREFACE In this time of dwindling budgets, increasing service needs, and increasing regulatory requirements, wastewater treatment professionals are continually called upon to upgrade their wastewater treatment plants. To do so efficiently and effectively, one must develop a clear approach to use in upgrading a plant and have the proper tools available to implement that approach. This book is meant to assist readers in developing and implementing their upgrading projects. First, Chapter 1 details the upgrading approach. The tools to be used are presented in Chapters 2 through 6. Finally, in Chapter 7, six case histories are presented to illustrate the plant upgrading techniques presented in the previous chapters. Through this book, the authors hope to assist readers in meeting their upgrade requirements, while making the most efficient use of the resources at hand.

Book Description
Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natural waste treatment, this text provides a thorough explanation on how soil and plants can successfully sustain microbial populations in the treatment of wastewater. Determining that natural systems cost less to construct and operate, and require less energy than mechanical treatment alternatives, this book also explains how these processes produce lower amounts of residual solids, and use little or no chemicals. What’s New in the Second Edition: This revised edition includes current design and regulatory and operational developments in the natural wastewater treatment field. It provides detailed examples and analyses along with significant operational data in each chapter. It also considers how processes provide passive treatment with a minimum of mechanical elements, and describes new approaches to partially mixed ponds, including dual-powered aeration ponds. Introduces the planning procedures and treatment mechanisms responsible for treatment in ponds, wetlands, land application, and soil absorption systems Provides new case studies of constructed wetlands and water reuse systems Presents design criteria and methods of pond treatment and pond effluent upgrading Describes constructed wetlands design procedures, process applications, treatment performance data, and land treatment concepts and design equations Includes information on constituents of emerging concern (CEC) and their fate in natural systems The text discusses wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. It describes residuals and biosolids management, including nitrogen removal pretreatment methods, and uses U.S. customary and metric units in all chapters. It presents case studies of new applications of natural systems and includes worked examples of design equations for ponds and land treatment. It also provides a biosolids regulatory update from a top EPA scientist, and algae reduction technologies for ponds and wetlands. Designed for practicing wastewater engineers and scientists involved in the planning, design, and operation of ponds, wetlands, land treatment, biosolids, and onsite soil-based treatment systems, the book integrates many natural treatment systems into one single source.

Book Description
by Professor Poul Harremoes Environmental engineering has been a discipline dominated by empirical approaches to engineering. Historically speaking, the development of urban drainage structures was very successful on the basis of pure empiricism. Just think of the impressive structures built by the Romans long before the discipline of hydraulics came into being. The fact is that the Romans did not know much about the theories of hydraulics, which were discovered as late as the mid-1800s. However, with the Renaissance came a new era. Astronomy (Galileos) and basic physics (Newton) started the scientific revolution and in the mid-1800s Navier and Stokes developed the application of Newtons laws to hydrodynamics, and later, St. Venant the first basic physics description of the motion of water in open channels. The combination of basic physical understanding of the phenomena involved in the flow of water in pipes and the experience gained by "trial and error", the engineering approach to urban drainage improved the design and performance of the engineering drainage infrastructure. However, due to the mathematical complications of the basic equations, solutions were available only to quite simple cases of practical significance until the introduction of new principles of calculation made possible by computers and their ability to crunch numbers. Now even intricate hydraulic phenomena can be simulated with a reasonable degree of confidence that the simulations are in agreement with performance in practice, if the models are adequately calibrated with sample performance data.
