Kinetics of Wastewater Treatment contains the proceedings of a post-conference seminar held at the Technical University of Denmark, Copenhagen in 1978. Separating 10 papers presented in the seminar as chapters, this book begins with the conceptual basis of calcium phosphate precipitation in a denitrifying biofilm. The influence of pH and calcium ions upon phosphorus transformations in biological wastewater treatment plants; sewage treatment by activated sludge; orthokinetic flocculation of phosphate precipitates in a multicomponent reactor with non-ideal flow; and kinetics of phosphorus transformations in aerobic and anaerobic environments are then described. This text also looks into the chemical floc formation in wastewater treatment; temperature dependency of microbial reactions; the influence of some environmental factors on floc kinetics; kinetics of biological flocs; and two step precipitation of calcium phosphates.

Interest in ozonation for drinking water and wastewater treatment has soared in recent years due to ozone's potency as a disinfectant, and the increasing need to control disinfection byproducts that arise from the chlorination of water and wastewater. Ozone Reaction Kinetics for Water and Wastewater Systems is a comprehensive reference that

This book presents the basic principles for evaluating water quality and treatment plant performance in a clear, innovative and didactic way, using a combined approach that involves the interpretation of monitoring data associated with (i) the basic processes that take place in water bodies and in water and wastewater treatment plants and (ii) data management and statistical calculations to allow a deep interpretation of the data. This book is problem-oriented and works from practice to theory, covering most of the information you will need, such as (a) obtaining flow data and working with the concept of loading, (b) organizing sampling programmes and measurements, (c) connecting laboratory analysis to data management, (e) using numerical and graphical methods for describing monitoring data (descriptive statistics), (f) understanding and reporting removal efficiencies, (g) recognizing symmetry and asymmetry in monitoring data (normal and log-normal distributions), (h) evaluating compliance with targets and regulatory standards for effluents and water bodies, (i) making comparisons with the monitoring data (tests of hypothesis), (j) understanding the relationship between monitoring variables (correlation and regression analysis), (k) making water and mass balances, (l) understanding the different loading rates applied to treatment units, (m) learning the principles of reaction kinetics and reactor hydraulics and (n) performing calibration and verification of models. The major concepts are illustrated by 92 fully worked-out examples, which are supported by 75 freely-downloadable Excel spreadsheets. Each chapter concludes with a checklist for your report. If you are a student, researcher or practitioner planning to use or already using treatment plant and water quality monitoring data, then this book is for you! 75 Excel spreadsheets are available to download.

Introduction to Wastewater Treatment Processes considers various types of wastewater problems and the selection of proper mode of treatment, as well as the design of the equipment required. This book is divided into eight chapters and begins with a summary of the theory involved in the specific process, such as chemical kinetics and material and energy balances. The next chapter deals with the physical and chemical principles of wastewater treatment processes. These topics are followed by discussions of the important design parameters involved in the process and the determination of such parameters using laboratory-scale or pilot-plant equipment. Other chapters explore the development of a systematic design procedure for the treatment plant. The final chapters look into the mathematical modeling of biological treatment processes. This book will prove useful to practicing engineers and students.

Watermaths presents the mathematics underpinning the design and operation of the individual unit process technologies used for purifying water and wastewater. The book aims to provide the reader with sufficient information to enable them to tackle the most important calculations in this area, without requiring any prior knowledge of the subject and assuming only a very basic grounding in science or engineering. It focuses on the most essential areas of knowledge required, containing tuition in basic numeracy, chemistry, process engineering and fluid physics, as well as cost analysis. The simple and succinct delivery is designed to get the reader up to speed as rapidly as possible: sufficient background information is provided to explain the purpose of the calculations, and ultimately tackle the complete wastewater reclamation plant design problem included in the book. Example calculations are provided within each chapter, each followed by exercises intended to reinforce the learning (and for which solutions are appended). Exercises range in difficulty from simple single calculational-step problems to more complex ones, and the over-arching design problem provides some context to the mathematics. The book can be understood by those relatively new to the water sector, and is intended as a primer rather than a comprehensive handbook. It is nonetheless sufficiently comprehensive to permit design calculations for most water and wastewater treatment unit processes. Core disciplines covered include: • manipulation of equations, including logarithmic and exponential expressions • fluid physics for describing flow through pipes, channels and filters • chemical concentrations and chemical/biochemical reactions • chemical/biochemical reaction kinetics • mass balance for determining fate of materials through unit processes • mass transfer for determining transfer of materials across boundaries within processes • reactor theory for designing biochemical and chemical reaction vessels • cost analysis, including capital and operating expenditure with discounting. New to the third edition: • new chapter on cost analysis • further explanation of the classical unit operations types • illustrations expanded to include unit operation schematics and symbols • new examples and exercises • updated design problem. Watermaths … just add water.

The 2nd edition of Fundamentals of Wastewater Treatment and Design introduces readers to the fundamental concepts of wastewater treatment, followed by engineering design of unit processes for sustainable treatment of municipal wastewater and resource recovery. It has been completely updated with new chapters to reflect current advances in design, resource recovery practices and research. Another highlight is the addition of the last chapter, which provides a culminating design experience of both urban and rural wastewater treatment systems. Filling the need for a textbook focused on wastewater, it covers history, current practices, emerging concerns, future directions and pertinent regulations that have shaped the objectives of this important area of engineering. Basic principles of reaction kinetics, reactor design and environmental microbiology are introduced along with natural purification processes. It also details the design of unit processes for primary, secondary and advanced treatment, as well as solids processing and removal. Recovery of water, energy and nutrients are explained with the help of process concepts and design applications. This textbook is designed for undergraduate and graduate students who have some knowledge of environmental chemistry and fluid mechanics. Professionals in the wastewater industry will also find this a handy reference.
