Aerobic Wastewater Treatment Processes: History and Development discusses the widely differing influences on the development of aerobic treatment such as water supply, toxic trade effluents, microscopy and population growth in urban areas. It covers the historical development of sewage treatment and the emergence of aerobic biological treatment from the early nineteenth century to the present day. The importance of water supply and the influence this had on the water-carriage system is examined, as is the consequent discharge of sewage into rivers. The factors which govern process selection and process development are discussed. There is a continued impetus to reduce land area, capital costs, running costs, and to optimise performance and process control. The discovery of the activated sludge process is detailed including the development, in the early 1900s, of many forms of this process. Industrial wastes were discharged to biological treatment systems and the impact of such pollutants is reviewed. The work of Royal Commissions, River Boards and the National Rivers Authority is summarised, and the advances in chemical analysis and “on-line” measurement of chemical quality characteristics. Later developments such as reed beds and the use of hybrid treatment systems are covered. Examples are included such as the “fixed film” activated sludge process which has found application for small communities in package form, and also for large-scale municipal treatment plants. Aerobic Wastewater Treatment Processes: History and Development is valuable reading for students of the following courses on CIWEM Dip examination, WITA and B Tech and Environmental Science and Civil Engineering.

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.

Pollution and its effects on the environment have emerged as critical areas of research within the past 30 years. The Handbook of Environmental Engineering is a collection of methodologies that study the effects of pollution and waste in their three basic forms: gas, solid, and liquid. In Volume 8, Biological Treatment Processes, tried-and-true solutions comprise a “methodology of pollution control”. The distinguished panel of authors contributes detailed chapters, which include topics ranging from treatment by land application, activated sludge processes, and submerged aeration to trickling filters, lagoons, rotating biological contactors, sequencing batch reactors, digestions, and composting. Volume 8 and its sister book - Volume 9: Advanced Biological Treatment Processes – are designed as both basic biological waste treatment textbooks and reference books for advanced undergraduate and graduate students – as well as for designers of waste treatment systems, scientists, and researchers. An indispensable addition to the Humana Press series, Volume 8: Biological Treatment Processes provides an illuminating look at water pollution control and the fascinating evolution of bio-environmental engineering.

Each section of the text gives step-by-step learning in a particular subject, that includes an approximation of how long you will need to spend on that section and provides key points that highlight the principles of the different sections. Each unit includes exercises to help understand the material in the text, self-assessment questions to test your understanding and text references.

Many industrial processes use water as a solvent and therefore produce wastewater containing chemicals from that process. The amounts of these chemicals and the types will vary hugely depending on the industry and the processes running and may include things that are hazardous to health or the environment. This makes the treatment of industrial wastewater both extremely important and highly complex. One route for industrial wastewater treatment is the use of bioreactors. Biological Treatment of Industrial Wastewater presents a comprehensive overview of the latest advances and trends in the use of bioreactors for treating industrial wastewater. Several different types of bioreactor and their applications are discussed, alongside trends and considerations important in designing bioreactors. Bringing together a wealth of different approaches and voices this book will be a useful resource for anyone working in water treatment or looking at how industrial processes can be made more environmentally friendly.
