New Edition now available - click hereIt is well recognized everywhere that management of sludge derived from wastewater treatment is one of the most critical environmental issues, due to the very fast increase in sludge production as a result of sewerage extension, new installations and upgrading of existing facilities. Within this general picture, sludge is produced under different technical, economic and social contexts, thus requiring different approaches. This report is intended to give an overview of the sludge field in different parts of the world by summarising: current wastewater and sludge treatment provision; current and anticipated legislation; current research horizons; anticipated evolution of management approaches; and prospects for use of innovative and / or simple technologies. The report has been prepared for the Water21 Market Briefing Series in collaboration with the International Water Association's Specialist Group on Sludge Management. It is based on contributions from: Western Europe (Johannes Mueller); Eastern Europe (Pavel Jenicek); North America (Steve Dentel); Latin America and the Caribbean (Jose Barrios); East Asia (Nagaharu Okuno); South Asia and China (Duu-Jong Lee); Africa (Heidi Snyman); and Australasia (David Dixon and Terry Anderson). There is also an introduction and overview section (Ludovico Spinosa).

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.
