Recently, research efforts aiming to improve energy efficiency of wastewater treatment processes for large centralized wastewater treatment plants (WWTPs) have been increasing. Global warming impacts, energy sustainability, and biosolids generation are among several key drivers towards the establishment of energy-efficient WWTPs. WWTPs have been recognized as major contributors of greenhouse gas emissions as these are significant energy consumers in the industrialized world. The quantity of biosolids or excess waste activated sludge produced by WWTP will increase in the future due to population growth and this pose environmental concerns and solid waste disposal issues. Due to limited capacity of landfill sites, more stringent environmental legislation, and air pollution from incineration sites, there is a need to rethink the conventional way of dealing with wastewater and the sludge production that comes with it. This book provides an overview of advanced biological, physical and chemical treatment with the aim of reducing the volume of sewage sludge.

This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

This book gives a most detailed presentation of the theories behind modern wastewater treatment processes. It presents an up-to-date description of wastewater characteristics and the theories of biological processes and their modelling. The quantitative information density is unique due to the numerous tables, figures and examples.The book is primarily intended for graduate and PhD students, but owing to the abundant quantitative information it is also valuable for consulting engineers and other professionals who deal with wastewater treatment. The book has an extensive Table of Contents and list of symbols, which makes it useful as a handbook.

Das explosionsartige Anwachsen des chemischen Wissens hat in den letzten Jahrzehnten im Bereich der organischen Chemie zu einer schier unübersehbaren Anzahl neuer und neuartiger Verbindungen und Verbindungsklassen geführt, deren rationelle Benennung immer größere Schwierigkeiten bereitete. Ursprünglich war ja die Namensgebung eines neuen Stoffes weitgehend, wenn nicht völlig in das Belieben des Entdeckers gestellt, der den Namen häufig von einer direkten sinnlichen Wahrnehmung ableitete oder sich gar ganz von der Intuition leiten ließ. Da die mehr oder weniger willkürlich gebildeten "Trivialnamen" meist gar nichts über die Strukturen der Verbindungen aussagten, konnten sie auch in keinen sinnvollen Zusammenhang zueinander ge bracht werden. Mit dem zunehmenden Verständnis der strukturellen Beziehungen der Organischen Chemie wuchs aber die Tendenz, eine allgemeinverbindliche und systema tische Nomenklatur zu entwickeln, die es erlauben sollte, wesentliche konstitutionelle Aussagen über ein Molekül be reits aus dessen Namen abzuleiten. Andererseits wollte man einen großen Teil der althergebrachten Trivial- und Semi trivialnamen nicht so ohne weiteres aufgeben. Dennoch ist es den damit befaßten Instanzen der "International Union of Pure and Applied Chemistry", der IUPAC, gelungen, ein einheitliches und ausbaufähiges Nomen klatursystem zu entwickeln, das mittlerweile allgemein und international anerkannt ist. Die Originalfassung der IUPAC Nomenklaturregeln der Organischen Chemie ist ein unver zichtbares Hilfsmittel für den Spezialisten. Als Einführung in die Materie ist jedoch eine knappere und präzisere "Ge brauchsanweisung" eher am Platze, die an Hand zahlreicher, sorgfältig ausgewählter bzw. konstruierter Beispiele die Geltungsbereiche der einzelnen Regeln möglichst voll ständig überstreicht.
