Biological Wastewater Treatment  Principles  Modeling and Design

The first edition of this book was published in 2008 and it went on to become IWA Publishing’s bestseller. Clearly there was a need for it because over the twenty years prior to 2008, the knowledge and understanding of wastewater treatment had advanced extensively and moved away from empirically-based approaches to a fundamental first-principles approach based on chemistry, microbiology, physical and bioprocess engineering, mathematics and modelling. However the quantity, complexity and diversity of these new developments was overwhelming for young water professionals, particularly in developing countries without readily available access to advanced-level tertiary education courses in wastewater treatment. For a whole new generation of young scientists and engineers entering the wastewater treatment profession, this book assembled and integrated the postgraduate course material of a dozen or so professors from research groups around the world who have made significant contributions to the advances in wastewater treatment. This material had matured to the degree that it had been codified into mathematical models for simulation with computers. The first edition of the book offered, that upon completion of an in-depth study of its contents, the modern approach of modelling and simulation in wastewater treatment plant design and operation could be embraced with deeper insight, advanced knowledge and greater confidence, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks, or biofilm systems. However, the advances and developments in wastewater treatment have accelerated over the past 12 years since publication of the first edition. While all the chapters of the first edition have been updated to accommodate these advances and developments, some, such as granular sludge, membrane bioreactors, sulphur conversion-based bioprocesses and biofilm reactors which were new in 2008, have matured into new industry approaches and are also now included in this second edition. The target readership of this second edition remains the young water professionals, who will still be active in the field of protecting our precious water resources long after the aging professors who are leading some of these advances have retired. The authors, all still active in the field, are aware that cleaning dirty water has become more complex but that it is even more urgent now than 12 years ago, and offer this second edition to help the young water professionals engage with the scientific and bioprocess engineering principles of wastewater treatment science and technology with deeper insight, advanced knowledge and greater confidence built on stronger competence.

Advanced Biological Treatment Processes

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution problems has been a major contributing factor to the success of environmental en- neering, and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste production, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste.

Die Schleifung

So wie der Begriff "Ikonoklasmus" fur den Bereich der Kunstobjekte genutzt wird, fragt sich, ob der Begriff "Schleifung" fur den zerstorerischen Umgang mit historisch-politischen Baudenkmalern zutreffend ware.

Die Schleifung

Zur Kultur- und Gesellschaftsgeschichte gehort die bewusste Zerstorung, die Uberformung von Strukturen, Bauwerken und Objekten von symbolischer, politischer oder religioser Bedeutung mit dem Ziel der Identitatsstorung. Der Umgang mit den zerstorten Gebauden und Strukturen spiegelt die Absicht, neue Identitaten zu schaffen bzw. an fruhere anzuknupfen. Das Phanomen der Zerstorung symboltrachtiger Bauten und der Umgang mit ihnen sowie der sie umgebenden Strukturen ist in gleicher Weise von Sprach- und Begrifflosigkeit gekennzeichnet. So wie der Begriff "Ikonoklasmus" fur den Bereich der Kunstobjekte genutzt wird, fragt sich, ob der Begriff "Schleifung" fur den zerstorerischen Umgang mit historisch-politischen Baudenkmalern zutreffend ware. Anhand von Beispielen aus Deutschland und Polen hat diese Fragen ein Workshop im Deutschen Historischen Museum untersucht. Polen und Deutschland bieten sich nicht nur wegen der nachbarschaftlichen Nahe an, sondern insbesondere wegen der Vergleichbarkeit von Gemeinsamkeiten und Gegensatzen in der Zerstorung und im Umgang mit dem Zerstorten. Experten aus beiden Landern stellen Beispiele des Abrisses und des Wiederaufbaus historischer Bauten und Ensembles heraus und diskutieren, ob sich aus Ahnlichkeiten der Entwicklungen definitorische Typisierungen beschreiben lassen.
