The FISH Handbook for Biological Wastewater Treatment provides all the required information for the user to be able to identify and quantify important microorganisms in activated sludge and biofilms by using fluorescence in situ hybridization (FISH) and epifluorescence microscopy. It has for some years been clear that most microorganisms in biological wastewater systems cannot be reliably identified and quantified by conventional microscopy or by traditional culture-dependent methods such as plate counts. Therefore, molecular biological methods are vital and must be introduced instead of, or in addition to, conventional methods. At present, FISH is the most widely used and best tested of the...

Was haben Mikrobiologie und Ökologie der Abwassertechnik zu bieten? Zur Optimierung der Abwasserreinigung sowie zur Früherkennung und Vermeidung von Störungen ist es notwendig, die Organismen zu kennen, von denen die Reinigungsleistung vollbracht wird, und zu wissen, welche Wechselwirkungen sie untereinander entwickeln und wie sich Veränderungen des Nährstoffangebots auf Zusammensetzung und Effektivität der Population auswirken. Darüberhinaus bietet die mikrobielle Ökologie auch Ansätze, die biologischen Ursachen von Schwimmschlamm, Blähschlamm und Schaumbildung besser zu verstehen und ihnen frühzeitig gezielt entgegenzuwirken. Anhand konkreter Beispiele werden Möglichkeiten und Grenzen klassischer und gentechnischer Methoden zur Charakterisierung der Abwassermikroorganismen demonstriert.
This title includes a number of Open Access chapters. The activated sludge process is one of the most versatile and commonly used wastewater treatment systems in the world. In the past, when industrial wastewater treatment focused on removing biological oxygen demand and suspended solids, waste water plants needed different processes and technology
The microbial complexity and the functions of the biomass present in activated sludge and biofilm systems were the subject matter of the 3rd Conference on Microorganisms in Activated Sludge and Biofilm Processes. Detailed knowledge of the identity, physiology and ecology of the microorganisms involved is central to any attempts to modify the composition of the biomass and hence optimise its performance. The Conference covered a wide range of topics dealing with the microbiology and microbial processes in activated sludge and biofilms, including sessions on newly identified microorganisms, microbial selection mechanisms and biomass storage processes. Many of these papers reported on the use o...
In recent years, a great variety of novel analytical methods has been developed to analyze composition, architecture and physico-chemical properties of microbial aggregates such as activated sludge flocs and biofilms. Simultaneously, new modeling approaches, aided by improved numerical simulation of the structure and function of these aggregates, have furthered our ability to understand their development and internal organization. The application of these novel analytical tools has led to fascinating discoveries, but at the same time has created a great deal of confusion in the engineering community. This volume is intended to bridge the gap that has emerged between science and engineering i...
Through a series of case histories, this unique volume illustrates the methodology and problems of population work with mammals. The contributors consider a broad range of techniques for estimating and monitoring population size of both land and marine mammals, and discuss methods for predicting their change. The difficulty of relating population dynamics to disease and to environmental change is also examined. Among the animals covered are rare and endangered species, and groups that are regarded as vectors of human disease.
