This professional book deals with belt drying of sewage sludge, mainly of municipal but also of industrial origin. The wastewater treatment resulting in sludge production is briefly described. The types of sludge and their degree of stabilization is treated in depth as they have a high impact on their suitability for belt drying and the necessary exhaust air treatment. Different belt drying systems with or without condensing units and with extruding of dewatered sludge or partial recirculation of dried sludge are presented. Specific water evaporation and energy demand are tabulated for each dryer system on basis of indications of dryer manufacturers, measurements or information of dryer operators. Different sources for thermal energy are stipulated and complete systems of energy supply with internal or external usage of exhaust energy described. Occurring gas compounds in dryer exhaust air and their special features are mentioned in depth. The components and complete systems for exhaust air cleaning are discussed also in their efficiency of removal of individual odorous gas components or of total amount of volatile organic compounds. Conveying systems and storage of dewatered sludge as well as of dried sludge are described together with the related safety issues. Dryer control as well as ATEX, SIL and HAZOP issues and economic aspects are discussed briefly in individual chapters. The book will be useful for engineering enterprises and consultants designing belt drying systems for sludge, but will also transfer useful information to operators. Also authorities dealing with the permission of sludge drying plants will find important aspects with regard to environmental protection and reasonable economic and continuous operation under safe conditions.

Das Fachbuch behandelt die Theorie und Praxis der Bandtrockner sowie ihre Anwendung in zahlreichen Einsatzgebieten wie Landwirtschaft, Lebensmittelindustrie, chemischer Industrie, Pharmazie, Grundstoffindustrie, Entsorgungswirtschaft und Abwasserreinigung. Es bietet Hinweise über die verfahrenstechnische und konstruktive Auslegung sowie den Betrieb der Anlagen. Für Berechnungen stehen Stoffwerte von industriellen Trocknungsgütern und von Trocknungsgasen zur Verfügung. Der Leser ist so in der Lage, mit Hilfe des Buches eine erste grobe Berechnung seines trocknungstechnischen Problems durchzuführen. Vielfach sind auch Zahlenwertgleichungen für Rechnerprogrammierungen angegeben. Die computerunterstützte Optimierung wird ebenso wie die Simulation der Strömung in Bandtrocknern behandelt.  Auch werden die Möglichkeiten der Energieeinsparung sowie der Abwärmenutzung hervorgehoben und wichtige Gesichtspunkte wie Arbeitssicherheit und Umweltschutz angesprochen. Der Autor verfügt über eine langjährige Erfahrung in Forschung und Industrie.
