Intended for advanced students and practitioners of wastewater engineering, this text explains the theory and quantitative rationale for treating wastewater and industrial sludges, with public safety and efficiency in mind. It offers important information on various practices for safe and legal sludge disposal.

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

Reap the benefits of sludge The processing of wastewater sludge for use or disposal has been a continuing challenge for municipal agencies. Yet, whensludge is properly processed, the resulting nutrient-rich product--biosolids--can be a valuable resource for agriculture and other uses. Wastewater Sludge Processing brings together a wide body of knowledge from the field to examine how to effectively process sludge to reap its benefits, yet protect public health. Presented in a format useful as both a reference for practicing environmental engineers and a textbook for graduatestudents, this book discusses unit operations used for processing sludge and the available methods for final disposition of the processed product. Topics discussed include sludge quantities and characteristics, thickening and dewatering, aerobicand anaerobic digestion, alkaline stabilization, composting, thermal drying and incineration, energy consumption, and the beneficial use of biosolids. COMPREHENSIVE IN ITS COVERAGE, THE TEXT: * Describes new and emerging technologies as well as international methods * Compares different types of sludge processing methods * Explains both municipal and industrial treatment technologies Written by authors with decades of experience in the field, Wastewater Sludge Processing is an invaluable tool for anyone planning, designing, and implementing municipal wastewater sludge management projects.
