Wastewater Sludge Processing


Book Description

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.




Dewatering Biosolids


Book Description

FROM THE PREFACE The processes used to remove water from biosolids and change their form from a liquid to a damp solid are critical to the operation of other downstream processes in wastewater treatment. An ideal dewatering operation would capture all of the biosolids solids at minimum cost and the resultant dry biosolids solids or cake would be capable of being handled without causing unnecessary problems. Process reliability, ease of operation, and compatibility with the treatment plant environment are also optimum. This text is designed to provide a detailed look at several dewatering options. It must be pointed out, however, that this text takes a strong, biased view toward centrifugation as the dewatering process that is most reliable, maintenance free, cost effective, and capable of producing the highest quality end-product when compared to the other options in a holistic manner. Therefore, the underlying theme of this text is wrapped around the premise that it is better to centrifuge it! Having said this, it must also be pointed out that all major biosolids dewatering processes are discussed in this text, in detail. Several examples of actual operating systems are presented, and preventive maintenance and cost considerations are presented and discussed. In recent years there has been a tendency in some technical texts like this one to focus on the theoretical and laboratory analyses of dewatering operations. While such research and documented findings can lead to improved understanding of the scientific and engineering concepts associated with dewatering biosolids, this text is presented in such a fashion so as to be user-friendly. It is an operator's text that can also afford the decision-maker the opportunity to make informed choices about selecting a dewatering system for his/her plant use. Dewatering Biosolids will be of interest to people in all aspects of wastewater plant operation. Useful as a handbook for operators, this plain language text is also of importance to anyone considering altering or adapting their wastewater operating system.

Concentrate Management in Desalination


Book Description

Prepared by the Task Committee on the Development of Prestandards for Concentrate Management Case Studies of the Desalination and Water Reuse Technical Committee of the Water, Wastewater, and Stormwater Council of the Environmental and Water Resources Institute of ASCE.Concentrate Management in Desalination: Case Studies, Second Edition, reviews the state-of-the-practice for managing concentrate streams resulting from desalination processes.Concentrate management and disposal in desalination pose environmental and cost concerns--and often determine whether a desalination project is viable, especially for inland communities. This book examines many facets of concentrate management in desalination, including process design and configuration; regulatory setting; environmental, climate change, and sustainability issues; and economic evaluation of projects. Thirteen case studies are offered to demonstrate different techniques for disposing of concentrates associated with the following types of projects: ocean and bays discharge, sanitary sewer or surface water disposal, deep-well injection, zero liquid discharge (ZLD) or near ZLD, and land disposal and/or evaporation ponds.Environmental engineers, water practitioners and managers responsible for the design, operation, research, and evaluation of regional desalination and water reuse facilities will find a wealth of practical information in this updated and expanded edition.
