Wastewater Sludge Processing

A practical guide to wastewater bacteria and the roles they perform in wastewater treatment Communicating material in a practical manner for operators and technicians who regulate and troubleshoot their wastewater treatment processes, Wastewater Bacteria discusses the effective control and proper operation of aerobic (activated sludge) and anaerobic (anaerobic digesters) biological treatment units to ensure that an adequate, active, and appropriate population of bacteria is present in each treatment unit. It is a hands-on guide to understanding the biology and biological conditions that occur at each treatment unit. Avoiding unnecessary technical jargon and chemical equations, Wastewater Bacteria, the fifth book in the Wastewater Microbiology Series, explores and explains: * Bacteria and the wastewater environment * Enzymes and sludge production * Nitrogen, phosphorus, and sulfur bacteria * Floc formation and filamentous organisms * Nitrification and denitrification * Sulfate reduction, fermentation, and methane production * Toxicity * Foam and malodor production The goal of Wastewater Bacteria is to enable plant operators to achieve the twofold basic objectives of wastewater treatment-to degrade organic wastes to a level where a significant, dissolved oxygen demand is not exerted upon receiving waters and to remove nutrients to levels where photosynthetic organisms in receiving waters are limited in their growth. This straightforward manual equips plant technicians to meet these objectives with essential information to understand the biological processes and organisms involved in wastewater treatment.

A thorough analysis of public policy and the Clean Water Act's effect on water quality in the U.S. Using water quality data and historical records from the past 60 years, this book presents the measured impact of the 1972 Clean Water Act on domestic waterways-ecologically, politically, and economically. Municipal Wastewater Treatment supports the hypothesis that the Act's regulation of wastewater treatment processes at publicly owned treatment works (POTW) and industrial facilities has achieved significant success. The authors' case is presented in: * Background information on the history of water pollution control and water quality management * Chapters addressing long-term trends in biochemical oxygen demand loadings from municipal wastewater plants and the «worst-case» dissolved oxygen levels in waterways downstream of point sources before and after the Clean Water Act * Nine case study assessments of long-term trends of pollutant loading water quality and environmental resources associated with POTW discharges Using long-term trends in dissolved oxygen as the key indicator of water quality improvements, this book provides a detailed retrospective analysis of the effectiveness of the water pollution control policies and regulations of the 1972 Clean Water Act. The successes of the Act that have been achieved over the past 30 years are placed in the historical context of the «Great Sanitary Awakening» of the 19th century and changes in public policies for water supply and water pollution control that have evolved during the 20th century to protect public health and the intrinsic value of aquatic resources. Case study sites include the Connecticut River, Hudson-Raritan Estuary, Delaware Estuary, Potomac Estuary, Upper Chattahoochee River, Ohio River, Upper Mississippi River, and Willamette River. Complete with end-of-chapter summaries and conclusions, Municipal Wastewater Treatment: Evaluating Improvements in National Water Quality is an essential book for engineers, scientists, regulators, and consultants involved in water quality management and wastewater treatment, as well as students of environmental engineering, environmental science, and public policy.

Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a ­variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption – the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.

A comprehensive guide to sludge management, reuse, and disposal When wastewater is treated, reducing organic material to carbon dioxide, water, and bacterial cells—the cells are disposed of, producing a semisolid and nutrient-rich byproduct called sludge. The expansion in global population and industrial activity has turned the production of excess sludge into an international environmental challenge, with the ultimate disposal of excess sludge now one of the most expensive problems faced by wastewater facilities. Written by two leading environmental engineers, Biological Sludge Minimization and Biomaterials/Bioenergy Recovery Technologies offers a comprehensive look at cutting-edge techniques for reducing sludge production, converting sludge into a value-added material, recovering useful resources from sludge, and sludge incineration. Reflecting the impact of new stringent environmental legislation, this book offers a frank appraisal of how sludge can be realistically managed, covering key concerns and the latest tools: Fundamentals of biological processes for wastewater treatment, wastewater microbiology, and microbial metabolism, essential to understanding how sludge is produced Prediction of primary sludge and waste-activated sludge production, among the chief design and operational challenges of a wastewater treatment plant Technologies for sludge reduction, with a focus on reducing microbial growth yield as well as enhancing sludge disintegration The use of anerobic digestion of sewage sludge for biogas recovery, in terms of process fundamentals, design, and operation The use of the microbial fuel cell (MFC) system for the sustainable treatment of organic wastes and electrical energy recovery
