This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natural waste treatment, this text provides a thorough explanation on how soil and plants can successfully sustain microbial populations in the treatment of wastewater. Determining that natural systems cost less to construct and operate, and require less energy than mechanical treatment alternatives, this book also explains how these processes produce lower amounts of residual solids, and use little or no chemicals. What’s New in the Second Edition: This revised edition includes current design and regulatory and operational developments in the natural wastewater treatment field. It provides detailed examples and analyses along with significant operational data in each chapter. It also considers how processes provide passive treatment with a minimum of mechanical elements, and describes new approaches to partially mixed ponds, including dual-powered aeration ponds. Introduces the planning procedures and treatment mechanisms responsible for treatment in ponds, wetlands, land application, and soil absorption systems Provides new case studies of constructed wetlands and water reuse systems Presents design criteria and methods of pond treatment and pond effluent upgrading Describes constructed wetlands design procedures, process applications, treatment performance data, and land treatment concepts and design equations Includes information on constituents of emerging concern (CEC) and their fate in natural systems The text discusses wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. It describes residuals and biosolids management, including nitrogen removal pretreatment methods, and uses U.S. customary and metric units in all chapters. It presents case studies of new applications of natural systems and includes worked examples of design equations for ponds and land treatment. It also provides a biosolids regulatory update from a top EPA scientist, and algae reduction technologies for ponds and wetlands. Designed for practicing wastewater engineers and scientists involved in the planning, design, and operation of ponds, wetlands, land treatment, biosolids, and onsite soil-based treatment systems, the book integrates many natural treatment systems into one single source.

Varying degrees of environmental impact by sewage sludge disposals alternatives, present challenges for waste management practice and policy. Many regulating bodies throughout the world are implementing measures which actively promote environmentally sound and economically viable routes to convert this waste into a valuable resource. These provide opportunities, but at the same time, given the nature of the material and obstacles that may exist, require that responsible and proven practices are followed. This book presents the proceedings of an International Symposium organised by the Concrete Technology Unit, University of Dundee, which brings together some of the worlds leading experts in the field of sewage sludge recycling.

Advanced Oxidation Processes (AOPs) have gained attention rapidly worldwide since they have been proven to be effective in the removal of wide spectrum of organic and inorganic contaminants from water and soil. However, the issues related to the formation of oxidation intermediates which may be more toxic than parent compounds as well as the operating costs are the main obstacles to a wider spread at full scale. This volume is addressed to researchers and professionals with a background in environmental science and engineering. The objective is to provide them with knowledge about AOPs related applications such as fundamentals and technology, analytical characterization of emerging contaminants and oxidation by products, ecotoxicity and biodegradability tests, urban and industrial wastewater treatment, sludge treatment and reduction, soil treatment, solar driven AOPs.

This National Academy of Sciences report describes ways to exploit aquatic weeds for grazing, and by harvesting and processing for use as compost, animal feed, pulp, paper, and fuel. The book also describes utilization for sewage and industrial wastewater.Aquatic weeds have always existed, but in recent decades their effects have been magnified by man?s more intensive use of natural water bodies - his modifying them into canals and dams, polluting them with farm and city wastewaters, and introducing aggressive plant species into new locations. These plants, among the most prolific on earth, grow luxuriantly in the tropics, weigh hundreds of tons per hectare, and can be a serious hindrance to a nation?s development efforts. Eradication of the weeds has proved impossible, and even reasonable control is difficult. Turning these weeds to productive use would be desirable, but only limited research has been carried out.This report examines methods for controlling aquatic weeds and using them to best advantage, especially those methods that show promise for less-developed countries. It emphasizes techniques for converting weeds for feed, food, fertilizer, and energy production. It examines, for example, biological control techniques in which herbivorous tropical animals (fish, waterfowl, rodents, and other mammals) convert the troublesome plants directly to meat.
