Water professionals are responsible for shaping and sometimes changing consumers' perceptions about the value of water. Consumers can mistakenly undervalue water's worth by assuming it should be provided at no cost to the public. This book by Melanie Goetz outlines how water professionals can encourage customers to appreciate water as the precious commodity it is by driving the message that it needs to be paid for just like other valuable services. The tactics outlined can be especially useful during situations such as advocating for proposed rate hikes, or when conservation measures are needed. Goetz goes into depth about the consumer behavior and psychology that drives people's understanding of worth. Communicating Water's Value also includes "success stories" from various utilities and corporations who implemented strategies that effectively shaped and changed the public's perception of the value of water.
Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison - either practical or based on simulation - is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants. The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants. Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) - with focus on benchmarking of process monitoring tasks - and the plant-wide Benchmark Simulation Model no. 2 (BSM2).

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.

The global chemical and petroleum industries have always had the challenge of disposing of chemical wastes, by-products, and residuals, but with traditional techniques such as deep well injection and incineration proving flawed, the need for disposal by legal, safe and economically effective means has never been greater. Increasingly, the need to produce without pollution is the preferred model for industry, and the strategy of waste minimization is seen as the best way forward. This is particularly relevant in the petrochemical and chemical industries, where large quantities of hazardous and toxic wastes are produced which can pose formidable disposal problems. Covering the essentials of treatment, recovery and disposal of waste, as well as the requirements for process design and engineering of equipment and facilities in the chemical and petroleum industries, this book includes chapters on: * Wastewater Treatment * Physical Unit Operations * Chemical Treatment * Biological Treatment * Wastewater Treatment in Unconventional Oil and Gas Industries * Wastewater Sewer Systems * Sewage Treatment * Solid Waste Treatment and Disposal Primarily aimed at researchers and advanced students in chemical, petroleum, and environmental fields as well as those in civil engineering, this book should also provide a unique reference for industry practitioners and anyone interested in chemical and petroleum waste treatment and disposal.

Management of wet weather flows in the wastewater collection and treatment system has remained one of the most intractable problems for wastewater managers, who have struggled to get approvals for affordable wet weather flow management plans. With the U.S. Environmental Protection Agency's (U.S. EPA's) introduction of the Integrated Municipal Stormwater and Wastewater Planning Approach Framework (2012a), there is the potential that many more wet weather management plans will incorporate stormwater management, in addition to the regulated components of wastewater conveyance and treatment systems. Guide for Municipal Wet Weather Strategies provides a clear and common understanding of what constitutes generally accepted planning and engineering practices and a process for selecting the optimum wet weather management option. All of this supports the proposition that to effectively manage flows and protect human health and the environment, the approach should be holistic and watershed-based. Guide for Municipal Wet Weather Strategies is intended not only for owners, planners, designers, and operators of municipal wastewater collection and treatment systems, but for regulators and other stakeholders involved in managing wet weather flows.

The rapid development of nanoscience enables a technology revolution that will soon impact virtually every facet of the water sector. Yet, there is still too little understanding of what nanoscience and nanotechnology is, what can it do and whether to fear it or not, even among the educated public as well as scientists and engineers from other disciplines. Despite the numerous books and textbooks available on the subject, there is a gap in the literature that bridges the space between the synthesis (conventional and more greener methods) and use (applications in the drinking water production, wastewater treatment and environmental remediation fields) of nanotechnology on the one hand and its potential environmental implications (fate and transport of nanomaterials, toxicity, Life Cycle Assessments) on the other. Nanotechnology for Water and Wastewater Treatment explores these topics with a broad-based multidisciplinary scope and can be used by engineers and scientists outside the field and by students at both undergraduate and post graduate level.
The volume of waste produced by human activity continues to grow, but steps are being taken to mitigate this problem by viewing waste as a resource. Recovering a proportion of waste for re-use immediately reduces the volume of landfill. Furthermore, the scarcity of some elements (such as phosphorous and the rare-earth metals) increases the need for their recovery from waste streams. This volume of Issues in Environmental Science and Technology examines the potential resource available from several waste streams, both domestic and industrial. Opportunities for exploiting waste are discussed, along with their environmental and economic considerations. Landfill remains an unavoidable solution in some circumstances, and the current situation regarding this is also presented. Other chapters focus on mine waste, the recovery of fertilisers, and the growing potential for compost. In keeping with the Issues series, this volume is written with a broad audience in mind. University students and active researches in the field will appreciate the latest research and discussion, while policy makers and members of NGOs will benefit from the wealth of information presented.

Mathematical modelling of activated sludge systems is used widely for plant design, optimisation, training, controller design and research. The quality of simulation studies varies depending on the project objectives, finances and expertise available. Consideration has to be given to the model accuracy and the amount of time required carrying out a simulation study to produce the desired accuracy. Inconsistent approaches and insufficient documentation make quality assessment and comparison of simulation results difficult or almost impossible. A general framework for the application of activated sludge models is needed in order to overcome these obstacles. The genesis of the Good Modelling Practice (GMP) Task Group lies in a workshop held at the 4th IWA World Water Congress in Marrakech, Morocco where members of research groups active in wastewater treatment modelling came together to develop plans to synthesize the best practices of modellers from all over the world. The most cited protocols were included in the work, amongst others from: HSG (Hochschulgruppe), STOWA, BIOMATH and WERF. The goal of the group is to set up an internationally accepted framework to deal with the ASM type models in practice. This framework shall make modelling more straightforward and systematic to use especially for practitioners and consultants. Additionally, it shall help to define quality levels for simulation results, a procedure to assess this quality and to assist in the proper use of the models. The framework will describe a methodology for goal-oriented application of activated sludge models demonstrated by means of a concise guideline about the procedure of a simulation study and some illustrative case studies. The case studies shall give examples for the required data quality and quantity and the effort for calibration/validation with respect to a defined goal. The final report will include an extended appendix with additional information and details of methodologies. Additional features in Guidelines for Using Activated Sludge Models include a chapter on modelling industrial wastewater, an overview on the history, current practice and future of activated sludge modelling and several explanatory case studies. It can be used as an introductory book to learn about Good Modelling Practice (GMP) in activated sludge modelling and will be of special interest for process engineers who have no prior knowledge of modelling or for lecturers who need a textbook for their students. The STR can also be used as a modelling reference book and includes an extended appendix with additional information and details of methodologies. Scientific and Technical Report No. 22

Sampllng Fundamental Aspects 2 Sampling: Fundamental aspects Reimar Leschber Institut fuer Wasser-, Boden- und Lufthygiene des Bundesge- sundheitsamtes, Berlin-Dahlem, Federal Republic of Germany Chairman of Working Party 2, COST 681 Protection of the environment increasingly requires the de- velopment of a recycling society using 'secondary raw ma- terials' instead of natural resources wherever possible. Among the methods of recycling the agricultural use of sludge is a traditional one and a good example with a long history of a meanlngful use of waste material. Increasing demands of water pollution control in the last de- cades leading to intensified and extended sewage treatment processes and thus to an increase of the sludge quantity have caused problems in this field in general. In addition, there were local problems of industrial pollution which have led to an increase of harmful substances in municipal sewage sludges. So, when the Concerted Action COST 68 was set up to study the beneficial and harmful effects of the agricultural use of sludge, investigation of harmful substances in the sludges and their environmental effects was 9ne of the main tasks of work. Although the progress of analytical techniques enabled the environmental authorities and institutions to determine harmful substances in sludges with great accuracy, it became clear that unsatisfactory results and an incomplete reproduc- ibility of analytical findings often were not due to shortcom- ings in the analytical procedure itself but to a preceding in- vestigation step: Improper sampling and sample preparation.
