A-B processes: Towards Energy Self-sufficient Municipal Wastewater Treatment by Yu Liu,Jun Gu,Meng Zhang Pdf

The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.

Sustainable Treatment and Reuse of Municipal Wastewater by Menahem Libhaber,Alvaro Orozco Jaramillo Pdf

In many countries, especially in developing countries, many people are lacking access to water and sanitation services and this inadequate service is the main cause of diseases in these countries. Application of appropriate wastewater treatment technologies, which are effective, low cost (in investment and especially in operation and maintenance), simple to operate, proven technologies, is a key component in any strategy aimed at increasing the coverage of wastewater treatment. Sustainable Treatment and Reuse of Municipal Wastewater presents the concepts of appropriate technology for wastewater treatment and the issues of strategy and policy for increasing wastewater treatment coverage. The book focuses on the resolution of wastewater treatment and disposal problems in developing countries, however the concepts presented are valid and applicable anywhere and plants based on combined unit processes of appropriate technology can also be used in developed countries and provide to them the benefits described. Sustainable Treatment and Reuse of Municipal Wastewater presents the basic engineering design procedures to obtain high quality effluents by treatment plants based on simple, low cost and easy to operate processes. The main message of the book is the idea of the ability to combine unit processes to create a treatment plant based on a series of appropriate technology processes which jointly can generate any required effluent quality. A plant based on a combination of appropriate technology unit processes is still easy to operate and is usually of lower costs than conventional processes in terms of investment and certainly in operation and maintenance. Chapters in the book are organized in a practical and accessible way to: Demonstrate selected unit process of appropriate technology and provide the scientific basis, the equations and the parameters required to design the unit processes, with some innovations developed by the authors. Highlight design procedures for selected combined processes which are in use in developing countries. Propose an innovative Orderly Design Method (ODM), which is easy to follow by practicing engineers, using the equations and formulas developed, once the fundamentals of each unit and combined process have been established. Provide a numeric example for the basic design of each selected appropriate technology process for a city with a population of 20,000 using the ODM and an Excel program which will be provided to the readers for download from an online web page. This book is a valuable and practical resource for all wastewater treatment engineers in field and the operational managers of waste treatment facilities.

Innovative Wastewater Treatment & Resource Recovery Technologies: Impacts on Energy, Economy and Environment by Juan M. Lema,Sonia Suarez Martinez Pdf

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.

Sustainable Industrial Wastewater Treatment and Pollution Control by Maulin P. Shah Pdf

This book summarizes the advanced sustainable trends in removing toxic pollutants by environmental and biotechnological processes from both industrial wastewater and sewage wastewater. The book also provides an assessment of the potential application of several existing wastewater bioremediation techniques and introduces new cutting-edge technologies. Among other valuable information covered, here are the methods, procedures, materials (especially low-cost materials originating from industrial and agricultural waste), management of wastewater containing toxic pollutants, and valorization possibilities of waste resulting from the removal of toxic pollutants from wastewater. Tonnes of hazardous waste pollutants released by industries are a challenge worldwide. With the ever-growing population and shrinking landfill areas, managing the disposal of pollutants is a matter of severe concern. Industrial wastewater treatment, recycling, and reuse are serious issues in today’s context, not just to protect the environment from pollution, but also to conserve water resources so that water stress is reduced. This book is designed for engineers, scientists, and other professionals and serves as a good summary of the current state-of-the-art and innovative research challenges to control pollution for coming generations.

Total Energy Consumption for Municipal Wastewater Treatment by Robert Smith Pdf

Quantities of all forms of energy consumed for collection and treatment of municipal wastewater are estimated. Heat energy is equated to electrical energy by a conversion factor of 10,500 Btu/kwh. Total energy consumption, expressed as kwh/mg of wastewater treated, ranges from 2300-3700 kwh/mg. Energy used for construction of the treatment plant and the sewerage system represents 35-55% of the total energy consumed. The remainder used for plant operation is predominately (65-75%) electrical energy. The use of high efficiency aeration devices combined with good maintenance practices appears to offer the best opportunity for conservation of energy within the plant. Recovery of energy from the sludge produced at the plant can be accomplished by anaerobically digesting the sludge and using the digester gas as fuel for internal combustion engines. In large plants, when the sludge is sufficiently dewatered, it is also possible to recover energy by incinerating the dewatered sludge with production of steam in a waste heat boiler. The steam can then be used within the plant or expanded through a steam turbine to produce mechanical or electrical energy.
