Описание: Biological nutrient removal (BNR), the removal of nitrogen and phosphorus from wastewater, is a complex process. Although the activated sludge process is an efficient technology for the removal of biochemical oxygen demand (BOD) and total suspended solids (TSS), it provides less-than-optimal conditions for the removal of nitrogen and phosphorus, and presents numerous challenges to the operator trying to satisfy the many requirements for several different groups of bacteria. In addition to satisfying the requirements there are numerous, highly variable operational conditions that impact BNR. These conditions include: changes in strength and composition of the wastewater, alkalinity and pH, temperature, and presence of inhibitory and toxic wastes. Even fluctuations in flows, especially from inflow and infiltration, can adversely impact the aerobic, anoxic, and anaerobic conditions needed for successful BNR. Of the three treatment processes, nitrification, denitrification, and enhanced biological removal, nitrification is often the most difficult to achieve. Therefore, a large portion of this book reviews nitrification. Operators of the activated sludge process need to understand the basic biological, chemical, and physical requirements for BNR in order to improve the performance of these treatment processes. An Operator’s Guide to Biological Nutrient Removal (BNR) in the Activated Sludge Process is intended to help operators in the monitoring, troubleshooting, and process control of BNR. Numerous tables and figures are included in the book to help the operator understand the biological and chemical reactions that are involved in BNR processes and how the reactions can be monitored for process control.Design of BNR processes is not addressed in this book. Design is addressed in numerous engineering publications. The book serves to help operators achieve permit compliance for nitrogen and phosphorus discharge limits and obtain cost-effective operation.

Описание:
With nanotechnology being a relatively new field, the questions regarding safety and ethics are steadily increasing with the development of the research. This book aims to give an overview on the ethics associated with employing nanoscience for products with everyday applications. The risks as well as the regulations are discussed, and an outlook for the future of nanoscience on a manufacturer’s scale and for the society is provided.
Ethics in nanotechnology is a valuable resource for, philosophers, academicians and scientist, as well as all other industry professionals and researchers who interact with emerging social and philosophical ethical issues on routine bases. It is especially for deep learners who are enthusiastic to apprehend the challenges related to nanotechnology and ethics in philosophical and social education.
This book presents an overview of new and emerging nanotechnologies and their societal and ethical implications. It is meant for students, academics, scientists, engineers, policy makers, ethicist, philosophers and all stakeholders involved in the development and use of nanotechnology.???
Over the past two decades, the rapid development of nanochemistry and nanotechnology has allowed the synthesis of various materials and oxides in the form of nanopowders making it possible to produce new energetic compositions and nanomaterials.
This book has a bottom-up structure, from nanomaterials synthesis to the application fields. Starting from aluminum nanoparticles synthesis for fuel application, it proposes a detailed state-of-the art of the different methods of preparation of aluminum-based reactive nanomaterials. It describes the techniques developed for their characterization and, when available, a description of the fundamental mechanisms responsible for their ignition and combustion. This book also presents the possibilities and limitations of different energetic nanomaterials and related structures as well as the analysis of their chemical and thermal properties. The whole is rounded off with a look at the performances of reactive materials in terms of heat of reaction and reactivity mainly characterized as the self-sustained combustion velocity. The book ends up with a description of current reactive nanomaterials applications underlying the promising integration of aluminum-based reactive nanomaterial into micro electromechanical systems.

This book proposes a new model, the Lean and Green Business Model (L&GBM), where the environmental aspect of sustainability is integrated with Lean thinking in order to create a way of thinking that contributes to and balances the three sustainability dimensions of people, profit, and planet. The model presented uses a kaizen approach that will help readers improve mass and energy flows in manufacturing environments that already possess a deployment level in applying Lean. The Green Factory: Creating Lean and Sustainable Manufacturing tells the story of how GKN, a major British multinational corporation with operations in more than 30 countries, developed and implemented a Lean and Green Business Model in two of its automotive facilities in Brazil. It provides practical insight into how GKN was able to develop and deploy Lean and Green in a manner that resulted in environmental and cost benefits in the automotive facilities that operated in Brazil's high-inflation environment. Detailing proven concepts and sustainable models derived from the first-hand experiences, the book supplies information against the backdrop of GKN's automotive manufacturing environment. The authors take an inside-out approach, describing the real issues Environmental Health & Safety professionals face when implementing sustainable manufacturing policies. The book covers the corporate issues of balancing profit with environmental concern and the behavioral issues of engaging the workforce to identify and reduce environmental waste. All the concepts and models presented in the book have come about through the authors' real life experiences in live kaizen events as well as their extensive academic research in the subject area.
