Описание: This thesis examines the feasibility of using silver nanoparticles (AgNPs) as a viable disinfectant. It explores the opportunities and challenges of using AgNPs as an antimicrobial agent, and includes the latest research findings. It compares three kinds of AgNPs with regard to their antibacterial and antiviral effects; their sustainability in real water matrices; and their antiviral mechanisms. The outcome of this research equips the water industry with a better understanding of the capacity, extent and mechanisms of nanosilver disinfection. It is of interest to graduate students, academics and researchers in the area of nanotechnology and environmental engineering.
Описание: Water is one of the most important resources of all , Businesses, communities, and ecosystems everywhere depend on clean freshwater to survive and prosper. When the same source of water is shared for economic, social and environmental causes it becomes the responsibility of every sector to develop a sustainable water strategy beneficial for all. Like agriculture and domestic use Industries also consume great amount of water which is generally sourced from the common environmental resource shared by the natural and thuman communityies. While utilising water corporates have a responsibility to understand the source of water, its quantum and vulnerability so that conflicts among different stakeholders can be avoided. While doing so the corporate managers will face many challenges coming out of resource assessment, water accounting, water sharing, water disclosure and compliance and different government statutes and law of the land. Corporations are now facing diverse water risks, including changing allotments, more stringent water-quality regulations, growing community interest and control over local resources, and increased public scrutiny of water-related activities. Another great challenge for the industries is the gradual decline of water resource in different part of the world due to increase in demand, change in landscape, climate change etc. The industries now should face not only the competition in resource sharing but also the impacts of climate change. The term efficient water use will be applied to those businesses which have minimised the water use and properly protected the source water, used technologies and water management system that minimises the water requirement and complies all necessary norms and statues regarding maintaining the water quality and quantity. Water stewardship implies that a corporate not only manages its own water but it also integrates different stakeholders in the management process and develops an integrated system where water sharing is equitable, careful, and sustainable. While dealing with challenges in water management corporate managers will encounter opportunities that will lead them in developing a sustainable water strategy.The aim of this book is to offer a water resource management plan for industries which is directly implementable and consistent with the Water Framework Directives of different countries with a special emphasis on developing countries. The contributor, who is a leading world expert in these fields, develops an integrated water resources management plan for the industries which is economically efficient, socially equitable and environmentally sustainable. The book offers explicit technical and investment solutions, socioeconomic and legal instruments and recommendations for institutional restructuring. The introductory chapter describes the water situation throughout the world and how the industries are sharing the resource and how conflicts are developing between industries and ecosystem. In the first chapter the author describes a hydro-ecological approach of water resource management. The modalities and methods of assessment of source water has been discussed in this chapter along with an introduction to the basic concepts for understanding of water resource. Chapter 2 introduces the case study area highlighting the particular pressures and impacts as well as the environmental functions and values of sustainable water resource management. Chapter 3 deals with corporate water strategy for water security. In this chapter water security has been defined as the availability of an acceptable quantity and quality of water for health, livelihoods, ecosystems and production, coupled with an acceptable level of water related risks to people, environments and economies. Water security has always been a societal priority — in its absence people and economies have remained vulnerable and poor. How the corporate should handle the emerging demands, social

Описание: Agricultural pollution (with nitrates and pesticides) is one of the biggest threats to drinking water resources. Three national case studies (Germany, The Netherlands, and the United Kingdom) analyse these efforts within the context of problematical national agricultural policy and the need to implement EU directives on water quality.

Описание:
How and why branded bottles of water have insinuated themselves into our daily lives, and what the implications are for safe urban water supplies.
How did branded bottles of water insinuate themselves into our daily lives? Why did water become an economic good -- no longer a common resource but a commercial product, in industry parlance a "fast moving consumer good," or FMCG? Plastic Water examines the processes behind this transformation. It goes beyond the usual political and environmental critiques of bottled water to investigate its multiplicity, examining a bottle of water's simultaneous existence as, among other things, a product, personal health resource, object of boycotts, and part of accumulating waste matter. Throughout, the book focuses on the ontological dimensions of drinking bottled water -- the ways in which this habit enacts new relations and meanings that may interfere with other drinking water practices.
The book considers the assemblage and emergence of a mass market for water, from the invention of the polyethylene terephthalate (PET) bottle in 1973 to the development of "hydration science" that accompanied the rise of jogging in the United States. It looks at what bottles do in the world, tracing drinking and disposal practices in three Asian cities with unreliable access to safe water: Bangkok, Chennai, and Hanoi. And it considers the possibility of ethical drinking, examining campaigns to "say no" to the bottle and promote the consumption of tap water in Canada, the United States, and Australia.
Описание: This book provides a systematic account of major concepts and methodologies for data-driven models and uses them to deal with a wide range of problems in the field of water resources and environmental engineering.
