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. Table of Contents Introduction: Nanotechnology for water and wastewater treatment: potential and limitation; Characteristics and properties of nanoparticles; Physical and chemical analysis of nanoparticles; Fate and transport of nanoparticles/nanomaterials, toxicity studies; Nanoparticles and bioremediation; Nanosorbents; Effective Phosphate Removal Using Ca-based Layered Double Hydroxide Materials; Mg(OH)2 nanoadsorbent during Treating the Low Concentration of Cr; Nano catalysts; Visible-light doped titania for water purification: nitrogen and silver doping; Doping of Pd nanocatalysts for PCB removal; The use of bimetallic nanosystems to remove POPs from soils and sediments"; Nanomaterials for disinfection and microbial control; Microbial manufactured silver nanoparticles for water disinfection; Electrospun nanofibers for Point-of-Use Water Treatment; Nanomaterials to enhance filtration; Metalic and ceramic microreactors; Enzyme-Immobilized Nanofiltration Membrane To Mitigate Biofouling Based on Quorum Quenching; Biomimetic membranes for water filtration; Nano sensors ; Functionalised graphene: a novel platform for biosensors; Lab-on-a-Chip Interferometric Biosensor Nanotechnology; Nanosensors for pathogens; Nanomanufacturing: Materials Design and Production; Green synthesis of nanoparticles and nanocatalysts; Plant-based nanoparticle manufacturing.

The world’s fresh water supplies are dwindling rapidly—even wastewater is now considered an asset. By 2025, most of the world's population will be facing serious water stresses and shortages. Aquananotechnology: Global Prospects breaks new ground with its informative and innovative introduction of the application of nanotechnology to the remediation of contaminated water for drinking and industrial use. It provides a comprehensive overview, from a global perspective, of the latest research and developments in the use of nanotechnology for water purification and desalination methods. The book also covers approaches to remediation such as high surface area nanoscale media for adsorption of toxic species, UV treatment of pathogens, and regeneration of saturated media with applications in municipal water supplies, produced water from fracking, ballast water, and more. It also discusses membranes, desalination, sensing, engineered polymers, magnetic nanomaterials, electrospun nanofibers, photocatalysis, endocrine disruptors, and Al13 clusters. It explores physics-based phenomena such as subcritical water and cavitation-induced sonoluminescence, and fog harvesting. With contributions from experts in developed and developing countries, including those with severe contamination, such as China, India, and Pakistan, the book’s content spans a wide range of the subject areas that fall under the aquananotechnology banner, either squarely or tangentially. The book strongly emphasizes sorption media, with broad application to a myriad of contaminants—both geogenic and anthropogenic—keeping in mind that it is not enough for water to be potable, it must also be palatable.

“It is good that Mr. Mulira tells the story of the unknown black Ugandan Diaspora. I hope this book encourages more books written by others who fi nd themselves living away from their beautiful homeland.” - M/s Yasmin Alibhai –Brown, writer for the Guadian, London, U.K. “Th is is a very interesting and informative book. I enjoyed reading it and learned not only the life stories and contributions of Ugandan immigrants in Canada but also the history of Canadian immigration.” Ugandan immigrants in Canada have become more visible in recent years. Yet, it is likely that only a small percentage of Canadian citizens are well informed of the history and interesting traditions of these people from East Africa. Th e actual number of Ugandan immigrants currently living in Canada is uncertain but could range from 10,000 to 20,000 people. Most of the Ugandan immigrants in Canada live in major metropolitan areas like greater Toronto, Montreal, Vancouver, Edmonton, Calgary and Winnipeg. In the U.S. where the number is larger, they are also mostly concentrated in New York City, Boston, Los Angeles, Chicago and other large industrial cities.

Microbiology of Drinking Water Production andDistribution addresses the public health aspects of drinkingwater treatment and distribution. It explains the different watertreatment processes, such as pretreatment, coagulation,flocculation, sedimentation, filtration, disinfection, and theirimpacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distributionsystems—microorganisms form biofilms within distributionsystems that allow them to flourish. Various methodologies havebeen proposed to assess the bacterial growth potential in waterdistribution systems. Microbiology of Drinking Water Production and Distributionalso places drinking water quality and public health issues incontext; it addresses the effect of bioterrorism on drinking watersafety, particularly safeguards that are in place to protectconsumers against the microbial agents involved. In addition, thetext delves into research on drinking water quality in developingcountries and the low-cost treatment technologies that could savelives. The text also examines the microbiological water quality ofbottled water, often misunderstood by the public at large.

Labeled either as the "next industrial revolution" or as just "hype," nanoscience and nanotechnologies are controversial, touted by some as the likely engines of spectacular transformation of human societies and even human bodies, and by others as conceptually flawed. These challenges make an encyclopedia of nanoscience and society an absolute necessity. Providing a guide to what these understandings and challenges are about, the Encyclopedia of Nanoscience and Society offers accessible descriptions of some of the key technical achievements of nanoscience along with its history and prospects. Rather than a technical primer, this encyclopedia instead focuses on the efforts of governments around the world to fund nanoscience research and to tap its potential for economic development as well as to assess how best to regulate a new technology for the environmental, occupational, and consumer health and safety issues related to the field. Contributions examine and analyze the cultural significance of nanoscience and nanotechnologies and describe some of the organizations, and their products, that promise to make nanotechnologies a critical part of the global economy. Written by noted scholars and practitioners from around the globe, these two volumes offer nearly 500 entries describing the societal aspects of nanoscience and nanotechnology. Key Themes - Art, Design, and Materials - Bionanotechnology Centers - Context - Economics and Business - Engagement and the Public - Environment and Risk - Ethics and Values - Geographies and Distribution - History and Philosophy - Integration and Interdisciplinarity - Nanotechnology Companies - Nanotechnology Organizations
