The world is facing a drinking water crisis. Besides continuous population growth, uneven distribution of water resources and periodic droughts have forced scientists to search for new and effective water treatment, remediation and recycling technologies. Therefore, there is a great need for the development of suitable, inexpensive and rapid wastewater treatment and reuse or conservation methods. This title discusses different types of wastewater treatment, remediation and recycling techniques, like adsorption, membrane filtration and reverse osmosis. It also�provides guidance for the selection of the appropriate technologies or their combinations for specific applications so that one can select the exact and accurate technology without any problem. The book comprises detailed discussion on the application of various technologies for water treatment, remediation and recycling technologies and provides an update on the development in water treatment, detailed analysis of their features and economic analysis, bridging the current existing information gap. Each chapter�is also documented by references and updated citations.

Comprehensive resource presenting benefits, opportunities, and challenges in the application of nanotechnology in farming Nanotechnology and Microbiology for Sustainable Agriculture provides a comprehensive overview of the diverse roles of nanotechnology and microbiology for sustainable agriculture, highlighting the potential synergistic applications of these two rapidly advancing scientific domains to address pressing challenges in the field. This book shows how these technologies can offer novel solutions for soil health management, enhanced nutrient delivery, pest control, stress tolerance, and crop productivity. The chapters in this book are organized into several thematic sections. Topics explored include the synergistic effects of phosphorus-solubilizing microbes and nanoformulations to improve plant growth and soil fertility, the role of fungi in the production of bioactive compounds and nanomaterial development, the integration of plant and soil microbiomes with nano-interventions to support food safety, nutrient cycling, and agroecosystem resilience, the biosynthetic capabilities of actinomycetes in producing antimicrobial and growth-promoting nanomaterials, and the role of nanotechnology in enhancing GMO functionality, safety assessment, and public perception in food systems. Contributed to by international experts in their respective fields, Nanotechnology and Microbiology for Sustainable Agriculture includes information on: Nano-biotechnological solutions for remediating pesticides, hydrocarbons, and heavy metals from soils and water bodiesGreen-synthesized nanomaterials from biological sources with potential for managing plant pathogens in a sustainable mannerAdvanced nanostructures for immobilizing beneficial microbes and enzymes to enhance their agricultural efficiency and stabilityThe formulation, mode of action, and environmental benefits of nanopesticides compared to conventional chemical pesticidesNanobiosensor technologies for real-time monitoring of soil quality, pathogens, pollutants, and nutrient levelsNanotechnology and Microbiology for Sustainable Agriculture is an essential up-to-date resource for researchers, scientists, students, industry professionals, and government agencies interested in microbial biotechnology, bioprocess engineering, agriculture, pest control, and nano-fertilizer manufacturing.

A special workshop on scale problems in hydrology was held at Princeton University, Princeton, New Jersey, during October 31-November 3, 1984. This workshop was the second in a series on this general topic. The proceedings of the first workshop, held in Caracas, Venezuela, in January 1982, appeared in the Journal of Hydrology (Volume 65:1/3, 1983). This book contains the papers presented at the second workshop. The scale problems in hydrology and other geophysical sciences stem from the recognition that the mathematical relationships describing a physical phenomenon are mostly scale dependent in the sense that different relationships manifest at different space-time scales. The broad scientific problem then is to identify and for­ mulate suitable relationships at the scales of practical interest, test them experimen­ tally and seek consistent analytical connections between these relationships and those known at other scales. For example, the current hydrologic theories of evaporation, infiltration, subsurface water transport and water sediment transport overland and in channels etc. derive mostly from laboratory experiments and therefore generally apply at "small" space-time scales. A rigorous extrapolation of these theories to large spatial and temporal basin scales, as mandated by practical considerations, appears very difficult. Consequently, analytical formulations of suitable hydrologic theories at basin wide space-time scales and their experimental verification is currently being perceived to be an exciting and challenging area of scientific research in hydrology. In order to successfully meet these challenges in the future, this series of workshops was initiated.
