Development in Wastewater Treatment Research and Processes


Book Description

Removal of Emerging Contaminants from Wastewater through Bio-nanotechnology showcases profiles of the nonregulated contaminants termed as "emerging contaminants, which comprise industrial and household persistent toxic chemicals, pharmaceuticals and personal care products (PPCPs), pesticides, surfactants and surfactant residues, plasticizers and industrial additives, manufactured nanomaterials and nanoparticles, microplastics, etc. that are used extensively in everyday life. The occurrence of "emerging contaminants in wastewater, and their behavior during wastewater treatment and production of drinking water are key issues in the reuse and recycling of water resources. This book focuses on the exploitation of Nano-biotechnology inclusive of the state-of-the-art remediate strategies to degrade/detoxify/stabilize toxic and hazardous contaminants and restore contaminated sites, which is not as comprehensively discussed in the existing titles on similar topics available in the global market. In addition, it discusses the potential environmental and health hazards and ecotoxicity associated with the widespread distribution of emerging contaminants in the water bodies. It also considers the life cycle assessment (LCA) of emerging (micro)-pollutants with suitable case studies from various industrial sources. - Provides natural and ecofriendly solutions to deal with the problem of pollution - Details underlying mechanisms of nanotechnology-associated microbes for the removal of emerging contaminants - Describes numerous successful field studies on the application of bio-nanotechnology for eco-restoration of contaminated sites - Presents recent advances and challenges in bio-nanotechnology research and applications for sustainable development - Provides authoritative contributions on the diverse aspects of bio-nanotechnology by world's leading experts




Hybrid Nature


Book Description

A history of of the industrial ecosystem that focuses on the biological sewage treatment plant as an early example. Biological sewage treatment, like electricity, power generation, telephones, and mass transit, has been a key technology and a major part of the urban infrastructure since the late nineteenth century. But sewage treatment plants are not only a ubiquitous component of the modern city, they are also ecosystems--a hybrid variety that incorporates elements of both nature and industry and embodies multiple contradictions. In Hybrid Nature, Daniel Schneider offers an environmental history of the biological sewage treatment plant in the United States and England, viewing it as an early and influential example of an industrial ecosystem. The sewage treatment plant relies on microorganisms and other plants and animals but differs from a natural ecosystem in the extent of human intervention in its creation and management. Schneider explores the relationship between society and nature in the industrial ecosystem and the contradictions that define it: the naturalization of industry versus the industrialization of nature; the public interest versus private (patented) technology; engineers versus bacterial and human labor; and purification versus profits in the marketing of sewage fertilizer. Schneider also describes biotechnology's direct connections to the history of sewage treatment, and how genetic engineering is extending the reaches of the industrial ecosystem to such "natural" ecosystems as oceans, rivers, and forests. In a conclusion that shows how industrial ecosystems continue to evolve, Schneider discusses John Todd's Living Machine, a natural purification method of sewage treatment, as the embodiment of the contradictions of the industrial ecosystem.

Professionals in the wastewater industry will also find this a handy reference.




Water Purification and Management


Book Description

One of the major challenges for many Mediterranean and other countries is finding viable solutions to tackle water shortage. Some of the major water quality constraints derive from the high salinity of groundwater and from pollution sources such as: untreated domestic sewage, fertilizers and pesticides from irrigation drainage, industrial effluents, and solid waste disposal. Wastewater treatment processes involving physico-chemical and biological treatment, chemical oxidation, membrane technologies, along with methods of solids concentration and disposal are of special relevance in dealing with these problems. This volume contains selected lectures presented at the NATO ADVANCED TRAINING COURSE held in Oviedo (November 15-21, 2009) and sponsored by the NATO Science for Peace and Security (SPS) Programme. They cover a variety of topics from wastewater treatment methods to cleaner production strategies, as a careful management of water resources is the basis for sustainable development and to avoid potential security threats. The reader will benefit from a general view of some of the operations involved in wastewater treatment and solid concentration and disposal methods. A proper water reuse and recycling, together with efficient solid disposal, would contribute to a better use of the resources and a sustainable economic growth, particularly in many arid lands of the world.
