{"product_id":"biosorption-for-wastewater-contaminants-isbn-9781119737599","title":"Biosorption for Wastewater Contaminants","description":"\u003cp\u003ePollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a ­variety of environments, both urban and rural. \u003c\/p\u003e\u003cp\u003eThis book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. \u003c\/p\u003e\u003cp\u003e\u003ci\u003eBiosorption for Wastewater Contaminants\u003c\/i\u003e will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry. \u003c\/p\u003e\u003cp\u003eList of Contributors xii\u003c\/p\u003e \u003cp\u003ePreface xvi\u003c\/p\u003e \u003cp\u003eForeword xvii\u003c\/p\u003e \u003cp\u003e\u003cb\u003e1 Industrial Wastewater Contaminants and Their Hazardous Impacts \u003c\/b\u003e\u003cb\u003e1\u003c\/b\u003e\u003cbr\u003e \u003ci\u003eCamila Pesci Pereira, João Pedro Neves Goldenstein, and João Paulo Bassin\u003c\/i\u003e\u003c\/p\u003e \u003cp\u003eList of Abbreviations 1\u003c\/p\u003e \u003cp\u003eIntroduction 2\u003c\/p\u003e \u003cp\u003eToxic Heavy Metals 3\u003c\/p\u003e \u003cp\u003eDyes 5\u003c\/p\u003e \u003cp\u003eOil and Grease 8\u003c\/p\u003e \u003cp\u003eBiocides 10\u003c\/p\u003e \u003cp\u003eOrganic Compounds 12\u003c\/p\u003e \u003cp\u003eContaminants of Emerging Concern (CECs) 15\u003c\/p\u003e \u003cp\u003eConclusion 17\u003c\/p\u003e \u003cp\u003eReferences 19\u003c\/p\u003e \u003cp\u003e\u003cb\u003e2 Biosorption and Different Native Sources for Preparation of Biosorbents \u003c\/b\u003e\u003cb\u003e23\u003c\/b\u003e\u003cbr\u003e \u003ci\u003eA.B.

In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a ­variety of environments, both urban and rural.\u003c\/p\u003e \u003cp\u003eThis book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. \u003c\/p\u003e\u003cp\u003e\u003ci\u003eBiosorption for Wastewater Contaminants\u003c\/i\u003e will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.\u003c\/p\u003e","brand":"Wiley-Blackwell","offers":[{"title":"Default Title","offer_id":47988842135781,"sku":"NP9781119737599","price":231.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1842\/7735\/files\/9781119737599.jpg?v=1761781736","url":"https:\/\/k12savings.com\/es\/products\/biosorption-for-wastewater-contaminants-isbn-9781119737599","provider":"K12savings","version":"1.0","type":"link"}
