This book was released on 2012-01-10 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides public health, sanitary and water engineers baseline data for designing plants for the treatment of industrial effluents rich in the metallic species in general and that of nickel and chromium in particular. DescriptionWater pollution is a topic of immense and common concern throughout the world. With a rapidly escalating global population and increased industrial development in a growing number of countries, the world's freshwater resources have become stressed. One way to get more out of less is 'treatment and reuse'. Nickel and chromium are toxic metals and they are used extensively in numerous industries such as textiles, beverages, steel, pulp and paper, and electroplating. Their industrial effluent contains large measures of non-biodegradable traces that are harmful to flora, fauna, and human beings. Although there are a number of methodologies used for treatment of metal-containing industrial effluents and waste water, there is not one up to now that offers a high capacity removal rate at an economical cost. This book presents the results and data from research and adsorption experiments carried out on the removal of nickel and chromium (as well as other metals) from aqueous solutions using modified silica sand. The data resulting from detailed kinetic, equilibrium and thermodynamic studies, show that the removal capacity is increased so the treated water has a higher quality or purity. It also demonstrates that the extraction of metals is achieved at a significant lower cost because the treated water adsorption is a simple process with less maintenance, and because silica is a nontoxic natural material widely available in all parts of the world.

This book was released on 2005-03-11 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Available in PDF, EPUB and Kindle. Book excerpt: Pollution 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. This 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. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.

This book was released on 2014-11-25 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals represent an important source of environmental pollution. Oil and petrochemical industries produce considerable amounts of heavy metals that finds its way to water sources such as rivers, lakes, sea, and ground water in addition to soil . Biological treatment units are unable to remove these metals since they are non-biodegradable. Considerable attention had been given for the treatment of heavy metals in recent years. North oil refineries company in Baiji suffer from the presence of many heavy metals in the discharged wastewater from biological treatment unit. The concentration of many of these heavy metals concentrations exceed the allowable concentrations according to the Iraqi limits. The present work is a trial to treat Copper, Manganeze, and Zinc from a synthetic wastewater using activated carbon. The study proved that these metals can be removed completely. However the breakthrough and exhaustion times for Zinc are lower than that of Copper and Manganese. The study proved also that adsorption capacity is not a pure property of activated carbon, but it depends on the operating conditions and the type of adsorbent and adsorbate and their characteristics.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effluents from essential industries have been characterized with heavy metals which are non-biodegradable in nature and also detrimental to health when accumulated in body tissues over long exposure. Adsorption was proved as the best efficient process amongst others to remove these heavy metals from industrial wastewater due to its excellent features. Activated carbons from nanoparticles of agricultural wastes such as pods, shells, husks, peels, shafts and many prepared via calcination process at high temperature can be used as active adsorbent for the industrial wastewater treatment involving heavy metals removal. This chapter discusses heavy metals in industrial wastewater effluents and potential agro wastes from which nanoparticles of activated carbon for industrial wastewater purification could be generated. The transformation of agro wastes nanoparticles into activated carbons via calcination and their applications for heavy metals removal from industrial wastewater via adsorption were examined. Various characterization techniques to study the effects of calcination on structural, morphological and textural properties of activated carbon prepared from agro waste nanoparticles were also discussed. Various isotherm, kinetics, mechanistic and thermodynamics models to investigate the adsorptive nature of the process were presented. Error functions and algorithms for both the linear and non-linear isotherm models regression to affirm their fitness for prediction were presented. Lastly, proposed adsorption mechanisms of heavy metals removal from industrial wastewater using activated carbons from nanoparticles of agro wastes were presented.

Book excerpt: In this Book, The utilization of agricultural waste to produce valuable products has been investigated to minimize serious public health risks from exposure to dangerous fumes that come from burning the agricultural wastes in open fields. In this study, activated carbon produced from cotton stalks was examined for the removal of target heavy metal contaminants from water and wastewater. Adsorption studies conducted in completely mixed batch reactors and continuous flow columns showed a good affinity of the produced activated carbon to remove heavy metals, namely lead, cadmium and copper from aqueous solutions compared to other commercial adsorbents. The highest adsorption capacity was for lead, followed by copper and then cadmium. Multicomponent metal adsorption experiments indicated a competition for the available surface sites. Adsorption capacities in the mixture were reduced from their single-solute values for all metals.

Available in PDF, EPUB and Kindle. Book excerpt: Adsorption processes are extensively used in wastewater treatment for heavy metal removal. The most widely used adsorbent is activated carbon giving the best of results but it,Äôs high cost limits its use. It has a high cost of production and regeneration. As the world today faces a shortage of freshwater resources, it is inevitable to look for alternatives that lessen the burden on existing resources. Also, heavy metals are toxic even in trace concentrations, so an environmentally safe method of their removal necessitated the requirement of low cost adsorbents. Adsorption is a cost-effective technique and gained recognition due to its minimum waste disposal advantage. This chapter focuses on the process of adsorption and the types of adsorbent available today. It also encompasses the low-cost adsorbents ranging from agricultural waste to industrial waste explaining the adsorption reaction condition. The cost-effectiveness, technical applicability and easy availability of raw material with low negative impact on the system are the precursors in selecting the adsorbents. The novelty of the chapter lies in covering a wide range of adsorbents with their efficiency in removal of heavy metals from wastewater.
