Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals always pose serious ecological risks when released into the environment due to their elemental non-degradable nature, regardless of their chemical form. This calls for the development of efficient and low-cost effluent treatment and metal recuperation technologies for contaminated waste water, not only because regulatory limits need to be met but also because the waste itself can be a resource for certain precious metals. Biosorption is a general property of living and dead biomass to rapidly bind and abiotically concentrate inorganic or organic compounds from even very diluted aqueous solutions. As a specific term, biosorption is a method that utilizes materials of biological origin – biosorbents formulated from non-living biomass - for the removal of target substances from aqueous solutions. Recent research on biosorption provides a solid understanding of the mechanism underlying microbial biosorption of heavy metals and related elements. This book gathers review articles analyzing current views on the mechanism and (bio)chemistry of biosorption, the performance of bacterial, fungal and algal biomass, and the practical aspects of biosorbent preparation and engineering. It also reviews the physico-chemical evaluations of biosorbents and modelling of the process as well as the importance of biosorption during heavy metal removal using living cells. It is a reference work for scientists, environmental safety engineers and R&D specialists who wish to further promote biosorption research and use the accumulated knowledge to develop and build industrial applications of biosorption in heavy metal separation technologies.

Book excerpt: Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.

Download or read book Biosorption for Wastewater Contaminants written by Pardeep Singh and published by John Wiley & Sons. This book was released on 2021-10-13 with total page 320 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Excessive and cumulative release of toxic metals from industrial effluents due to rapid industrialization has posed hazard to aquatic ecosystem integrity and environmental/ human health. The inadequacy and high cost of traditional metal treatment technologies coupled with the imposition of stricter environmental regulations and guidelines for industrial point source discharges have increased the demand for economically feasible alternative methods. Application of natural and abundant sorption material known as biosorbents comprising microbial biomass, agriculture waste, and industrial waste biomass, has gained international attention in scientific world as a low-cost and effective method for removal of heavy metals from aqueous solutions. However, this method has not been able to gain the attention of industry for large-scale applications thus far. This research was aimed to further evaluate the potential of biosorption technique in more realistic conditions appealing to industry by exploiting locally available biosorbents undergoing minimum pretreatment steps, combining living and non-living microbial biosorbents without any heat-inactivation, employing continuous-flow systems, and regenerating the used biomass for recovery of the mixture of heavy metals. The toxic metals of interest for biosorption in this work were copper, lead, and zinc, and biosorbents selected were cells of Saccharomyces cerevisiae as a microbial biomass and Acer saccharum tree leaves as an agro-waste. Sorption performances of the biosorbents were evaluated through classical adsorption equilibrium isotherms and kinetics in batch systems, and supplemented by dynamic continuous flow studies, which may serve as a basis for equipment sizing and scale up of the biosorption systems. Batch sorption studies revealed that pseudo-second order and Langmuir isotherm models were suitable to describe the metals sorption kinetics and equilibrium, respectively. Evaluation of biosorption performance and selection of best biosorbent using the Langmuir isotherm constants correctly were thoroughly discussed based on dynamic equilibrium between the metal species and biosorbents active sites. Design of experiment technique was used to determine model equations describing the removal efficiencies of mixture of the target metals by Saccharomyces cerevisiae with respect to operating conditions such as pH, metal concentration, and biomass dose. The selectivity order of Pb2+> Cu2+> Zn2+ was achieved by yeast cells with Pb2+ ions removal efficiencies reaching up to 98%. Process optimization helped to evaluate the simultaneous effects of pH, initial metal concentration, and biomass dose on competitive biosorption of metals by yeast cells. Characterization of metal-biomass interactions responsible for biosorption was studied employing zeta potential, BET, FT-IR, and SEM-EDX techniques. The results suggested the involvement of electrostatic interactions, ion exchange, interaparticle sequestration, and a weak surface binding in adsorption of the metals by the selected biosorbents. The use of unmodified yeast cells in a self-contained continuous system was shown to be an effective metal biosorption method by minimizing biomass pretreatment and preparation steps as well as achieving an on-line and concurrent biosorbent production and metal biosorption within the same system. Biosorptive performance of maple leaves in multiple column sorption-desorption cycles showed no degradation on metal capacity of the biomass (18.3 mg Cu/g) with increasing cycles despite shortening breakthrough times. Biomass regeneration efficiencies up to 98% were achieved using a weak acid as eluent. The presented simplified mass transfer model based on rapid local equilibrium and an apparent dispersion coefficient well simulated the dynamic operation of the packed bed biosorption column. Research conducted in this thesis can be of value to industries searching for efficient, simple, and green alternative metal treatment methods to meet the regulatory limits for the heavy metals discharges at a lower cost.

Available in PDF, EPUB and Kindle. Book excerpt: Multidisciplinary resource for graduate studies and the biotechnology industry Knowledge of the genetic basis of biological functioning continues to grow at an astronomical rate, as do the challenges and opportunities of applying this information to the production of therapeutic compounds, specialty biochemicals, functional food ingredients, environmentally friendly biocatalysts, and new bioproducts from renewable resources. While genetic engineering of living organisms transforms the science of genomics into treatments for cancer, diabetes, and heart disease, or products for industry and agriculture, the science and technology of bioseparations are the keys to delivering these products in a purified form suitable for use by people. The methods, theory, and materials that reduce the science of bioseparations to practice, whether in the laboratory or the plant, are the subjects of Bioseparations Engineering. Examples address purification of biomolecules ranging from recombinant proteins to gene therapy products, with footnotes detailing economics of the products. Mechanistic analysis and engineering design methods are given for: \* Isocratic and gradient chromatography \* Sedimentation, centrifugation, and filtration \* Membrane systems \* Precipitation and crystallization Topics addressed within this framework are: stationary phase selection; separations development; modeling of ion exchange, size exclusion, reversed phase, hydrophobic interaction, and affinity chromatography; the impact of regulatory issues on chromatography process design; organization of separation strategies into logical sequences of purification steps; and bridges between molecular biology, combinatorial methods, and separations science. A result of teaching and developing the subject matter over ten years, Bioseparations Engineering is an ideal text for graduate students, as well as a timely desk book for process engineers, process scientists, researchers, and research associates in the pharmaceutical, food, and life sciences industries.

This book was released on 2014-05-13 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is based on research work and several literature. Heavy metals, especially Nickel and Chromium can have serious effects on human and animal health and they are non-renewable resources. Therefore effective recovery of heavy metals is as important as removal of them from waste streams.The conventional methods may be ineffective or expensive, especially when the heavy metal ions are in solutions containing in the order of 1-100 mg dissolved heavy metal ions/L.The Calotropis procera and Embalica officinalis, plant biomasses were investigated as a new biosorbent for the removal of Ni(II) and Cr(VI) from aqueous solution with 90% and 100% sorption efficiency of Ni(II) and Cr(VI) from 50 mg/L solution. This study provides information on the removal of Cr(VI) and Ni(II) by using two different low cost adsorbents. Different parameters, adsorption isotherm and elution test, co-ions effects etc were studied.
