Book Description
The present work discusses two main environmental applications of biosorption and bioaccumulation processes. The first is environmental biomonitoring performed by living organisms. The property that is used here is that the level of a given contaminant in biological tissues is related to the concentration of this substance in the environment. This is expressed by the assessment of bioaccumulation factors. This book reports examples of the application of human hair and consumable tissues of animals, and various parts of plants (green parts as well as wood) in environmental pollution monitoring. Biosorption as well as bioaccumulation can find an application in removal of contaminants from aqueous solutions. Biosorption by different materials of plant (microalgal biomass, aquatic plants, plant leaves, straw, grass) and animal origin (eggshells, bones) can be applied in industrial wastewater treatment processes. Also, bioaccumulation by aquatic organisms: microalgae, macroalgae and aquatic plants in metal ions removal from effluents can be used to bind metal ions simultaneously with nutrients. An attempt to make the processes predictable is discussed here, including screening for good biosorbents/bioaccumulators, determining biosorption and bioaccumulation capacity as well as bioavailability as the function of the concentration of metals in the environment in which an organism is present, together with growth requirements, mathematical modelling, carrying out processes at different process conditions. This should constitute the basis for the assessment of standardized procedures, in the design of biosorption or bioaccumulation treatment plants and for environmental biomonitoring.

Book Description
This state-of-the-art volume represents the first comprehensively written book which focuses on the new field of biosorption. This fascinating work conveys essential fundamental information and outlines the perspectives of biosorption. It summarizes the metal-sorbing properties of nonliving bacterial, fungal, and algal biomass, plus highlights relevant metal-binding mechanisms. This volume also discusses the aspects of obtaining and processing microbial biomass and metal-chelating chemicals into industrially applicable biosorbent products. Microbiologists, chemists, and engineers with an interest in new technological and scientific horizons will find this reference indispensable.

Book Description
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.

Book Description
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.
