DOWNLOAD EBOOKWhilst heavy metal phytotoxicity has been known for more than a century, it is astonishing that interest in the effects of heavy metals on organisms has only recently received added attention. Research in the past years, however, has confirmed the immense damage by metal pollution to plants, the soil and ultimately to humans. This completely updated and enlarged second edition gives a state-of-the art review on both field and laboratory work. It deals with the various functional and ecological aspects of heavy metal stress on plants and outlines the scope for future research and the possibilities for remediation.

DOWNLOAD EBOOKCurrent Developments in Biotechnology and Bioengineering: Solid Waste Management provides extensive coverage of new developments, state-of-the-art technologies, and potential future trends, reviewing the latest innovative developments in environmental biotechnology and bioengineering as they pertain to solid wastes, also revealing current research priority areas in solid waste treatment and management. The fate of solid wastes can be divided into three major areas, recycling, energy recovery, and safe disposal. From this foundation, the book covers such key areas as biotechnological production of value added products from solid waste, bioenergy production from various organic solid wastes, and biotechnological solutions for safe, environmentally-friendly treatment and disposal. The state of the art situation, potential advantages, and limitations are discussed, along with proposed strategies on how to overcome limitations. - Reviews available bioprocesses for the production of bioproducts from solid waste - Outlines processes for the production of energy from solid waste using biochemical conversion processes - Lists various environmentally friendly treatments of solid waste and its safe disposal

DOWNLOAD EBOOKResource Recovery in Industrial Waste Waters provides a holistic approach for discovering and harnessing valuable resources from industrial wastewaters, the cutting-edge technologies required, and a discussion on the new findings. In three volumes, the books stress the importance of contaminated waters' remediation, including surface waters, municipal or industrial wastewaters and treating these waters as a new source of nutrients, minerals and energy. It introduces polluted waters as new and sustainable sources, rather than seeing wastewaters as only a source of hazardous organic and inorganic matters. Sections discuss wastewater treatment and recovery and contribute to generate a sustainable approach of wastewater by providing the main advantages and disadvantages of both wastewater/polluted water treatment and recovery. - Reviews the current status of industrial wastewater treatment methods - Discusses the growing need of resource recovery from industrial wastewater, along with the challenges - Describes the importance of water reuse for combating water scarcity by describing current techniques and challenges - Evaluates the potential of the current market and status towards industrial wastewater resource recovery - Considers cutting-edge technologies for resource recovery - Contains comprehensive discussions on possibility of almost all recoverable resources from industrial wastewater

DOWNLOAD EBOOKSustainable and Circular Management of Resources and Waste Towards a Green Deal highlights the importance of resource recovery, phosphorus management, climate action, clean energy transition, and a circular economy. The world is facing significant challenges, including climate disruption, environmental changes, pollution, and population explosion. Sustainable management of finite natural resources within the carrying capacity of the bio-geo-hydrosphere is the crux of transforming the global economy for a sustainable future. Moreover, keeping raw materials in circulation as long as possible and minimizing the amount of waste generated has grown in significance as a part of transitioning to a circular economy (CE) model. - Introduces innovative solutions in green energy transition - Provides case studies as examples of a circular economy implementation in selected sectors of the economy, including water and wastewater, raw materials, and construction - Suggests actions to counteract climate change and its consequences for people and the planet

DOWNLOAD EBOOKZinc and copper are supplemented into a swine's diet in relatively large concentrations and then further concentrated in sludge by anaerobic digestion. Anaerobic digestion, which produces energy and organic fertilizer, is gaining popularity as a treatment of swine manure. Land application can be used for disposal, although these sludges can contaminate the soil with heavy metals. The concentrations of zinc and copper in anaerobically digested swine manure are approximately 2,900 mg/kg and 1200 mg/kg respectively. These concentrations greatly exceed the regulations for many European countries and are on the borderline for the EPA 503 land application limits. Metals when released into the environment can accumulate to high concentrations and can contaminate soils, groundwater and living organisms. Bioleaching is a process that removes metals from solids or biomass, by acidifying the sludge and therefore solubilizing the metals attached to biosolids. Bioleaching has been successfully applied to many other waste streams but has yet to be applied to anaerobically digested swine manure, which contains both high ammonia and organic compounds both are toxic to sulfur oxidizing bacteria. Traditional physical and chemical methods for metal removal are expensive. Removal of heavy metals by bioleaching has the potential to be highly efficient and economical. A Thiobacilli culture was established by acclimating the bacteria to anaerobically digested swine manure using elemental sulfur. The bioleaching batch tests used this inoculum in the bioleaching experiments. Experiments were completed to test the effects of inoculation, substrate, and solids concentration. ORP, pH, sulfate, nitrate, pathogen reduction, copper and zinc were measured regularly in this study. Results showed that bioleaching is feasible to remove copper and zinc from anaerobically digested swine manure. Inoculation proved to be valuable in increasing the rate of acidification. The results also showed that at high concentrations above 6% TS, the potential for using bioleaching decreases and that higher sulfur concentration yield greater metal removal efficiencies. Using 6% TS and 10,000 mg/l of elemental sulfur in the batch experiments, 94% of Zn and 72% of Cu was solubilized.

DOWNLOAD EBOOKSelected Proceedings of the 1st IWA World Water Congress, held in Paris, France, 3-7 July 2000. The World Water Congress held in Paris in July 2000 was the first under the banner of the International Water Association, formed by the merger of the International Association on Water Quality and the International Water Services Association. The success of the merger was reflected in the unprecedented degree of interest and participation in the Congress, with nearly two-and-a-half thousand delegates attending for 450 oral presentations, 750 poster presentations and 4 workshops and seminars. From the large number of oral presentations, 46 have been selected for this issue, dealing with aspects of: Hazard assessment and control of environmental contaminants, including endocrine disrupting substances; chemical industries and pulp and paper industries wastewaters Pretreatment of industrial wastewater With authors who rank among the world's leading experts in these fields, tackling some of the most prominent contemporary problems, these proceedings are an essential compilation of the latest advances relating to industrial wastewaters and environmental contamination.

DOWNLOAD EBOOKTraditional reliance on chemical analysis to understand the direction and extent of treatment in a bioremediation process has been found to be inadequate. Whereas the goal of bioremediation is toxicity reduction, few direct, reliable measures of this process are as yet available. Another area of intense discussion is the assessment of market forces contributing to the acceptability of bioremediation. Finally, another important component is a series of lectures and lively exchanges devoted to practical applications of different bioremediation technologies. The range of subjects covers a wide spectrum, encompassing emerging technologies as well as actual, full-scale operations. Examples discussed include landfarming, biopiling, composting, phytoremediation and mycoremediation. Each technology is explored for its utility and capability to provide desired treatment goals. Advantages and limitations of each technology are discussed. The concept of natural attenuation is also critically evaluated since in some cases where time to remediation is not a significant factor, it may be an alternative to active bioremediation operations.
