This book was released on 2010-03-10 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution—air, water, soil, and noise. 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 continues to exist, 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 identi?ed: (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? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution problems has been a major contributing factor to the success of environmental en- neering, and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

Download or read book Advanced and Innovative Approaches of Environmental Biotechnology in Industrial Wastewater Treatment written by Maulin P. Shah and published by Springer Nature. This book was released on 2023-07-31 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses new and innovative trends and techniques in the removal of toxic and refractory pollutants by means of various microbial biotechnology processes from wastewater, both on the laboratory and industrial scales. The book also highlights the main factors contributing to the removal of toxic pollutants as well as recycling, environmental impact, and wastewater policies after heavy metal removal. In addition, it assesses the potential application of several existing bioremediation techniques and introduces new cutting-edge emerging technologies. This book significantly contributes to the wastewater treatment plant industry so that the treatment systems can serve better and more resiliently for the purpose. This book is designed for engineers, scientists, and other professionals who are seeking introductory knowledge of the principles of environmental bioremediation technology and for students who are interested in the environmental microbiology and bioremediation fields.

Available in PDF, EPUB and Kindle. Book excerpt: "More than two-thirds of the earth is covered with aquatic habitats that play a key role in stabilizing the global environment and providing a wide variety of services to increasing human needs. Nevertheless, anthropogenic activities are rapidly destroying the quality of both fresh and marine waters over the globe due to excessive use of chemicals and fertilizers, and pollution from suburban and industrial areas eventually make their way into the aquatic world. To preserve the integrity of aquatic environs is the greatest challenge in the current era because more than 80 per cent of urban wastewater, millions of tons of heavy metals chemical, toxic sludge and other waste are being directly discharged into inland waters. There are many reports that bacteria and plant species are using biodegradation and bioremediation strategies. The potential drivers of the commercial use of biological resources are yet to be explored as there are issues involved with technological facilitation and it's need for large investment funds, so there is a need to explore better training and development of more eco-friendly biological resources. After global investigation, the use of biological remediation technologies to deal with environmental problems should become standard practice, even though respondents are striving to apply bioremediation techniques. As microorganisms have evolved different survival strategies in heavier metal-polluted conditions such as biosorption, bioaccumulation or biomineralisation, which are either ex situ or in situ exploitation, these organisms are known to evolve and introduce specific detoxification mechanisms. The use of microbes as a time-saver for bioremediation was a result of the complexities involved in conventional soil regeneration methods. There are so many fungal species (like genera Penicillium, Aspergillus and Rhizopus) which has been identified as potential microbial agents for the removal of heavy metals from aqueous solutions but due to toxicity of chemical or heavy metals, it is difficult to maintain a healthy population of microorganisms hence high throughput genetic engineering tools and techniques need to be employed to attain resistant strains to degrade xenobiotic compounds. A novel technology for obtaining highly efficient biosorbents from endophytes, a hyperaccumulator, which is more convenient than the traditional method of obtaining biosorbents. Genomics, for instance in GMO plants, have been studied and used primarily in microbial genetics, but it is now a new instrument for bioremediation. Knowledge of genomics in the sense of understanding microbiological remediation provides a view of genes linked to microbial exposure to soil toxic metals. The use of genomics in bioremediation enables microorganisms to be analyzed on the basis both of biochemical and mechanism-related molecular levels."--

This book was released on 1998-05-06 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents information that can be used for the design and operation of wastewater treatment plants that utilize biological nutrient removal processes, i.e., processes that utilize biological mechanisms instead of chemical mechanisms, to remove phosphorus and nitrogen from wastewaters. The book provides: basic fundamentals, concepts, and theories; design of prefermentation units, various types of BNR systems, and secondary clarifiers; retrofitting conventional activated sludge plants; modeling considerations; and special considerations for BNR systems. It includes full-scale and pilot plant case histories, design examples, and retrofit of existing plants.
