Download or read book Nitrification in Fixed Bed Reactors Treating Saline Wastewater written by Sudarno and published by KIT Scientific Publishing. This book was released on 2014-08-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two fixed bed reactors for nitrification with either polyethylene/clay sinter lamellas (FBR A) or porous ceramic rings (FBR B) were continously run for treating synthetic saline wastewater. Seawater from Hafen Büsum was used as an inoculums. The performance of the system was evaluated under different operating conditions.A better overall nitrification without nitrite accumulation was observed in FBR B during continuous incubation. However, in term of ammonia (AOR) and nitrite oxidation rates (NOR) that were determined in batch incubations, FBR A revealed a higher AOR and NOR of 6 and 7 mg N L-1 h-1, compared to the AOR and NOR of 5 and 5.9 mg N L-1 h-1 in FBR B, respectively.For studies of the effect of fluctuating salinity on the nitrification, polyethylene/clay sinter lamellas or porous ceramic rings from FBR A and B, respectively, were used as a source of immobilized nitrifiers. Salt concentrations were decreased from 3.5% to 0.03% via 2, 1 and 0.5% and increased from 3.5% to 5, 7 and 9%.A similar result for AOR and NOR during batch incubation was obtained for both substrata in FBR A and FBR B. The salinity changes influenced more the nitrite oxidizing bacteria (NOB) than the ammonia oxidizing bacteria (AOB).Measurement of oxidation rates during changing conditions show that the NORs were always higher than the AORs in all reactors, especially in initial phase. However, NORs were more sensitive to the salinity fluctuation than AORs, especially at lower salinity. The AORs remained constant for 0.5-3.5% NaCl and dropped to 70% and 68.5% after the salt concentration was brought to 0.034 or 5%, respectively. The NORs decreased significantly to 62% and 87.5% of initial rates after the salt concentration was changed to 2 and 5%, respectively.Non-halotolerant nitrifiers reactors with fresh polyethylene/clay as supporting material were inoculated with water samples taken from a "Brackwasser"-location at the North Sea and were continuously run. The salt content in medium

Download or read book General Management in Latin and Ibero American Organizations written by Adrián A. Caldart and published by Routledge. This book was released on 2019-06-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an examination of the general manager, which encompasses their roles as strategist, organizational designer and institutional leader. Instead of exclusively focusing on the economic aspect of general management, this book explores a humanist perspective based on the conviction that maintaining high ethical standards is a precondition to the healthy, long-term prosperity of firms and, more importantly, the development of employees. Bringing together a team of contributors from several prestigious business schools in Spain, Portugal, and Central and South America, this book develops the field of general management through academic thinking, research and practical experience in the form of original and relevant case studies from the perspective of Ibero-American business communities. After explaining the foundations of its call for humanist general management practices, the authors focus on themes inherent to strategy and organizing such as sustainability, business model innovation, strategy in emerging markets, strategic alliances, digital strategy and organizational learning. They conclude by focusing on institutional leadership, and provide a fresh look at boards of directors, risk management, family businesses, stakeholder management and the work of CEOs. General Management in Latin and Ibero-American Organizations is an invaluable resource that will be of great interest to practitioners and students in the field of international business, management, organization studies, strategy in emerging markets, leadership and corporate governance.

This book was released on 2020-05-08 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the prospects of fresh market waste management in developing countries. It characterizes fresh market wastewater and solid wastes, and highlights the human health impact of corresponding waste management practices. With regard to treatment technologies, the book discusses the anaerobic digestion of fresh solid wastes; the application of natural coagulants for wastewater treatment; the remediation of xenobiotics in wastewater using nanotechnology; and biofilter aquaponic systems for nutrient removal. All of these technologies are recent innovations, offer several concrete advantages, and can be applied in developing countries as non-central treatment systems. In addition, the book covers electricity production from fresh solid wastes using microbial fuel cells, demonstrating the potential held by recycling fresh market wastewater and solid wastes.

Download or read book Fixed film Reactors In Wastewater Treatment written by Nicholas F Gray and published by World Scientific. This book was released on 2020-08-17 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our rivers and lakes are continuously self-purifying thanks to algal and bacterial biofilms that grow over the surface of stones and other debris. This same process has been employed for over a century to treat our municipal and industrial wastewater in specially designed fixed film reactors that maximize this microbial activity by providing ideal growth conditions and unlimited food and oxygen. Fixed film, or attached biofilm, reactors are unique in their ability to treat complex wastewaters and shock loadings; using far less energy than other wastewater treatment processes such as activated sludge, making them a sustainable treatment option.Targeted at undergraduate and postgraduate engineers and scientists, this book follows the structure of bestseller Biology of Wastewater Treatment. This volume gives an expanded and up-to-date overview of the use of fixed-film reactors in wastewater treatment with content spanning from biofilm formation, to traditional trickling filters and rotating biological contactor technology, advanced submerged systems (including MBBRs and IFAS) and their key role in the treatment of contaminated air, and finally to nitrogen removal employing new microbial pathways such as Anammox. This monograph emphasizes the biological aspects of the processes.

Download or read book Removal of Emerging Contaminants Through Microbial Processes written by Maulin P Shah and published by Springer Nature. This book was released on 2020-10-14 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of organic pollutants found in wastewater affect urban surface waters. Traditional wastewater management technologies focus on the removal of suspended solids, nutrients and bacteria, however, new pollutants such as synthetic or naturally occurring chemicals are often not monitored in the environment despite having the potential to enter the environment and cause adverse ecological and human health effects. Collectively referred to as "emerging contaminants," they are mostly derived from domestic activities and occur in trace concentrations ranging from pico to micrograms per liter. Environmental contaminants are resistant to conventional wastewater treatment processes and most of them remain unaffected, causing contamination of receiving water. This in turn leads to the need for advanced wastewater treatment processes capable of removing environmental contaminants to ensure safe fresh water sources. This book provides an up-to-date overview of the current bioremediation strategies, including their limitations, challenges and their potential application to remove environmental pollutants. It also introduces the latest trends and advances in environmental bioremediation, and presents the state-of-the-art in biological and chemical wastewater treatment processes. As such, it will appeal to researchers and policy-makers, as well as undergraduate and graduate environmental sciences students.
