Anammox Technology In Industrial Wastewater Treatment

Ammonia in wastewater causes the eutrophication of water bodies and the subsequent depletion of dissolved oxygen. In addition, certain forms of nitrogen such as ammonia, nitrite, and nitrate are highly toxic to aquatic life. Although there are several biological and physical-chemical techniques for the removal of ammoniacal nitrogen compounds, including air stripping and breakpoint chlorination, which have been widely applied, a microbiological or microbe-based approach is attractive because it is based on sustainable technologies. In this regard, ammonia-oxidizing bacteria have recently gained great interest, specifically in wastewater treatment plants for the removal of ammoniacal nitrogen especially, owing to its relatively low capital cost, eco-friendliness, and high efficiency when compared with conventional cleanup technologies. This book provides specific and advanced knowledge on the microbial ecology of ammonia-oxidizing bacteria and their diversity and functions in the treatment of toxic pollutants present in wastewater. The book thus serves as a valuable resource for engineers, scientists, and managers who require an excellent introductory and advanced knowledge of the field, professionals who are working or interested in the environmental microbiology or bioremediation field, and students learning about environmental biotechnology and microbiology.

Unexplored Section of Biological Nitrogen Cycle in Industrial Wastewater Treatment - Anammox Process: Technological Advancement and Application in Industrial Wastewater Treatment Plant systematically summarizes up-to-date studies on the effect of various operational factors on nitrogen removal performance along with reactor type, mode of operation (batch or continuous), and cultured anammox bacterial species. The book lists the effect of potential anammox inhibition factors such as high nitrite concentration, high salinity, sulfides, toxic metal elements, and toxic organic compounds and provides a thorough interpretation of the synergistic and antagonistic toxicity of these inhibitors. It suggests the strategy for optimization of anammox processes for wastewater treatment, and stresses the importance of future studies on anammox applications.

Wastewater treatment management, alongside many other industries, is seeking to attain a higher degree of sustainability for its processes by focusing on new technologies which minimise the consumption of resources or even recover them from the wastewater. Conventional removal of ammonium requires usually large amounts of energy for aeration and organic carbon for denitrification. This report focuses on making the nitrogen-removal process more sustainable. This can be achieved by a partial oxidation of ammonium to nitrite, after which the nitrate produced can be converted into nitrogen gas with the rest of ammonium under anoxic conditions. The treatment of nitrogen-rich water can be carried out beneficially by a combination of the Sharon process with the Anammox process. In this combined process less than 50% of the aeration energy is needed, no COD is required and an insignificant amount of sludge is produced. In this Report the potential of using this technology for the treatment of water arising from sludge treatment at a municipal wastewater treatment plant (WWTP) is evaluated and the results of the operation of the system are described in detail. This reject water contains a significant fraction of the N-load towards the wastewater treatment plant. The results are used in an economic evaluation of a potential full scale installation. The Combined Sharon/Anammox Process Report will provide an invaluable source of information for all those concerned with the efficient and sustainable treatment of wastewater including plant managers, process designers, consultants and researchers.

Technical information for using activated sludge to treat effluents from multiple industries Covers virtually all traditional and advanced methods, as well as treatability and process modeling New methods for removing U.S. and European regulated microconstituents, trace organics, active pharmaceutical ingredients and other contaminants Explains advances in water reuse and plant retrofitting Useful for in-house training This comprehensive book presents critical information on the applications of activated sludge for treating industrial wastewaters, as well as other effluents that impact POTWs. The book offers details on how advances in activated sludge can be deployed to meet more stringent discharge limits by explaining many novel variations of activated sludge and offering technical guidance on process modeling and optimization. Special attention is given to emerging contaminants and water reuse strategies. Case studies are drawn from the pharma, food and shale gas industries. Based on short courses taught by the authors, as well as hundreds of hours of in-plant consulting, this book offers the tools to understand and modify the activated sludge process for superior and sustainable wastewater treatment. From the Authors' Preface: "After speaking with practitioners, operators and engineers, the authors felt a new text was needed...to cover the following developments: "the continued evolution of the activated sludge process and its numerous designs, configurations and technology developments; "design of industrial water reuse systems...to achieve industry sustainability goals; "changes...from BOD, TSS and nutrient removal to removal of specific organics, toxicity...microconstituents, and more stringent effluent permit limits; "advances in process modeling tools that can be used in combination with treatability testing tools for plant design, optimization and troubleshooting; "concerns over industrial wastewater discharge impacts to POTWs, such as nitrification inhibition, the impact of frac water...and the fate of microconstituents through POTWs."

The production of wastewater from various human and industrial activities has a harsh impact on the environment. Without adequate treatment, the disposal of this wastewater poses a threat to the quality of water globally. Technologies for the Treatment and Recovery of Nutrients from Industrial Wastewater investigates emergent research and best practices within the field of wastewater management. Highlighting novel technological tools in wastewater treatment, effective nutrient removal technologies, and innovative solutions to quality water preservation practices, this book is a critical reference source for professionals, scientists, academics, and students.

Current use of the ammonia oxidizing bacteria (AOB) within biological wastewater treatment system is incomplete due to limitations of current culture-based techniques. This book offers an overview of new nitrification technologies via the use of AOB in the removal of ammonia nitrogen from wastewater. The application of new approaches based on AOB leads to greater ammonia nitrogen removal and results in more efficient wastewater treatment.
