Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The new Canadian federal wastewater regulations, which restricts the release of ammonia from treated wastewaters, has resulted in upgrade initiatives at many water resource recovery facilities across the country to reduce the discharge of ammonia into our natural waters. The objective of this dissertation is therefore to investigate and optimize the performance of two attached growth technologies for rural and peri-urban/urban municipal ammonia removal. In particular, the first specific objective of this dissertation is to investigate the performance and microbial response of the BioCord technology as an upgrade system for the post-carbon removal nitrification of rural wastewaters. The second specific objective is to study the start-up of an attached growth anammox technology to enhance current knowledge pertaining to anammox biofilm attachment, growth and maturation. The results pertaining to the first specific objective of this research, a study of the design and optimization of the BioCord technology, demonstrates a recommended design rate for the post-carbon removal, nitrifying BioCord system of a surface area loading rate (SALR) of 1.6 NH4+-N/m2·d and up to 1.8 NH4+-N/m2·d with steady ammonia-nitrogen removal efficiencies greater than 90% and steady and low solids production rate up to 0.26 g TSS/d. A loss of system stability and biofilm sloughing, identified as fluctuating ammonia removal rates and solids production rates, were observed at elevated SALRs of 2.1 and 2.4 g -N/m2·d. The microbial results indicate that the meso-scale structure of the biofilm and the micro-animal population are directly affected by operational conditions. Enhanced air scouring configuration is shown to be a potential optimization strategy to prevent the clogging of biofilm pores and improve the system stability in terms of solids production rate in the BioCord technology. The results pertaining to the second specific objective of this research, the study of inoculation and carrier modification strategies for the rapid start-up of attached growth anammox technology, demonstrates significantly higher kinetics, faster biofilm growth and greater anammox bacteria enrichment on the silica-functionalized carriers and pre-seeded denitrifying carriers in a system inoculated with detached anammox biofilm mass during the early stages of attachment and growth of start-up. The study suggests that the use of the silica-functionalized and pre-seeded denitrifying carriers along with detached anammox biofilm inoculation has the potential to accelerate the anammox biofilm attachment, growth and maturation.
Book Synopsis A-B processes: Towards Energy Self-sufficient Municipal Wastewater Treatment by : Yu Liu
Download or read book A-B processes: Towards Energy Self-sufficient Municipal Wastewater Treatment written by Yu Liu and published by IWA Publishing. This book was released on 2019-11-15 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.
Book Synopsis Ammonia Removal in Wastewater with Anaerobic Ammonium Oxidation Process by : Tak Yin Chan
Download or read book Ammonia Removal in Wastewater with Anaerobic Ammonium Oxidation Process written by Tak Yin Chan and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentrated wastewaters produced in many agricultural and food industries are treated by anaerobic digestion nowadays. However, ammonium ion is not removed in the digestion process, thereby yielding an effluent containing a high concentration of ammonia and low biodegradable COD. This ammonium-rich effluent is usually treated by another wastewater treatment plant, but it is costly and troublesome. Recently, a novel process named Anammox (anaerobic ammonium oxidation) was discovered in which ammonium ion could be converted to nitrogen gas under anoxic conditions with nitrite as the electron acceptor. This innovative Anammox process, as a result, has made the nitrogen removal treatment more sustainable. Current modeling research with the combination of partial nitrification (Sharon) and Anammox reactors has been examined for the removal of ammonia from concentrated wastewater. It was evaluated that about 50% of ammonium ion was oxidized to nitrite in the Sharon process and more than 80% of the ammonia was converted into nitrogen gas in an Anammox reactor. This study aims at demonstrating the feasibility of ammonia removal by providing nitrite directly to the Anammox process without the preceding nitrification step. Results showed that approximately 60% of ammonium removal efficiency and 80% nitrite removal efficiency were achieved in a batch sequencing reactor. Additionally, more than 50% of COD removal was obtained, hence, successfully proving the potential of this method.

Download or read book System for Total Direct Recycle of Secondary Municipal Wastewater written by and published by . This book was released on 1975 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was performed leading to the design of a system to treat municipal secondary effluent to potable quality and allow closed-loop water utilization. A comprehensive literature survey resulted in the acquisition of other 800 papers and reports on all advanced wastewater treatment processes. Summary evaluations were prepared for the important processes. A definition of a set of potable water quality criteria parameters was developed for the specific case of closed-loop water reuse. Mathematical models for performance and costs were compiled for the individual processes. A computer program in Fortran was assembled incorporating the cost and performance models of the processes as subroutines. The resulting computer program represents a mathematical model of the conceptual system and can be used to perform design calculations of optional combinations of the processes.

Available in PDF, EPUB and Kindle. Book excerpt: In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.
