Book Description :

Current wastewater treatment technologies are not sustainable simply due to their high operational costs and process inefficiency. Integrated Microbial Fuel Cells for Wastewater Treatment is intended for professionals who are searching for an innovative method to improve the efficiencies of wastewater treatment processes by exploiting the potential of Microbial Fuel Cells (MFCs) technology. The book is broadly divided into four sections. It begins with an overview of the "state of the art" bioelectrochemical systems (BESs) as well as the fundamentals of MFC technology and its potential to enhance wastewater treatment efficiencies and reduce electricity generation cost. In section two, discusses the integration, installation, and optimization of MFC into conventional wastewater treatment processes such as activated sludge process, lagoons, constructed wetlands, and membrane bioreactors. Section three outlines integrations of MFCs into other wastewater processes. The final section provides explorative studies of MFC integrated systems for large scale wastewater treatment and the challenges which are inherent in the upscaling process. Clearly describes the latest techniques for integrating MFC into traditional wastewater treatment processes such as activated sludge process, lagoons, constructed wetlands, and membrane bioreactors Discusses the fundamentals of bioelectrochemical systems for degrading the contaminants from the municipal and industrial wastewater Covers methods for the optimization of integrated systems

Book Description :

The simultaneous treatment of wastewater and generation of electricity using single-chamber, two-chamber, and stacked-cell microbial fuel cell configurations are well-documented in the literature. Recently, several studies have demonstrated the possibility of integrating microbial fuel cells into existing wastewater treatment configurations (e.g. sequencing batch reactors and membrane systems) for simultaneous removal of carbonaceous and nitrogenous pollutants and electricity production from wastewater. Rotating biological contactors are important biofilm processes used for organic carbon removal and nitrification that microbial fuel cells could be integrated into. The objective of this study was to test the possibility of integrating microbial fuel cells into rotating biological contactor systems for COD removal and nitrification and electricity generation from wastewater. To achieve this objective, two three-stage rotating biological contactor units (RBC and RBC-MFC) were constructed. The RBC-MFC was operated in a closed-circuit mode while the RBC was used as a control (open circuit). The anode was made of carbon fiber brush that extended along the bottom of each stage. Each stage had a horizontal graphite shaft on which eight carbon felt cathode discs were mounted. Six experimental runs were conducted to test the effect of the hydraulic loading rate, COD/N ratio and step-feeding conditions on organic carbon and ammonia removal on both units. Although the system needs to be optimized to generate higher voltage outputs and current densities, this study showed the possibility of integrating microbial fuel cells into rotating biological contactor systems with efficient removal of both COD and ammonia.

Book Description :

Proper treatment of wastewater is important to human health and societal development, and the commonly applied wastewater treatment technologies based on aerobic treatment have a significant demand for energy. Thus, new treatment technologies with low energy consumption and possible recovery of valuable resources (e.g., energy and water) from wastewater become of strong interest. Among the newly developed concepts, microbial fuel cells (MFCs) integrated with constructed wetland appear to be very attractive because of direct electricity generation from organic compounds and treatment of wastewater. Constructed wetland coupled with microbial fuel cell (CW-MFC) is an emerging technology in recent years and has attracted a lot of attention from researchers in the fields of wastewater treatment and bioenergy production. CW-MFC is a promising technology in the fields of wastewater treatment and bioenergy. However, at current power levels, the advantage of combining the two is mainly because of the enhancement of wastewater treatment in anaerobic zones within the wetland. New operational strategies need to be explored to increase and utilize electricity output.

Book Description :

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.

Book Description :

A hybrid system was developed by integrating MFC into CW for enhanced wastewater treatment and bioelectricity generation. The research is divided into five major scopes. The first scope is about design and fabrication of CW-MFC reactor, where electrodes are embedded into CW and feasibility of such hybrid system was tested for simultaneous organic and nutrient-containing wastewater treatment and bioelectricity production. Evaluation on denitrification, nitrification and organic matter removal efficiency corroborate wastewater treatment capabilities, and bioelectricity production performance were carried out. The performance of CW-MFC was compared with previous literature on CW reactor of similar dimension, design and configuration to corroborate the effectiveness of the hybrid system. The second scope of the research mainly focuses on the investigation of the effect of electrode spacing, the effect of organic loading rates, the effect of circuit connection on the performance of organic pollutant removal and electricity generation. The overall performance between the closed circuit and open circuit system were compared and put into perspective. The morphology of granular activated carbon electrodes was observed by using a scanning electron microscope (SEM).

Book Description :

A Microbial Fuel Cell (MFC) is a device used to harvest electrons from living microorganisms to generate electrical power. After decades of development, new architectures have been developed and new materials have been applied to MFC systems. Improvements to this promising technology have been extensively reported. However, scientists and engineers are still facing difficulties on enhancing energy output and increasing the MFC system efficiencies. In addition to physical resistances caused by MFC materials, there are still many unknown factors affecting the electron transfer pathway used by microorganisms in MFC environments. To increase the performance, a series of technologies have been integrated into MFCs. For instance, MFC technology has been combined with other technologies such as algae pounds, anaerobic digesters and constructed wetlands, to increase substrate utilization efficiency. As one example, CW-MFCs have already been studied for wastewater treatment and electricity generation. However, the system efficiencies presented by current models are low, and new designs need be explored to reduce the energy cost during installation and operation of CW-MFC systems. The first objective of this thesis research was to review the development of MFCs and relevant technologies, then to evaluate the energy loses and efficiencies in MFC systems, leading to a comprehensive understanding of MFC system from a thermodynamic viewpoint. The second objective was to design and construct a down-flow Constructed Wetland-Microbial Fuel Cell combined system with a semi-air cathode and analyze its performance. This innovative design will be able to enhance the system efficiencies of CW-MFCs by reducing external energy requirements, and this research will provide foundational work for further CW-MFC explorations

Book Description :

The objective of this doctorate research is to explore BES application in high energy consumption wastewater treatment and substrate recovery processes--metal removal, nitrogen removal and desalination to relieve the cost of electricity in these processes and take maximum advantage of limited power generated from BES to build self-sustainable treatment systems. Firstly, a self-sustained hybrid BES consisting of microbial fuel cell (MFC) and microbial electrolysis cell (MEC) was developed to reduce multiple metals simultaneously by utilizing different reaction potentials. Three heavy metals representing spontaneous reaction (chromium, Cr) and unspontaneous reaction (lead, Pb and nickel, Ni) were selected in this batch-mode study. Secondly, an integrated short-cut nitrification and autotrophic denitrification microbial fuel cell (SNAD-MFC) was developed to achieve energy-positive nitrogen removal from wastewater to save the energy consumption and chemical input in traditional biological nitrogen removal process. Thirdly, BES was applied in the anammox process where slow growth rate of anammox bacteria was the imminent problem for system efficiency and stability. This innovative solution was explored in this study by accelerating anammox in microbial electrolysis cells (MECs) and alleviating the dependence on anammox bacteria. Finally, self-sustained hybrid system utilizing the energy produced from microbial desalination cell (MDC) was studied by integrating MDC and MEC to simultaneously remove nitrogen in wastewater and metal ions in industrial wastewater and desalinate saline water. Integrated MDC-MEC could realize the maximum utilization of BES energy and synchronous treatment of different kinds of wastewater.

Book Description :

Efforts to remove and recover nutrients from wastewater are motivated by the United Nations Sustainable Development Goals and the National Academy of Engineering Grand Challenges of Engineering. Of the seventeen Sustainable Development Goals (SDGs), multiple SDGs relate to managing nutrients in wastewater. SDG 6, which is to “ensure availability and sustainable management of water and sanitation for all,” contains targets that aim to improve water quality by reducing pollution, halve the amount of untreated wastewater released to the environment, and increase recycling and safe reuse of wastewater (UN, 2017). SDG 2 seeks to improve food security and SDG 12 seeks to sustainably manage natural resources. Similarly, the National Academy of Engineering Grand Challenges of Engineering highlight managing the nitrogen cycle and providing access to clean water (NAE, 2019). Centralized wastewater treatment plants (WWTPs) have historically been designed to remove nutrients (such as nitrogen and phosphorus) and other contaminants prior to discharge. Modern wastewater treatment practices integrate recovery of resources including nutrients, energy, and water. The many available technologies, coupled with competing priorities, can complicate community decision-making on the choice of technology and the scale at which to implement the technology (i.e. building, community, or city), as well as determining how new upstream treatment may affect existing downstream treatment. Technologies that recover energy or manage nutrients such as anaerobic digestion, struvite precipitation, and microbial fuel cells can be implemented at a variety of scales in urban settings and may also be viable for influent types such as agricultural waste. Therefore, the overall goal of this dissertation is to contribute to the achievement of multiple sustainable development goals through the removal and recovery of nitrogen and phosphorus from a variety of influents at a variety of scales. One type of decision-making tool that assists in the choice of nutrient management technologies is a House of Quality. I developed a tool based on the House of Quality that integrated multiple priorities at three scales in a sewershed and produced rankings that generally align with current wastewater treatment practice. Accordingly, top-ranked city-scale technologies are those commonly employed (e.g. A2O, oxidation ditch) that use the dissolved organic carbon present in the wastewater to drive denitrification. Similarly, conventional treatment (e.g. flush toilet connected to a sewer) is ranked highest at the building scale because of its easy maintenance, small footprint, and inoffensive aesthetics. However, future trends such as technology development will likely affect the technologies, weightings, and scores and therefore improve the ranking of novel and emerging technologies. This trend may be amplified by the implementation of test beds, which can provide opportunities to improve the technical characteristics of developing technologies while minimizing risk for municipalities. The House of Quality planning tool was utilized in an in silico case study to analyze nutrient management technologies at three scales across the Northwest Regional Water Reclamation Facility sewershed in Hillsborough County, FL. The study demonstrated that employing treatment technologies upstream from the centralized wastewater treatment (i.e. building-scale source separation and community-scale technologies) could reduce nitrogen loading to the mainstream treatment train by over 50%. Sidestream treatment (i.e. the liquid effluent of anaerobic digestion that typically recycles back to the beginning of the mainstream treatment process) has minimal impact in nitrogen reduction, but is effective in reducing phosphorus loading to the mainstream due to high quantities of phosphorus recycling back to the head of the plant. These results can inform decision-makers about which context-specific nutrient management technologies to consider at a variety of scales, and illustrate that sidestream technologies can be the most effective in reducing phosphorus loading while building- and community-scale technologies can be most effective in reducing nitrogen loading to the centralized treatment plant. Struvite precipitation and microbial fuel cells (MFCs) can be used in combination to manage nutrients and recover energy in sidestreams of centralized WWTPs. Because the liquid effluent from engineered struvite precipitation often contains high concentrations of total nitrogen, I constructed and demonstrated a fixed-film nitrification reactor and a two-chambered MFC to further reduce total nitrogen and recover energy. The primary benefit of the MFC in the technology demonstrated here is not its ability to produce energy, but rather its ability to remove additional nitrogen through nitritation and denitritation. The sidestream nutrient removal prevents nutrients from returning to mainstream treatment, reducing operational costs. Such improvements to wastewater treatment processes can facilitate the transition to the resource recovery facility of the future by becoming a net-energy producer while also achieving the simultaneous benefits of nutrient recovery/removal and reduced costs associated with mainstream treatment. Nutrients and energy can also be recovered in agricultural settings. In this dissertation I studied an agricultural waste treatment system comprising a small-scale tubular anaerobic digester integrated with a low-cost, locally produced struvite precipitation reactor. This study investigated two digesters that treated swine waste in rural Costa Rica. I also facilitated construction of a pilot-scale struvite precipitation reactor that was built on site using local labor and local materials for approximately $920. Local products such as bittern (magnesium source) and soda ash (base) allowed for the production of struvite, a fertilizer that can replace synthetic fertilizer for rural farmers. Liquid-phase concentrations of PO43-P and NH4+-N in agricultural wastewater increased by averages of 131% and 116%, respectively, due to release from the swine waste during anaerobic digestion. Despite this increase in liquid-phase concentrations, an average of 25% of total phosphorus and 4% of total nitrogen was removed from the influent swine manure through sedimentation in the digesters. During struvite precipitation, an average of 79% of PO43-P and 12% of NH4+-N was removed from the waste stream and produced a solid with percentages (mass basis) of Mg, N, P of 9.9%, 2.4%, and 12.8%, respectively, indicating that struvite (MgNH4PO4) was likely formed. The treatment system offers multiple benefits to the local community: improved sanitation, removal of nutrients to prevent eutrophication, recovery of struvite as a fertilizer, and production of a final effluent stream that is suitable quality to be used in aquaculture. These are examples of how, more generally, quantifying nutrient recovery from agricultural waste and understanding recovery

Book Description :

As a low-lying delta region with a high population density, the Netherlands has long focused on the prevention of flooding catastrophes and the reclamation of valuable land. The evolution of Dutch water governance, beginning with the creation of local 'water boards' in the Middle Ages and growing into a complex infrastructure of polders, dams, and controlled waterways offers a compelling study of pitfalls and successes within one of the worlds most challenging regions for water management. Water Policy in the Netherlands traces the arc of water governance in the country, from technological innovations to prevent wide-scale flooding, to strategies focused primarily on improving water quality, to an integral water management approach which brings together perspectives from economics, hydrology, ecology, water law, and water technology. The contributions in this book demonstrate how both the technical and social sciences must play key roles in crafting policy in the face of serious environmental challenges including climate change, sea level rise, and increasing soil subsidence. Innovative themes explored in the work include: how economic models and pricing structures might improve efficiency in the distribution of water resources, how the competing uses for water-including for recreation, arable agriculture, fisheries, and natural preservation-create demands on both the quantity and quality of water resources, and how public participation, cogovernance, and the balance of public and private interests will be necessary to meet the goals of the EUs Water Framework Directive. This resource serves as both an invaluable case study and as a text to develop the analytical tool of integral water management for students, policy-makers, and NGO professionals in developed and developing regions.

Book Description :

Did you know that watching your favourite series on tv or just switching on your laptop for work, requires indirect water consumption? It’s a proven fact that every time we use energy resources, water is also consumed. In the next few decades, global water and energy demands will increase significantly, but at this time there isn’t a lot of information on expected global changes. The Water Research Institute (WRI) estimates that around 33 countries will experience very high water stress by 2040. Which means that as water scarcity rises due to rapid population growth, climate change and water deterioration, the global demand for pure water will also increase. We hope this book will help answer some of the challenges. The 13 chapters of this book were selected from multiple disciplines which focused on the state-of-the-art technologies in the field of environmental applications. These include technical-economic aspects of chemical precipitation; different substrates and concentrations of double chamber microbial fuel cells; the impact of pre-treatment on COD from paper industry wastewater; the synthesis of PES/Go-SiO2 mixed matrix membranes; predictions of a wastewater treatment plants performance of aeration demands; the performance of hydrological models for green roofs; short-term flexibility for energy grids from wastewater treatment plants; an integrated platform between water-energy-nexus and a business model for sustainable development; resilience-informed decision making in critical infrastructure networks. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

Book Description :

The most commonly used biological wastewater treatment technologies still have serious technical-economical and sustainability-related limitations, due to their high energy requirements, poor effluent quality, and lack of energy and resource recovery processes. In this thesis, novel electrochemical membrane bioreactors (EMBRs), which take advantage of membrane separation and bioelectrochemical techniques, are developed for wastewater treatment and the simultaneous recovery of energy and resources. Above all, this innovative system holds great promise for the efficient wastewater treatment and energy recovery. It can potentially recover net energy from wastewater while at the same time harvesting high-quality effluent. The book also provides a proof-of-concept study showing that electrochemical control might offer a promising in-situ means of suppressing membrane fouling. Lastly, by integrating electrodialysis into EMBRs, phosphate separation and recovery are achieved. Hence, these new EMBR techniques provide viable alternatives for sustainable wastewater treatment and resource recovery.
