Nano-Scale CMOS Analog Circuits: Models and CAD Techniques for High-Level Design

The concept of photoelectrochemistry applied to microbial fuel cells could be the future of sustainable wastewater treatment and for hydrogen recovery as a valuable energy source.

With the increase of recalcitrant organic pollutants in industrial wastewater, the need for a sustainable bio-electrochemical process has become pressing in order to ensure that treatment processes are coupled with some beneficiation advantages. Microbial fuel cells combine wastewater treatment and biological power generation. However, the resistance of these organic pollutants to biological degradation requires further adjustment of the system to improve sustainability through maximization of energy production.

Solar energy conversion using photocatalysis has drawn huge attention for its potential to provide renewable and sustainable energy. Furthermore, it might be the solution to serious environmental and energy-related problems. It has been widely understood for several years that the top global issues today are concerned with securing a clean supply of water and ensuring a reasonable price for clean energy. Researchers are studying advanced materials and processes to produce clean, renewable hydrogen fuel through photocatalytic and photoelectrocatalytic water splitting, as well as to reduce carbon dioxide from the air into fuels through photocatalysis. Limited progress is occurring in these areas.

The purpose of this book is to comprehensively cover the evolvement in the conceptualization and application of photocatalytic fuel cells, as well as make a critical assessment of the contribution in the field of sustainable wastewater treatment and renewable energy production.

This book contains nine specialized chapters that provide comprehensive coverage of the design of photocatalytic fuel cells and their applications, including environmental remediation, chemical synthesis, green energy generation, model simulation for scaling up processes and implementation, and most importantly maximization of hydrogen evolution, recovery, and applications.

This book presents technoeconomic challenges, recent trends, and developments toward sustainable algal biofuels and biorefinery. The exponential increase in population and thus the demand for energy, the ever-rising threats to climate change with conventional fossil fuels consumption, fluctuations in fossil fuels price and geopolitical instability have made each and every country of the world to think over its energy independence and security by increasing its own domestic energy production and reducing dependence on scarce fossil fuels. The global need to shift towards a sustainable source of energy has led to the discovery of third and fourth generation biofuels, in which microalgae and their genetically modified strains have been exploited. However, these simple photosynthetic organisms are difficult to select and cultivate for the production of biodiesel. Genetic engineering has opened provisions for the introduction of desired traits to such useful strains. There are also scopes for designing of novel photobioreactors (PBRs) having strain-specific physicochemical parameters, adequate CO2 and nutrient supply, and so on. The role of microalgae in CO2 sequestration from the environment is well known fact. Wastewater treatment plants can be used a raceway pond for the microalgal biomass production, and thus, obtained biomass can be used for biofuels and biochemical production.

Mathematical modelling can be used to understand the complex phenomena inside the photobioreactor, which can be a great help to overcome the limitations related to design and scale up of PBRs. Flow hydrodynamics in PBRs has significant effect on the microalgae growth. Computational fluid dynamics (CFD) can be used to study operating and geometry factors in PBRs that influence the flow dynamics, such as the inlet gas flow rate, mixing, mass transfer, reactor geometry. The use of artificial intelligence (AI) particularly artificial neural network model (ANN model), statistical and evolutionary learning-based techniques are some innovative approaches in manipulating and optimizing productivity and costs in algal biofuel production. This book is aimed to bring several aspects of algal biorefinery and microalgal biofuel production, challenges, and future perspective of microalgal biofuel production at a single place.

This book explains the main problems of industrial wastewater treatments and how they are being treated by innovative biological processes. The need for clean water in developing countries has become difficult to achieve as a result of globalization and industrialization and  because of an increase in population, urbanization, and per capita water use.

Residential, commercial, industrial, and educational institutions produce immense amounts of wastewater.  Wastewater is treated to extract toxins to produce processed effluent by physical, chemical, and biological processes. Most of these innovative treatment systems are membrane filtration, advanced oxidation processes, and electrochemical approaches, which are strongly committed to offering solutions to help protect public health and the environment.

For wastewater treatment, different forms of bioreactors are used which are reliable, cost-efficient, and effective in removing a wide variety of contaminants.

This book outlines the capacity of various bioreactors that are most widely used for the treatment of different industrial and domestic wastewater, such as a rotating biological contactor, biological fluidized bed reactor, packed bed reactor, membrane bioreactor, continuous stirred tank bioreactor, up-flow anaerobic sludge blanket reactor, and photobioreactor, etc.

Despite this, the acceptance of these technologies and their commercialization on an industrial scale, the performance is still limited. Therefore, a broader use of cost-effective in situ remedial approaches to natural phenomena like bioremediation is needed. The role of numerous bioreactors in industrial effluent treatment has, including recent developments, also been explored in depth. Furthermore, it includes the operational factors affecting their performances, advances in their architectural design, their amalgamation with the existing setup, scale-up studies, life cycle assessment of those reactors, materials and cost analysis, etc. This information helps the reader to understand the insight into the mechanism, pros and cons, moreover efficient utilization, and commissioning of bioreactors.

This book covers microbial electrolysis cells (MEC) for biohydrogen production and explores the basics, challenges, limitations and applications of this technology.
