Nanostructured Photocatalysts: From Materials to Applications in Solar Fuels and Environmental Remediation addresses the different properties of nanomaterials-based heterogeneous photocatalysis. Heterogeneous nanostructured photocatalysis represents an interesting and viable technique to address issues of climate change and global energy supply. Sustainable hydrogen (H2) fuel production from water via semiconductor photocatalysis, driven by solar energy, is regarded as a viable and sustainable solution to address increasing energy and environmental issues. Similarly, photocatalytic reduction of CO2 with water for the production of hydrocarbons could also be a viable solution. Sections cover band gap tuning, high surface area, the short diffusion path of carriers, and more. - Introduces the utilization of nanostructured materials in heterogeneous photocatalysis for hydrogen fuel production via water splitting - Explains preparation techniques for different nanomaterials and hybrid nanocomposites, enabling improved sunlight absorption efficiency and enhanced charge separation - Assesses the challenges that need to be addressed before this technology can be practically implemented, particularly of identifying cost-effective nanophotocatalysts

Sterilizing water is a big job. Solar electric (PV) powered UV water sterilizers are an effective way to sterilize your water from local polluted sources, even brackish water, with safety, reliability, and no fuel-costs. Water found in nature is full of pathogens which can cause disease and illness. Ultra-violet (UV) sterilizers kill 99.99% of all dangerous pathogens and renders your water potable, and safe to drink. The need for water treatment usually occurs far away from an electrical outlet. Remote sites and locations, as well as occasions of Natural or Man-Made disaster, often need water treatment onsite, but lack the equipment and power supply to power the water sterilizing equipment on location. Solar PV powered UV water sterilizer systems offer complete solutions for remote-site water treatment and sterilization. This Book focuses on UV water treatment from 4 Gallons per Minute to 43,000 Gallons per Day - all Solar Powered. Included are specific Solar Power Supply examples, with included Parts Lists, to power these UV water sterilizing systems at your remote and off-grid location.

New and Future Developments in Catalysis is a package of seven books that compile the latest ideas concerning alternate and renewable energy sources and the role that catalysis plays in converting new renewable feedstock into biofuels and biochemicals. Both homogeneous and heterogeneous catalysts and catalytic processes will be discussed in a unified and comprehensive approach. There will be extensive cross-referencing within all volumes.The use of solar energy during various catalytic chemical processes for the production of an array of chemical products is the theme of this volume. Photocatalysis is a topic of increasing importance due to its essential role in many of today's environmental and energy source problems. The use of solar energy for catalytic reactions results in a carbon dioxide–neutral process. All photocatalytic processes and the future developments in this area are discussed, including an economic analysis of the various processes. - Offers in-depth coverage of all catalytic topics of current interest and outlines future challenges and research areas - A clear and visual description of all parameters and conditions, enabling the reader to draw conclusions for a particular case - Outlines the catalytic processes applicable to energy generation and design of green processes

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Developed in collaboration with the Nigerian Academy of Science, this report explores the ways in which science-based private enterprises can be created and encouraged in Nigeria and other developing countries to provide products and services that government is unable to supply in a timely and sustainable manner. Focusing on three critical challenges to health and developmentâ€"safe water, electrical lighting, and malaria therapyâ€"the report identifies a sample technology to address each of these challenges with potential for commercialization in Nigeria and Africa, and uses that sample technology to identify opportunities and barriers to creating the science-based enterprises in Nigeria.

The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some of these processes. AOPs have shown great potential in treating pollutants at both low and high concentrations and have found applications as diverse as ground water treatment, municipal wastewater sludge destruction and VOCs control. Advanced Oxidation Processes for Water and Wastewater Treatment is an overview of the advanced oxidation processes currently used or proposed for the remediation of water, wastewater, odours and sludge. The book contains two opening chapters which present introductions to advanced oxidation processes and a background to UV photolysis, seven chapters focusing on individual advanced oxidation processes and, finally, three chapters concentrating on selected applications of advanced oxidation processes. Advanced Oxidation Processes for Water and Wastewater Treatment will be invaluable to readers interested in water and wastewater treatment processes, including professionals and suppliers, as well as students and academics studying in this area. Dr Simon Parsons is a Senior Lecturer in Water Sciences at Cranfield University with ten years' experience of industrial and academic research and development.

The revised and updated second edition of Water and Sanitation Related Diseases and the Changing Environment offers an interdisciplinary guide to the conditions responsible for water and sanitation related diseases. The authors discuss the pathogens, vectors, and their biology, morbidity and mortality that result from a lack of safe water and sanitation. The text also explores the distribution of these diseases and the conditions that must be met to reduce or eradicate them. The text includes contributions from authorities from the fields of climate change, epidemiology, environmental health, environmental engineering, global health, medicine, medical anthropology, nutrition, population, and public health. Covers the causes of individual diseases with basic information about the diseases and data on the distribution, prevalence, and incidence as well as interconnected factors such as environmental factors.

Solar detoxification, an innovative process of water treatment using solar technology, is ready for practical application after a decade of research and development. This is of great significance as 70 per cent of the world's population currently lives within the 'sun belt', where sustainable solar technologies are feasible--a proportion due to increase in the future. Divided into two parts, the first part addresses the theory and fundamentals of water decontamination using solar energy. This prepares .the reader for the second part of the book, which addresses practical applications and engineering processes. Although the book targets university students and post graduates it can also be read by any professional or technician as all subjects are treated in depth, with scientific rigor, but are also attractively presented with a profusion of pictures and graphics. No specific previous knowledge is necessary.
