DOWNLOAD EBOOKNanostructured 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

DOWNLOAD EBOOKSterilizing 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.

DOWNLOAD EBOOKLegionnaires' 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.

DOWNLOAD EBOOKDeveloped 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.

DOWNLOAD EBOOKSolar 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.

DOWNLOAD EBOOKRainwater tank systems have been widely adopted across the world to provide a safe local source of water in underdeveloped rural areas, a substitution for mains water for non potable end uses in water stressed urban areas, as well as providing flooding control in monsoonal climates such as Korea, or combined sewer systems such as Germany. The importance of these systems in cities has grown, as water managers seek to provide a range of decentralised solutions to supply constraints of current water supply systems, whilst reducing the impact of urban development on the natural environment, and increasing resilience to the impacts of climate change. Rainwater tank systems are now often implemented under integrated urban water management (IUWM) and water sensitive urban design (WSUD) philosophies, which take a holistic view of the urban water cycle. Rainwater Tank Systems for Urban Water Supply is based on a comprehensive, multi-million dollar research program that was undertaken in South East Queensland (SEQ) Australia in response to the Millennium drought when the water supply level in the regions drinking water dams dropped to 17% in July 2007 and the area came close to running out of water. In particular, the book provides insights and detailed analysis of design, modelling, implementation, operation, energy usage, economics, management, health risk, social perceptions and implications for water quality/quantity of roof water runoff. The approaches and methodologies included in Rainwater Tank Systems for Urban Water Supply inform and validate research programs, and provide insights on the expected performance and potential pitfalls of the adoption of rainwater tanks systems including: actual harvested yield and resulting mains water savings, optimal sizing for rainwater storages and roof collection systems, expected water quality and implications for managing public health risks, modelling tools available for decision support, operation and management approaches of a decentralised asset at the household scale and community acceptance. The book is suitable for use at undergraduate and post graduate levels and is of particular interest to water professionals across the globe, who are involved in the strategic water planning for a town, city or a region. It is a valuable resource for developers, civil designers, water planners, architects and plumbers seeking to implement sustainable water servicing approaches for residential, industrial and commercial developments.
