It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastruc...
Sludge Treatment and Disposal is the sixth volume in the series Biological Wastewater Treatment. The book covers in a clear and informative way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described. About the series: The series is based on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other titles in the series are: Volume 1: Waste Stabilisation Ponds; Volume 2: Basic Principles of Wastewater Treatment; Volume 3: Waste Stabilization Ponds; Volume 4: Anaerobic Reactors; Volume 5: Activated Sludge and Aerobic Biofilm Reactors
Water is intricately linked with food security, energy security, and sustainable development. As the world is moving towards sustainable development goals, it is critical to recognize the role of water in attaining these goals. The Water-Energy-Food Nexus draws attention to the complex and interrelated nature of global resource systems and forces us to think about how a decision in one sector impacts other interlinked sectors as well. This book looks at the three dimensions of sustainable developmentenvironment, economics and society – and how water is linked with them and explores the nexus approach as a framework to look at the issues and identify solutions.
Human excreta is a valuable fertilizer for improving soil quality and crop productivity, with a potential to replace or complement the mineral fertilizers. The main challenges related to human excreta regarding agricultural applications are microbial contamination risks, loss of nutrients, and odor issues. Fertilization by lacto-fermented faeces supplemented by biochar has benefits such as improved soil bulk density, nitrate and potassium concentrations as well as the yield and yield components of corn, compared to untreated, simple stored faeces, urine, cattle manure, and unfertilized controls. Even though the mineral fertilizer produced corn with significantly higher height and leaf length...
The development of technology in the emergency sanitation sector has not been emphasised sufficiently considering that the management of human excreta is a basic requirement for every person. The lack of technology tailored to emergency situations complicates efforts to cater for sanitation needs in challenging humanitarian crisis. Concerns persists on the lack of faecal sludge management that considers the whole sanitation chain from containment until treatment. This study focused on the development of a smart emergency toilet termed the eSOS (emergency sanitation operation system) smart toilet to address the limitation in technical options. This toilet is based on the eSOS concept that takes into account the entire sanitation chain. This study also addresses the limited time for planning in emergencies by developing a decision support system (DSS) to help quick selection of optimal sanitation options. The aim was to enable users of the DSS to plan their emergency sanitation response within the shortest time possible. The study aims to contribute toward a better emergency sanitation response by application of technology advances.
Seawater desalination is a rapidly growing coastal industry that is increasingly threatened by algal blooms. Depending on the severity of algal blooms, desalination systems may be forced to shut down because of clogging and/or poor feed water quality. To maintain stable operation and provide good feed water quality to seawater reverse osmosis (SWRO) systems, ultrafiltration (UF) pre-treatment is proposed. This research focused on assessing the ability of UF and other pre-treatment technologies to reduce biofouling in SWRO systems. An improved method to measure bacterial regrowth potential (BRP) was developed and applied at laboratory, pilot and full scale to assess the ability of conventiona...
Design is inextricably interwoven with all aspects of life and has even produced its own astonishing genre of research. Design research opens up new perspectives of interdisciplinary empiricism, joining with economics, sociology, technology, and philosophy to produce analyses and syntheses that get to the heart of daily life. The twelve contributions from international authors that comprise this book vividly make this case. They cover the relationship between subject and object, animation, all forms of representation, design activism, and many other themes. This book is intended to inspire discussion. Its target reader is anyone seeking to expand their understanding of design, to fundamentally improve their praxis, and to more deeply appreciate life in all of its aspects.
Counter-Cola charts the history of one of the world’s most influential and widely known corporations, The Coca-Cola Company. Over the past 130 years, the corporation has sought to make its products, brands, and business central to daily life in over 200 countries. Amanda Ciafone uses this example of global capitalism to reveal the pursuit of corporate power within the key economic transformations—liberal, developmentalist, neoliberal—of the twentieth and twenty-first centuries. Coca-Cola's success has not gone uncontested. People throughout the world have redeployed the corporation, its commodities, and brand images to challenge the injustices of daily life under capitalism. As Ciafone shows, assertions of national economic interests, critiques of cultural homogenization, fights for workers’ rights, movements for environmental justice, and debates over public health have obliged the corporation to justify itself in terms of the common good, demonstrating capitalism’s imperative to either assimilate critiques or reveal its limits.
This book offers an informative and humorous deep dive into the future of the toilet - from creative uses for harvested "biosolids," to the bold engineers dedicated to bringing safe sanitation to the billions of people worldwide living without it.
This book directly links the notion of the commons with different design praxes, and explores their social, cultural, and ecological ramifications. It draws out material conditions in four areas of design interest: social design, commons and culture, ecology and transdisciplinary design. As a collection of positions, the diversity of arguments advances the understanding of the commons as both concepts and modes of thinking, and their material translation when contextualised in the domain of design questions. In other words, it moves abstract social science concepts towards concrete design debates. This text appeals to students, researchers and practitioners working on design in architecture, architecture theory, urbanism, and ecology.
