There is a need for reliable, low maintenance off-grid desalination for drinking water in resource-constrained regions. However, current off-grid desalination systems rely on large solar arrays and battery capacity for sufficient power and energy storage - such systems greatly increase the capital costs, operating costs, complexity and maintenance. Electrodialysis is a flexible technology with significant energy and water efficiency in comparison to other thermal and membrane processes and thus provides significant reduction in solar array capacity; however, it has not been exhibited off-grid without significant energy storage. This work proposes and validates a simple, robust, and maximal water production rate control scheme which enables batteryless off-grid desalination. The control scheme proposed involves cascade control with an outer PID loop tracking power and commanding flow rate, and a coupled inner model based control loop which always produces the maximum allowable current and thus, maximum desalination rate for the real-time power. This control scheme is applicable and adaptable to any continuous power system but can be most advantageous in direct-drive variable power situations, such as with solar panels. The controller is extremely simple, computationally efficient, and robust to implement: it relies on two sensors - a flow meter and a conductivity meter, one equation, and a PID controller. We demonstrate and conduct initial validation of this capability in a field pilot using direct-drive photovoltaic batch electrodialysis. We demonstrate a battery reduction of 99.4% from comparable prior art (20 kwh to 120 wh) on a 2 kwh system at a control speed of 100 milliseconds and utilization of 79% and 91% of total solar energy on two separate days of testing. This control scheme enables significant reduction and even elimination of batteries and is a step towards minimal-maintenance, high production off-grid desalination.

Sustainability has become a sine qua non in the study and practice of engineering. This introductory textbook aims to make the concepts of sustainable engineering accessible to the undergraduate students of engineering. This will help them to keep in view the philosophy of sustainability while learning the core subjects of their specialisations and will equip them with a set of tools for this purpose. In addition to providing a broad-based introduction to the idea of sustainability and its relevance, the book talks about environment-related legislation, air and water pollution, solid waste management, local and global environmental challenges, climate change and the steps taken at an international level to manage them. Tools used to ensure sustainability in engineering activities such as Environmental Management Systems (EMS) and Environmental Impact Assessment (EIA) are mentioned. Green buildings, green computing, green chemistry, sustainable cities, sustainable transportation, sustainable sources of energy, economic and social factors affecting sustainability including rapid urbanization and poverty are also covered. A set of questions, some of them quite open-ended, are added at the end of each chapter to help students test their understanding. The reader is encouraged to use this book as a starting point to explore how the principles of sustainable engineering are relevant to their chosen branch of study and professional practice. The references given at the end of the book will serve as efficient guideposts in this journey which is well worth taking.

Water is synonymous with life. This has been the case since pre-historic time to the modern era. For the first time, humanity faces a crisis that eclipses the energy crisis, which has often incapacitated the global economy. The Climate-Water-Food nexus epitomizes our current civilization that depends on energy as the driver. Many recognize this crisis as a product of fossil fuel production, which allegedly triggered climate change and the “climate change debate.” Others predict the onslaught of “water wars” in the coming decades. As the world gears up to another lineup of empty promises and ensuing chaos, this book turns this crisis on its head and shows the source of the water crisis. The science behind the water cycle is described in clear language, without resorting to dogmatic assertions and spurious assumptions. The role of the sun, natural carbon dioxide (CO2) and water and the need to maintain natural processes free from artificial chemicals are discussed in detail. The book makes it clear how most of the currently used purification techniques violates the natural cycle involving sunlight, CO2 and water, and thus become unsustainable. A series of water purification techniques, as usable for drinking, agricultural and industrial applications are presented. The advantages of these techniques and their long-term sustainability are highlighted, with discussion on improvements in the future. Whether for the engineer or scientist working in the field or laboratory or the student, this is a must-have for any engineer, scientist, student, or policymaker.
