This course of Water Desalination Processes – Essential Concepts is a basic introduction, of the most important water supply system in many parts of the world, or could be for all in the future. Desalination is the process of removing salts and other minerals from the saline water to render it suitable for drinking, irrigation, or industrial uses. Development demands and climate change means that freshwater will be in chronically short supply in rich and poor areas of the world alike, there is increasing interest in desalination as a technique for tapping into the vast and infinitely tempting water supplies of the sea.
Renewable energy sources, such as, solar, wind, tidal, hydro, biomass, and geothermal have become significant sectors of the energy market. Seawater desalination is rapidly emerging as one of the major new sources of freshwater for the developed and some areas of the developing world, raising significantly the overall energy intensity, potential climate impact and cost of water supplies. Despite improved technologies and reduced costs, desalinated water remains highly expensive with high energy costs. However, our knowledge of the impacts and behaviors of the concentrated brines and diverse other chemicals issuing from the outlet pipe is far from comprehensive, both generally and in relation to particular sites.
In addition to the sea, there is a potential water supply in vast reserves of naturally brackish ground and surface water. Indeed, the lower concentration of salts means that the desalination of brackish water is often a more economic desalination proposition than pure seawater. Reverse osmosis membrane is the most used technology, which showed a great potential for increasing water use efficiency through recycling, for decontaminating water and for environmental repair through purifying or providing water for such purposes as rejuvenating wetlands, augmenting streamflows and recharging aquifers.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
