This study was preformed to look at the types of desalination that are used, and find out which current technique would be the best technique for city and rural use. This study could help make sure that when new desalination plants are being built, they would be using the best possible technique. There were five criteria for this project, the quality of water produced by the desalination technique, the quantity of water produced per day by the desalination technique, the energy needed to run the desalination plant, the supplies needed to build the plant, and the environmental impact that the plant has. Each criteria was ranked out of five, with at quantifiable criteria for each point. The results for this study was that Reverse Osmosis came first for the city usage, with Electrodialysis coming in second, Vapour Compression coming in third, Multiple Stage Flash coming fourth, and Multiple Effect Evaporators fifth. For rural desalination, the Double Basin Solar Still came first, Small Scale Electrodialysis came second, and Small Scale Reverse Osmosis came third. More research could be done on the best types of solar stills, and about more case specific to the area that the desalination plant is being put in.
