Singapore is a country with a lack of natural resources. Often these resources are imported to Singapore from other countries. However, this does not ensure that we will get a constant supply of natural resources if we keep depending on other countries. One such example is water imported from Malaysia, the water contract ends in 2050, and since Singapore depends heavily on the imported water from Malaysia, the country's leaders are desperately looking for other means of obtaining freshwater, such means include collection of water from reservoirs, NeWater and desalination. I have decided to do this science investigation project because I would like to find out more about how desalination uses evaporation to obtain pure water suitable for drinking. Desalination is a process where seawater is evaporated and the evaporated water is salt and impurity free - safe to drink. However as shown in the results of this experiment, salt water evaporates at a very slow pace, even slower than plain water, so heating is used to make the water evaporate faster. However desalination is not a very ideal because there are many factors that add to the operation costs and capital, including capacity, feeding water, location, energy and other factors. This makes desalination very costly.
