Water On The Earth | Over 97 percent of water on this Earth is salt, 3 percent is freshwater. 2 Percent is freshwater locked in glaciers and polar ice, while less than 1 percent of freshwater is accessible, rainwater, groundwater, and rivers., The Water Cycle | Water cycle is a natural process by which water continuously goes around the Earth changing states. It gives most of our fresh water. Evaporation, Condensation, and Precipitation., What is Desalination | Desalination is a method of water purification. It is the process that takes dissolved salt out of sea water or brackish water. There are two main ways to desalinate., Desalination Method 1 | One way is via heating thermal water. (Thermal Desalination) The salt is left behind while the water is caught and condensed into fresh water., Desalination Method 2 | The other method is via reverse osmosis. It works as a microfilter, it forces salty water through membranes with tiny holes. They only let water pass through, and not salt. Although some other harmful organisms and bacteria still pass through., The 5 Stages in a Desalination Plant | There are normally 5 stages in a desalinization plant: Seawater intake, Screening, Ultrafiltration, Reverse Osmosis, and then water treatment. Sometimes, instead of Reverse osmosis, they use Thermal heating., Desalination Pro 1 | Desalination takes the salt and minerals out of sea water which renders the water safe to drink, Desalination Pro 2 | Desalination provides a reliable source of fresh water to all areas no matter if they have none or lots of fresh water., Desalination Pro 3 | Desalination can reduce pressure on existing freshwater resources., Desalination Pro 4 | Desalination provides a way to meet the growing water demand of cities and industrial areas., Desalination Pro 5 | Desalination helps improve water quality in polluted and clean areas., Desalination Pro 6 | Desalination is a long-term response to the problems created by a lack of fresh water., Desalination Pro 7 | Desalination removes unwanted compounds from seawater (usually salt, bacteria, viruses, and other pollutants)., Desalination Pro 8 | Desalination contains a very versatile and effective water treatment technology in reverse osmosis, which provides greater flexibility for water treatment., Desalination Pro 9 | Desalination can sustainably help commercial and industrial production and living activities in coastal areas to solve the problem of water scarcity, and to an extent reduce the use of other local natural water resources., Desalination Con 1 | Desalination is an energy-intensive process that requires a lot of electricity., Desalination Con 2 | The process of Desalination produces large amounts of brine that needs to be disposed of properly., Desalination Con 3 | The construction and maintenance costs of a desalination plant are relatively high..
