Water desalination is the process of salt removal present in excess of mineral salts, microorganisms and other particles present in saltwater and bracking mainly of the oceans, transforming them drinking water. This procedure is performed through methods physicochemical, and about 97% of the water present on the planet are salty.
The desalination and pumping of this water provide quality of life improvements in several regions, but it is not yet a technology accessible to the poorest populations for wide-scale water use scale as in agriculture and in cases where the site is very far from units that carry out the process. Both desalination and pumping in more distant areas require a lot of energy for operation.
In addition to the high energy cost, water desalination generally uses fossil energy as a source —which is not sustainable—, presenting frequent changes in price and difficulty in transport. The use of solar, wind, geothermal and energy recovery are viable alternative to the use of this technology in a contributing manner to the preservation of environmental health.
Waste water (from sewers) has a concentration of much higher than the natural concentration found at sea, containing toxic waste that negatively affect marine ecosystems, such as chemical additives that are incorporated into the treatment of water and heavy metals corrosive processes occurring within pipes.
Through the development of technological advances that reduce energy consumption and minimize environmental impacts, desalination water would become accessible to poor populations, and is an important factor in to combat water scarcity around the world, contributing to significantly for improving the quality of life of billions of people.ACESSE AS REDES DA PANORAMA OFFSHORE:
