Desalination Plants free essay sample

Desalination According to the Bible the first desalination experiment was conducted by Moses at the location of Mei Mara in the Sinai desert, where by initiating the introduction of a piece of bitter wood into bitter water Moses turned the formerly bitter fluid into potable water. The first recorded scientific report, chronicling a design for a desalination plant of seawater was produced in print by Thomas Jefferson, the American Secretary of State, in 1791. A directive for the workings of the technology were posted on notice boards in every ship, for use in every emergency. During the Second World War desalination devices were used by the troops of various armies of the world. During the early 1950s, research projects were extensive with the aim of reducing the price of the desalination process. The incorporation of a membrane layer process resulted in a major advancement to the technology. The advancement in living standard during the second half of the 20th century resulted in the outcome of increased water use. We will write a custom essay sample on Desalination Plants or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The daily water use for families and industry. Water, in the past has been described as a natural resource, easily accessible and cheap, has now turned into a precious commodity. One of the many reasons are given, the major one being growth of population, wasteful use of water, pollution of available water resources, and climate changes related to global warming. As the third millennium began, we are now involved in a world revolution, researching and setting in place desalination processes at a reasonable cost and continuing research to lower the costs further. This will enable the supply of water, at convenient prices for all, hopefully, especially in residential areas as well as advancement in the quality of life all over the world. Israel water budget in 2001, is between 200 million and 500 million gigalitres, a desalination plant constructed in Ashkelon, would be capable of producing 100 million gigalitres. The importance of the first production plants constructed create responsibility for the scientific teams and those whom approve plans, which will establish a precedent for those whom follow. This will create and makes sure environmental demands are met correctly. World wide the constructed seawater desalination plants are the preferred environmental options for reducing the budgets and strain on water supplies. But do not forget the nvironmental price of such plants and should be thoroughly researched before action is taken. The intention of the desalination plants is to reduce water resources strain in many areas around the world both in the immediate and in the future. The water desalination process offers diverse evidence of environmental benefits, sanitation, water softening, and quality of sewage efflu ents. But while desalination has environmental benefits there are also unfavorable environmental effects. Appropriate planning can minimize these effects on local environment in the surrounding districts of the desalination plants. The land use, the groundwater, the marine environment, noise pollution, and the carbon footprint from intensified use of energy. The impact over a wide area of land with coastal lands now in use for factories, therefore converting coastal land into an industrial zone instead of tourism and recreation. Groundwater is effected if pipelines carrying seawater or brine are laid above an aquifer. The case of feed drilling can also have an effect on groundwater. In these cases the aquifer might be damaged either by infiltration of saline water or by disturbances of the water table. The concentration of brine from a discharge pipe can impact over a wide region of the sea floor. Concentrated brine is a natural marine ingredient, and has a high specific weight that causes it to sink to the ocean floor without combining thoroughly with the ocean waters. There are also chemicals, added to the water in pre-treatment stages of the desalination process, which may harm the oceanic life in the area of the pipes outlet. The discharge pipe and placement of the pipe can also damage sensitive marine dwelling animals and plants.
