Desalination معنى

Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination , which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water.

The largest part of its cargo was a desalination plant donated by an American chemical company in Ohio. The most common desalination methods employ reverse-osmosis in.

Water desalination processes separate dissolved salts and other minerals from water. In fact, a solar still can turn salt water into fresh water in just a few days. Simply fill a large bowl with salt water and set an empty glass at the center. English dictionary definition of desalination. However, desalination is not a fail-safe process and carries with it many environmental repercussions.

All desalination processes involve three liquid streams: the saline feedwater (brackish water or seawater), low-salinity product water, and very saline concentrate (brine or reject water). Solar desalination is a technique to produce water with a low salt concentration from sea-water or brine using solar energy. There are two common methods of solar desalination.

Either using the direct heat from the sun or using electricity generated by solar cells to power a membrane process.

Seawater reverse osmosis (SWRO) desalination has some environmental impacts associated with the construction and operation of intake systems and the disposal of concentrate. The primary impact of conventional open-ocean intake systems is the impingement and entrainment of marine organisms. DaVinci Studio to develop an animation that simplified the explanation of the process. Taking a cue from Seven Seas we.

It provides essential water for drinking and industry in desert regions or wherever the local water supply is brackish. Out of 935records in the U. It is possible the name you are searching has less than five occurrences per year. Of course, the recent California drought sent everyone back to their drawing boards, and the appeal of desalination has revived.

Scientists are studying ways to use desalination on a global scale, but you can desalinate water yourself with just a mug, a bowl, and some sunlight. The plant serves as a learning center for desalination research and a model for other inland cities facing diminishing supplies of fresh water. Lenntech is introducing the innovative Closed Circuit Reverse Osmosis (CCRO) technology to the water and process industry in Europe. CCRO is revolutionizing the purification and recovery of water across a variety of industries. Credit: Photo courtesy of IDE Technologies.

Membrane methods of desalination require energy for mechanical processes. Reverse osmosis is the most cost effective in many applications. Other considerations include the degree of purity require scale of production and cost of chemical pretreatments.

To quench the thirst of the United Arab Emirates, the equivalent of four billion bottles of water is desalinated every day. The biggest plant in the worl the Jebel Ali Phase plant, with an annual production of 3million cubic metres, is currently in the making.

Farid Benyahia wants to solve two environmental problems at once: excess carbon dioxide in the atmosphere and excess salt in the Persian Gulf (aka the Arabian Gulf). Global demand for clean water continues to accelerate, and municipalities and industries are looking for reliable, energy-efficient desalination solutions. As a leading provider of desalination technologies and support services, Flowserve brings safe, cost-effective water to communities.

We highlighted the biggest desalination companies before and not one of these companies was a publicly traded U. The water sells—depending on site conditions—for between $0and $5per acre-foot (the amount used by two five-person U.S. households per year).
