What countries desalinate water?
The world's largest desalination plant is the Jebel Ali Desalination Plant (Phase 2) in the United Arab Emirates. It is a dual-purpose facility that uses multi-stage flash distillation and is capable of producing 300 million cubic metres of water per year. By comparison the largest desalination plant in the United States is located in Tampa Bay, Florida, and operated by Tampa Bay Water, which began desalinating 34.7 million cubic meters of water per year in December 2007.The Tampa Bay plant runs at around 12% the output of the Jebel Ali Desalination Plants. The largest desalination plant in South Asia is the Minjur Desalination Plant near Chennai in India which produces 100,000 cubic meters of water per day, or 36.5 million cubic meters of water per year. According to International Desalination Association 2009, there are 14,451 desalination plants in operation worldwide, producing 59.9 million cubic meters per day (15.8 billion gallons a day), a year on year increase of 12.3%.
Is it possible to desalinate water from the ocean use it to make a green and lush Sahara in order to also prevent global water rise?
The amount of energy required to desalinate enough water would be huge, and anyway it would only irrigate the Sahara once. There is no soil there to retain the water and it would go straight through to the bedrock and drain way. To maintain a green and lush Sahara would require not just fresh water, but also soil to grow whatever grass or crops were planted and a climate in which they could grow.
humans do not drink all the water but to answer your question after it has passed through the body ending in urine nature re-filters it eventually back into clean water. Humans only drink a small proportion of the fresh water on the earth. and it keeps on replenishing itself as a result of rain. However human activity in the form of farming mining and industrial processes is putting a strain on its supply. Humans also…
97.5% of the earth's water is salty, and it is very expensive and tricky to desalinate (get the salt out of) salt water in large amounts. 1.7% of all water is frozen in the earth's icecaps, so it can not be used either. 0.7% is ground water, which we can access to a certain extent, and only 0.02% is from lakes, rivers, dams, etc., which isn't much!
The short answer is nothing. If there was a substance that absorbed salt, it would be employed to desalinate sea water into drinking water in many parts of the world already. There are some complicated and expensive processes that can "absorb" salt, although they rely on other energy inputs (chemical, pressure, filters) to force water away from salt, or salt away from water.
Yes. there are three basic methods for acquiring fresh water from sea water, with varying levels of complexity. The first and simplest method is to boil sea water, capture the steam, and as it condenses, the water will be fresh. the second way is to collect condensation by way of fog that forms off sea water. these two methods are only practical for very small amounts of water, or just enough to survive in a…
Remove the salty water and desalinate by evaporation, leaving the salt crystals behind. Condense the evaporated water vapour back into a liquid (water). Pass a strong electromagnet repeatedly over the sand and iron (iron filings?) mixture until all the iron has been removed, leaving the sand grains behind.
The hydrosphere is the combined mass of water found on under and over the earth's surface. Humans build wells to access underground water. They desalinate salt water to make it consumable for people and animals. They use it commercially. They filter it for deadly bacteria and parasites. They use it for agriculture, irrigation and gardening. They use it for recreation. We effect it with pollution, cleaning, fishing, mining, etc.
We know the boiling point of a substance can be changed by changing the pressure on it. Higher pressures increase the B.P. and lower pressures decrease the B.P. One example is a still that desalinates water. By heating the water a bit and decreasing the pressure as much as we can, we can get the water to boil at much less than its normal boiling point. That allows us to get the job done (run…
How do you desalinate water with a metal bucket bamboo saw palm leaves driftwood coconut and matches?
Take the metal bucket, fill it with water. Put it on the fire that you made with the palm leaves, driftwood, bamboo, and matches. Note: Do not put it directly on the fire, put if above the fire on a rack made of bamboo supported by driftwood. Let the water boil, have a palm leaf above the bucket. Drops of water should condense on the leaf, catch it with the empty coconut.
