Question

What is the process of converting seawater into fresh water?

Answer 1

Hint: Saline water has large levels of dissolved salts (referred to as "concentrations"). The concentration in this context is the amount of salt in water (by weight), given in "parts per million" (ppm). If dissolved salts are present in water at a concentration of 10,000 parts per million (ppm), dissolved salts account for one percent of the water's weight.

Complete answer:
Distillation is a word used to describe the process of extracting alcohol from water. Desalination plants are used on a huge basis. Multi Stage flash evaporation plants are what they're called. Reverse osmosis is also utilised. Desalination plants require a lot of heat to evaporate water. Reverse osmosis facilities necessitate a lot of electricity. MSF evaporators operate in a vacuum environment.

Humans cannot drink saline water, but it may be converted to freshwater, which has numerous applications. The method is known as "desalination," and it is increasingly being employed around the world to give people with much-needed freshwater.

The "reverse osmosis" process is another way to desalinate saline water. Water containing dissolved salt molecules is driven through a semipermeable membrane (basically a filter), with the bigger salt molecules not passing through the membrane holes but the smaller water molecules passing through.

Although reverse osmosis is a good way to desalinate saline water, it is more expensive than other approaches. The use of reverse osmosis plants to desalinate huge amounts of saline water should become more prevalent as prices fall in the future.

Distillation desalination is one of humanity's earliest types of water treatment, and it is still widely used around the world today. Many ancient civilizations employed this procedure to transform seawater into drinking water aboard their ships. Desalination plants are now used to convert seawater to drinking water on ships and in many arid regions of the world, as well as to treat water that has been contaminated by natural and manmade toxins in other areas. Distillation is maybe the only water treatment process that totally removes the largest spectrum of pollutants from drinking water.

Note:-
In many dry places of the world, freshwater shortages and the need for new water supplies are already vital and will become more so in the future. Many desert places lack access to freshwater in the form of surface water such as rivers and lakes. They may have limited subterranean water resources, some of which are getting increasingly brackish as aquifer water extraction continues. Nature uses solar desalination evaporation to make rain, which is the world's primary source of freshwater.
