How important is reverse osmosis?

Answer 1

Very important
It is reverse osmosis that turns salt water from the ocean—97% of Earth's water supply—into water that can be used for bathing, agriculture, and in some cases even drinking.


Not only is reverse osmosis used for making water safe, it is also applied to metals in a variety of capacities, not least of which is its use in treating wastewater from electroplating. But there are other metallurgical methods of reverse osmosis that have little to do with water treatment: metal finishing, as well as recycling of metals and chemicals. These processes are highly complicated, but they involve the same principle of removing impurities that governs reverse osmosis.

Answer 2

Reverse Osmosis - pushing a solutions through a filter to trap solute while allowing the solvent to pass through, using excess pressure.

It is important because it can be used as a water purification process.

Answer 3

it's a means of water purification.
