Osmosis may be used directly to achieve separation of water from a "feed" solution containing unwanted solutes.
Human creativity has also learned to take advantage of principles related to osmosis for such useful processes as desalination, water purification, water treatment, and food processing.
Forward osmosis is an area of ongoing research, focusing on applications in desalination, water purification, water treatment, and food processing.
Osmosis is an important topic in biology because it provides the primary means by which water is transported into and out of cells.
Osmosis can also be explained via the notion of entropy, from statistical mechanics.
Osmosis can also be seen very effectively when potato slices are added to a high concentration of salt solution.
The reverse osmosis technique is commonly applied in desalination, water purification, water treatment, and food processing.
Recent advances in pressure exchange and the ongoing development of low pressure membranes have significantly reduced the costs of water produced by reverse osmosis.
