What is reverse osmosis primarily used for?

Reverse osmosis is primarily used for desalinization of seawater, making it a crucial technology in areas where freshwater is scarce. This process involves applying pressure to seawater, forcing it through a semi-permeable membrane that allows water molecules to pass while blocking salt and other impurities. As a result, reverse osmosis effectively converts saline water into potable water, which is essential for drinking, irrigation, and various industrial uses.

The widespread application of reverse osmosis in desalination is especially important in regions with limited access to freshwater resources, such as arid coastal areas. By utilizing this technology, communities can create a sustainable source of drinking water, which is vital for health, agriculture, and economic development.
