Reverse Osmosis: Turning Saltwater to Freshwater
08:42 - 20:07 (11:25)
The process of reverse osmosis involves using a membrane to extract fresh water from saltwater, and it is a more energy-efficient method compared to traditional distillation using heat. The technology has been developed since the 1950s and offers a solution to the lack of freshwater resources in many parts of the world.

Summary
The global water crisis is a real problem that needs to be addressed for the near or far future. There have been efforts since the 1950s to turn saltwater into pure water, but the traditional method of distillation requires a lot of energy, leading to alternative methods being researched, with the ocean being an obvious place to look for a solution.

Summary
Reverse osmosis filters use an inner tube wrapped in a membrane to separate salt from seawater. By applying pressure, the water is forced through the membrane while the salt remains in the outer tube.
