Reverse
osmosis filtration system is used to treat ocean water,
waste-water, and even brackish, cloudy well water, to make them fit
for human consumption. This water purifying system is one of the most
advanced on the planet and is completely safe.
A good example of osmosis is the swelling of potatoes after you soak them in distilled water for some time. This indicates that the potatoes have absorbed the water, in a natural attempt to achieve a balance of water molecules in the potatoes and the distilled water outside. Reverse osmosis works the other way. It releases water molecules from a dense solution or source. However, reverse osmosis does not happen naturally. It needs applied pressure to push water molecules out of the dense solution.
