SOPHISTICATED TECHNICS
In reverse osmosis, the idea is to use the membrane to act like an extremely fine filter to create drinkable water from salty (or otherwise contaminated) water. The salty water is put on one side of the membrane and pressure is applied to stop, and then
reverse, the osmotic process.
A semipermeable membrane is a membrane that will pass
some atoms or molecules but not others
