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
