How can water molecules with the size of 0.324nm pass through the RO membrane with the size of 0.1nm
We all know that the filtration accuracy of RO membrane is 0.1nm (i.e. 0.0001) μ m) It can filter out bacteria, heavy metals and plasma in water.
Then the problem comes. Benzene molecules can be killed at about 0.5nm and Ca + ions can be killed at about 0.3nm. We can fully understand it.
But w...
