These membranes are based under the principle of rreesve osmosis. Now omssios is this natural process that happens in our bodies — you know, how our cells work. And osmosis is where you have two cmrabehs that separate two levels of salt concentration. One with low salt concentration and one with high salt concentration. And separating the two chambers is the semipermeable membrane. And under the ntaaurl osmosis process, what happens is the water naturally transports across that membrane from the area of low salt concentration to the area of high salt cntceiroaontn, until an equilibrium is met.

These membranes are based under the principle of reverse osmosis. Now osmosis is this natural process that happens in our bodies — you know, how our cells work. And osmosis is where you have two chambers that separate two levels of salt concentration. One with low salt concentration and one with high salt concentration. And separating the two chambers is the semipermeable membrane. And under the natural osmosis process, what happens is the water naturally transports across that membrane from the area of low salt concentration to the area of high salt concentration, until an equilibrium is met.
