Basic knowledge of membranes


Permeation is a common natural phenomenon that occurs when two solutions with different concentrations are separated by a semi permeable membrane. In the process of natural infiltration, water passes through the membrane from the side with lower ion content and enters the solution side with higher ion content. This process will continue until the ion concentration on both sides of the semi permeable membrane is balanced; Or until the pressure difference formed by water penetrating the membrane is equal to the osmotic pressure of the solution.
