Can osmosis and dialysis happen at the same time? How?

Osmosis is the diffusion of water across a selectively permeable membrane, which is a barrier that has holes large enough to allow water molecules to pass but small enough to block certain molecules like salt or glucose. Water with solutes (substance dissolved in water) diffuses from an area of lower concentration of solutes to an area of higher concentration until the concentrations on both sides of the membrane are equal.

Dialysis is the separation of smaller molecules from larger molecules by using a differential permeable membrane (like the semi-permeable membrane for osmosis). This membrane has holes that allow smaller molecules to pass while blocking larger molecules in a solution.

They sound mutually exclusive to me.

It's okay, thank you very much!

Am I missing something? What did you figure out?
