What is different in dialysis and osmosis?

Dialysis is the process of separation of molecules. In dialysis, the solute molecules (such as salts, glucose, fats, etc.) are separated from larger molecules by the use of a permeable membrane. This membrane only allows the motion of small molecules across it, leading to separation of molecules. One of the most common daily life applications of dialysis is in the area of medicinal science. Dialysis is used for patients with kidney problems, and the process helps their bodies in cleaning the blood by removing ions, metabolic waste, toxins, and so on.
Osmosis is the process by which water molecules move from a region of low solute concentration to a region of high solute concentration across a semi-permeable membrane. In the case of osmosis in cells, the plasma membrane is the semi-permeable membrane. Unlike dialysis, osmosis applies to the movement of the solvent only. Osmosis is commonly used in the fields of biochemistry and pharmacology.
I hope this helps.
