- Osmotic phenomenon in which a solvent moves from a solution having a low solute concentration toward a high solution between two solutions separated by a semipermeable membrane is called an osmotic phenomenon.
- applying an external pressure higher than osmotic pressure causes the solvent to move toward a solution with a low concentration of solute.
- This phenomenon is called reverse osmosis.
- a pressure gradient can be used as a driving force to separate various salts or organic substances through the semipermeable membrane.
- Reverse osmosis membrane using the reverse osmosis phenomenon is used to separate the material of the molecular level, remove the salt from the brine or sea water to supply the domestic, construction, industrial water.
- reverse osmosis membranes include polyamide reverse osmosis membranes, and polyamide reverse osmosis membranes are manufactured by forming a polyamide active layer on a microporous layer support, and more specifically, A polysulfone layer was formed on the nonwoven fabric to form a microporous support, and the microporous support was immersed in an aqueous solution of m-phenylene diamine (mPD) to form an mPD layer.
