Reverse osmosis membrane and reverse osmosis membrane apparatus |
| abstract |
A reverse osmosis membrane that can maintain high permeability for a longer time, a reverse osmosis membrane apparatus, and a hydrophilic treatment method for a reverse osmosis membrane. A reverse osmosis membrane to which poly(vinyl alcohol) is absorbed, wherein the poly(vinyl alcohol) is an ionic poly(vinyl alcohol). Preferably, adsorption of a cationic PVA to the reverse osmosis membrane is followed by adsorption of an anionic PVA. More preferably, an ionic polymer other than PVA is also absorbed to the reverse osmosis membrane. A reverse osmosis membrane apparatus including the reverse osmosis membrane. A hydrophilic treatment method for a reverse osmosis membrane, involving bringing the reverse osmosis membrane into contact with an ionic poly(vinyl alcohol). |
