titleOfInvention | Excellent removing nitrate polyamide reverse osmosis membrane, Method of manufacturing the same and Membrane module comprising the same |
abstract | The present invention relates to a polyamide-based reverse osmosis membrane used in a household water purifier, wherein the conventional polyamide-based reverse osmosis membrane had a low nitrate removal rate under city water conditions containing a high concentration of hardness-inducing substances. The reverse osmosis membrane prepared by secondary coating with a specific amine compound has a relatively high surface negative charge concentration, that is, as the electrostatic attraction between the hardness-inducing material and the surface of the separation membrane is weakened, the surface accumulation of the hardness-inducing material is reduced. , to provide a reverse osmosis membrane having an excellent nitrate nitrogen removal rate, a method for manufacturing the same, and a membrane module including the reverse osmosis membrane. |
