Title (EN) WATER PROCESSING METHOD USING REVERSE-OSMOSIS MEMBRANE
(FR) PROCÉDÉ DE TRAITEMENT D'EAU UTILISANT UNE MEMBRANE D'OSMOSE INVERSE
(JA) 逆浸透膜を用いる水処理方法
Abstract:
(EN) Provided is a water processing method using a reverse-osmosis membrane, the method suppressing slime contamination even on a secondary side of the reverse-osmosis membrane, and suppressing oxidative deterioration of the reverse-osmosis membrane. A water processing method using a reverse-osmosis membrane, in which water to be processed is processed using the reverse-osmosis membrane, wherein a germicidal agent is caused to be present in the water to be processed, which contains ammonia, the germicidal agent containing a bromine-based oxidizer or a chlorine-based oxidizer, and a sulfamic acid compound.
(FR) L'invention concerne un procédé de traitement d'eau utilisant une membrane d'osmose inverse. Le procédé supprime la contamination de boue même sur un côté secondaire de la membrane d'osmose inverse, et supprime aussi la détérioration oxydative de la membrane d'osmose inverse. L'invention concerne également un procédé de traitement d'eau utilisant une membrane d'osmose inverse pour le traitement d'une eau à traiter, un agent germicide étant présent dans l'eau à traiter contenant de l'ammoniaque, l'agent germicide contient un oxydant à base de brome ou un oxydant à base de chlore, et un composé d'acide sulfamique.
(JA) 逆浸透膜の2次側においてもスライム汚染を抑制し、かつ逆浸透膜の酸化劣化を抑制する逆浸透膜を用いる水処理方法を提供する。被処理水を逆浸透膜で処理する、逆浸透膜を用いる水処理方法であって、アンモニアを含有する被処理水中に、臭素系酸化剤または塩素系酸化剤とスルファミン酸化合物とを含む殺菌剤を存在させる、逆浸透膜を用いる水処理方法である。
