摘要： In the treatment, a reverse osmosis membrane element having a polyamide skin layer is loaded in a pressure vessel in a membrane separator and contacted with a bromide-containing aqueous solution of free chlorine. The thus treated reverse osmosis membrane element retains for a long time its effect of reducing solute concentration in a solution treated with the reverse osmosis membrane and rejects efficiently non-electrolytic organic materials or substances such as boron that will not be dissociated in a neutral region. Reverse osmosis membrane modules (5,12) having the thus treated reverse osmosis membrane elements are provided as well.

摘要： A fluorine-containing polyimide gas separation membrane which is pinhole-free, uniform over a large area, and has a high permeability and a high separation factor α is provided. A polyimide resin is dissolved in at least one solvent selected from the group consisting of an organic solvent (A) or (B). The organic solvent (A) has a dielectric constant of 30 or less and a dipole moment of 3.0D or less. The organic solvent (B) mainly contains an organic solvent having at least one ether bonding in the molecular unit. In the next step, the polyimide resin is dipped in a solvent (C) in order for desolvation. The solvent (C) does not dissolve the fluorine-containing polyimide resin while it is miscible with the organic solvent (A) or (B). As a result, an asymmetric gas separation membrane is formed. The fluorine-containing polyimide resin layer (3) comprises a skin layer (1) the thickness L 1 thereof is about 40nm and a sponge like layer (2) the thickness L 2 thereof is about 30 µm. The membrane is formed on a supporter (4) of, for example, an nonwoven cloth.
摘要翻译：提供了一种无孔无孔，大面积均匀的含氟聚酰亚胺气体分离膜，具有高磁导率和高分离系数α。将聚酰亚胺树脂溶解在选自由有机溶剂（A）或（B）组成的组中的至少一种溶剂中。有机溶剂（A）的介电常数为30以下，偶极矩为3.0D以下。有机溶剂（B）主要含有在分子单元中具有至少一个醚键的有机溶剂。在下一步骤中，将聚酰亚胺树脂浸渍在溶剂（C）中以进行去溶剂化。溶剂（C）在与有机溶剂（A）或（B）可混溶时不溶解含氟聚酰亚胺树脂。结果形成了不对称气体分离膜。含氟聚酰亚胺树脂层（3）包括其厚度L1约为40nm的表皮层（1）和厚度L2为约30μm的海绵状层（2）。膜形成在例如非织造布的支撑体（4）上。
