动态形成，反转的OSMOSIS膜

Dynamically formed,reverse osmosis membranes
摘要：
TUBULAR MEMBRANES ARE HYDRODYNAMICALLY FORMED WITHIN A POROUS TUBULAR SUPPORT TO FORM A POROUS STRUCTURE, AND SALINE WATER IS SUPPLIED UNDER PRESSURE TO THE INTERIOR OF THE RESULTING STRUCTURE TO RECOVER WATER HAVING A LOW SALT CONCENTRATION OUTSIDE OF THE TUBULAR SUPPORT. WHEN IT BECOMES NECESSARY TO REPLACE THE TUBULAR MEMBRANE, THE SUPPLY OF SALINE WATER IS DISCONTINUED AND

A SOLVENT IS FORCED AXIALLY ALONG THE TUBULAR MEMBRANE TO DISSOLVE IT. SUBSEQUENTLY, THE TUBULAR MEMBRANE IS HYDRODYNAMICALLY REGENERATED AND THE REVERSE-OSMOSIS OPERATION CAN BE RESUMED.
摘要（中）：

提供了用于形成用于反渗透装置的管状构件的流体动力学方法和装置。 常规的成膜液体通过加压的气体柱被迫通过管状支撑体，以在管的内壁上形成液体膜。 然后将液体固化以使管状的液体膜固化。 所公开的流体动力学方法和装置使得有可能从盐水中回收低盐浓度的水的有利的反渗透方法和装置。 管状膜在多孔管状载体内流体动力形成以形成多孔结构，并且将盐水在压力下供应到所得结构的内部，以回收管状载体外部具有低盐浓度的水。 当需要更换管状膜时，停止供应盐水，并沿着管状膜轴向强制溶剂使其溶解。 随后，管状膜被流体动力学再生，并且可以恢复反渗透操作。
