Abstract: 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.

Abstract: A hydrodynamic method and apparatus are provided for forming tubular members useful in reverse-osmosis apparatus. A conventional film-forming liquid is forced through a tubular support by a pressurized column of gas to form a film of liquid on the inner wall of the tube. The liquid is then cured to solidify the film of liquid in tubular form. The disclosed hydrodynamic method and apparatus make possible an advantageous reverse-osmosis process and apparatus for recovering water of a low-salt concentration from saline water. 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 reverseosmosis operation can be resumed.
