A METHOD FOR IMPROVING THE SEPARATION PROPERTIES OF SEMI-PERMEABLE MEMBRANES AND MEMBRANES ACCORDINGLY IMPROVED |
摘要 |
A method for improving the separation properties of semi-permeable membranes having penetrating defects due to the manufacturing process or subsequent handling and membranes accordingly improved. During a certain time one side of the membrane is exposed to a first chemical reaction partner and the other side of the membrane is exposed to a second chemical reaction partner so that in the penetrating membrane defects a chemical reaction will take place in a boundary region between the two reaction partners forming occlusions blocking said defects. |
