REJECTION ENHANCING COATINGS FOR REVERSE OSMOSIS MEMBRANES |
| 摘要 |
Reverse osmosis membranes treated with polymers bearing carboxylic acid groups and optionally pendant hydroxyl or amide moieties display enhanced salt rejection and/or increased water flux. This treatment is particularly useful for improving the membrane characteristics of cellulose acetate and polyamide membranes. |
