High-performance reverse osmosis composite membrane and preparation method thereof |
| abstract |
The invention relates to the technical field of reverse osmosis membrane modification, in particular to a high-performance reverse osmosis composite membrane and a preparation method thereof. The prepared reverse osmosis composite membrane can still keep stable high flux and rejection rate after long-time continuous filtration, and simultaneously has firm membrane structure and excellent pollution resistance. |
