Description

Technical Field

[0001] The present invention relates to the technical field of reverse osmosis membrane performance detection, and in particular to a reverse osmosis membrane performance detection device and method. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation. Before the reverse osmosis membrane is put on the market, it is necessary to test its cleaning resistance.

[0003] The existing reverse osmosis membrane performance testing device will chemically clean the reverse osmosis membrane after it has been used for a period of time, and then perform performance testing after cleaning. When the cleaning liquid is introduced into the reverse osmosis membrane for cleaning, the impurities generated by the cleaning accumulate on the reverse osmosis membrane to form an alternative protective layer. The existence of this part of the protective layer is likely to cause the dirt on the reverse osmosis membrane to be not cleaned thoroughly, which will cause the remaining dirt to block the liquid during the subsequent separation performance test, resulting in errors in the final performance test results, reducing the use value of the performance testing device.
