Industrial reverse osmosis membrane is an important filtration consumable of water treatment equipment. Its filtration performance determines the water production effect of water treatment equipment. However, industrial reverse osmosis membrane belongs to consumables and has a certain service life. After a period of use, the performance will gradually decline and become unusable. So how can we extend the service life of industrial reverse osmosis membrane and effectively save investment costs?

When the service life of industrial reverse osmosis membrane expires, the membrane performance must not be damaged first, and accurate operation must be performed from storage to use. Generally, new industrial reverse osmosis membrane needs to be soaked with 1% NaHSO3 and 18% glycerol aqueous solution and then stored in a sealed plastic bag. As long as the packaging is not damaged, there is no problem in storing it for about a year, but if the sealed packaging has been opened, it should be used as soon as possible to avoid adverse effects on the industrial reverse osmosis membrane.

After the water treatment equipment is officially tested, we need to use two methods to protect the industrial reverse osmosis membrane. After the test run for 15-24 hours, 2% formaldehyde solution is used. After running for 2-6 hours, use 1% NaHSO3 aqueous solution for maintenance (the air in the equipment pipeline should be exhausted, the equipment should not leak, and all inlet and outlet valves should be closed).

Through the above content, we can understand that the protective measures to extend the service life of industrial reverse osmosis membrane are actually very simple. The above two methods can achieve satisfactory results, but the difference is that one method is more expensive and is used when the idle time is long, while the second method is used when the idle time is shorter.
