Ro Spare Parts are important filtration consumables for water treatment equipment. As its filtration performance determines the water production effect of water treatment equipment, ro spare parts belong to consumables and have a certain service life. After a period of use, the performance will gradually decline and eventually become unusable. How can the service life of ro spare parts be prolonged and the investment cost be effectively saved?

When the service life of ro spare parts expires, it is first necessary to ensure that the membrane performance is not damaged, and accurate operation is required from storage to use. Generally, new ro spare parts need to be soaked with 1%NaHSO3 and 18% glycerol aqueous solution and then stored in a sealed plastic bag. As long as the package is undamaged, there is no problem in storage for about one year. However, if the sealed package has been opened, it should be used as soon as possible to avoid adverse effects on ro spare parts.

We need to adopt two methods to protect ro spare parts after the water treatment equipment is formally tested. After the test machine is operated for 15-24 hours, then 2% formaldehyde solution is adopted. After 2-6 hours of operation, use 1% NaHSO3 aqueous solution for maintenance (exhaust all air in the equipment pipeline to ensure that the equipment does not leak and close all inlet and outlet valves).

From the above, we know that the protection measures to prolong the service life of ro spare parts are very simple. The above two methods can achieve satisfactory results, but the difference is that the first method is more expensive and can be used when idle time is long and the second method can be used when idle time is short.
