The emergence of purified water equipment provides a stable water supply system for the biopharmaceutical industry.
The effluent quality of purified water equipment meets various standards and is environmentally friendly and hygienic, ensuring water safety
.
For purified water equipment, the performance of reverse osmosis membrane is very important for purified water equipment.
Knowing that extending the life of reverse osmosis membrane of purified water equipment can ensure the service time of purified water equipment.
The following is an introduction to protecting the reverse osmosis membrane of purified water equipment Some coupes: 1.
The reverse osmosis membrane element is usually stored in a sealed plastic bag after soaking in 1% NaHSO3 and 18% glycerol aqueous solution
.
In the case that the plastic bag is not broken, it will not affect its life and performance if it is stored for about 1 year
.
When the plastic bag is opened, it should be used as soon as possible to avoid adverse effects on the components due to the oxidation of NaHSO3 in the air
.
Therefore, the film should be opened as much as possible before use
.
2.
After the test machine, we used two methods to protect the film
.
The equipment runs for two days (15-24h), and then uses 2% formaldehyde solution for maintenance, or after running for 2-6 hours, uses 1% NaHSO3 aqueous solution for maintenance (the air in the equipment pipeline should be exhausted to ensure that the equipment No leakage, close all inlet and outlet valves)
.
Both methods can achieve satisfactory results
.
The first method is more expensive and is used when the idle time is long, and the second method is used when the idle time is short
.
3.
In the process of use, in addition to the normal attenuation of performance, the attenuation of equipment performance caused by pollution is more serious
.
The usual pollution mainly includes chemical scale, organic matter and colloid pollution, and microbial pollution
.
Different types of pollution show different symptoms
.
There are also some differences in the symptoms of membrane fouling proposed by different membrane companies
.
