Ultrafiltration membranes have a protective agent, and the membrane elements should be stored with a protective agent during storage.
The reverse osmosis membrane needs to be cleaned before storage, this purpose is to remove all contaminants and dirt on the surface of the membrane group, and it is recommended to use standard cleaning procedures for cleaning, so that the cleaning is cleaner.
2.The reverse osmosis membrane element should be kept in a moist state, which is to maintain the hydrophilicity of the membrane element.
3.The pH value of the reverse osmosis system should be kept within a certain range, otherwise the filtration effect of the membrane pack will be affected. Generally speaking, the pH value of the solution of the membrane group should not be lower than 3, and if the pH value of the storage solution is lower than 3, the preservation solution needs to be replaced in time.
If you are worried that the replacement will not be timely, you can change it once a month on a regular basis.
4.The suitable temperature for the storage of reverse osmosis membrane elements is 10-35, and the storage environment should be dry and dark, avoid direct sunlight, and it is best to place it indoors. Because the indoor temperature is relatively stable.
5.The outer packaging of the membrane element is stored in vacuum packaging to prevent air from entering the module.
6.Before it is put back into use, it is necessary to rinse the membrane pack with a low-pressure water gun for about 1 hour, and then use a high-pressure water gun to rinse the membrane pack within 10 minutes, as the membrane element may be damaged if it takes too long.
7.In general, the water temperature drops by 1 per hour. The water yield of the reverse osmosis membrane will drop by 3%, and the water yield of the reverse osmosis membrane in winter is usually half that of summer. When the water yield decreases, the wastewater flow rate increases, and the wastewater ratio increases. This is normal.

There is a protective agent inside the sealed bag of ultrafiltration membrane packaging. The most commonly used protective solution is a 1% sodium bisulfite solution.
Before long-term storage or unopened ultrafiltration membranes, there is a protective solution inside the ultrafiltration membrane elements.
-
rightleder.Before the use of ultrafiltration membranes, they are generally immersed in protective solution for sealing and storage to prevent shrinkage after dehydration of the wet membrane, and the membrane pores become smaller, so that the membrane structure is damaged and the water flux decreases.
Short-term storage: If the ultrafiltration membrane is suspended (less than 10 days), the ultrafiltration membrane should be sterilized and backwashed once, and 15ppm (ml L) of HY-240 fungicide should be added to the backwash water, and then the water inlet valve, discharge valve and regulating valve of the ultrafiltration membrane should be closed to maintain the sealing and sterilization of the ultrafiltration membrane.
Long-term storage: If the ultrafiltration membrane is stopped for a long time (more than 10 days), the ultrafiltration membrane should be sterilized and backwashed once, and then the HY-310 protective solution should be injected into the ultrafiltration membrane and sealed and stored (preferably RO water).

Summary. After the water source has been filtered with an overmold filter, it is generally not necessary to filter it again. Because the supermold filter can already remove impurities, odors, chlorine and other substances in the water, while also retaining trace elements and minerals in the water, so that the water quality is healthier and safer.
However, if you have special requirements, such as other needs for the taste of water, you can carry out secondary filtration according to the actual situation, such as using activated carbon filter cartridges. In addition, it should be noted that when using the supermold filter element, it needs to be replaced in time according to its service life to ensure the filtration effect and water quality. Generally speaking, the service life of the supermold filter is about 6 months, and the specific time needs to be judged according to the water quality and usage.
Replacing the filter cartridge regularly can extend the life of your water filter and also ensure that the quality of the water you drink is always at a good level.
After the water source has been filtered with an overmold filter, it is generally not necessary to filter it again. Because the supermold filter element can remove impurities in the water, such as Yunjiawei, peculiar smell, chlorine and other substances, it can also retain trace amounts of parapecin and minerals in the water when swimming in the same spike, so as to make the water quality more healthy and safe. However, if you have special requirements, such as other needs for the taste of water, you can carry out secondary filtration according to the actual situation, such as using activated carbon filter cartridges.

I'm sorry I don't understand, but can you elaborate on that?
In short, the use of supermold filters can indeed effectively filter harmful substances in water quality, but it is also necessary to pay attention to the maintenance and replacement of the filter elements to ensure their over-branch filtration effect and service life. In addition, although the supermold filter can filter out the water in the very or many harmful substances, but it is not guaranteed to be absolutely safe, it is best not to regard the supermold filter as a universal water treatment method, but also need to pay attention to the quality and quality of drinking water.

It is a kind of filter material, mainly for filtering colloids and macromolecules. It is used in pharmaceutical, food and beverage and other industries. Similarly, according to the pore size of the membrane and the size of the separated substance, there are microfiltration membranes, nanofiltration membranes, reverse osmosis membranes, dialysis membranes and so on.
-
It is mainly used for concentration or desalination, and is used for biochemical tests.

Ultrafiltration membrane is not similar to car membrane.

The effect of installing an ultrafiltration membrane can be divided into several aspects, depending on which area of the ultrafiltration membrane is installed, and the results will be different.
1. For example, it is installed in drinking water. Colloids, microorganisms (such as Escherichia coli), turbidity, rust and other substances in the raw water can be intercepted by the ultrafiltration membrane to ensure the quality of the effluent.
2. Ultrafiltration membranes are installed in some areas, enzyme preparations are concentrated, purified, and turbidity is removed by clarifying wine and soy sauce vinegar, which can achieve such an effect.
You have to tell me what you have installed, and it will have the corresponding effect!
Hope it helps.

In fact, it is very simple, that is, the substances in the water are physically filtered through the ultrafiltration membrane to achieve the effect of purification. Clean water molecules, as well as minerals in the form of ions in the water, can pass through ultrafiltration membranes due to their extremely small size; For example, dirty things such as rust and colloids are relatively large and cannot pass through the ultrafiltration membrane, so they are left in the membrane and washed away when the water is re-opened.
