Purified water equipment management can mainly be used for the production and cleaning of various ultra-pure materials, reagents, laboratories, biotechnology experiments, electronic information products, etc. In recent years, with the promotion of environmental protection education concepts in our country, more and more industries, including the Chinese pharmaceutical industry, have attached great importance to water quality. The application research of purified water equipment has gradually expanded, and the requirements for the filtration effect of purified water equipment have also become more strict.
According to the working principle of the purified water equipment, the source water is simply converted into pure water. The source water is then transformed into the purification system of various levels of pure water machine equipment, filtering out impurities, organic matter, inorganic matter, malodorous gases and other insoluble substances in the water quality.
In water purification equipment, reverse osmosis membranes are the core components, and the water can effectively remove colloids, microorganisms, dissolved salts and other impurities.
Purified water equipment
It is worth mentioning that reverse osmosis membranes, as a special type of separation membrane material, have the advantages of low investment management cost, low energy consumption, high separation efficiency, advanced technological development, and wide application in China. Initially, they could be used in the construction of aerospace enterprises, but later they were gradually promoted to civilian and industrial applications. At present, reverse osmosis membranes have not been widely applied in fields such as medicine, food, beverages, and seawater desalination in society.
It is understood that the quality of reverse osmosis membranes in purified water equipment will affect the filtration effect, so the selection of membranes is very crucial. So how should users identify the quality of the membrane in the purified water equipment? What issues should be noted when purchasing reverse osmosis membranes? Some technicians from pure water equipment manufacturers suggest that it can be divided into "three steps".
Take a look
Users should observe the complete film in the membrane. It is fresh. Due to the influence of some external factors, it may lead to incomplete water purification by reverse osmosis membranes. The technician said so.
Second smell
It is understood that if affected by production and external factors, the membrane may deteriorate, and some may emit such a strange smell. If enterprises do not manage the storage properly for a long time, it will also cause some adverse social impacts on the reverse osmosis membrane of purified water. Therefore, user information can be studied simultaneously through the method of smelling to further determine the quality and quality of the membrane.
Three Inspections
Testing is also one of the effective methods to identify reverse osmosis membranes for purified water. It is reported that the water produced through high-quality reverse osmosis membranes contains no impurities, no salt and no minerals.
The preparation of reverse osmosis membranes is based on the selection of high salt retention and water flux as high as possible. The higher the desalination device, the denser the surface layer of the desalination film. In this field, it is indicated that users can focus on the tests of water flux and salt retention rate.
In addition, reverse osmosis is a membrane separation technology driven by economic pressure, thus it has high requirements for flexibility and mechanical design strength development. A good reverse osmosis membrane generally needs to have strong heat resistance and pressure resistance. User information can be analyzed and verified through this issue.
If it is applied in a special environment, users also need to test the physical, chemical and microbial erosion properties of the membrane, and observe whether it has good oxidation resistance and hydrolysis resistance.
Overall, users need to pay more to determine the reverse osmosis membrane. Considering all aspects comprehensively, in general, if the materials are of high quality and the workmanship is fine, the quality effect will be better and the service life will be longer.
