The main points of the maintenance and maintenance of the reverse osmosis membrane of the small industrial reverse osmosis pure water equipment? Author: With the development of society, the development of water purification industry is also rapidly reverse osmosis membrane is applied to a variety of water purification equipment, small industrial reverse osmosis water equipment on the application of reverse osmosis technology, reverse osmosis membrane is why the People pay attention to it, of course, that reverse osmosis membrane is an indispensable water purification element for many water purification equipment, and the same is true for ultrapure water equipment. Any equipment is not purchased once and for all, and performance will decrease after a period of use. Let’s talk about the reverse osmosis membrane of permeable pure water equipment! After using for a period of time, the water purification effect and salt removal rate will decrease, which will affect the water quality of ultra-pure water equipment. So why the reverse osmosis pure water equipment of small industry Will the performance of the osmotic membrane decrease? The editor believes that the reverse osmosis performance of the small-scale industrial reverse osmosis pure water equipment is reduced because of the following reasons: 1. The performance of the reverse osmosis membrane is damaged, which causes membrane fouling. 2. Frequent changes in water quality cause membrane pollution: the water quality of the original water changes with the water quality at the time of design, which increases the pretreatment load. Since the influent water contains more impurities such as inorganic, organic, microbe, granular and colloids, the membrane is fouled The probability increases. 3. Membrane fouling caused by improper cleaning and incorrect cleaning methods: In addition to the normal degradation of membrane performance during use, improper cleaning and incorrect cleaning methods are also an important factor that causes serious membrane pollution. 4. Incorrect dosage of chemicals: The composite polyamide membrane is in use, because the polyamide membrane has poor resistance to residual chlorine, and the use of disinfectants such as chlorine is not properly added during use. In addition, the user does not pay enough attention to the prevention of microorganisms, which may easily lead to microorganisms. Pollution. 5. Membrane surface wear: Membrane elements are blocked by foreign matter or the membrane surface is worn out (such as sand, etc.). In this case, detection method should be used to detect the elements in the system, find the damaged elements, modify the pretreatment, and replace the membrane elements. 6. When a large number of pollutants are attached to the reverse osmosis membrane of the small industrial reverse osmosis pure water equipment, for example, due to the different treatment water quality, the degree of scaling on the reverse osmosis membrane surface of the small industrial reverse osmosis pure water equipment, and the state of the surface blockage The degree will also be different, so it is very necessary for the team to pretreat the water when performing the water treatment of the small industrial reverse osmosis pure water equipment; 7. The physical change of the reverse osmosis membrane of the small industrial reverse osmosis pure water equipment is caused by chemical changes. Caused by hydrolysis of the cellulose acetate membrane; free chlorine will also deteriorate the performance of the aromatic polyamide membrane; 8. Deposition on the reverse osmosis membrane surface of the small industrial reverse osmosis pure water equipment and the growth of a large number of bacteria will cause reverse osmosis for a long time The membrane is contaminated and blocked; 9. It is a common problem that many water purification equipment have, that is, the daily maintenance of small industrial reverse osmosis pure water equipment is not in place, and the regular maintenance of ultra-pure water equipment and ultra-pure water equipment required by manufacturers Internal components are cleaned and so on. This is the end of the introduction about why the performance of the reverse osmosis membrane of the small industrial reverse osmosis pure water equipment will decline. I hope it will be helpful to everyone. Knowing that it is caused by the above reasons, we must pay more attention to it when using it. Case.
