Some problems that need to be paid attention to when the small and medium reverse osmosis water purifier is running? Author: I believe we are not unfamiliar for small and medium sized reverse osmosis water will often see in our daily lives, not only to the domestic water brought us convenience, but also for our physical health foundation. Now small and medium-sized reverse osmosis water purifiers have a very high degree of automation, with sophisticated design and compact structure, which are suitable for large industrial enterprises. Small and medium-sized reverse osmosis water purifiers are developed using reverse osmosis technology. The cost of reverse osmosis membranes is high. Therefore, it is necessary to maintain and maintain the small and medium-sized reverse osmosis water purifiers correctly to avoid potential safety hazards. Now let's introduce the correct maintenance and maintenance methods of small and medium-sized reverse osmosis water purifiers. 1. Regularly check and replace the filter element of the precision filter in time to prevent the particle pollution of the reverse osmosis membrane of the pure water equipment caused by the leakage of the filter element due to installation or quality problems. 2. The mechanical filter is backwashed regularly. When backwashing is performed, compressed air gas friction is performed. After the backwash is qualified, stand for about 10 minutes and then perform the forward washing. After the washing water is qualified, it can be put into use. Do not bring air into the reverse osmosis. It also saves a lot of water for backwashing. 3. The inlet pressure of the high-pressure pump should be at least greater than 0.05MPa to prevent air or the retentate before the precision filter from being pumped into the reverse osmosis membrane of the pure water equipment by the high-pressure pump. In order to ensure the long-term, safe and stable operation of pure water equipment, it is necessary to do a good job in the management of small and medium-sized reverse osmosis pure water machines, timely discover changes in operating parameters and adjust equipment operating conditions. 4. The water quality of the water produced by the medium and small reverse osmosis water purifiers shall be tested and analyzed regularly, and the dosage of flocculants, fungicides, reducing agents and scale inhibitors shall be adjusted in time according to the actual situation. 5. When compared with the initial commissioning state, the water production of the reverse osmosis device of the standardized pure water equipment has dropped by 10, or the salt content of the produced water has increased significantly under certain conditions, or the pressure difference has increased by 15, the reverse osmosis membrane should be Clean in time. 6. The reverse osmosis membrane of the disabled medium and small reverse osmosis pure water machine should be flushed regularly at low pressure, especially in summer, it should be flushed once every shift. If the shutdown time is longer than 7 days, 0.5-1 sodium bisulfite or 0.5-1 formaldehyde solution should be used to protect the reverse osmosis membrane of the purified water equipment. And the pH value and concentration of the protection solution should be detected in time. 7. The inlet pressure of the high-pressure pump should be greater than 0.05 MPa to prevent air or the retentate before the precision filter from being drawn into the reverse osmosis membrane by the high-pressure pump. 8. The amount of concentrated water should be adjusted in time to maintain a recovery rate of about 75. The concentration of slightly soluble salts in the concentrated water should not exceed the solubility product and cause scaling, and water should not be wasted, that is, it should reach an economic operation state.
