In industrial production, reverse osmosis membrane are a kind of water purification components that are used more frequently. Many people will also ask such questions. How long are industrial reverse osmosis membranes used? How often should the reverse osmosis membrane be replaced? In fact, there is no clear and uniform answer to this question, but it depends on the specific usage.

It is normal for the reverse osmosis membrane to become fouled during use, but if it is not solved in time, it will inevitably shorten its service life. Some users say that GE reverse osmosis membranes will often become fouled during use. What is the cause? It must be understood clearly to ensure timely recovery of its performance.

1. Frequent water quality changes cause membrane fouling
The water quality of the raw water is the same as the design water quality, which increases the pretreatment load. As the influent water contains more impurities such as inorganic, organic, microorganism, granular and colloids, the probability of membrane pollution increases.
2. Membrane fouling caused by improper cleaning and incorrect cleaning methods
In the process of use, in addition to the normal degradation of membrane performance, improper cleaning and incorrect cleaning methods are also important factors that cause serious membrane pollution.
3. The medicine was not dosed correctly
In the use of composite polyamide membrane, because the polyamide membrane has poor resistance to residual chlorine, the use of disinfectants such as chlorine is not properly dosed, and the user does not pay enough attention to the prevention of microorganisms, which may easily lead to microbial contamination.
4. Film surface wear
The membrane element is blocked by foreign matter or the membrane surface is abraded (such as sand, etc.). In this case, detection method should be used to detect the elements in the system, find the damaged element, modify the pretreatment, and replace the membrane element.

It is normal for the reverse osmosis membrane to be polluted during the application. As long as the actual cause is found, the actual problem can be solved symptomatically. Correct maintenance can effectively extend the service life of the Brackish Reverse Osmosis Membrane. Therefore, it is necessary for the user to understand it accurately.

HUAMO reverse osmosis membrane needs to be cleaned regularly during long-term use in order to stabilize its filtration performance stability. In the previous article, common pollution phenomena and corresponding treatment methods are introduced. The operator knows how to judge the HUAMO RO Membrane Manufacturer. Whether it should be cleaned, but I don’t know the correct cleaning steps for GE reverse osmosis membranes, so today we will take a look:
1. Use a pump to pump clean, free chlorine-free reverse osmosis product water from the cleaning tank (or corresponding water source) into the pressure vessel and discharge it for a few minutes.
2. Use clean product water to prepare cleaning fluid in the cleaning tank.
3. Circulate the cleaning fluid in the pressure vessel for 1 hour or a preset time.
4. After the cleaning is completed, drain the cleaning box and rinse, and then fill the cleaning box with clean product water for the next rinse.
5. Use a pump to pump clean, free chlorine-free product water from the cleaning tank (or corresponding water source) into the pressure vessel and discharge it for a few minutes. 6. After flushing the reverse osmosis system, run the reverse osmosis system with the product water discharge valve open until the product water is clean, without foam or cleaning agents (usually 15 to 30 minutes).
Industrial reverse osmosis membranes generally have a very close relationship between the time of use and the place of use and the water quality. After using for a period of time, it is found that the effluent effect is not good or the water purification is not ideal. The reverse osmosis membrane is replaced.
