What is the reason for the broken RO membrane of the portable industrial pure water equipment? Author: work portable industrial water equipment is the main application of the RO membrane device, so once the RO membrane portable industrial water equipment of any problems will affect the operation of the apparatus, then the RO membrane is broken below what causes it? Let me tell you about it. The excess gas left in the RO of the portable industrial pure water equipment runs quickly under high pressure, causing the air hammer to damage the RO membrane. First, after the device is evacuated, the pressure will gradually increase when restarting. Therefore, it must be ensured that the pressure of two to four bar will gradually increase after the excess air is exhausted. Second, if the pump and the device used are not very close. With good airtightness, the vacuum will suck in some air. Therefore, the micro filter should be replaced in time to ensure that the pipeline does not leak. The method is incorrect when the portable industrial pure water equipment is shut down. Once the device stops its normal operation, we need to add a certain amount of additives to it to make the TDS close by reducing the pressure; if the RO of the portable industrial pure water equipment is not disinfected well, it will cause a large number of microbial contamination. The pressure to be applied during operation must be far greater than the osmotic pressure of the solution within the allowable range of the portable industrial pure water equipment and membrane strength, generally several to several tens of times the osmotic pressure. When the aqueous solution of salt is in contact with the surface of the porous semipermeable membrane, a layer of water molecules is selectively adsorbed on the solution interface of the membrane. Under the action of the membrane pressure, pure water flows out through the capillary action of the membrane and continuously flows out to form a pure interface. Water layer. To sum up, this is the reason why the RO membrane of the portable industrial pure water equipment is broken. I hope to help you. If you have any questions, you can always consult the environmental protection equipment company. I believe you will not be disappointed.
