How to prevent scaling of reverse osmosis membrane in pure water treatment equipment for injection? Author: When it comes to pharmaceutical everyone will think of a rigorous profession, that it relates to the lives of countless people problem. In the production of injection drugs in pharmaceutical factories, its water can be used only after being treated by pure water treatment equipment for injection. In the process of using pure water treatment equipment for injection, reverse osmosis membrane is relatively easy to use in pure water treatment equipment for injection. Loss of materials, if the reverse osmosis membrane in the pure water treatment equipment for injection fouls, it will accelerate the loss rate of reverse osmosis, then how to prevent the fouling of the reverse osmosis membrane of the pure water treatment equipment for injection? 1 , Do a good job in the pretreatment of the raw water, pay special attention to the qualified pollution index, and at the same time, it should be sterilized to prevent the growth of microorganisms in the device, and pay attention to the damage of chloride ions to the membrane. 2. During the operation of pure water treatment equipment for injection, proper operating pressure should be maintained. Under normal circumstances, increasing the pressure will increase the water production, but if it is too large, the reverse osmosis membrane will be compacted. 3. The turbulent state of the brine side should be maintained to reduce the concentration polarization of the solution on the surface of the reverse osmosis membrane and avoid the precipitation of some insoluble salts on the surface of the membrane. 4. When the pure water treatment equipment for injection is out of operation, dosing and washing should be carried out in the short term, and formaldehyde protection should be added in the long term. 5. The water production of the reverse osmosis membrane of the pure water treatment equipment for injection is significantly reduced, indicating that the membrane is fouled or polluted, and chemical cleaning should be carried out. 6. Make a regular analysis of the raw water quality, and adjust the dosage of the scale inhibitor according to the water quality and the dosing plan provided by the technical support department. 7. Strictly prevent the running, emitting, dripping and leaking of the dosing equipment, and add the liquid medicine to the reverse osmosis inlet water to truly prevent scaling. 8. The flushing method after the shutdown of pure water treatment equipment for injection is changed to flushing with demineralized water. This is the end of the introduction on how to prevent the scaling of the reverse osmosis membrane of the pure water treatment equipment for injection. I hope it will be helpful to everyone. As an important component of the pure water treatment equipment for injection, the reverse osmosis membrane must be paid attention to. Maintenance work to increase the service life of the reverse osmosis membrane.
