Can the PES pleated filter element be used repeatedly?

There is a PES pleated filter element in the pleated filter element, which belongs to the deep filter element in the pleated filter element series. Its filtering effect is relatively stable compared with other water filter elements, and it is widely used in deep filter applications. For the PES pleated filter element, its material and composition are the keys to achieve deep filtration. The main material of the PES pleated filter element is polypropylene. It uses meltblown ultrafine fiber membrane as its filter medium. The filtration accuracy is divided into many types, ranging from 0.2μm, 0.3μm and up to 0.6μm. These precisions are all acceptable. Reached. The main feature of PES is that it is very stable and the filtration effect is relatively good. Not only the filtration accuracy is high, but the flow rate is relatively large, and the pressure drop can also be very low. It is called a fixed filter water filter element, mainly because the filter membrane of PES is It will not be affected by the shaking of the liquid, and its filtration accuracy has been in a relatively stable state, which is one of the reasons why it is favored by the majority of enterprises. In order to avoid waste of resources and reduce business expenses and costs, PES pleated filter elements can be used twice, but they need to be disinfected and cleaned. This work is very important, and there are many processing procedures and precautions. Disinfection method of PES folding filter element: ①Using a disinfection cabinet to disinfect the PES folding filter element. Put the used PES foldable filter element in the disinfection cabinet to ensure that the temperature of the disinfection cabinet is maintained at 121°C, and place the PES foldable filter element in the disinfection cabinet under this condition for about 30 minutes to complete the disinfection. ②Disinfect the filter directly. Without disassembling the filter, install the PES folded filter element into the filter. Pay attention to the installation of the filter, keep the distance between the fixed plate and the filter element at about 0.5mm, and then use steam for sterilization. The sterilization can be completed in about 30 minutes. How to clean the PES pleated filter element: ① Take out the PES pleated filter element from the filter for cleaning. Stop the filter first to prevent inconvenience when the machine is running, then open the filter, take out the filter element inside, rinse the surface of the filter element with clean water, and then soak it in hydrochloric acid. The neutralization rate of hydrochloric acid is about At about 4%, it needs to be soaked for 24 hours, and then soaked in sodium hydroxide with a neutralization rate of 4%, soaked for another 24 hours, and then taken out and rinsed with water. ②Use high-pressure water in the opposite direction to flush directly. The PES pleated filter element is an external pressure water filter element. The sewage enters through the outside of the filter element, and the filtered water is filtered out from the center of the filter element. When cleaning the PES pleated filter element, the PES pleated filter element can be flushed with high-pressure pulse water in the opposite direction. With strong water pressure, the dirt on the outer filter layer can be washed away. After the flushing is completed, simple cleaning and cleaning can be used again. This method is more convenient and fast.
