PES pleated filter cartridge, also known as polyethersulfone folding filter element, is a kind of folding filter element. It is folded by polyethersulfone membrane and is commonly used in the pharmaceutical industry. Because the filter element has absolute filtration accuracy, it is suitable for terminal precision filtration and can remove bacteria. Today, let me introduce this high-end filter element to you.
PES pleated filter cartridge adopts imported polyethersulfone membrane and imported non-woven fabric or (screen) the accessories for folding the inner and outer support layers, the center rod and end cover of the shell are made of polypropylene, the filter element is formed by hot fusion welding technology, the upstream and downstream support materials, support frame and structural elements are made of polypropylene, and the sealing materials are silicone rubber, NBR, EPDM rubber and fluororubber, without pollution and medium falling off. There is a PES folding filter element in the folding filter element, which is The folding filter element series belongs to the deep filter element. Its filtering effect is relatively stable compared with other water filter elements. It is widely used in deep filtration. For PES folding filter element, its material and composition are the key to enable it to achieve deep filtration. The PES folding filter element is mainly made of polypropylene. It takes the melt blown microfiber membrane as its filter medium. The filtration accuracy is divided into many kinds, with 0.2 μ m、0.3 μ M up to 0.6 μ m. These accuracies are attainable. The main feature of PES is that it is very stable and has good filtering effect. It not only has high filtering accuracy, but also has large flow and very low pressure drop. It is called fixed filtered water filter element, mainly because the filter membrane of PES will not be affected with the shaking of liquid, and its filtering accuracy has been in a relatively stable state, This is also one of the reasons why it is loved by the majority of enterprises. In order to avoid resource waste and reduce the expenses and costs of enterprises, PES folding filter elements can be reused, but they need to be disinfected and cleaned. This work is very important, and there are many treatment processes and precautions.
Disinfection method of PES folding filter element: use disinfection cabinet to disinfect PES folding filter element. Put the used PES folding filter element into the disinfection cabinet to ensure that the temperature of the disinfection cabinet is maintained at 121 ℃, place the PES folding filter element in the disinfection cabinet under this condition for about 30 minutes to complete the disinfection. Disinfect the filter directly. Do not disassemble the filter, install the PES folding filter element into the filter, pay attention to install the filter, keep the distance between the fixed plate and the filter element at about 0.5mm, and then disinfect with steam, which can be completed in about 30 minutes.
Cleaning method of PES folding filter element:
① Take the PES folding filter element out of the filter for cleaning. First shut down the filter to prevent inconvenient operation of the machine, then open the filter and take out the filter element inside. First wash the surface of the filter element with clean water, and then soak it in hydrochloric acid. The neutralization rate of hydrochloric acid is about 4%, which needs to be soaked for 24 hours. Then soak it in sodium hydroxide with a neutralization rate of 4% and soak it for 24 hours, Then take it out and clean it with clean water.
② Direct use of high-pressure water in the opposite direction to scour. PES folding filter element is an external pressure water filter element. Sewage enters through the outside of the filter element, and the filtered clean water is filtered out from the center of the filter element. When cleaning the PES folding filter element, the PES folding filter element can be washed with high-pressure pulse water in the opposite direction. The dirt on the outer filter layer can be washed off by using strong water pressure. After washing, it can be used again after simple cleaning and cleaning. This method is more convenient and fast than.
The PES folding filter element of LENGE company has the advantages of discount structure, large filtering area, low initial differential pressure, fast flow rate, small filter volume and low cost. Because the pre filtration and final filtration are combined into one, the filter element has a large dirt holding capacity. The service life is longer than that of the filter element with a single aperture. Single pure polypropylene material, easy to judge its chemical compatibility.
