2022 China New Design pleated filter exporter - Pleated SPN series Cartridge Filter Pleated Filter Cartridge Pp Pleated Cartridge Filter – Wuhu

PP microporous folding filter element adopts ultra-fine polypropylene fiber membrane. The ultra-fine fiber has stable filtration accuracy and can effectively intercept small particles and colloidal sundries. The filtration efficiency is as high as 99.8%; The multi-layer structure design provides a high sewage holding space and filtering area, which has the characteristics of large sewage holding capacity and long service time.

（1） Disinfection method of filter element
1. Disinfect with the disinfection cabinet, take out the filter element from the plastic bag and place it in the disinfection cabinet at 121oc for 30 minutes
2. Without disassembly and disinfection, the filter element is installed in the filter according to the correct method (the interval between the fixed plate and the filter element is 0.5mm) Steam for 30 minutes.

（2） Identification of inlet and outlet flow direction of folding filter element
The folding filter element is generally of external pressure type. Water enters from the outside of the filter element and exits from the middle. The forward and reverse flushing can be carried out in different directions.

（3） Aperture recognition
The filter elements of regular manufacturers will be engraved with precision materials before leaving the factory. If not, it can only be detected by bubble pressure.
The use and cleaning of the folded filter element should not be used without washing. When the design flow is met (the pressure gauge difference before and after the flow drops significantly is 0.1MPa), please shut down the machine and open the filter to take out the filter element, wash the surface dirt with clean water, then soak it in 4% hydrochloric acid for 24 hours, then soak it in 4% sodium hydroxide for 24 hours, and then rinse it with clean water (remove two O-rings during soaking to prevent expansion).
