High Flow PP Pleated Filter Cartridge for UF Pretreatment Systems
High Flow PP Pleated Filter Cartridge is a widely adopted consumable for industrial ultrafiltration pretreatment. This liquid filteruses pleated polypropylene media to capture suspended solids and protect downstream UF membrane modules. Our product lineup includes Parker MFNP005-40N Mega-Flow filter and HFU620UY100JEDF high flow filter cartridge for building multi-stage raw water prefiltration packages. High Flow PP Pleated Filter Cartridge delivers reliable and cost-effective filtration for desalination, power, chemical and water recycling projects.
High Flow PP Pleated Filter Cartridge is a large diameter pleated filter element specially developed for industrial ultrafiltration pretreatment and general industrial liquid purification. Constructed from virgin polypropylene filter media, this filter cartridge adopts pleated structure to maximize available filtration area within a single unit. The polypropylene material offers excellent chemical compatibility, resisting most neutral aqueous liquids, weak acids and weak alkalis, making it the preferred pre-filter before ultrafiltration equipment. Installed on the upstream side of UF membrane systems, High Flow PP Pleated Filter Cartridge traps suspended particles, silt, rust and colloidal contaminants from raw water before fluid enters delicate ultrafiltration membranes. It effectively reduces membrane fouling risk, extends membrane operating lifespan, and lowers the frequency of chemical cleaning operations for the whole water treatment system.
Thanks to its wide diameter design, a single High Flow PP Pleated Filter Cartridge can handle much higher liquid throughput compared with conventional small bore filter cartridges. Fewer filter cartridges are required in filter housings to achieve the same system flow rate, reducing spare parts inventory and simplifying on-site maintenance and filter replacement. When designing complete water treatment skids, system designers can combine High Flow PP Pleated Filter Cartridge with PFTM11UNPFA high flow filter cartridge and HFU640HGF100H1 high flow filter cartridge to build gradient multi-stage raw water prefiltration systems.
This filter cartridge is manufactured with thermal fusion technology, no adhesive is used during assembly. The pleated PP media is combined with internal and external support skeletons, thermally sealed with polypropylene end caps. This glue-free production eliminates the risk of adhesive dissolution and secondary contamination of process water under continuous liquid flushing. The raw virgin polypropylene material avoids additive precipitation and fiber shedding. Whether for retrofitting existing ultrafiltration water lines or purchasing spare filters for newly commissioned UF systems, High Flow PP Pleated Filter Cartridge maintains consistent filtration performance with competitive cost advantages.
High Flow PP Pleated Filter Cartridge relies on surface and depth composite filtration mechanism. Raw liquid flows radially inward from the outer pleated surface of polypropylene media and passes through the multi-layer PP filter web. Larger particles such as sediment and rust are trapped on the outer pleated surface. Fine colloids and micro suspended solids penetrate into the inner layers of pleated polypropylene and get intercepted inside the fiber gaps.
The pleated design greatly expands the effective filtration area of each cartridge, distributing the pollutant load over a much larger media surface. This feature slows the build-up of contaminants, delays the rise of differential pressure between filter inlet and outlet, and increases the dirt holding capacity. When inlet and outlet pressure difference reaches the preset threshold, the filter medium becomes saturated with intercepted impurities, and operators need to replace the High Flow PP Pleated Filter Cartridge.
This filter acts as the first critical protective barrier for ultrafiltration membranes. Without adequate upstream prefiltration, fine solid particles in raw water will scour and block UF membrane pores, causing irreversible fouling and shortening membrane service life. When used in series with PFTM11UEPFA213 high flow filter cartridge for multi-stage combined filtration, the long-term running stability of ultrafiltration equipment can be significantly improved. It is important to understand that High Flow PP Pleated Filter Cartridge only removes solid particulate contaminants, and it cannot remove dissolved ions, serving purely as mechanical prefiltration protection before ultrafiltration membrane units.

Each batch of High Flow PP Pleated Filter Cartridge undergoes full-process inspection and finished-product performance testing before delivery. Raw material inspection is carried out for polypropylene filter media, support cores and end caps to ensure stable batch-to-batch quality consistency. During manufacturing, sampling inspections cover pleating uniformity, medium tensile strength, thermal sealing integrity and end cap connection performance.
Finished product tests include bubble point integrity test, cyclic pressure impulse test, flow pressure drop test and particle retention efficiency test. Any defective filters with medium cracks, poor sealing or loose structures will be fully screened out. The glue-free thermal fusion sealing eliminates adhesive leaching risk that may contaminate process liquid. Virgin PP filter medium has stable structure and low fiber shedding rate under continuous liquid scouring, which fits industrial pretreatment scenarios requiring consistent water quality.
All products follow strict industrial filtration quality management standards. Each High Flow PP Pleated Filter Cartridge is individually packaged to prevent dust and particle contamination during storage and transportation. Complete technical datasheets are provided for engineering design, BOM creation and quotation reference. After filter installation and before system startup, field technicians need to inspect filter housing interface and sealing condition to avoid fluid leakage.
High Flow PP Pleated Filter Cartridge is mainly used as pretreatment filter for ultrafiltration water treatment systems, and widely applied in various industrial liquid filtration scenarios.
Industrial ultrafiltration system pretreatment: Intercept fine suspended particles, silt and colloids, protect UF membrane elements, reduce membrane fouling and chemical cleaning frequency. Suitable for raw water purification and industrial wastewater reuse projects.
Power plant water treatment: Pre-filtration for boiler feed water and condensate water, removing fine suspended particulate impurities.
Seawater desalination industry: Prefiltration protection for ultrafiltration units in desalination plants.
Chemical industry: Process liquid filtration and circulating cooling water pretreatment for chemical production lines.
Municipal water reuse: Large-flow raw water prefiltration for municipal wastewater recycling plants.
Food & beverage water treatment: Raw water prefiltration for beverage and food production processes.
System designers can configure multi-stage gradient filtration scheme according to raw water pollutant composition and turbidity of each individual project to optimize overall filtration efficiency.
A: It features large filtration area, high dirt holding capacity, excellent chemical resistance and competitive price. It is the most cost-effective pre-filter option for ultrafiltration pretreatment.
A: There is no fixed replacement time. Service life depends on raw water turbidity, contaminant concentration and actual operating flow rate. Replace the cartridge once inlet-outlet differential pressure reaches 0.35 MPa.
A: It is disposable filter element. Once the PP pleated medium is saturated with trapped contaminants, backwashing cannot fully restore filtration performance. Reuse will bring particle leakage risk, direct replacement is recommended.
A: It is compatible with 40-inch or 60-inch high flow filter housings with bayonet locking interface. Confirm housing dimensions and pressure rating before ordering to avoid installation mismatch.
A: The maximum continuous operating temperature is 65℃. For working temperature exceeding this value, please contact our technical team for assessment and customized recommendations.
A: Quantity is calculated by total system flow rate, single cartridge rated flow and raw water quality. Calculate based on technical datasheet and reserve reasonable surplus to handle raw water quality fluctuation.
