Pleated Water Filter Element for Industrial Ultrafiltration Pretreatment
Pleated Water Filter Element is a pleated filtration consumable designed for upstream protection of industrial ultrafiltration membrane modules. This liquid filterdelivers high dirt holding capacity and stable low pressure drop under continuous large-volume raw water flow. It can work together with PARKER High-flow water filter cartridge and HFU640UY1000J high flow filter cartridge to build multi-stage prefiltration systems for raw water treatment skids. It provides reliable prefiltration solutions for municipal, power, chemical, food and beverage water reuse projects globally.
Pleated Water Filter Element is a large-diameter pleated filter cartridge specially developed for the pretreatment section of ultrafiltration water treatment equipment. As the core consumable component of the whole filtration system, it is installed upstream of UF membrane modules, tasked with capturing suspended solids, fine silt, pipeline rust, colloids and granular contaminants in raw water before the fluid enters ultrafiltration membranes. By removing particulate pollutants in advance, it greatly reduces the risk of membrane fouling, extends the service life of costly UF membrane elements, and lowers the frequency of expensive chemical cleaning cycles for the complete water treatment system.
Compared with conventional small-diameter filter cartridges, Pleated Water Filter Element adopts wide-diameter pleated construction, which dramatically expands the effective filtration surface area of each single filter cartridge. To meet the same total system flow demand, far fewer filter cartridges need to be fitted inside filter housings. This structural advantage reduces spare parts inventory pressure, speeds up on-site filter replacement operations and cuts long-term operating costs for water treatment plant operators and system integrators. When designing complete water treatment skids, engineers can match this Pleated Water Filter Element with Parker MFNP050-40N Fulflo Mega-Flow Large Diameter Filter and Replace Pall Ultipleat High-Flow Cartridge for Ultrafiltration to construct gradient multi-stage raw water prefiltration.
This pleated water filter element adopts glue-free thermal fusion pleating technology. No adhesive is applied inside the filter medium, eliminating the risk of glue dissolution and secondary water contamination caused by continuous high-speed water scouring. End caps and internal and external support cores are integrally molded polypropylene, which can maintain stable structural integrity under frequent pressure fluctuations and continuous large-volume water flow. The all-polypropylene material construction delivers excellent chemical compatibility, resisting most weak acid, weak alkali and aqueous solutions. Whether users need to replace aging filter cartridges in existing ultrafiltration production lines or purchase spare filter consumables for newly commissioned UF equipment, Pleated Water Filter Element can deliver stable and repeatable pretreatment filtration performance for all kinds of industrial water treatment projects.
Pleated Water Filter Element operates based on surface-depth composite pleated filtration principle. Raw water flows into the filter housing and travels radially inward starting from the outer pleated surface of the filter cartridge. Larger solid particles, rust fragments and sediment are trapped on the outer pleated layer. Fine colloids and tiny suspended particles penetrate into layered polypropylene fiber medium and get intercepted within dense fiber gaps.
Thanks to optimized wide-area pleat layout, captured pollutants spread evenly across the whole filter medium surface instead of stacking only on the outer layer. This slows the rising speed of inlet-outlet differential pressure, maximizes dirt holding capacity and extends the usable operating cycle of each filter cartridge. When the pressure difference between filter inlet and outlet hits the preset threshold value, the filter medium becomes saturated with trapped contaminants, and field operators need to install new Pleated Water Filter Element.
This filter element forms the primary protective barrier for ultrafiltration membranes. Without this upstream prefiltration, raw water loaded with solid particles will directly impact UF membrane surfaces. Contaminant deposits block membrane pores and flow channels, accelerate fouling, increase chemical cleaning frequency, and may even cause irreversible permanent damage to ultrafiltration membranes. When installed in series with PFTM11UEPFA high flow filter cartridge for multi-stage combined filtration, the long-term operational stability of the ultrafiltration system can be greatly enhanced. It is important to note that Pleated Water Filter Element only removes solid particulate impurities and cannot capture dissolved ions; it serves purely as mechanical prefiltration before ultrafiltration membranes.

Every batch of Pleated Water Filter Element undergoes full-process production inspection and finished-product performance testing before shipment. Incoming raw material inspection is carried out for polypropylene filter media, support cores and end caps to ensure consistent quality between batches. During manufacturing, sampling inspections check pleating uniformity, thermal bonding strength and end cap sealing integrity.
Finished product tests include bubble point integrity test, cyclic pressure impulse test and water flow pressure drop detection. Defective filter cartridges with medium cracks, poor sealing or loose structures are fully screened out. The glue-free thermal bonding process removes the risk of adhesive leaching that may contaminate process water. The all-PP material design also avoids the risk of metal shedding in the filtration process, suitable for many sanitary water treatment scenarios.
Products comply with strict industrial filtration quality management standards. Each filter element is individually packaged to avoid dust and particle contamination during storage and transportation. Complete technical datasheets are provided for engineering design, BOM creation and quotation reference. After installation and before system startup, on-site inspection should be performed to confirm filter housing interface matching and sealing integrity.
Pleated Water Filter Element is widely used as pretreatment filter element for ultrafiltration water treatment systems, and it also covers many other industrial liquid filtration scenarios.
Industrial ultrafiltration system pretreatment: Capture sediment, iron oxide scale and suspended particles, protect UF membrane elements, reduce membrane chemical cleaning frequency. Suitable for raw water purification and reclaimed water reuse projects.
Power plant water treatment: Pre-filtration for boiler makeup water and condensate water, removing pipeline rust and suspended particulate pollutants.
Food and beverage industry: Raw water pretreatment for drinking water and beverage production to remove granular impurities.
Chemical industry: Process water filtration and circulating cooling water pretreatment for chemical production lines.
Municipal water supply and reclaimed water reuse: Large-flow raw water prefiltration for municipal water plants and wastewater recycling projects.
Pharmaceutical and cosmetic purified water preparation: Sanitary grade prefiltration for water production equipment.
System designers can configure multi-stage gradient filtration according to raw water turbidity and pollutant composition of each individual project to achieve better overall filtration efficiency.
A: It serves as the upstream pretreatment protective filter for ultrafiltration systems. It intercepts suspended solids, silt and granular contaminants inside raw water, reduces pollutant load on UF membranes, slows membrane fouling, lowers chemical cleaning frequency and extends the service life of ultrafiltration membrane elements.
A: There is no fixed time-based service life. Service cycle depends on raw water turbidity, contaminant concentration and real operating flow rate. It is recommended to replace the cartridge when inlet-outlet differential pressure reaches 0.35 MPa.
A: It is a disposable pleated filter cartridge. Once fiber gaps are saturated with trapped contaminants, backwashing cannot fully restore original filtration performance. Reuse after cleaning brings particle leakage risks, direct replacement is recommended.
A: It fits 40-inch or 60-inch large flow filter housings with bayonet locking interface. Before ordering, verify housing interface dimensions, internal cavity space and pressure bearing rating to avoid installation mismatch.
