High Flow Rate Water Filter for Ultrafiltration System Pretreatment
High flow rate water filter is a large diameter pleated consumable filter designed to protect industrial ultrafiltration membrane systems on the upstream side. This liquid filter delivers high contaminant holding capacity and maintains low pressure drop under continuous large-volume raw water flow. It can work in combination 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 worldwide.
High flow rate water filter is a large-diameter pleated filter cartridge specially engineered for the pretreatment segment of ultrafiltration water treatment equipment. Installed on the upstream of UF membrane modules, this industrial filter captures suspended solids, fine silt, pipeline rust, colloids and granular contaminants in raw water before the water enters ultrafiltration membranes. By removing particulate pollutants in advance, it reduces the risk of membrane fouling, extends the service life of expensive UF membrane elements, and reduces the frequency of costly chemical cleaning cycles across the entire water treatment system.
Different from traditional small-diameter filter cartridges, the high flow rate water filter adopts a wide-diameter pleated structure, greatly increasing the effective filtration area of each single filter element. To meet the same total system flow requirement, far fewer filter cartridges need to be fitted inside filter housings. This feature lowers spare parts inventory pressure, speeds up on-site filter replacement work, and reduces long-term operating costs for water treatment plant operators and system integrators. When designing complete water treatment skids, engineers can pair this high flow rate water filter 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 high flow rate water filter uses 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, delivering stable structural integrity under frequent pressure fluctuations and continuous large-volume water flow. Whether you are replacing worn filter cartridges in an existing ultrafiltration production line or purchasing spare consumables for newly commissioned UF equipment, high flow rate water filter can provide stable and repeatable pretreatment filtration performance for industrial water treatment projects.
High flow rate water filter operates based on the 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 the 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 high flow rate water filter cartridges.
This filter 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 high flow rate water filter only removes solid particulate impurities and cannot capture dissolved ions; it serves purely as mechanical prefiltration before ultrafiltration membranes.

Every batch of high flow rate water filter 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.
Products comply with strict industrial filtration quality management standards. Each filter cartridge 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.
High flow rate water filter 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 lifespan. Service cycle depends on raw water turbidity, contaminant concentration and real operating flow rate. It is recommended to replace the filter 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 creates 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 rating to prevent installation mismatch.
A: Polypropylene material has good tolerance for weak acid and weak alkaline aqueous media. It is not suitable for long-term continuous use in high-concentration strong acid or strong alkali environments. Contact our technical team for assessment of special chemical medium working conditions.
A: The required quantity is calculated by total system flow rate, single-cartridge rated flow and raw water quality parameters. Calculate according to the technical datasheet and reserve a reasonable surplus to accommodate fluctuations in raw water quality.
