High Flow Pleated Filter Cartridge for UF Pretreatment Systems
High Flow Pleated Filter Cartridge is a primary consumable for industrial ultrafiltration pretreatment. This liquid filter uses pleated filter media to capture suspended solids and protect downstream UF membrane components. Our filter portfolio includes Parker MFNP005-40N Mega-Flow filter and HFU620UY100JEDF high flow filter cartridge for multi-stage raw water prefiltration packages. High Flow Pleated Filter Cartridge provides reliable and economical filtration solutions for desalination, power, chemical and wastewater reuse projects.
High Flow Pleated Filter Cartridge is a large-diameter filter element with pleated filter media, specially designed for the pretreatment section of industrial ultrafiltration water treatment equipment. It adopts pleating technology to fold filter material, greatly expanding the effective filtration area within a single cartridge body. Common filter media materials include virgin polypropylene, glass fiber and other polymer materials, and multiple micron grades are available to adapt to different raw water turbidity and pollutant characteristics. Installed upstream of ultrafiltration membrane modules, High Flow Pleated Filter Cartridge intercepts silt, rust, suspended particles and colloidal contaminants in raw water before the fluid enters UF membranes. Effective prefiltration reduces membrane fouling risk, extends the service life of expensive ultrafiltration membranes, and decreases the frequency of chemical cleaning and routine maintenance for the whole water treatment system.
The outstanding feature of High Flow Pleated Filter Cartridge is its ultra-high throughput capacity. Thanks to its large diameter and pleated structure, a single cartridge can handle far higher liquid flow than conventional small-diameter filter cartridges. This reduces the total quantity of filter cartridges required inside filter housings, shrinking equipment footprint, lowering spare parts inventory and simplifying on-site filter replacement work. When designing complete water treatment skids, system engineers can match High Flow Pleated Filter Cartridge with PFTM11UNPFA high flow filter cartridge and HFU640HGF100H1 high flow filter cartridge to build gradient multi-stage raw water prefiltration systems.
High Flow Pleated Filter Cartridge adopts thermal fusion forming technology without adhesive bonding. Filter media, internal and external support skeletons and end caps are thermally sealed together. This glue-free production eliminates the risk of adhesive dissolution and secondary contamination of process liquid under long-term liquid flushing. The raw material is virgin polymer, which has stable chemical resistance and low fiber shedding rate. Whether for upgrading existing ultrafiltration production lines or preparing spare filters for newly commissioned wastewater reuse systems, High Flow Pleated Filter Cartridge maintains stable and consistent filtration performance with excellent cost advantages.
High Flow Pleated Filter Cartridge operates with combined surface filtration and depth filtration mechanism. Raw liquid flows radially inward from the outer pleated surface of filter media, passing through multi-layer folded fiber web. Larger impurities such as sediment and iron rust are trapped on the outer pleated surface of filter media. Fine colloids and micro suspended solids penetrate into the inner fiber layers and get intercepted inside fiber gaps.
The pleated design maximizes the available filtration area of each cartridge, distributing pollutant loads evenly over the whole filter media surface. This slows the clogging speed of filter surface, delays the rise of differential pressure between filter inlet and outlet, and improves dirt holding capacity. When the pressure difference between inlet and outlet reaches the preset threshold, filter media becomes saturated with intercepted contaminants, and field operators need to shut down the system and replace the High Flow Pleated Filter Cartridge.
This filter cartridge acts as the first protective barrier for ultrafiltration membranes. Without sufficient upstream prefiltration, fine solid particles in raw water will scratch membrane surfaces, block membrane pores and cause irreversible fouling of UF membranes. When used in series with PFTM11UEPFA213 high flow filter cartridge for multi-stage combined filtration, the long-term stable running performance of ultrafiltration equipment can be significantly improved. It is important to note that High Flow Pleated Filter Cartridge can only remove solid particulate contaminants, and cannot eliminate dissolved ions, only providing mechanical prefiltration protection before ultrafiltration membrane units.

Each batch of High Flow Pleated Filter Cartridge undergoes full-process inspection and finished-product performance testing before delivery. Raw material inspection is carried out for 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 filter medium has stable structure and low fiber shedding rate under continuous liquid scouring, suitable for industrial pretreatment scenarios requiring consistent outlet water quality.
All products follow strict industrial filtration quality management standards. Each High Flow 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 bypass leakage.
High Flow Pleated Filter Cartridge is mainly used as pretreatment filter element 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.
Oil & gas produced water treatment: Pre-filter solid impurities before ultrafiltration of oilfield produced water.
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 has large effective filtration area, high dirt holding capacity, excellent chemical compatibility and compact installation structure. It is the preferred pre-filter element for industrial 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 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: Virgin polypropylene and glass fiber are mainstream options. PP media suits normal temperature water, glass fiber is selected for high-temperature liquid working conditions.
A: Quantity is calculated by total system flow rate, single cartridge rated flow and raw water quality. Reserve reasonable surplus to handle raw water quality fluctuation.
