Large Diameter Pleated Filter Cartridge for Ultrafiltration Pretreatment
Large Diameter Pleated Filter Cartridge is a high‑capacity pretreatment consumable designed to protect industrial ultrafiltration systems from particulate contamination. This detailed liquid filter article explains structural advantages, technical indicators and practical selection guidance for large‑diameter filter products. You can pair your ultrafiltration equipment with reliable High Flow Filter Element to reduce membrane fouling and extend system service life.
Large Diameter Pleated Filter Cartridge is an upgraded industrial filter consumable specially developed for high‑flow‑rate water‑treatment pipelines, and it is widely installed on the upstream side of ultrafiltration membrane modules. Compared with traditional small‑diameter filter cartridges, its widened cylinder structure greatly expands the effective filtration area, which delivers outstanding advantages of high throughput, long service cycle and low‑frequency replacement.When building or upgrading an industrial ultrafiltration water‑treatment plant, matching your system with qualified Large Diameter Pleated Filter Cartridge can effectively intercept silt, rust, colloids, suspended solids and organic pollutants from raw water before the feed liquid reaches ultrafiltration membranes. Blocking these contaminants at the pretreatment stage significantly slows down membrane fouling, cuts the frequency of chemical cleaning, lowers long‑term operational costs and stabilizes the water yield performance of your ultrafiltration equipment.As a mature replacement solution, Pall high flow filter element – Drop‑in Interchangeable Ultipleat can serve as an ideal alternative for your large‑diameter filtration requirements. These drop‑in cartridges can be loaded directly into your existing High‑Volume Filter Housing without extra mechanical modification. For large‑capacity ultrafiltration projects, several large‑diameter pleated cartridges can replace dozens of standard small‑diameter elements. This reduces the total number of parts, saves installation space, decreases sealing‑joint leakage risks and greatly shortens downtime spent on routine filter‑replacement maintenance. Our factory also provides customized Large Diameter Pleated Filter Cartridge for special‑working‑condition ultrafiltration systems in chemical, food‑processing, petrochemical and power industries.
Large Diameter Pleated Filter Cartridge protects downstream ultrafiltration equipment based on surface interception and depth‑filtration principles. Untreated raw water flows from the pipeline into the filter housing and reaches the outer pleated surface of the large‑diameter cartridge. The intensive folded‑media structure creates a far larger dirt‑holding space than conventional small‑diameter filters. Suspended silt, rust debris, colloidal particles and organic impurities are trapped on the outer layers of the pleated material. Purified feed‑water permeates through the filter media and flows inward, finally discharging from the central inner core toward the ultrafiltration membrane modules.During long‑term continuous operation, intercepted contaminants will build‑up gradually on the outer surface of the Large Diameter Pleated Filter Cartridge. The contaminant cake will block partial water‑flow passages, which makes the pressure difference between filter inlet and outlet keep rising. When differential pressure increases 5‑10 psi above the initial working pressure, the cartridge has reached its pollutant‑holding limit and needs immediate replacement. If plant operators continue running a saturated filter element, raw‑water pollutants may bypass the filter media, flow downstream and pollute or scratch ultrafiltration membranes.When purchasing spare‑parts for your ultrafiltration pretreatment system, you can choose fully‑interchangeable filter cartridges such as PALL High Flow Water Filter Cartridge HFU640UY700H13W. Always verify the cartridge outer diameter, overall length, end‑cap connection style, O‑ring size and micron precision to avoid liquid bypass leakage and guarantee stable pretreatment protection for your ultrafiltration equipment.
Before ordering Large Diameter Pleated Filter Cartridge for your ultrafiltration pretreatment system, review the following core technical specifications for proper equipment compatibility:
Filter Media: Pure polypropylene pleated material, excellent chemical compatibility for aqueous solutions, no fiber‑shedding risk
Outer Diameter: Standard large‑diameter size 6.5 inch
Common Available Length: 20 inch, 40 inch, 60 inch
Micron Rating Options: 1 μm, 5 μm, 10 μm, 20 μm, 50 μm, 100 μm
Maximum Continuous Operating Temperature: 80 °C
Rated Working Pressure: 150 psi
Initial Pressure Drop: ≤ 5 psi at rated high‑flow rate
End‑cap Structure: Built‑in top lifting handle, double O‑ring sealing structure for leak‑free performance
Single‑cartridge Flow Capacity: Up to 150 m³/h depending on length and filter precision
For most industrial ultrafiltration pretreatment projects, 10 μm‑20 μm Large Diameter Pleated Filter Cartridge is the most popular selection. If your raw water contains high‑content fine colloidal pollutants, 5 μm‑grade cartridges are recommended to strengthen protection for ultrafiltration membranes. Custom‑made large‑diameter cartridges with special material or non‑standard dimensions can be supplied upon client request.
High‑quality Large Diameter Pleated Filter Cartridge is critical for the stable long‑time operation of your ultrafiltration water‑treatment system. Every production batch undergoes multi‑stage strict quality inspection before factory shipment. Raw polypropylene fiber materials are carefully screened to discard defective stock with loose‑fiber risk. Automatic pleating machinery precisely controls fold spacing to produce uniform pleats and maximize the effective filtering‑surface‑area. Hot‑melt thermal‑weld technology firmly bonds filter media and plastic end‑caps, effectively preventing liquid bypass leakage under high‑speed pipeline flow.Each finished cartridge needs to complete hydraulic pressure‑resistance testing, bubble‑point pore‑size detection and high‑flow pressure‑drop performance testing. Our whole manufacturing workflow strictly complies with ISO9001 international quality‑management standards. Complete batch‑level inspection reports can be provided for industrial clients who require quality documentation.Low‑quality large‑diameter pleated cartridges often suffer uneven pleats, weak thermal‑weld joints and fiber‑shedding defects. These hidden risks will send solid particles downstream and cause irreversible fouling damage to expensive ultrafiltration membranes. Investing in premium‑grade Large Diameter Pleated Filter Cartridge helps plant operators reduce ultrafiltration‑system maintenance costs and avoid unexpected production shutdown losses.
Large Diameter Pleated Filter Cartridge is widely deployed as pretreatment protection components for ultrafiltration and reverse‑osmosis equipment across multiple industrial sectors:
Municipal tap‑water and wastewater ultrafiltration treatment projects
Food‑and‑beverage processing water purification systems
Chemical‑industry circulating‑water and process‑liquid pretreatment
Petrochemical wastewater recycling ultrafiltration facilities
Electronics‑manufacturing ultra‑pure‑water production lines
Power‑plant boiler feed‑water filtration pretreatment
Large‑scale aquaculture water‑circulation ultrafiltration systems
Pharmaceutical factory process‑water treatment equipment
In all of these working‑condition scenarios, Large Diameter Pleated Filter Cartridge acts as the primary‑stage defensive barrier for ultrafiltration membranes. System operators need to monitor differential‑pressure data on a regular basis and replace saturated filter cartridges on time, so as to avoid unexpected membrane fouling and unplanned equipment shutdown.
A: It has a much larger effective filtration area, higher single‑cartridge flow capacity, longer service life, fewer replacement cycles, reduces the total quantity of filter parts inside filter housings and lowers maintenance workload.
A: Yes. It is one of the most‑recommended pretreatment consumables for industrial ultrafiltration systems. It intercepts suspended impurities and effectively protects ultrafiltration membrane modules.
A: 10 μm‑20 μm cartridges fit most general ultrafiltration projects. 5 μm‑grade cartridges are recommended if raw‑water contains a large amount of fine colloidal contaminants.
A: Service life depends on raw‑water quality. For relatively clean source water, cartridges can run for 3‑6 months. For heavily‑polluted water, replacement cycles are usually shortened to 1‑3 months. Rising differential pressure is the most reliable replacement indicator.
A: No. Pleated polypropylene cartridges are disposable depth‑filter products. Fine pollutants penetrate deep into filter‑media layers, and back‑washing cannot fully remove trapped contaminants. Reuse will greatly increase the fouling risk of ultrafiltration membranes.
A: Yes, interchangeable spare parts are available as long as the new cartridge matches your original element’s outer diameter, overall length, end‑cap interface, sealing specification and micron precision.
