Pall Ultipleat High Flow Filter for Industrial UF Pretreatment
Pall Ultipleat High Flow Filter acts as a critical pretreatment component for industrial ultrafiltration systems. This liquid filter delivers outstanding dirt‑holding capacity and reduces the frequency of regular cartridge change‑outs. Built with high‑strength pleated polypropylene media, it fits most standard large‑flow filter housings and can work together with High‑flow water filter cartridge and Water Filtration PP Pleated Filter to construct complete multi‑stage water‑treatment workflows. It gains broad application in power, chemical, food‑beverage process water purification projects around the globe.
Pall Ultipleat High Flow Filter is a mature large‑diameter high‑flow pleated filter cartridge designed for upstream protection of ultrafiltration membrane equipment. As a drop‑in interchange industrial filter element, it is installed at the front of ultrafiltration membrane modules to capture suspended solids, colloids, fine sediment, pipeline rust and various granular contaminants within raw water. By removing most particulate impurities in advance, it effectively mitigates membrane fouling risk, lowers chemical cleaning frequency and extends the service lifespan of expensive ultrafiltration membrane elements.
Different from conventional small‑size filter cartridges, the Ultipleat series adopts exclusive large‑diameter pleated construction, greatly increasing the effective filtration area per single cartridge. Under identical flow conditions, fewer filter cartridges are required inside filter housings. For system integrators and end‑users, this brings tangible benefits: fewer filter housing units, simplified installation procedures and decreased long‑term operation and maintenance costs. When configuring the full water‑treatment skid, users can pair it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to realize multi‑stage gradient pre‑filtration interception performance.
This filter cartridge adopts glue‑free thermal‑bond pleating technology, eliminating secondary water pollution risks caused by adhesive dissolution under long‑term water scouring. End caps and inner‑outer support skeletons are integrally molded, maintaining stable mechanical performance under continuous high‑flow impact and frequent pressure fluctuations. Whether for newly commissioned ultrafiltration water‑making systems or spare‑part replacement of existing water‑treatment production lines, Pall Ultipleat High Flow Filter can offer consistent and reliable pretreatment filtration performance.
Pall Ultipleat High Flow Filter applies surface‑depth composite pleated filtration principle. After raw water flows into filter housing, fluid passes radially inward from the outer surface of filter cartridge. Large solid particles are trapped on outer pleated surface firstly, while tiny micro‑impurities penetrate into polypropylene fiber layers and are intercepted inside dense fiber gaps.
Benefiting from optimized Ultipleat large‑area pleated layout, pollutants are evenly distributed across the whole filter medium instead of accumulating only on partial surface zones. This design slows down differential‑pressure rising speed, maximizes dirt‑holding capacity and prolongs the effective working cycle of filter cartridge. When inlet‑outlet pressure difference reaches preset threshold value, it indicates filter medium is saturated with intercepted pollutants, and operators need to replace the whole filter cartridge.
It serves as the front‑line protective barrier for ultrafiltration equipment. Without this pretreatment safeguard, particle‑laden raw water will directly flow onto UF membrane surface. Solid contaminants will deposit on membrane surface, block membrane pores, accelerate fouling development, increase chemical‑cleaning frequency and may even lead to irreversible membrane damage. When used in series with PFTM11UNF high flow filter cartridge for multi‑stage combined filtration, the overall stability of water‑treatment systems can be further improved. It should be noted that this filter cartridge only removes solid particulate contaminants and cannot eliminate dissolved ions in water, so it only undertakes pretreatment work before ultrafiltration membranes.

Every batch of Pall Ultipleat High Flow Filter undergoes full‑process production inspection and finished‑product testing before shipment. Incoming material inspection is carried out for polypropylene filter media, support skeletons and end‑cap raw materials to guarantee batch‑to‑batch consistency. During manufacturing process, sampling inspections cover pleating uniformity, thermal‑bond strength and end‑cap sealing performance.
Finished‑product tests include bubble‑point integrity test, cyclic pressure impulse test and water‑flow pressure‑drop inspection. Defective units with medium cracks, poor sealing or structural looseness will be fully screened out. Glue‑free thermal‑bond process avoids adhesive‑dissolving risks that would contaminate process water.
Products are manufactured under industrial filtration quality‑management standards. Each filter cartridge is individually packaged to prevent dust and particle contamination during storage and transit. Complete technical datasheets are provided for engineering reference. On‑site installation inspection is still required before equipment startup to confirm filter housing interface matching and sealing integrity.
Pall Ultipleat High Flow Filter is mainly deployed as pretreatment filter for ultrafiltration water‑treatment systems, and it is also widely applied in multiple industrial liquid‑filtration scenarios.
Industrial ultrafiltration system pretreatment: Capture sediment, iron‑oxide scale and suspended particles, protect UF membrane elements, reduce membrane cleaning frequency, fit for raw‑water purification and circulating‑water treatment projects.
Power plant water treatment: Pre‑filtration for boiler make‑up water and condensate water, remove pipeline rust particles and suspended pollutants.
Food & beverage industry: Raw‑water pretreatment for drinking‑water and beverage manufacturing, filter granular impurities.
Chemical industry: Process‑water filtration and circulating cooling‑water pretreatment for chemical production lines.
Municipal water‑supply & reclaimed‑water reuse: Large‑flow raw‑water pre‑filtration for municipal water plants and water‑recycling projects.
Pharmaceutical and cosmetic water preparation: Sanitary‑grade pre‑filtration for process‑water making equipment.
Users can configure multi‑stage gradient filtration according to on‑site raw‑water turbidity and pollutant composition of different projects to acquire better overall filtration performance.
A: It acts as ultrafiltration pretreatment protective filter. It intercepts suspended solids, sediment and granular contaminants in raw water, lowers pollutant load on ultrafiltration membranes, slows down membrane fouling, reduces chemical‑cleaning frequency and extends UF membrane service life.
A: There is no fixed time‑based service‑life standard. Service cycle is determined by raw‑water turbidity, pollutant concentration and actual operating flow. It is suggested to replace the cartridge when inlet‑outlet differential pressure reaches 0.35 MPa.
A: It belongs to disposable pleated filter element. Once filter‑medium gaps are filled with intercepted pollutants, back‑washing cannot restore original filtration performance. Re‑use after cleaning brings particle‑leakage risk, direct replacement is recommended.
A: It is compatible with 40‑inch or 60‑inch large‑flow filter housings with special Ultipleat locking interface. Before purchasing, please verify housing interface dimension, inner‑chamber space and pressure‑bearing rating to prevent installation mismatch.
A: Polypropylene material has good tolerance for weak‑acid and weak‑alkali aqueous media. It is not suitable for long‑term exposure to high‑concentration strong‑acid or strong‑alkali environment. Please consult technical support for evaluation of special chemical‑medium working‑condition.
A: The required quantity is calculated according to system total flow rate, single‑cartridge allowable flow and raw‑water quality. Please refer to official technical datasheet for calculation, and reserve proper surplus for fluctuating‑water‑quality working scenarios.
