Pall Ultipleat High Flow Water Filter for UF Pretreatment System
Pall Ultipleat High Flow Water Filter serves as a core pretreatment component for industrial ultrafiltration equipment. This liquid filterprovides outstanding dirt‑holding capacity and helps reduce the frequency of routine cartridge replacement. Constructed with reinforced pleated filter media, it is compatible with standard large‑flow filter housings and can work alongside High‑flow water filter cartridge and Water Filtration PP Pleated Filter to build complete multi‑stage water‑treatment workflows. It is widely adopted in power, chemical, food‑beverage process water purification projects across global markets.
Pall Ultipleat High Flow Water Filter is a well‑known large‑diameter high‑flow pleated filter cartridge specially optimized for ultrafiltration front‑end protection. As a drop‑in interchange industrial filter element, it is installed on the upstream of ultrafiltration membrane modules. Its primary mission is to capture suspended solids, colloids, fine sediment, pipeline rust and granular impurities inside raw water. By removing most particulate contaminants in advance, it effectively lowers UF membrane fouling risk, cuts down chemical cleaning cycles and prolongs the service life of high‑cost ultrafiltration membrane components.
Compared with conventional small‑size filter cartridges, Ultipleat series adopts unique large‑diameter pleated structural design, which greatly expands the effective filtration area of single filter element. Under identical operating flow conditions, fewer cartridges need to be placed inside filter housing. For system integrators and end‑users, this brings practical advantages: fewer filter housings, simplified installation work and decreased long‑term operation‑maintenance expenditure. When designing a complete water‑treatment skid, users can match it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to realize multi‑grade gradient pre‑filtration interception performance.
This filter cartridge adopts advanced thermal‑bond pleating craft instead of adhesive bonding, eliminating secondary pollution risk caused by glue dissolution under long‑term water flow scouring. End caps and inner‑outer support skeletons are integrally molded, maintaining stable structural performance under continuous high‑flow impact and frequent pressure fluctuation. Whether for newly‑built ultrafiltration water‑making equipment or spare‑part replacement of existing water‑treatment production lines, Pall Ultipleat High Flow Water Filter can deliver stable and consistent pretreatment filtering performance.
Pall Ultipleat High Flow Water Filter operates on surface‑depth composite pleated filtration principle. After raw water enters filter housing, fluid flows radially inward from the outer surface of filter cartridge. Large solid particles are firstly trapped on outer pleated surface layer, while tiny fine impurities penetrate into filter medium fiber gaps and get intercepted inside material layers.
Thanks to large‑area optimized Ultipleat pleated layout, pollutants are evenly distributed across the whole filter medium, rather than accumulating only on partial local surface. This structural feature slows down differential‑pressure rising speed, maximizes dirt‑holding capacity and extends the effective service cycle of filter cartridge. When pressure difference between equipment inlet and outlet reaches preset threshold value, it means filter medium is saturated with intercepted pollutants, and operators need to replace the whole cartridge.
It serves as the front‑line protective barrier for ultrafiltration equipment. Without this pretreatment protection, raw water carrying solid particles will flow directly onto UF membrane surface. Contaminants will deposit on membrane surface, block membrane pores, accelerate membrane fouling, increase chemical cleaning frequency, and even result in irreversible membrane damage. When cooperating with PFTM11UNF high flow filter cartridge for multi‑stage combined filtration, overall stability of water‑treatment system can be further improved. It should be noted that this filter element is only used for solid‑particle interception, cannot remove dissolved ions in water, so it only undertakes pretreatment work before ultrafiltration membrane.

Every batch of Pall Ultipleat High Flow Water Filter will complete full‑process production inspection and finished‑product testing before delivery. Raw‑material incoming inspection is implemented for filter cloth, support skeleton and end‑cap raw materials to guarantee raw‑material consistency. During production process, sampling inspection is carried out for pleating amplitude, thermal‑bond strength and end‑cap sealing performance.
Finished‑product testing covers bubble‑point integrity test, cyclic pressure impulse test and water‑flow pressure drop detection. Defective products with medium crack, poor sealing and structural looseness will be fully eliminated. Glue‑free thermal‑bond process avoids adhesive dissolution risk which would contaminate process water.
Products are manufactured in accordance with industrial filtration quality‑management specifications. Each filter cartridge is individually packed to prevent dust and particle contamination during storage and transportation. Complete technical datasheets are provided for engineering design reference. On‑site installation inspection is still required before putting into operation to confirm housing interface matching and sealing condition.
Pall Ultipleat High Flow Water Filter is mainly used as pretreatment filter for ultrafiltration water‑treatment systems, and it is also widely deployed in multiple industrial liquid‑filtration scenarios.
Industrial ultrafiltration system pretreatment: Trap sediment, iron‑oxide scale and suspended particles, protect UF membrane elements, reduce membrane cleaning frequency, suitable for raw‑water purification and circulating‑water treatment projects.
Power plant water treatment: Boiler make‑up water and condensate pre‑filtration, remove pipeline rust particles and suspended pollutants.
Food & beverage industry: Raw‑water pretreatment for drinking‑water and beverage production, filter granular impurities.
Chemical industry: Production process‑water filtration and circulating cooling‑water pretreatment.
Municipal water‑supply & reclaimed‑water reuse: Large‑flow raw‑water pre‑filtration for municipal water‑works and water‑recycling projects.
Pharmaceutical and cosmetic water‑making: Sanitary‑grade process‑water pre‑filtration for water‑preparation equipment.
According to actual raw‑water turbidity and pollutant composition of different projects, users can set multi‑stage gradient filtration to achieve better overall filtering effect.
A: It acts as ultrafiltration pretreatment protective filter. It intercepts suspended solids, sediment and granular contaminants inside raw water, reduces pollutant load on ultrafiltration membranes, slows down membrane fouling, cuts chemical‑cleaning frequency and extends UF membrane service life.
A: There is no fixed service‑life time standard. Service cycle is mainly determined by raw‑water turbidity, pollutant content and actual operating flow. Normally replace cartridge when inlet‑outlet differential pressure reaches 0.35 MPa.
A: This is disposable pleated filter element. After filter‑medium gaps are filled with pollutants, backwashing cannot fully restore original filtering performance. Re‑use after cleaning will bring particle leakage risk, direct replacement is recommended.
A: It adapts to 40‑inch /60‑inch large‑flow filter housing with special Ultipleat connection interface. Before purchase, please confirm housing interface dimension, inner‑chamber space and pressure‑bearing rating to avoid installation mismatch.
A: Polypropylene material has good tolerance for weak‑acid and weak‑alkali aqueous medium. It is not fit for long‑term operation under high‑concentration strong‑acid or strong‑alkali environment. Please consult technical support for evaluation for special chemical‑medium working conditions.
A: Quantity calculation depends on system total flow rate, single‑cartridge allowable flow and raw‑water quality. It is suggested to calculate required quantity referring to technical datasheet, and properly reserve surplus for fluctuating‑water‑quality working scenarios
