Pall HFU 660GFO20H Ultipleat for Ultrafiltration Pre‑filtration
Pall HFU 660GFO20H Ultipleatis a well‑known radial‑pleated high‑flow element for industrial ultrafiltration pretreatment. This liquid filter delivers high single‑element flow rate and stable particle retention performance for heavy‑duty water‑treatment systems. It can cooperate with POV102UNPFA high flow filter cartridge and PFTM1060UHFH1 high flow filter cartridge to intercept silt, suspended solids and colloidal contaminants, offering solid upstream protection for downstream ultrafiltration membrane modules. This filter element helps water treatment operators stabilize feed‑water quality and reduce the frequency of membrane fouling.
The stable service life of ultrafiltration membrane assemblies largely depends on the quality of incoming feed water, and Pall HFU 660GFO20H Ultipleat functions as a critical consumable in this pretreatment stage. This 60‑inch large‑diameter filter cartridge adopts the classic Ultipleat radial pleated structure. Optimized pleat layout maximizes effective filtration area within limited physical dimensions, supporting outstanding high‑flow performance. Its proprietary end‑cap structure matches standard high‑flow filter housings, supporting quick installation and fast replacement during on‑site maintenance. Thanks to its high throughput per element, fewer cartridges are required to satisfy flow requirements for large‑capacity water‑treatment projects.
In real‑world water‑treatment engineering practice, system designers often combine this element with Large Flow Micro Hole Folding Water Filter Element to build multi‑stage pretreatment chains before raw water enters ultrafiltration membrane vessels. Compared with traditional small‑size filter cartridges, Pall HFU 660GFO20H Ultipleat can process far higher fluid volume for each cartridge. Fewer installed filter elements may lower housing procurement expenditure, simplify field installation work and shorten time consumed in routine filter replacement operations.
Pall HFU 660GFO20H Ultipleat uses high‑performance polypropylene filter media with excellent chemical compatibility for most neutral water‑treatment environments. Thermal‑fusion welding connects filter media and end‑caps instead of liquid glue, lowering potential risks of adhesive leaching into process water. Within recommended pressure and temperature ranges, the filter media tends to minimize fiber shedding, which may reduce scratch and contamination risks for costly ultrafiltration membranes. For EPC contractors, water‑plant operators and system integrators, Pall HFU 660GFO20H Ultipleat provides a balanced choice covering filtration performance, dimensional compatibility and project cost control.
Pall HFU 660GFO20H Ultipleat applies radial pleated depth‑filtration mechanism. Raw water flows into filter housing and reaches the outer pleated surface of the cartridge. Fluid flows radially from outer pleated layers toward inner central core through multi‑layer polypropylene filter media. Solid particles, silt, iron‑oxide sediments, colloids and suspended impurities are captured on media surface and within depth layers. Treated water flows out from central inner core and transfers onward to downstream ultrafiltration equipment.
Radial pleated structural design maximizes usable filtration area under fixed outer dimension of filter cartridge. As system continues running, trapped contaminants accumulate gradually and raise differential pressure between filter inlet and outlet. When differential pressure reaches recommended threshold, on‑site staff can perform filter replacement operations. This filtration mode relies purely on physical interception, no chemical additives are introduced into process water, and original water chemical properties will not be altered significantly.
Within a complete ultrafiltration workflow, Pall HFU 660GFO20H Ultipleat acts as front‑line protective barrier for ultrafiltration membranes. It removes most coarse pollutants in advance, reduces pollutant load accumulated on membrane surfaces and decreases particle‑scratch possibilities. When designing pretreatment sequences, users can match this cartridge with High Flow Water Filter Element to build multi‑grade graded filtration. Such configuration can further ease operating burden of ultrafiltration modules and support longer continuous system running cycles.

Every Pall HFU 660GFO20H Ultipleat filter cartridge follows standardized manufacturing workflows and multi‑step quality checkpoints. Virgin‑grade polypropylene raw materials are adopted during production to maintain stable filter‑media performance. Multiple inspection items including bubble‑point testing, pressure‑cycle evaluation and fiber‑shedding tests are carried out for finished cartridges before shipment.
Thermal‑welding technology connects filter media and end‑caps, striving for stable bonding performance under regular water‑treatment operating conditions. Dimensional inspection is completed according to housing fitting requirements. Batch‑wise production records are reserved for traceability purposes.
Sample filter units are tested under simulated industrial water‑treatment working conditions. Long‑time high‑flow cycle tests help assess structural stability under common application scenarios. Products comply with widely‑accepted industrial water‑treatment component standards. Properly selected and maintained filter elements may help reduce unexpected system downtime and bring optimized operating costs for end‑users.
Pall HFU 660GFO20H Ultipleat is mainly used for ultrafiltration system pre‑filtration protection, covering multiple industrial sectors:
Industrial Pure‑Water Production: Pre‑filtration for ultrafiltration units of electronics, food and beverage factories, intercepting silt and granular impurities to protect ultrafiltration membrane modules.
Municipal Water Reuse Project: Pretreatment for municipal reclaimed‑water ultrafiltration processes, coping with high‑volume raw water containing high content of suspended solids.
Seawater Desalination Pretreatment: Used as front‑end security filtration matched with ultrafiltration devices, lowering pollutant burden for subsequent processing steps.
Pharmaceutical & Cosmetic Process‑water System: Removing granular contaminants from process water to satisfy pretreatment requirements for preparation‑water ultrafiltration.
Mine and Industrial Wastewater Recycling: Filtering recycled wastewater before ultrafiltration recovery steps, which may reduce membrane fouling frequency.
Industrial‑park Centralized Water Supply: Pre‑filtration for large‑scale centralized ultrafiltration water‑supply systems.
Users can adjust configuration according to raw‑water quality and project budget. For heavily polluted incoming water, multi‑stage graded filtration setup is recommended to potentially extend filter service cycles. For high‑purity process‑water projects, finer‑precision filter grades can be selected.
