Product Introduction

Pall High Flow pleated cartridge is a large-diameter, high dirt-holding pleated filter element, designed specifically for the pretreatment stage of industrial ultrafiltration water treatment equipment. The deep pleated media design greatly expands the effective filtration surface area within a single cartridge body. It is widely adopted in water treatment plants where high volumetric flow and stable particle retention performance are required. The standard media selection is virgin polypropylene pleated fiber, with a broad range of micron grades from 0.5 micron to 100 micron, adapting to diverse raw water turbidity and pollutant compositions. Installed on the upstream side of ultrafiltration membrane modules, Pall High Flow pleated cartridge intercepts silt, iron oxide rust, suspended solids and colloidal contaminants before raw water enters UF membranes. Proper use and periodic replacement of this filter element minimizes irreversible membrane damage, extends membrane service life, and cuts down chemical cleaning frequency and overall system maintenance workload.

The most prominent feature of the Pall High Flow pleated cartridge is its outstanding single-element flow capacity. Its oversized diameter and densely folded filter media allow each cartridge to handle substantially higher liquid flow than traditional 2.5-inch small diameter filter cartridges. This reduces the total number of filter elements installed inside filter housings, saving space for the whole filtration skid, reducing spare parts inventory investment and simplifying on-site filter replacement work. Many water treatment operators select compatible replacement cartridges to reduce operational costs without sacrificing filtration performance. When designing full water treatment systems, engineers can match Pall High Flow pleated cartridge with PFTM11UNPFA high flow filter cartridge and HFU640HGF100H1 high flow filter cartridge to build gradient multi-stage prefiltration systems.

Pall High Flow pleated cartridge uses thermal fusion sealing technology instead of adhesive bonding. Filter media, inner support core, outer protective skeleton and end caps are thermally integrated. This glue-free production method eliminates the risk of adhesive dissolution and secondary liquid contamination under long-term continuous water scouring. Virgin polymer raw materials bring excellent chemical inertness and low fiber shedding rate. Whether maintaining existing ultrafiltration facilities running with original Pall filters, or preparing spare filters for newly commissioned wastewater reuse projects, Pall High Flow pleated cartridge maintains consistent filtration performance and proven reliability after years of on-site operation.

Working Principle

Pall High Flow pleated cartridge works by combining surface filtration and depth filtration mechanisms. Raw water flows radially inward from the outer pleated surface, penetrating through multi-layer folded fiber web. Large-sized impurities like sediment and rust deposits are captured on the outer surface of the pleated media. Fine colloids and micro suspended particles penetrate the fiber layers and get trapped inside fiber gaps.

The deep pleated structure maximizes usable filtration area for each cartridge, distributing pollutant loads evenly across the filter media. This slows surface clogging, delays the rise of inlet-outlet differential pressure and improves the dirt holding capacity. When pressure difference between inlet and outlet reaches the preset threshold, filter media becomes saturated with intercepted contaminants, and site operators need to shut down the system and replace the Pall High Flow pleated cartridge.

This filter cartridge serves as the primary protective barrier for ultrafiltration membranes. Without qualified upstream prefiltration, fine solid particles in raw water may scratch membrane surfaces, block membrane pores and lead to permanent 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 greatly enhanced. It should be noted that Pall High Flow pleated cartridge can only remove solid particulate pollutants. It cannot remove dissolved ions and only provides mechanical prefiltration protection before ultrafiltration membrane units.

Technical Parameters

Quality Control

Original Pall High Flow pleated cartridge and its compatible replacement elements undergo full-process inspection and finished-product performance testing before shipment. Raw material inspection is performed for filter media, support cores and end caps to guarantee stable batch-to-batch quality consistency. During manufacturing, sampling inspections cover pleating uniformity, medium tensile strength, thermal sealing integrity and end cap bonding performance.

Finished product tests include bubble point integrity test, cyclic pressure impulse test, flow pressure drop test and particle retention efficiency test. 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. The filter medium maintains stable structure and low fiber shedding rate under continuous liquid flushing.

All products comply with strict industrial filtration quality management standards. Each Pall High Flow pleated cartridge is individually packaged to avoid dust and particle contamination during storage and transportation. Complete technical datasheets and dimension drawings are supplied for engineering design, spare part BOM creation and quotation reference. Before installation, technicians should inspect the O-ring and filter interface to ensure perfect sealing and prevent bypass leakage.
