Product Introduction

High Capacity Pleated Cartridges are large diameter filter elements built for high throughput and high dirt holding capacity, commonly deployed in the pretreatment stage of industrial ultrafiltration water treatment equipment. The deep pleated media design dramatically expands the effective filtration surface area of a single cartridge, allowing it to handle much higher liquid volume than traditional small-diameter filter cartridges. The standard filter media adopts virgin polypropylene material, with a full range of micron ratings from 0.5 micron up to 100 micron, to match diverse raw water turbidity and contaminant compositions. Installed on the upstream side of ultrafiltration membrane modules, High Capacity Pleated Cartridges intercept silt, iron rust, suspended solids and colloidal pollutants before raw water enters expensive UF membranes. Regular replacement of these cartridges prevents irreversible scratches and pore blockage on membranes, extends the service life of ultrafiltration membranes, reduces chemical cleaning cycles and cuts the overall maintenance workload of the water treatment system.

The core competitive advantage of High Capacity Pleated Cartridges lies in their outstanding contaminant holding capacity. The densely folded filter media can accumulate far more trapped particles before reaching the differential pressure threshold, extending service cycles and reducing cartridge replacement frequency. Thanks to the large outer diameter design, fewer cartridges are required inside filter housings. This reduces the overall footprint of the filtration skid, lowers spare parts inventory expenditure and simplifies on-site filter replacement work, minimizing production downtime during maintenance. When designing complete prefiltration systems, engineers can pair High Capacity Pleated Cartridges with PFTM11UNPFA high flow filter cartridge and HFU640HGF100H1 high flow filter cartridge to build gradient multi-stage raw water filtration systems.

High Capacity Pleated Cartridges adopt glue-free thermal fusion sealing technology. Filter media, inner support core, outer protective skeleton and end caps are thermally bonded into one integrated structure. This manufacturing process eliminates the risk of adhesive dissolution and secondary liquid contamination under long-term continuous water flushing. Virgin polypropylene raw material brings excellent chemical inertness and low fiber shedding rate. Whether customers are constructing brand-new ultrafiltration pretreatment systems or maintaining existing water reuse facilities, High Capacity Pleated Cartridges maintain reliable filtration performance and can serve as cost-effective drop-in replacements for many well-known branded high flow filter elements.

Working Principle

High Capacity Pleated Cartridges operate through a combination of surface filtration and depth filtration mechanisms. Raw water flows radially inward from the outer pleated surface of filter media, penetrating through multi-layer folded fiber webs. Large impurities such as sediment and rust deposits are captured on the outer pleated surface of filter media. Fine colloids and micro suspended particles penetrate into the fiber layers and get trapped inside the gaps of the fiber structure.

The deep pleated design maximizes usable filtration area for each High Capacity Pleated Cartridge, distributing pollutant loads evenly across the whole filter media surface. This slows down surface clogging, delays the rise of differential pressure between filter inlet and outlet, and greatly improves 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 High Capacity Pleated Cartridges.

These filter cartridges form the primary protective barrier for ultrafiltration membranes. Without effective 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 High Capacity Pleated Cartridges can only remove solid particulate pollutants. They cannot remove dissolved ions and soluble salts, and only provide mechanical prefiltration protection before ultrafiltration membrane units.

Technical Parameters

Quality Control

Every batch of High Capacity Pleated Cartridges undergoes full-process production 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, which meets the strict water quality requirements of industrial pretreatment projects.

All products comply with strict industrial filtration quality management standards. Each High Capacity 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.

Application Fields

High Capacity Pleated Cartridges are widely used as pretreatment filter elements for ultrafiltration water treatment systems, also suitable for various industrial liquid filtration scenarios.

1. Industrial ultrafiltration system pretreatment: Intercept fine suspended particles, silt and colloids, protect UF membrane elements, reduce membrane fouling and chemical cleaning frequency. Suitable for raw water purification and industrial wastewater reuse projects.

2. Power plant water treatment: Pre-filtration for boiler feed water and condensate water, removing fine suspended particulate impurities.

3. Seawater desalination industry: Prefiltration protection for ultrafiltration units in desalination plants.

4. Chemical industry: Process liquid filtration and circulating cooling water pretreatment for chemical production lines.

5. Municipal water reuse: Large-flow raw water prefiltration for municipal wastewater recycling plants.

6. Oil & gas produced water treatment: Pre-filter solid impurities before ultrafiltration of oilfield produced water.

System designers can configure multi-stage gradient filtration scheme according to raw water pollutant composition and turbidity of each individual project to optimize overall filtration efficiency.
