Pleated High Flow Filter for Industrial Ultrafiltration Systems
Pleated High Flow Filter is a widely adopted consumable in industrial ultrafiltration pretreatment and large-scale liquid purification projects. This liquid filter maximizes filtration area through folded media design to achieve large throughput with low pressure drop. Our HFU640UY045JUW high flow filter cartridge belongs to this product series, which can effectively protect ultrafiltration membranes and seawater reverse osmosis element from particulate contamination. Our pleated high flow filters are manufactured with premium filter media, offering reliable particle retention performance and long service cycles for water treatment, chemical, power and seawater desalination industries.
Product Introduction
Pleated High Flow Filter is a kind of large-capacity filter cartridge with pleated filter media, commonly installed inside filter housings as the front pretreatment unit of ultrafiltration equipment. Traditional filter cartridges have limited filtration area, requiring dozens of cartridges to handle large liquid flow. The pleated structure of Pleated High Flow Filter greatly expands the effective filtration surface area within one single cartridge. It can deliver high liquid flow rate while keeping low differential pressure, which reduces the total quantity of filter elements required in the system, saving installation space, cutting inventory cost and simplifying routine maintenance work. Our High-Flow Pod Filter is the classic pleated high flow filter product, designed for industrial water pretreatment before ultrafiltration systems.
In a complete ultrafiltration water treatment workflow, raw water usually carries sediment, algae, suspended solids, colloids and large organic particles. Without proper pre-filtration, these impurities will directly scour and block ultrafiltration membrane modules, causing irreversible membrane fouling and shortening membrane service life. Pleated High Flow Filter acts as the first defensive line to trap these large pollutants. For raw water with high turbidity, we can also equip Glass Fiber Filter Cartridge as secondary filtration to further reduce feed water SDI value and stabilize the running status of ultrafiltration equipment.
We supply multiple types of pleated high flow filters with different filter media, including polypropylene, glass fiber and composite media. Different end cap designs and sealing options are available to match most standard industrial filter housings. Our pleated high flow filter can also be used as replacement elements for mainstream brand housings, such as our Pall Ultipleat High Flow Element replacement version. Whether for small skid-mounted ultrafiltration devices or large centralized industrial water treatment stations, pleated high flow filter can be configured to meet customized flow and precision requirements.

Working Principle
The working principle of Pleated High Flow Filter relies on surface filtration and depth filtration based on folded filter media. Raw liquid flows into the filter housing and enters from the outer wall of the pleated high flow filter cartridge. As the liquid passes through the multi-layer folded filter media, solid particles, colloids and impurities are captured on the surface and inside the pores of filter media. The purified liquid flows into the inner core of the cartridge and flows out from the outlet of filter housing.
The pleated design is the core advantage of this filter. By folding flat filter media into dense wrinkles, the usable filtration area increases many times compared with non-pleated filter cartridges of the same length. Larger filtration area means higher liquid throughput and slower pressure difference rise during operation, which is the key reason Pleated High Flow Filter is widely used for ultrafiltration pretreatment.
When integrated with ultrafiltration equipment, the full treatment sequence is raw water intake → Pleated High Flow Filter pre-filtration → ultrafiltration membrane separation → advanced treatment. The pre-filter removes large contaminants in advance, so only tiny micro-particles can reach the ultrafiltration membrane. Our Replace Pall Water Filter Element adopts the same pleated high flow filtration principle. Operators monitor the inlet and outlet pressure difference. When the differential pressure rises to the preset threshold, the pleated high flow filter cartridge needs replacement to recover filtration performance and protect downstream ultrafiltration membranes.

The selection of Pleated High Flow Filter parameters should be determined by raw water quality and ultrafiltration system design. Higher filtration precision will reduce the maximum flow rate, so we balance flow capacity and retention accuracy for each project. Our Equivalent Pall Filter HFU660GF060H13 shares the same technical specifications and can directly replace original filter elements without modifying filter housings.
Quality Control
Every Pleated High Flow Filter undergoes strict multi-step quality control during production. Raw filter media will be tested for bubble point, tensile strength and chemical compatibility before pleating and assembly. After folding, thermal welding and end cap bonding, each finished pleated high flow filter will carry out bubble point leak detection one by one, to check for pinholes, media damage and sealing defects.
We follow ISO industrial filtration manufacturing standards for batch production. Material certificates, batch test reports and bubble point inspection records can be provided for project bidding and factory audit. Accelerated fouling simulation tests are performed in our factory to verify long-term stability of pleated high flow filter under real industrial operating conditions.
Our professional technical team offers full-cycle support, including system flow calculation, filter housing selection, installation guidance and maintenance training for pleated high flow filter and ultrafiltration systems. We also provide after-sales consultation about cartridge replacement, pressure difference monitoring and membrane protection solutions.
