Membrane Filter Cartridge for Industrial Ultrafiltration Pretreatment
Membrane Filter Cartridge is a precision consumable for ultrafiltration pretreatment systems. This liquid filter captures fine particulates and colloids to protect UF membrane modules from fouling and damage. It provides reliable fine filtration performance for diverse industrial water and liquid purification projects.
Membrane Filter Cartridge is a precision microporous membrane filter element, widely used as the primary pretreatment consumable for industrial ultrafiltration equipment. Raw water extracted from wells, rivers, seawater and recycled wastewater contains suspended solids, colloids, algae and tiny particulate contaminants. Without effective pre-filtration, these impurities will adhere to the surface of ultrafiltration membranes, block membrane pores, abrade the membrane surface, and cause irreversible decline in water yield and treatment efficiency. Membrane Filter Cartridge serves as the critical front-line barrier to remove fine pollutants before fluid enters ultrafiltration membrane modules.
Our membrane filter cartridge series uses polypropylene membrane as the core filter medium, with deep pleated construction to maximize available filtration area. Multiple filtration ratings are available to match different raw water quality requirements. When designing multi-stage ultrafiltration pretreatment workflows, customers can select Pall Ultipleat High Flow Filter HFU640UY045H equivalent replacement cartridges to build graded filtration schemes. The large-diameter membrane filter cartridge adopts outside-in fluid flow path. Thanks to the pleated membrane structure, a single membrane filter cartridge can handle a much higher flow rate than traditional small filter cartridges, which reduces the total number of filter housings required, saves installation space and lowers spare parts management costs for water treatment plants.
A complete ultrafiltration pretreatment assembly includes filter pressure vessel, membrane filter cartridges, pressure gauges, regulating valves and connecting pipelines. Filter housings are usually made of stainless steel or epoxy-coated carbon steel. The end caps of membrane filter cartridges adopt thermal fusion welding without adhesive, eliminating the risk of glue dissolution and secondary liquid contamination. An integrated lifting handle on the top simplifies cartridge replacement. Operators can finish disassembly and installation rapidly without direct contact with contaminated membrane media, avoiding secondary liquid pollution during maintenance. Membrane Filter Cartridge maintains low pressure drop, high dirt holding capacity and stable filtration performance under 24-hour continuous operation, reducing system downtime and labor maintenance costs for the whole ultrafiltration water treatment system.
The working principle of Membrane Filter Cartridge is surface and depth composite membrane filtration for ultrafiltration pretreatment. Raw liquid flows into the filter housing and fills the inner cavity of the pressure vessel. The fluid follows the outside-in flow path, passing through the outer pleated membrane surface and moving inward toward the central hollow support core. Larger particles like silt and plankton are trapped on the outer pleated layers, while fine colloids, tiny suspended particles and partial microorganisms are intercepted by the microporous membrane structure. Clarified liquid flows through the inner core and enters downstream ultrafiltration membrane equipment.
The pleated membrane structure greatly expands the effective filtration area within limited cartridge dimensions. The expanded membrane surface evenly distributes contaminant load and slows the rising rate of differential pressure during continuous running. The uniform micropore structure of the membrane filter ensures stable particle interception efficiency. Unlike ordinary depth filter cartridges, membrane filter cartridges have well-defined pore size, achieving more precise cutoff of fine particles.
On-site technicians monitor the pressure difference between filter inlet and outlet in real time. When differential pressure reaches the preset threshold, the Membrane Filter Cartridge has reached its maximum pollutant holding capacity and needs timely replacement. Delayed replacement will lead to membrane rupture, and trapped solid particles will break through the filter layer, scratching the ultrafiltration membrane surface and causing permanent damage. As the front pretreatment safety barrier of ultrafiltration equipment, membrane filter cartridges reduce particle load entering membrane modules, stabilize water yield and treated water quality, and decrease the frequency of chemical cleaning for membrane components.

All technical indicators of Membrane Filter Cartridge are verified in our professional filtration laboratory. If you need to customize a complete ultrafiltration pretreatment skid according to raw water quality, you can view our PFTM12UEPFB high flow filter cartridge series to configure multi-stage filtration combinations matching different working conditions.
Strict quality control covers the whole manufacturing workflow of Membrane Filter Cartridge. Raw material inspection is the first checkpoint. Microporous membrane, inner support core and end cap raw materials are tested for tensile strength, temperature resistance and chemical compatibility. Any inferior raw materials that cannot adapt to industrial liquid environments will be rejected before production. Before pleating, filter membrane will pass bubble point testing to verify pore size accuracy and membrane integrity.
During mass production, automatic pleating equipment ensures uniform pleat depth and density for every membrane filter cartridge. After thermal welding of end caps, each finished filter cartridge undergoes 100% integrity inspection. Bubble point testing detects membrane cracks or sealing leakage, to ensure unfiltered raw liquid cannot bypass the filter element. Aging and pressure cycle tests are carried out in our lab to simulate long-term industrial operating environments. Test samples repeatedly endure fluctuating pressure and temperature to validate structural stability and sealing reliability.
Our factory runs under ISO 9001 quality management standards. Complete test records are archived for each production batch. Material certificates and filtration performance reports can be supplied upon client request. All products are adhesive-free and free of fiber shedding, avoiding secondary liquid pollution. Our quality benchmarks match international industrial filter standards, making Membrane Filter Cartridge dependable pretreatment consumables for ultrafiltration systems.
