Large flow micro hole folding water filter element adopts multi-layer micro porous membrane folding process, which is the core pretreatment component matched with tubular, hollow fiber ultrafiltration equipment in industrial water treatment pipelines. Compared with traditional ordinary filter cartridges, uniform dense micropores on the folded layer realize graded interception of tiny impurities, while the large-diameter body realizes large-volume water passing capacity, greatly cutting the number of filter vessels configured before ultrafiltration equipment and simplifying the pipeline layout of the whole water treatment skid. After the raw water is coarsely filtered by the front liquid filter, the micro-hole folding filter element performs precision secondary filtration, intercepting tiny pollutants that easily block ultrafiltration membranes, prolonging the chemical cleaning cycle of ultrafiltration modules and reducing the loss rate of ultrafiltration membranes.
We supply serialized large-flow micro-hole folding filter products to adapt to different working conditions of ultrafiltration equipment for global clients. For conventional ultrafiltration front-end safety protection, select HF60 High Flow Filter Cartridge for Industrial Security Filtration; for industrial process liquid and production water supporting filtration, adopt HF20 S 3M High Flow Water Filter Cartridge for Industrial Liquid; for factory circulating water pretreatment matched with ultrafiltration devices, choose HDX4PF4 High Flow Water Filter Cartridge for Industrial Water; for conventional standardized ultrafiltration supporting projects, use general High Flow Filter Element; for petrochemical wastewater ultrafiltration pretreatment, match Powering Petrochemical Progress: The Superiority of High-Flow Filter; for integrated intelligent water treatment equipment, deploy High-Flow Filter Cartridges: The Engine for Uninterrupted Filtration.
A complete filter assembly consists of micro-hole folded filter media, reinforced PP supporting skeleton, multi-layer microporous structure, EPDM sealing ring, stainless steel filter housing and front liquid filter. The filter media material is optional PP, PTFE and glass fiber, the micropore precision ranges from 1μm to 50μm, and the interface adopts mainstream 226 fin and flat opening structure, compatible with most domestic and imported filter tanks. All finished products pass bubble point integrity test and hydraulic sealing test before delivery to ensure no leakage during the coordinated operation with ultrafiltration equipment. Our factory supports mass spot delivery and personalized non-standard customization, and can provide complete test reports to help customers complete project acceptance and customs clearance smoothly.
The micro-hole folding filter element, front liquid filter and post ultrafiltration equipment form three-level progressive water purification system: coarse filtration → micropore precision filtration → ultrafiltration deep purification, relying on physical interception, inertial sedimentation and micropore adsorption to purify water fluid.
Original industrial wastewater or raw water first removes large sundries through the front liquid filter, then enters the filter housing and penetrates from the outer folded wall with dense micropores to the central inner cavity of the filter element. Fine particles, colloids and tiny organic matter are trapped in the multi-layer microporous structure, and the purified water converges into the central pipeline and flows into the ultrafiltration host for further removal of macromolecular organics, bacteria and microorganisms. The folded micropore structure increases the contact area between water flow and filter material, maintaining stable large flow rate under low differential pressure and stabilizing the water inflow quality of ultrafiltration equipment.
With the accumulation of intercepted pollutants in the microporous layer, the pressure difference between the inlet and outlet of the filter tank will gradually rise. When the pressure difference reaches 0.25MPa warning value, the field pressure gauge will send out an alarm. If the filter element is not replaced in time, the pipeline flow resistance will increase sharply, reduce the water supply of ultrafiltration equipment, and even cause pump overload shutdown.
Glass fiber and PTFE micro-hole folding filter elements can be regenerated by regular reverse clean water backwashing to wash away surface intercepted dirt and restore partial filtering flux. Disposable PP microporous filter elements need to be replaced directly after pressure difference exceeds the standard value to guarantee the continuous and stable operation of the ultrafiltration system.

Q1: What is the protective effect of large flow micro hole folding water filter element on ultrafiltration equipment?
A: The uniform microporous folded structure intercepts fine impurities that are easy to adhere to ultrafiltration membranes, reduce membrane fouling speed, extend the service life of ultrafiltration membrane elements, and reduce the frequency of chemical cleaning of ultrafiltration equipment.
Q2: Can HF60, HF20 and HDX4PF4 filter elements customize micropore precision and overall size?
A: Yes. Our technical team can adjust micropore aperture, filter length and sealing material according to customer water quality data, pipeline flow and existing ultrafiltration parameters to realize accurate system matching.
Q3: What is the conventional replacement cycle of PP micro-hole folding filter element in water pipelines?
A: For clean circulating water, the replacement cycle is 2–3 months; if the raw water contains a lot of sediment and impurities, the pressure difference rises rapidly, and replacement is required within one month.
Q4: Why configure liquid filter in front of micro-hole folding filter element?
A: The front liquid filter blocks large particles such as rust blocks and gravel, prevents hard sundries from scratching the surface microporous structure of the folding filter element, slows down the pollution speed of the filter element, and reduces the overall maintenance cost of the ultrafiltration system.
Q5: What factors will cause premature blockage of micro-hole folding filter elements?
A: Excessive impurity content in inlet water, failure of front liquid filter, long-term overload water flow operation and too small selected micropore precision will lead to rapid pressure difference rise and early blockage.
Q6: Can multiple micro-hole folding filter elements be installed in parallel to supply water for large ultrafiltration equipment?
A: Parallel installation inside a single filter tank is fully supported. Multiple filter elements work together to provide stable large-flow inlet water for large industrial ultrafiltration units, which is widely used in centralized water treatment projects.
