Cost-Efficient Big Flow Filter Element for Ultrafiltration Pre-Security Filtration

Big flow filter element, also named large diameter pleated security cartridge, is specially developed for mass water pretreatment matched with industrial ultrafiltration systems. Traditional small 2.5-inch filter cartridges need 8–12 pieces to reach the same flow of one single big flow filter element, leading to more filter housings, complicated valve pipelines and heavy daily replacement workload. Adopting 152mm outer diameter lengthened body design, big flow filter element greatly simplifies the layout of ultrafiltration front filtration station, lowers equipment investment and maintenance labor cost simultaneously.
Raw water first goes through front liquid filter to remove bulky solid impurities, then enters big flow filter element for precision interception of micro colloids, fine silt and biological flocs that easily block ultrafiltration membrane pores. We supply cross-brand replacement and self-developed original big flow filter elements to satisfy different procurement demands of ultrafiltration projects:
For replacing 3M original filter housings, choose 3M HF40PP Replacement Big Flow Cartridge
For matching Pall ultrafiltration pretreatment systems, adopt Pall HFU640 Equivalent Big Flow Filter Element
For Pentair filter tank retrofitting projects, select Pentair ALN01 Compatible Pleated Filter
For large-scale desalination & power plant ultrafiltration, deploy 60 Inch PP Industrial Big Flow Filter
The complete big flow filter element assembly includes gradient pleated filter media, reinforced PP integrated skeleton, integrated injection molded upper & lower end caps, food-grade EPDM sealing ring and anti-scratch outer protection net. Available filter media covers polypropylene, glass fiber and PTFE; precision range from 1μm to 50μm; mainstream interfaces 226 fin and flat end cap, compatible with all mainstream brand big flow filter housings on the market. All finished cartridges pass bubble point test and 72-hour hydraulic aging test before delivery to guarantee zero leakage when running with ultrafiltration equipment. Our factory supports spot shipment of cross-brand replacement cartridges and non-standard customization on length, micron rating and sealing material.
The three-stage graded filtration chain: liquid filter coarse filtration → big flow filter element precision filtration → ultrafiltration deep separation, relies on gradient folded layers to realize hierarchical interception of different-size pollutants.
Raw water with suspended impurities firstly removes large rust blocks, gravel and plastic scraps via upstream liquid filter, then flows into filter housing and penetrates from the outer folded layer inward to the central collecting tube of big flow filter element. Outer coarse filter layer traps medium particles, inner fine layer locks micro colloids, clean water converges into central pipeline and flows into ultrafiltration host for further removal of bacteria and macromolecular organics. Multi-layer gradient structure improves dirt holding capacity by 3–5 times compared with single-layer small cartridges, delaying pressure difference rise and stabilizing ultrafiltration inflow quality for weeks.
With continuous pollutant accumulation inside pleated gaps, inlet-outlet differential pressure of filter tank rises gradually. When reaching the warning value of 0.25MPa, on-site pressure gauge sends reminder signal. Delayed replacement will cause insufficient water supply for ultrafiltration, reduce membrane backwashing efficiency and accelerate membrane fouling speed.
Clean water filtered by big flow filter element can be directly used as backwash water source for ultrafiltration membrane modules. Mixing with compressed air to form gas-water mixed cleaning medium, it washes away surface pollutants of ultrafiltration membranes, extending the chemical cleaning cycle of ultrafiltration equipment by 40% under stable operation.

Q1: What economic benefits can big flow filter element bring to industrial ultrafiltration systems?
A: It drastically reduces the total number of filter cartridges and supporting filter housings, cuts initial equipment investment; longer replacement cycle and faster replacement operation lower labor and shutdown loss cost, effectively reduce the long-term comprehensive expenditure of ultrafiltration water stations.
Q2: Can your big flow filter element directly replace 3M, Pall, Pentair original filter cartridges?
A: Yes. We develop fully compatible replacement models including 3M HF40PP Replacement Big Flow Cartridge, Pall HFU640 Equivalent Big Flow Filter Element and Pentair ALN01 Compatible Pleated Filter, same dimension, flow and precision, directly installed into original filter housings without pipeline modification.
Q3: How to judge the optimal replacement time of big flow filter element?
A: Monitor the inlet and outlet differential pressure of filter housing. When the pressure difference rises to 0.25MPa, replace the element immediately to avoid insufficient water intake of ultrafiltration equipment.
Q4: Why install industrial liquid filter before big flow filter element for ultrafiltration pretreatment?
A: The upstream liquid filter intercepts large hard impurities such as gravel and rust blocks, preventing sharp particles from scratching the pleated media surface of big flow filter element, slowing down element pollution and extending its service life, further protecting downstream ultrafiltration membranes.
Q5: What water quality conditions will lead to frequent blockage of big flow filter element?
A: High turbidity raw water, failed front liquid filter, long-term overloaded flow operation and over-fine selected filtration precision will cause fast differential pressure rise and early blockage of filter cartridges.
Q6: Can multiple big flow filter elements run in parallel to supply water for extra-large industrial ultrafiltration units?
A: Fully supported. Multiple big flow filter elements installed inside one large filter housing work synchronously to provide stable ultra-large flow qualified water for heavy-duty ultrafiltration equipment, widely used in municipal desalination and power plant water treatment projects.
