1 Micron High Flow Filter Cartridge for Ultrafiltration Pre-treatment
This article focuses on the 1 micron high flow filter cartridge, a fine-grade high flow filter designed for critical ultrafiltration pretreatment in industrial water treatment. A liquid filter constructed with pleated polypropylene media, it delivers precise 1μm particle retention and excellent dirt holding capacity to fully protect downstream UF membrane modules. Our 1 micron high flow filter cartridge can replace High Flow Pleated Liquid Filter Cartridge HFU660UY060J for UF, widely applied in power plant condensate polishing, pure water production and industrial wastewater reuse projects. Its 1 micron fine filtration rating efficiently intercepts tiny suspended solids and colloids, stabilizing feed water SDI and lowering the risk of irreversible fouling on ultrafiltration membranes.
The 1 micron high flow filter cartridge is a fine precision pleated high flow filter element, specially developed to serve as the security pre-filter for high-demanding ultrafiltration water treatment systems. Compared with 5μm,10μm coarse high flow filter cartridges, this 1 micron high flow filter cartridge provides finer particle interception performance, targeting tiny silt, fine colloids and micro-organisms that threaten the integrity of UF membranes. It adopts the classic high flow outer-to-inner radial flow structure, available in multiple lengths such as 20”,40”,60”, to match different filter housings for small UF skids and large full-scale industrial water plants.
This filter cartridge is fully interchangeable with Big Flow Rate Filter Cartridge for Ultrafiltration Pretreatment, and matches the sealing and connection specifications of High Flow Liquid Filter for Industrial Ultrafiltration Systems. Installed right before ultrafiltration membrane racks, the 1 micron high flow filter cartridge removes micro particulate contaminants from raw feed water. Without fine prefiltration protection, tiny hard particles and colloidal substances will stick to or scratch the surface of ultrafiltration membranes, clog membrane pores and lead to permanent membrane fouling. Once severe fouling occurs, the membrane flux will keep declining, chemical cleaning cycles will increase, and the service life of expensive UF membrane modules will be shortened significantly. If your project needs other micron grades of high flow pre-filter for UF pretreatment, Pleated High Flow Filter for Industrial Ultrafiltration Systems is another reliable alternative product to consider.
The 1 micron high flow filter cartridge is built with reinforced polypropylene inner core and outer support cage, which can withstand fluctuating differential pressure under long-term continuous running. The gradient-density pleated polypropylene media achieves 1 micron absolute filtration efficiency, while maintaining a relatively low initial pressure drop. The gradient structure helps distribute captured pollutants evenly inside the filter media instead of blocking only the outer surface. EPDM, silicone and Viton sealing gaskets are optional to adapt to different liquid temperature and chemical compatibility requirements. Even with the fine 1μm rating, the high-flow pleated design ensures high single-element flow rate, reducing the required number of filter cartridges and housings for your ultrafiltration pretreatment skid.
The 1 micron high flow filter cartridge operates based on pleated depth filtration principle, combining surface screening and deep adsorption interception. Raw water flows radially from the outer pleated surface of the filter cartridge, penetrates multi-layer graded polypropylene media, purified liquid flows inward through the central inner core and exits from the end port of the filter element.
Large contaminants like sand grains and rust debris are trapped on the outer pleated layer. Fine colloids, micro silt and tiny suspended particles down to 1 micron are captured inside the gradient filter layers. The gradient density design allows pollutants to distribute evenly inside the filter media rather than accumulating only on the outermost surface. This design maximizes dirt holding capacity and extends the filter service cycle, avoiding rapid pressure rise after a short operation period.
In the ultrafiltration pretreatment workflow, the 1 micron high flow filter cartridge acts as the critical final barrier before the UF membrane system. It reduces the Silt Density Index (SDI) of inlet water and minimizes the particulate and colloidal load entering ultrafiltration membrane modules. When the differential pressure between inlet and outlet reaches the preset threshold, the filter cartridge needs replacement. The high flow design reduces cartridge quantity, simplifying inventory management and filter replacement work for on-site maintenance teams.

All 1 micron high flow filter cartridge products are manufactured under ISO9001 quality management system. Raw filter media will be strictly inspected before production to check pinholes, uneven thickness and material defects. Every finished filter cartridge will go through bubble point integrity test, particle retention efficiency test, pressure resistance test and full visual inspection before shipment.
Automated pleating equipment ensures consistent pleat density for each filter element, guaranteeing stable 1μm filtration efficiency and dirt holding capacity. Reinforced inner core prevents media collapse under variable operating pressure, which is a common failure mode of low-cost filter cartridges. All filter cartridges are cleaned and packed in dust-free workshop to avoid secondary contamination before delivery.
We provide batch inspection reports for each order. Third-party material testing can be arranged upon customer request. Our replacement filter elements deliver stable filtration performance, with good cost performance. Our products are fully tested to prevent media shedding, which is essential to avoid secondary contamination to ultrafiltration membrane modules.
