60 Inch High Flow Filter Cartridge for Ultrafiltration Pre-treatment
This article focuses on the 60 inch high flow filter cartridge, the longest and highest-capacity pre-filter element for large-scale ultrafiltration water treatment systems. A liquid filterengineered with deep pleated polypropylene media, it efficiently removes suspended solids, colloids and particulate contaminants to protect downstream UF membrane modules. Our 60 inch high flow filter cartridge can replace Equivalent ALN01-60B High Flow Cartridge for Ultrafiltration, widely applied in seawater desalination, industrial wastewater reuse and power plant condensate polishing projects. With the largest single-element flow rate and dirt holding capacity, it minimizes the quantity of filter housings and reduces maintenance frequency for full-scale water treatment plants.
The 60 inch high flow filter cartridge is the longest pleated industrial filter element specially designed for large-scale and extra-high-capacity ultrafiltration pretreatment systems. Among all specifications of the high flow filter series, this 60 inch high flow filter cartridge delivers the largest single-cartridge flow rate and the biggest dirt holding capacity, which makes it the preferred pre-filter solution for full-size UF water treatment plants. Compared with 20-inch compact models and 40-inch standard variants, the 60 inch high flow filter cartridge requires far fewer filter vessels to reach the same treatment capacity, significantly reducing equipment footprint, pipeline investment and long-term maintenance labor.
This filter cartridge is fully interchangeable with High Flow Cartridge Filter Element for Ultrafiltration Pre-treatment, and compatible with the structure and sealing standards of Pre-filtration Filter Cartridge for Industrial Ultrafiltration Systems. Installed right before ultrafiltration membrane racks, the 60 inch high flow filter cartridge intercepts sediment, rust particles, algae, fine silt and organic fragments contained in raw inlet water. Without effective prefiltration protection, solid impurities will scratch the UF membrane surface, block membrane pores and lead to irreversible membrane fouling. Serious fouling will continuously lower membrane permeate flux, increase chemical cleaning cycles and shorten the service lifespan of expensive ultrafiltration membrane elements. For projects that need higher filtration precision, customers can also refer to High Flow Series Filter Element for Industrial Ultrafiltration as a compatible alternative solution.
The 60 inch high flow filter cartridge features a reinforced polypropylene inner core and outer support cage, which can endure fluctuating differential pressure under long-term continuous running conditions. Gradient-density polypropylene pleated filter media provides high dirt holding capacity while maintaining low initial pressure drop. Multiple micron grades from 1μm up to 100μm are available to adapt to different raw water turbidity and impurity characteristics. EPDM, silicone and Viton sealing gaskets are optional to fit different liquid temperature and chemical compatibility requirements. It has become the standard security pre-filter for large ultrafiltration systems in many industrial water treatment sectors.
The 60 inch high flow filter cartridge operates on the pleated depth filtration principle, combining surface sieve effect and deep adsorption interception. Raw water flows radially from the outer pleated surface of the filter cartridge, penetrates the 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 such as sand grains, rust debris and plankton are trapped on the outer pleated layer. Fine colloids and tiny suspended particles are captured inside the gradient filter layers. The gradient density design allows pollutants to distribute evenly inside the filter media instead of accumulating only on the outermost surface. This special design maximizes dirt holding capacity and extends the filter service cycle, avoiding rapid pressure rise after a short operation time.
In the complete ultrafiltration pretreatment workflow, the 60 inch high flow filter cartridge serves as the critical protective barrier for ultrafiltration membranes. It stabilizes the Silt Density Index (SDI) of inlet water and reduces the particulate load entering UF membrane modules. When the differential pressure between inlet and outlet reaches the preset threshold, the filter cartridge needs to be replaced. The extra-long 60-inch element reduces the total number of cartridges and housings, making system procurement, stocking and replacement much easier for engineering and maintenance teams.

All parameters are tested under standard laboratory environments. Actual flow rate and dirt holding capacity will be affected by raw water turbidity, liquid temperature and impurity concentration. Our engineering team can customize micron rating, end cap connection and gasket material according to your on-site ultrafiltration project requirements.
All 60 inch 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, pressure resistance test and full visual inspection before shipment.
Automated pleating equipment ensures consistent pleat density for each filter element, guaranteeing stable flow performance 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 equivalent filtration performance as famous brand cartridges, with better overall cost performance. Our products are fully tested to prevent media shedding, which is essential to avoid secondary contamination to ultrafiltration membrane modules.
This is the core application. The 60 inch high flow filter cartridge acts as the security filter before ultrafiltration membrane racks in municipal water treatment and large industrial water reuse projects. It removes particles and colloids, stabilizes inlet SDI, protects UF membranes and reduces chemical cleaning frequency.
For chemical, petrochemical, food and beverage wastewater recycling projects, it works as the pre-filter for ultrafiltration systems, lowering pollutant load and improving system water recovery rate.
In large desalination plants, this filter cartridge filters raw seawater, intercepts sea sand, algae and suspended solids, to protect ultrafiltration and reverse osmosis membranes in the pretreatment skid.
Power plants use the 60 inch high flow filter cartridge for condensate polishing systems, removing iron oxide and particulate impurities, protecting boiler and downstream membrane equipment.
Municipal water plants adopt this filter cartridge in UF water purification process, removing suspended impurities in raw river or lake water to extend ultrafiltration membrane service life.
A: It works as the key security pre-filter for ultrafiltration systems. It intercepts suspended particles, silt and colloids, reduces SDI value of incoming water, prevents fouling and mechanical scratch damage to ultrafiltration membranes, and extends the service life of UF modules.
A: It is longer and delivers a higher single-element flow rate with a larger dirt holding capacity. For the same water throughput, far fewer filter cartridges and filter housings are required, saving equipment investment and maintenance labor cost.
A: Yes. Polypropylene media has good salt tolerance. We can select matched sealing gaskets according to your seawater salinity and temperature. You can send your water quality report for our professional compatibility assessment.
A: 5μm or 10μm are the most popular options for ultrafiltration pretreatment. If raw water contains a large amount of coarse sediment, 20μm or 40μm is recommended. Our technical team will provide customized suggestions based on your water test data.
A: Replacement cycle depends on raw water impurity load. Normally, replace the cartridge when the inlet-outlet differential pressure reaches 2.5 bar. In general industrial water projects, its service life ranges from 1 to 3 months.
A: Yes. We support custom end cap connection styles and multiple gasket materials including EPDM, silicone and Viton to fit your existing filter housing and working medium.
