ALN05-60B High Flow Filter Cartridge for UF Pretreatment
ALN05-60B is a high flow filter cartridge designed for ultrafiltration pretreatment in industrial water treatment. This liquid filter effectively intercepts suspended solids and protects UF membrane modules from particle fouling. With large dirt holding capacity and low pressure drop, it serves as an ideal alternative to many branded high flow elements, widely adopted in multiple industrial fluid purification projects.
The ALN05-60B high flow filter cartridge is a premium large-capacity pleated filter element specially developed as pretreatment consumable for ultrafiltration equipment. In industrial ultrafiltration systems, raw water often contains suspended particles, colloids, fine silt and organic debris. Without effective pre-filtration, these contaminants will scratch and block ultrafiltration membranes rapidly, raising maintenance costs and shortening membrane service life. The ALN05-60B cartridge solves this pain point perfectly, delivering high throughput while maintaining stable filtration precision.
This filter cartridge adopts an outer-to-inner flow structure, different from conventional small flow filter elements. One single ALN05-60B can replace dozens of standard 2.5-inch filter cartridges, greatly reducing the quantity of filter housings, installation space and replacement labor cost. Customers can match ALN05-60B with our Replace Parker Mega Flow Cartridge when upgrading existing filtration skids, realizing seamless retrofit of old ultrafiltration pretreatment systems.
Constructed with high-quality polypropylene pleated media, the ALN05-60B offers excellent chemical compatibility. It resists most weak acids, weak alkalis and aqueous organic solvents, suitable for continuous operation under normal industrial water temperature. The reinforced core and outer support cage prevent filter media deformation even under high differential pressure. The built-in handle on the top enables fast and safe cartridge replacement without spilling contaminated liquid, which improves site operation efficiency for water treatment stations. Compared with ordinary melt-blown filters, this pleated high flow cartridge has far larger dirt holding capacity, which means longer service cycle and fewer shutdown times for filter change.
The working mechanism of ALN05-60B high flow filter cartridge relies on depth pleated filtration for ultrafiltration pretreatment. When raw water enters the filter housing, fluid flows from the outer surface of the pleated media inward. Suspended solids, sediment, colloidal particles and fine impurities are trapped on the outer and inner layers of the filter medium, while clean permeate flows through the center core and out of the filter housing to the ultrafiltration membrane module.
The pleated design maximizes the effective filtration area within a limited cartridge dimension. More surface area distributes contaminant load evenly, slowing the increase of pressure drop during operation. Unlike surface filtration that only captures particles on the outermost layer, the graded pore structure of ALN05-60B achieves depth filtration: larger particles are intercepted on the outer pleat layer, while smaller fine particles are captured inside the medium. This layered capture method significantly boosts the dirt holding capacity, delaying clogging.
Once the differential pressure between inlet and outlet reaches the preset threshold, operators need to replace the ALN05-60B cartridge. Timely replacement prevents high pressure from breaking the filter medium and letting trapped impurities break through to damage the downstream ultrafiltration membrane. As the first defense barrier of UF systems, this cartridge reduces the particle load entering ultrafiltration modules, cuts membrane cleaning frequency and stabilizes the whole water production capacity of the ultrafiltration equipment.

All parameters of ALN05-60B are tested in our in-house filtration lab. If you need to build a complete pretreatment skid for your ultrafiltration system, you can check our PP high flow water filter cartridge series for combined configuration of multi-grade filtration.
Strict quality management runs through every production step of ALN05-60B high flow filter cartridge. Starting from raw material inspection, all polypropylene raw pellets are tested for tensile strength, chemical resistance and extractables to avoid inferior material affecting filtration performance. The filter media undergoes bubble point test to verify pore size accuracy before pleating.
During production, automatic pleating equipment ensures consistent pleat depth and density for each cartridge. After thermal welding of end caps, every finished ALN05-60B will go through 100% integrity test. The bubble point inspection checks whether there is media crack or leakage, to guarantee no bypass of unfiltered raw water.
We conduct aging and pressure cycle tests in the laboratory to simulate long-term industrial working conditions. Samples are exposed to fluctuating pressure and temperature repeatedly to verify structural stability. Our factory follows ISO 9001 quality management system. Every batch of ALN05-60B comes with test records. We can provide material certificates and filtration performance reports upon request. Our quality standard matches international industrial filter benchmarks, making ALN05-60B a reliable replacement choice for imported high flow filter cartridges used in ultrafiltration pretreatment.
ALN05-60B high flow filter cartridge is mainly used as pretreatment protection for ultrafiltration equipment, and widely applied across many industrial sectors.
Power Plant Water Treatment: Boiler feed water, condensate polishing and circulating water pretreatment. It removes rust, silt and suspended matters, protecting ultrafiltration and reverse osmosis membranes in power stations. Enhancing Power Plant Condensate Water Filtration introduces similar filtration solutions for power industry.
Food & Beverage Industry: Raw water filtration for beverage production, sugar liquid pre-filtration. It retains fine particles without releasing fiber contamination, meeting hygienic water pretreatment requirements before ultrafiltration.
Chemical Industry: Process water, circulating cooling water and chemical liquid purification. Good chemical compatibility allows ALN05-60B to handle slightly corrosive aqueous fluid and protect downstream ultrafiltration units.
Municipal Water Reuse: Reclaimed water treatment and municipal wastewater reuse projects. It intercepts suspended solids and biomass debris from secondary effluent, reducing fouling risk of ultrafiltration membranes.
Pharmaceutical & Cosmetic Water System: Purified water pretreatment, removing particulate impurities to stabilize the operation of ultrafiltration equipment for water for injection production.
Mining & Metallurgy: Mine water treatment and metallurgical process water pre-filtration, reducing solid particle load to extend the service life of ultrafiltration modules.
In all above scenarios, ALN05-60B acts as the primary safety barrier of ultrafiltration systems. It lowers the total cost of ownership by reducing membrane replacement frequency and chemical cleaning cycles.
A: ALN05-60B serves as pretreatment filter for ultrafiltration systems. It intercepts suspended particles, silt and colloids in raw water to prevent physical damage and fouling of ultrafiltration membranes, stabilize water yield and reduce membrane maintenance work.
A: It uses outside-in flow. Raw water flows through the outer pleated media, impurities are trapped on the outer side, and filtered clean liquid flows inward through the central core, which is the standard design for large flow filter cartridges.
A: Monitor the inlet and outlet differential pressure. When pressure difference reaches 2.0~3.4 bar, the cartridge reaches its dirt holding limit and needs immediate replacement to avoid media rupture and contaminant breakthrough.
A: The maximum continuous operating temperature is 80℃. For fluid above this temperature, please contact our engineer to select high temperature resistant filter material solution.
A: Yes. With the same dimension and outside-in flow design, ALN05-60B can replace many mainstream 60 inch high flow filter cartridges for ultrafiltration pretreatment, with customized gasket options for different housing interfaces.
A: EPDM and silicone gaskets are available. EPDM fits most industrial water applications, while silicone gasket suits high-temperature and food-grade fluid working conditions.
