ALN05-60B high flow pleated cartridge filter is a 60-inch large-diameter industrial microfiltration element designed for heavy-duty membrane pretreatment and liquid purification projects, generally installed inside horizontal high-flow filter housings alongside PFTM11UNF high flow filter cartridge, and works cooperatively with PFTM1060UHFH13 high flow filter cartridge to build reliable pretreatment systems for reverse osmosis and ultrafiltration units. ALN05-60B adopts proprietary multi-layer gradient polypropylene pleated media, featuring 5μm nominal filtration precision, large effective filtration area, low initial pressure drop and exceptional dirt holding capacity. It efficiently intercepts suspended solids, fine sediment and colloidal contaminants, forming critical security filtration protection to prevent surface abrasion and premature fouling of expensive downstream membrane elements. Equipped with integrated handle and standardized single O-ring sealing structure, ALN05-60B realizes fast plug-and-play replacement, effectively lowering maintenance labor costs for desalination plants, power stations and industrial water recycling facilities worldwide.

Product Description
ALN05-60B belongs to the Aqualine high flow cartridge filter series, the classic 60-inch spiral pleated filter element widely adopted in industrial water treatment. The overall dimension is 60-inch length × 6.75-inch outer diameter, adopting all-polypropylene construction including reinforced inner and outer support cages, cross-linked gradient polypropylene filter media, injection molded reinforced end caps and elastic sealing gaskets. All connection joints adopt thermal fusion welding technology without adhesive, eliminating risks of glue dissolution and secondary contamination to process fluid.
This filter element follows mature outside-in flow configuration. The folded structure greatly expands available filtration area, delivering remarkable single-element flow capacity compared with conventional wound filter cartridges. ALN05-60B maintains stable 5μm nominal filtration efficiency with Beta ratio above 5000, which can reliably trap fine particles escaping multimedia filtration and activated carbon filtration, steadily controlling feed water SDI value below 5 to satisfy strict inlet requirements of seawater desalination RO systems.
Built-in molded handle simplifies on-site extraction and replacement, eliminating complicated auxiliary fixing components. Multiple ALN05-60B cartridges can be installed in parallel inside FRP horizontal filter housings, greatly reducing the total quantity of filter elements and footprint of pretreatment equipment. Widely applied in seawater desalination pretreatment, boiler feed water filtration, petrochemical process liquid purification, industrial reclaimed water reuse and electronic ultrapure water production. Equipment integrators and end users choose ALN05-60B for new skid-mounted systems and periodic spare part replacement.
Working Principle
ALN05-60B high flow cartridge filter operates based on outside-in cross-flow microfiltration mechanism. Untreated raw liquid enters the filter housing and flows to the outer surface of pleated filter media. Suspended particles, sediment and colloidal impurities are captured on the surface and inner layers of gradient polypropylene media. Purified liquid penetrates filter layers, converges inside the central support core and flows out as qualified filtrate.
Large pleated filtration area maintains low flow resistance under high-flow operating conditions. During long-term continuous operation, intercepted pollutants accumulate gradually, leading to slow growth of inlet-outlet differential pressure. Operators should replace ALN05-60B filter cartridge once differential pressure reaches 25–30 PSID threshold to recover system water throughput. Polypropylene raw material provides excellent chemical compatibility, compatible with neutral aqueous liquid and conventional acid-base cleaning solutions for filter housing maintenance. Rigid reinforced support cages prevent medium deformation under water pressure impact, avoid fluid bypass and guarantee stable particle interception efficiency throughout service life.
