ALN01-60B high flow pleated water cartridge filter is a 60-inch large-diameter industrial microfiltration element dedicated to membrane pretreatment and industrial liquid purification projects, generally installed inside horizontal filter housings alongside PFTM11UNF high flow filter cartridge, and works cooperatively with PFTM1060UHFH13 high flow filter cartridge to construct complete security filtration systems for reverse osmosis and ultrafiltration devices. ALN01-60B adopts multi-layer gradient polypropylene pleated media, featuring large effective filtration area, low initial pressure loss and outstanding dirt holding capacity. It effectively intercepts suspended solids, fine sediments and colloidal pollutants, forming a vital protective barrier to prevent particle abrasion and premature fouling of expensive downstream membrane elements. With standardized end cap structure and stable dimensional consistency, ALN01-60B supports convenient plug-and-play installation and routine maintenance, serving as a trusted filtration solution for petrochemical plants, power stations, seawater desalination and industrial water recycling facilities.

Product Description
ALN01-60B high flow pleated cartridge filter is a widely used industrial high-flow filtration component for heavy-duty water treatment applications. The whole filter element adopts all-polypropylene structure, consisting of reinforced inner and outer support cages, gradient pleated polypropylene filter media, injection molded reinforced end caps and elastic sealing gaskets. All assembly joints adopt thermal fusion welding technology without adhesive, eliminating hidden risks of glue dissolution and secondary contamination to process fluid.
The filter follows the mature outside-in filtration flow path. The intensive pleated layout greatly expands effective filtration area, delivering higher single-element flow capacity and longer service intervals compared with conventional string-wound filter cartridges. ALN01-60B can efficiently capture tiny particles that escape multimedia filtration and activated carbon filtration units, stably controlling inlet water SDI value to satisfy strict inlet requirements of reverse osmosis and ultrafiltration membrane systems.
ALN01-60B filter cartridge is extensively applied in boiler feed water preparation, industrial circulating water purification, petrochemical process liquid filtration, high-salinity wastewater treatment and electronic ultrapure water production. System integrators and end customers adopt ALN01-60B for new skid-mounted water treatment systems and daily spare part replacement. Multiple ALN01-60B cartridges can be installed in parallel inside large horizontal filter housings to meet continuous high-flow filtration demands of large-scale industrial facilities.
Working Principle
ALN01-60B high flow cartridge filter operates based on outside-in cross-flow microfiltration mechanism. Untreated liquid enters the filter housing and flows toward the outer surface of pleated filter media. Particulate pollutants, sediment and colloids are captured on the surface and inner layers of gradient polypropylene media. Purified liquid penetrates filter layers, converges inside the inner 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 rise of inlet-outlet differential pressure. Operators need to replace ALN01-60B filter cartridge once differential pressure reaches the preset alarm 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 impurity interception efficiency throughout service life.
