ALN01‑60B: 60‑Inch Extra‑Long High Flow Pleated Cartridge Filter
Introduction:The ALN01‑60B Aqualine cartridge filter is a 60‑inch large‑diameter high‑flow pleated filter element designed for inside‑to‑outside radial flow operation. Manufactured with gradient polypropylene pleated media and full hot‑melt thermal bonding without adhesive, this cartridge filter delivers stable particle removal performance for heavy‑duty industrial water pretreatment. ALN01‑60B effectively captures suspended solids, sediment, rust particles and colloidal contaminants, providing reliable pre‑treatment protection for downstream RO, NF and UF membrane systems, lowering membrane fouling risk and extending membrane service life. Its extra‑large pleated area supports high single‑element flow rate, reducing total cartridge quantity required inside filter housings. Dimensionally compatible with mainstream industry‑standard large‑flow filter vessels, ALN01‑60B is widely adopted for municipal water projects, power plant water‑making, seawater desalination pre‑filtration and EPC engineering procurement scenarios.

Working Principle
ALN01‑60B cartridge filter applies inside‑to‑outside radial filtration mechanism. Untreated raw water flows into the inner core cavity from the bottom inlet of the filter cartridge. Liquid passes radially outward through multi‑layer gradient polypropylene pleated media. Solid impurities including sediment, rust debris and suspended particles are trapped on the media surface and inside pleated interlayers. Purified water flows outward into downstream pipelines and membrane equipment.
Thanks to the 60‑inch extra‑long pleated structure, ALN01‑60B achieves remarkable filtration area and maintains low initial pressure drop under high‑flow operating conditions. When intercepted contaminants keep accumulating, the differential pressure between inlet and outlet will rise gradually. Operators should replace ALN01‑60B once differential pressure reaches recommended threshold value, to restore system flow capacity and avoid excessive pump energy consumption. Gradient‑depth filter media combines surface filtration and depth‑filtration effects to improve overall dirt‑holding capacity for long‑term continuous running.
Core Advantages
60‑Inch Extra‑Long Large‑Diameter High‑Flow StructureALN01‑60B features 60‑inch element length and large outer diameter, offering extremely large effective filtration area per single cartridge. For given system flow demand, fewer filter cartridges are required inside filter housing, which cuts spare‑part inventory and reduces manual replacement workload for large‑scale water treatment sites.
Gradient Polypropylene Pleated Media PerformanceMulti‑layer gradient PP pleated media delivers stable particle retention capability. ALN01‑60B acts as critical safety pre‑filtration barrier for RO, NF and UF membrane systems, reducing particulate pollutant load and preventing mechanical scratch damage to high‑cost membrane sheets.
Full‑PP Hot‑Melt Welded ConstructionFilter media, support layers and end caps of ALN01‑60B are all polypropylene material assembled by thermal hot‑melt bonding, no adhesive. It possesses good acid‑alkali tolerance for most industrial water conditions and eliminates the hidden risk of glue leaching contaminating process fluid.
Superior Dirt‑Holding Capacity with Low Initial Differential PressureOptimized pleat layout maximizes contaminant storage volume. ALN01‑60B can hold large volume of impurities before reaching blocking pressure difference, extending service cycle and decreasing overall filter operating cost. Low initial pressure drop minimizes pump energy loss during continuous 24‑hour operation.
Standard Interchangeable Dimension & Convenient MaintenanceALN01‑60B is dimensionally designed to fit widely‑used industry large‑flow filter vessels. Built‑in lifting handle supports fast on‑site cartridge change‑out. Multiple sealing material options including EPDM, silicone and nitrile rubber are available to match different liquid chemical properties and working temperature ranges.
