ALN01‑60B: Large‑Diameter 60‑Inch Water Cartridge Filter For Membrane Pre‑Treatment
Introduction:The ALN01‑60B water cartridge filter is a heavy‑duty 60‑inch large‑diameter pleated filter element built for inside‑to‑outside radial flow operation. Adopting gradient polypropylene pleated media and full hot‑melt thermal bonding without extra adhesive, this water cartridge filter delivers stable particle retention performance for heavy‑load industrial raw water pretreatment. ALN01‑60B effectively traps suspended solids, sediment, rust debris and colloidal pollutants, offering dependable pre‑treatment protection for downstream RO, NF and UF membrane systems, lowering membrane fouling probability and extending overall membrane service life. Its ultra‑large pleated area realizes high single‑cartridge flow output and reduces the quantity of consumables installed inside filter housings. With universal dimensional compatibility for mainstream large‑flow filter vessels on the market, ALN01‑60B is widely adopted in municipal water projects, power plant water production, seawater desalination pre‑filtration and various EPC engineering procurement scenarios.

Working Principle
This High Flow Filter Cartridge ALN01‑60B executes inside‑to‑outside radial filtration workflow. Untreated raw water flows into the inner core cavity from the bottom inlet of the water cartridge filter. Liquid passes radially outward through multi‑layer gradient polypropylene pleated media. Solid contaminants including sediment, rust particles and suspended impurities are trapped on the media surface and within pleated interlayers. Purified water flows outward and transports to downstream pipelines and membrane‑based water‑making equipment.
Benefiting from the 60‑inch ultra‑long pleated construction, ALN01‑60B gains considerable filtration area and sustains low initial pressure drop under high‑flow operating circumstances. As intercepted contaminants keep accumulating, the differential pressure between inlet and outlet will rise gradually. Operators should replace ALN01‑60B once differential pressure hits the recommended threshold value, to recover system flow capacity and prevent excessive pump energy consumption. Gradient‑depth filter media combines surface filtration and depth‑filtration effects, improving overall dirt‑holding capacity for long‑term continuous production operation.
Core Advantages
60‑Inch Ultra‑Long Large‑Diameter StructureALN01‑60B owns 60‑inch element length plus large outer diameter, providing extremely ample effective filtration area per single water cartridge filter. Fewer filter cartridges are required inside filter housing for fixed system flow demand, cutting spare‑part stock pressure and lowering manual replacement workload for large‑scale water‑treatment sites.
Gradient Polypropylene Pleated Media PerformanceMulti‑layer gradient PP pleated media brings steady particle interception capability. ALN01‑60B acts as vital safety pre‑filtration barrier for RO, NF and UF membrane systems, decreasing particulate pollutant load and avoiding mechanical scratch damage to high‑cost membrane sheets.
All‑PP Hot‑Melt Welded AssemblyFilter media, support layers and end caps of ALN01‑60B are 100% polypropylene material assembled by thermal hot‑melt bonding without adhesive. It presents favorable acid‑alkali resistance adapting to most industrial water working conditions, and removes hidden risk of glue dissolution contaminating process fluid.
High Dirt‑Holding Capacity & Low Initial Differential PressureOptimized pleat layout maximizes impurity storage volume. ALN01‑60B can hold large amounts of contaminants before reaching blocking pressure difference, prolonging service cycle and reducing long‑run filter operating cost. Low initial pressure drop cuts pump power loss during 24‑hour non‑stop running.
Universal Interchangeable Size & Simple Field MaintenanceALN01‑60B follows general industry large‑flow dimensional specifications to fit widely‑used filter vessels. Built‑in lifting handle supports fast on‑site cartridge change‑out. Multiple sealing material selections including EPDM, silicone and nitrile rubber are available to match different liquid chemical properties and working temperature ranges.
