Pentair High Flow Cartridge Filter for Industrial Membrane Guard Filtration

Pentair High Flow Cartridge Filter belongs to the well‑known Aqualine product portfolio, a large‑diameter pleated filter element widely adopted for industrial liquid microfiltration and reverse osmosis security filtration. It is commonly fitted inside horizontal FRP filter housings together with POV12UNPFA high flow filter cartridge, and cooperates with HFU660CAS010JUW large flow filter element to build complete pretreatment pipelines for seawater desalination and industrial water reuse projects. Pentair High Flow Cartridge Filter adopts cross‑linked gradient polypropylene pleated media, delivering huge effective filtration area, low initial pressure drop and outstanding dirt‑holding capacity. It reliably traps suspended solids, fine sediment and colloidal contaminants, delivering critical protection to avoid abrasion and premature fouling of expensive downstream RO and UF membrane components. Equipped with integrated molded handle and single O‑ring sealing interface, this cartridge enables fast plug‑and‑play replacement, effectively cutting maintenance labor expenditure for power plants, petrochemical facilities and coastal desalination installations across the globe.

Product Description

Pentair High Flow Cartridge Filter is the flagship disposable pleated filtration component of Pentair Aqualine series, represented by mainstream models ALN01‑60B, ALN05‑60B, ALN10‑60B and ALN20‑60B. Standard dimension is 60‑inch length with 6.75‑inch outer diameter, specially developed for heavy‑duty high‑flow industrial water treatment conditions. The whole cartridge adopts full polypropylene construction, including reinforced inner‑outer support cages, cross‑linked gradient pleated polypropylene media, injection‑molded reinforced end caps and elastic sealing gaskets. All joints are completed by thermal fusion welding without adhesive, eliminating hidden risks of glue dissolution and secondary contamination to process fluid.

This filter cartridge applies mature outside‑in flow configuration. Multiple nominal precision grades ranging from 1 μm to 90 μm are available to satisfy diversified security filtration demands in front of membrane separation equipment. Dense deep‑pleated layout greatly expands effective filtration area, achieving remarkable single‑element flow capacity when compared with conventional small‑diameter wound filter cartridges. It can efficiently capture fine particles escaping multimedia filtration and activated carbon units, stably controlling feed‑water SDI value below 5 and satisfying strict inlet requirements of seawater reverse osmosis systemsCodeline.

Built‑in integral molded handle simplifies on‑site extraction and replacement without extra auxiliary fixtures. Multiple Pentair high‑flow cartridges can be installed in parallel inside Aqualine‑style horizontal filter housings, greatly reducing total cartridge quantity and minimizing pretreatment equipment footprint. Pentair High Flow Cartridge Filter is widely deployed in seawater desalination pretreatment, boiler feed‑water filtration, petrochemical process‑liquid purification, industrial reclaimed‑water reuse and electronic ultrapure‑water production. System integrators and end‑users select this cartridge for new skid‑mounted water‑treatment systems as well as daily spare‑part renewal.

Working Principle

Pentair High Flow Cartridge Filter operates based on outside‑in cross‑flow microfiltration mechanism. Untreated raw liquid enters the closed filter housing and flows toward the outer surface of pleated filter media. Suspended particles, sediment and colloidal impurities are captured on the outer surface and inner gradient layers of polypropylene media. Purified liquid penetrates filter layers, converges inside the central support core and flows out as qualified filtrate toward downstream membrane equipment.

Gradient layered media realizes outer‑coarse‑inner‑fine depth filtration, significantly improving dirt‑holding capacity and slowing differential‑pressure rising speed. During long‑term continuous running, intercepted pollutants accumulate gradually, leading to slow growth of inlet‑outlet differential pressure. Operators need to replace the cartridge once differential pressure reaches 25‑30 PSID threshold to restore system water throughput.

Polypropylene raw material provides excellent chemical compatibility, compatible with neutral aqueous liquid and regular acid‑base cleaning solutions for filter‑housing maintenance. Rigid reinforced support cages prevent medium deformation under high‑speed water‑flow impact, avoid fluid bypass and guarantee stable particle‑interception efficiency throughout the whole service life.

• FAQ

Q1: What typical models belong to Pentair High Flow Cartridge Filter Aqualine series?

A1: Mainstream specifications include ALN01‑60B, ALN05‑60B, ALN10‑60B and ALN20‑60B. Different micron ratings can be selected according to raw‑water quality and membrane‑system requirements.

Q2: Can Pentair High Flow Cartridge Filter be cleaned and reused after fouling?

A2: Pentair Aqualine pleated polypropylene cartridge is a disposable filter element. Conventional chemical cleaning cannot fully restore flux after severe contamination. It is recommended to replace once differential pressure exceeds 25‑30 PSID alarm limit.

Q3: What maximum continuous operating temperature can Pentair High Flow Cartridge Filter withstand?

A3: Standard polypropylene version supports continuous working temperature up to 54.4 °C (130 °F). Contact our engineers if customized high‑temperature‑resistant versions are required.

Q4: What feed‑water index is recommended when applying this cartridge for RO security filtration?

A4: It is advised to control feed‑water SDI ≤ 5, remove free chlorine to avoid oxidation damage to filter media, and keep raw‑water temperature within standard operating range.

Q5: Is Pentair High Flow Cartridge Filter fully interchangeable with original Aqualine filter housings?

A5: Yes. Dimensions, end‑cap sealing structure and installation interface are fully consistent with original Pentair Aqualine series, supporting direct plug‑and‑play installation without housing modification.
