Pentair Aqualine Cartridge Filter for Industrial High‑Volume Pre‑Filtration

Pentair Aqualine Cartridge Filter for Industrial High‑Volume Pre‑Filtration

Pentair Aqualine Cartridge Filter is a well‑known high‑flow pleated cartridge filtration system widely used for RO security pre‑filtration in large‑scale industrial water‑treatment projects. Matched with FRP horizontal filter housings, it works alongside HFU660CAS010JUW large flow filter element, and cooperates with PFTM11UNF high flow filter cartridge to deliver reliable particle removal for seawater desalination, power‑plant boiler feed‑water and industrial water reuse facilities. Pentair Aqualine Cartridge Filter adopts proprietary cross‑linked PolyForm polypropylene pleated media with locked‑pore structure, delivering large effective filtration area, low initial pressure drop and outstanding dirt‑holding capacity. It effectively captures suspended solids, fine sediment and colloidal contaminants, protecting expensive downstream reverse osmosis and ultrafiltration membrane modules from particle abrasion and premature fouling. Featuring single open‑end outside‑in flow path, integrated molded lifting handle and single O‑ring sealing interface, this cartridge filter supports tool‑free fast replacement, shortening maintenance time and lowering long‑term OPEX for global industrial water‑treatment sites.

Product Description

Pentair Aqualine Cartridge Filter is a complete high‑flow filtration solution consisting of pleated filter cartridges and compatible FRP pressure housings, specially engineered for heavy‑duty high‑volume liquid filtration conditions. The mainstream cartridge models include ALN01‑60B, ALN05‑60B, ALN10‑60B and ALN20‑60B, with standard dimension of 60‑inch length and 6.75‑inch outer diameter, single open‑end configuration without complicated springs or guide posts required by conventional filter elements.

The filter cartridge adopts full polypropylene construction, including reinforced inner‑outer support cages, cross‑linked gradient PolyForm pleated polypropylene media, injection‑molded reinforced end caps, rigid PVC central core and high‑performance elastomer O‑ring gaskets. All bonding joints are completed by thermal fusion welding without adhesive, eliminating secondary fluid‑contamination risks caused by glue dissolution. Deep‑pleated design greatly expands effective filtration surface area, achieving remarkable single‑element flux and extending service intervals between replacements. Multiple micron ratings ranging from 1 μm to 90 μm are available, covering coarse pre‑filtration and fine security filtration for diversified raw‑water quality conditions.

The supporting Aqualine‑series FRP filter housing adopts corrosion‑resistant fiber‑reinforced polymer material, complying with ASME pressure standard, which can be installed horizontally or vertically according to site layout requirements. Multiple Aqualine cartridges can be mounted in parallel inside one housing to handle large‑capacity water inflow. When cooperating with upstream multimedia filtration and activated carbon treatment equipment, Pentair Aqualine Cartridge Filter can stably maintain feed‑water SDI value below 5, meeting strict inlet‑water technical specifications of seawater and brackish‑water reverse osmosis systems. It is widely adopted in seawater desalination pretreatment, boiler makeup‑water filtration, petrochemical process‑liquid purification, electronic ultrapure‑water production and industrial wastewater recycling. EPC contractors, plant operators and spare‑part distributors select this product for new water‑treatment skid projects and daily inventory stocking.

Working Principle

Pentair Aqualine Cartridge Filter operates based on outside‑in cross‑flow microfiltration mechanism. Untreated raw water flows into sealed FRP filter housing and evenly distributes to the outer pleated surface of Aqualine cartridges. Under pressure driving force, large‑particle sediment, suspended flocs and coarse impurities are trapped on outer media layers, while tiny colloids and fine particles are intercepted layer‑by‑layer through gradient inner cross‑linked polypropylene media.

Purified filtrate penetrates filter media layers, converges inside rigid PVC central core and flows out toward downstream RO or UF membrane units. The outer‑coarse‑inner‑fine gradient depth‑filtration structure maximizes dirt‑holding capacity and slows differential‑pressure rising speed. As intercepted pollutants keep accumulating during continuous running, inlet‑outlet differential pressure rises gradually. Operators need to replace filter cartridges timely when differential pressure reaches 25‑30 PSID threshold, so as to restore rated water throughput and filtration performance.

All‑polypropylene material delivers good chemical compatibility, tolerating most neutral aqueous solutions and conventional acid‑base cleaning agents for housing routine maintenance. Reinforced inner‑outer support cages resist deformation under high‑speed water‑flow impact and prevent fluid bypass, ensuring stable particle‑removal efficiency throughout service cycle. Standard continuous operating temperature for Aqualine cartridge filter is 54.4 °C (130 °F); customized high‑temperature‑resistant versions can satisfy higher‑temperature working‑condition requirements on request.

FAQ

Q1: What are the most common part numbers of Pentair Aqualine Cartridge Filter?

A1: Mainstream models include ALN01‑60B (1 μm), ALN05‑60B (5 μm), ALN10‑60B (10 μm), ALN20‑60B (20 μm). Users can select proper micron rating according to raw‑water quality and downstream membrane‑system requirements.

Q2: Can Pentair Aqualine Cartridge Filter elements be reused after chemical cleaning?

A2: Aqualine pleated polypropylene cartridges belong to disposable filter elements. Heavy contamination cannot be fully recovered by cleaning. Cleaning will damage media pore structure and reduce filtration accuracy, so replacement is required once differential‑pressure alarm threshold is reached.

Q3: What is the maximum continuous operating temperature for standard Pentair Aqualine Cartridge Filter?

A3: Standard polypropylene Aqualine cartridges support continuous working temperature up to 54.4 °C (130 °F). Custom high‑temperature‑resistant versions are available for special‑condition projects.

Q4: What feed‑water operating conditions are recommended when applying Aqualine Cartridge Filter for RO security filtration?

A4: It is advised to keep feed‑water SDI ≤5; remove free chlorine and strong oxidants to avoid polypropylene media oxidation damage; keep operating temperature within standard‑spec range.

Q5: Can aftermarket replacement cartridges fit original Pentair Aqualine FRP filter housings?

A5: Yes. Dimension, end‑cap structure, O‑ring position and installation interface are fully consistent with original Aqualine standard, supporting direct plug‑and‑play installation without housing mechanical modification.
