Pentair Aqualine Cartridge High‑Flow Pleated Filter Element

Pentair Aqualine Cartridge is a high‑flow single‑open‑end pleated filter element engineered for Pentair Aqualine FRP horizontal pressure housings, widely used as critical security pre‑filtration consumable ahead of industrial RO and UF membrane systems. It is frequently paired with PFTM1060UHFH13 high flow filter cartridge, and cooperates with HFU660CAS010JUW large flow filter element to deliver stable particle interception for seawater desalination, power plant boiler makeup water and industrial water reuse projects. Pentair Aqualine Cartridge adopts cross‑linked gradient polypropylene pleated media, featuring large effective filtration area, low initial pressure drop and outstanding dirt‑holding capacity. It effectively traps suspended solids, fine silt and colloidal contaminants, mitigating particle scratch and colloidal fouling risk for high‑cost downstream membrane modules. Equipped with integrated molded lifting handle and single O‑ring sealing structure, this Aqualine cartridge supports tool‑free quick replacement, reducing equipment downtime and long‑term operation costs for global industrial water treatment sites.

Product Description

Pentair Aqualine Cartridge refers to the core consumable filter element of Aqualine high‑flow filtration series, without including filter housing assembly. Mainstream part numbers cover ALN01‑60B, ALN05‑60B, ALN10‑60B, ALN20‑60B and other specifications. Standard dimension is 60‑inch length and 6.75‑inch outer diameter, adopting single open‑end configuration, specially designed for horizontal installation inside Aqualine‑spec FRP housings.

The whole Aqualine cartridge is constructed from full polypropylene materials, including reinforced inner and outer support cages, cross‑linked gradient pleated polypropylene media, injection‑molded reinforced end caps, rigid PVC central core and high‑elasticity O‑ring gaskets. All connection joints are completed by thermal fusion welding technology without adhesive, completely avoiding secondary fluid contamination caused by glue dissolution. Deep pleated design maximizes effective filtration surface area, realizing high single‑element flux and extending service cycle. Multiple micron ratings from 1 μm to 90 μm are available, covering coarse pre‑filtration and fine security filtration for different raw‑water quality.

As a drop‑in element, Pentair Aqualine Cartridge can be directly installed into matching Aqualine filter housings without any structural modification. Built‑in molded handle simplifies pulling‑out and loading operations during on‑site maintenance. When cooperating with upstream multimedia filtration and activated carbon treatment, the assembled filtration unit can keep feed‑water SDI value below 5 steadily, satisfying strict inlet‑water requirements of seawater and brackish water reverse osmosis systems. This filter cartridge is widely applied in seawater desalination pretreatment, boiler makeup‑water filtration, petrochemical process‑liquid purification, electronic ultrapure‑water production and industrial wastewater recycling. EPC contractors, water plant operators and spare‑part distributors purchase Aqualine cartridges for new project commissioning and routine spare‑part inventory.

Working Principle

Pentair Aqualine Cartridge works on outside‑in cross‑flow microfiltration principle. Untreated raw water enters the sealed FRP filter housing and evenly distributes to the outer pleated surface of Aqualine cartridges. Driven by system pressure, 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 inner gradient polypropylene media.

Purified filtrate penetrates filter media layers, converges inside rigid PVC central core and flows out towards downstream RO or UF membrane units. The outer‑coarse‑inner‑fine gradient depth‑filtration structure improves dirt‑holding capacity and slows the rising speed of inlet‑outlet differential pressure. With continuous system operation, pollutants keep accumulating on filter media. Operators must replace cartridges when differential pressure reaches 25‑30 PSID alarm threshold, so as to restore rated water throughput and filtration performance.

All‑polypropylene material offers good chemical compatibility, tolerating most neutral aqueous solutions and conventional acid‑base cleaning agents for housing maintenance. Reinforced inner‑outer support cages prevent media collapse and deformation under high‑speed water‑flow impact, avoid fluid bypass, and guarantee stable particle‑removal efficiency in the whole service life. Standard continuous operating temperature of Aqualine cartridge is 54.4 °C (130 °F). Custom high‑temperature resistant versions are available for special working‑condition demands.
