Pentair Aqualine Cartridge for Industrial Ultrafiltration Pretreatment System
Pentair Aqualine Cartridge is a vital pretreatment component for industrial ultrafiltration systems. This liquid filter delivers excellent dirt‑holding capacity and lowers the frequency of regular cartridge replacements. Constructed with high‑performance pleated polypropylene media, it fits mainstream large‑flow filter housings and can cooperate with High‑flow water filter cartridge and Water Filtration PP Pleated Filter to establish complete multi‑stage water‑treatment workflows. It is widely deployed in power, chemical, food‑beverage process water purification projects across global markets.
Pentair Aqualine Cartridge is a large‑diameter high‑flow pleated filter series purpose‑built for ultrafiltration front‑end protection. As a reliable interchange‑grade industrial filter element, it is installed on the upstream side of ultrafiltration membrane modules. Its core function is to trap suspended solids, colloids, fine sediment, pipeline rust and granular contaminants contained in raw water. By removing most particulate impurities in advance, it effectively reduces ultrafiltration membrane fouling risks, decreases chemical cleaning cycles and extends the service life of high‑cost UF membrane components.
Compared with traditional small‑size filter cartridges, Pentair Aqualine Cartridge adopts large‑diameter pleated structural design, which significantly expands the effective filtration area of single filter element. Under equivalent operating flow conditions, fewer cartridges need to be installed inside filter housings. For system integrators and end‑users, this brings tangible advantages: fewer filter housings, reduced installation workload and lower long‑term operation‑maintenance expenditure. When configuring the complete water‑treatment skid, users can match it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to realize multi‑grade gradient pre‑filtration interception effect.
The whole cartridge adopts full polypropylene construction. Thermal‑bond pleating technology replaces adhesive bonding, eliminating secondary pollution risk caused by glue dissolution under long‑time water scouring. End caps and inner‑outer support skeletons are integrally molded, maintaining stable structural performance under continuous high‑flow impact and frequent pressure fluctuation. Whether for newly‑built ultrafiltration water‑making equipment or spare‑part renewal of existing water‑treatment production lines, Pentair Aqualine Cartridge can deliver stable and consistent pretreatment filtering performance.
Pentair Aqualine Cartridge follows surface‑depth composite pleated filtration principle. After raw water flows into filter housing, fluid passes radially inward from the outer surface of filter cartridge. Large solid particles are firstly intercepted on outer pleated surface, while tiny fine impurities penetrate into polypropylene fiber layers and get trapped inside dense fiber gaps.
Benefiting from large‑area pleated layout, pollutants are evenly distributed over the whole filter medium instead of accumulating only on partial surface. This design slows down differential‑pressure rising speed, maximizes dirt‑holding capacity and prolongs the service cycle of filter cartridge. When inlet‑outlet pressure difference reaches preset threshold value, the filter medium is saturated by intercepted pollutants, and operators shall implement cartridge replacement.
It acts as the primary protective barrier for ultrafiltration devices. Without this pretreatment protection, raw water carrying solid particles will directly impact ultrafiltration membrane surfaces. Contaminants will deposit on membrane surfaces, block membrane pores, accelerate fouling rate, increase chemical cleaning frequency and even trigger irreversible membrane damage. When used in series with PFTM11UNF high flow filter cartridge for multi‑stage combined filtration, the overall running stability of water‑treatment systems can be further enhanced. It should be noted that this filter cartridge only intercepts solid particles and cannot remove dissolved ions, so it is only applied for pretreatment before ultrafiltration membranes.

Every batch of Pentair Aqualine Cartridge undergoes complete‑process inspection and finished‑product testing before delivery. Raw material incoming inspection is implemented for polypropylene filter media, support skeletons and end‑caps to ensure batch‑to‑batch consistency. During manufacturing process, sampling inspection covers pleating uniformity, thermal‑bond strength and end‑cap sealing performance.
Finished‑product tests include bubble‑point integrity test, cyclic pressure impulse test and flow pressure‑drop detection. Products with medium cracks, sealing failure or structural looseness will be eliminated completely. Glue‑free thermal‑bond craft avoids the risk of adhesive dissolution contaminating process water.
Products are produced in compliance with industrial filtration quality management specifications. Each filter cartridge is individually packed to avoid dust and particle contamination during storage and transportation. Complete technical datasheets are supplied for engineering design reference. Operators still need to carry out installation inspection before startup to confirm filter housing interface matching and sealing condition.
Pentair Aqualine Cartridge is mainly used as pretreatment filter for ultrafiltration water‑treatment systems, and it is widely applicable to various industrial liquid filtration scenarios.
Industrial ultrafiltration system pretreatment: Trap sediment, rust scale and suspended solids, protect UF membrane elements, reduce chemical cleaning frequency, fit for raw water purification and circulating water treatment projects.
Power industry water treatment: Pre‑filtration for boiler make‑up water and condensed water, remove pipeline rust particles and suspended pollutants.
Food and beverage production: Raw water pretreatment for drinking water and beverage manufacturing, filter granular impurities.
Chemical industry: Process water filtration and circulating cooling water pretreatment for chemical production lines.
Municipal water supply and reclaimed‑water reuse: Large‑flow raw water pre‑filtration for water plants and water recycling projects.
Pharmaceutical and cosmetic water preparation: Sanitary‑grade pre‑filtration for process‑water making equipment.
Users can set multi‑stage gradient filtration according to raw‑water turbidity and pollutant composition of different projects to achieve better overall filtration effect.
A: It serves as ultrafiltration pretreatment protective filter. It intercepts suspended solids, sediment and granular contaminants in raw water, reduces pollutant load on ultrafiltration membranes, slows down membrane fouling, cuts chemical‑cleaning frequency and extends UF membrane service life.
A: There is no fixed time‑based service‑life standard. Service cycle is determined by raw‑water turbidity, pollutant concentration and actual operating flow. It is suggested to replace the cartridge when inlet‑outlet differential pressure reaches 0.35 MPa.
A: It is a disposable pleated filter element. Once filter medium gaps are filled with intercepted pollutants, backwashing cannot restore original filtration performance. Re‑use after cleaning will bring particle leakage risk, direct replacement is recommended.
A: It fits 40‑inch or 60‑inch large‑flow filter housings with special Aqualine locking interface. Before purchasing, please confirm housing interface size, internal space and pressure resistance rating to prevent installation mismatch.
A: Polypropylene material has good tolerance for weak‑acid and weak‑alkali aqueous media. It is not suitable for long‑term running under high‑concentration strong‑acid or strong‑alkali environment. Please consult technical support for special chemical medium working‑condition evaluation.
A: The required quantity is calculated according to system total flow rate, single‑cartridge allowable flow and raw‑water quality. Please refer to technical datasheet for calculation, and reserve proper surplus for fluctuating‑water‑quality working scenarios.
