PALL HFU640UY700H13W High Flow Filter Cartridge for Ultrafiltration
PALL HFU640UY700H13W is a typical Ultipleat‑series pleated filter cartridge for industrial ultrafiltration pretreatment. This high‑capacity liquid filter traps suspended particles and lowers membrane fouling risk for downstream ultrafiltration modules. Water‑treatment integrators can match this product with PP Pleated Water Filter Cartridge for Ultrafiltration System and other interchangeable filter elements to stabilise feed‑water quality for seawater desalination, power‑plant condensate treatment, electronics high‑purity water and industrial wastewater reuse projects. Buyers should confirm filter housing size and technical parameters before bulk purchasing.
Ultrafiltration equipment serves as a core processing unit in modern industrial water‑treatment projects. It reliably intercepts colloids, microorganisms and macromolecular organic pollutants, providing qualified feed‑water for subsequent reverse osmosis processes. Raw water sourced from surface water, seawater, groundwater and industrial reclaimed wastewater often contains large volumes of silt, pipeline rust and suspended solid particles. Without reliable security pre‑filtration, solid contaminants will accumulate on ultrafiltration membrane surfaces, raise transmembrane pressure, increase chemical cleaning frequency, and greatly shorten the service life of high‑cost ultrafiltration membrane assemblies.
PALL HFU640UY700H13W belongs to Pall Ultipleat high‑flow filter series, specially developed for ultrafiltration front‑end security filtration. Interchangeable replacement cartridges strictly follow original installation dimensional standards, adopting reinforced pleated filter media and heavy‑duty end‑cap construction. Thanks to its unique large‑diameter Ultipleat folding structure, single filter cartridge can support considerable water flow rate. For large‑scale water‑treatment projects, fewer cartridges can satisfy total system flow requirements. This characteristic reduces the required quantity of filter housings, cuts down on‑site installation workload and simplifies spare‑parts inventory management for water‑treatment stations.
When designing multi‑stage pretreatment workflows, many water‑treatment EPC suppliers select PALL HFU640UY700H13W and combine it with PP Large Flow Water Filter for Ultrafiltration Pretreatment to realise graded interception of particles of different sizes. Process engineers can refer to ultrafiltration pretreatment technical resources for configuration suggestions, optimise overall water‑treatment workflow and avoid hidden operational dangers caused by improper pre‑filtration setup.
It should be emphasised that PALL HFU640UY700H13W is a pre‑filtration consumable and cannot replace ultrafiltration equipment itself. It only completes physical interception of granular impurities, while ultrafiltration equipment undertakes separation tasks for colloids, bacteria and macromolecular organics. The two components form mutually complementary links in the whole water‑treatment chain. Many project purchasers focus heavily on ultrafiltration membrane technical parameters yet overlook matching performance of pre‑filtration cartridges. Once inferior alternative filters are selected, risks including particle bypass and filter media fibre shedding may occur. Impurities flowing into ultrafiltration devices will scratch and contaminate membrane sheets, bringing extra expenditure for membrane replacement and system maintenance.
Faced with complex raw‑water working conditions including high‑turbidity surface water, algae‑rich seawater and industrial recycled wastewater, PALL HFU640UY700H13W can work with sedimentation facilities. Large‑size particles complete sedimentation inside sedimentation tanks firstly; most suspended solids get intercepted by high‑flow filter cartridges, and treated water with improved quality flows into ultrafiltration modules. Reasonable multi‑grade pre‑filtration reduces pollutant‑loading borne by ultrafiltration equipment and improves comprehensive economic benefits for long‑term system running.
PALL HFU640UY700H13W adopts thermal‑fusion bonded Ultipleat pleated filter media, cooperating with ultrafiltration equipment to realise staged purification of raw water. Raw water mixed with suspended impurities flows into filter housing and passes through dense pleated filter layers from outside to inside. Silt, rust fragments, granular debris and large suspended solids are trapped on the outer surface of filter cartridges and within pleat gaps. After pre‑filtration processing, water flows out from the central inner core and enters ultrafiltration equipment for further removal of colloidal substances and microbial pollutants.
Optimised Ultipleat pleating craftsmanship expands the effective filtration area of PALL HFU640UY700H13W. Under high‑flow operating circumstances, it maintains relatively low initial pressure drop and delivers outstanding dirt‑holding performance. As intercepted pollutants keep accumulating, pressure difference between filter inlet and outlet rises gradually. On‑site operators need to monitor differential‑pressure readings on a regular basis. When pressure difference reaches the recommended replacement threshold, filter cartridges should be replaced promptly.
If cartridges keep running beyond allowable pressure difference, pollutant bypass risk increases. Unfiltered solid particles flow into ultrafiltration units, possibly resulting in membrane clogging, surface abrasion and continuous flux attenuation. Users need to distinguish functional boundaries clearly: PALL HFU640UY700H13W completes physical particle interception during pretreatment phase, while ultrafiltration undertakes separation of colloidal and organic pollutants. Neither can substitute for the other. Without pre‑filtration protection of qualified filter cartridges, ultrafiltration membranes face higher particle‑erosion risk. Without ultrafiltration processing, pre‑treated water still cannot satisfy feed‑water requirements for reverse osmosis systems. Collaborative operation of pre‑filtration cartridges and ultrafiltration deserves full consideration during industrial water‑treatment process design.

A1: It acts as security pre‑filter for ultrafiltration systems. It intercepts silt, rust fragments and suspended solid particles, reduces particle‑impact risk and protects ultrafiltration membranes from scratching and blocking.
A2: No. This filter cartridge only removes granular impurities. It cannot separate colloids, bacteria and macromolecular organics. Ultrafiltration equipment is still required to get qualified RO feed‑water quality.
A3: It is suitable for raw water with high solid content as first‑stage pre‑filtration. It owns large dirt‑holding capacity, commonly matched with finer‑grade filter elements for two‑stage pretreatment before ultrafiltration membrane modules.
A4: Inferior cartridges may lead to fibre shedding, media damage and particle bypass. Impurities flowing into ultrafiltration units will cause membrane fouling, abrasion and increase system‑maintenance frequency.
A5: It is advised to replace cartridges when inlet‑outlet differential pressure reaches 0.10‑0.14 MPa. Under high‑turbidity raw‑water conditions, replacement cycles will be shortened correspondingly.
A6: Buyers need to confirm housing dimensional compatibility, micron rating, flow‑rate parameters, factory‑test records and supplier technical‑support capacity to satisfy real‑world project requirements.
