Product Introduction
The HFU640UY045J is a heavy-duty medium-to-large scale industrial water treatment filter cartridge, manufactured with premium synthetic fiber media and a reinforced structural frame. Engineered for high-efficiency coarse filtration and pre-filtration applications, this cartridge integrates excellent dirt-holding capacity, stable flow performance, and strong pressure-bearing capacity. It is tailored to meet the rigorous demands of industrial, commercial, and municipal water treatment systems, effectively capturing large particulate contaminants to protect downstream precision equipment such as fine filters, reverse osmosis membranes, and heat exchangers, ensuring the long-term stability of the entire water treatment process.
Filtration Precision
The HFU640UY045J features a nominal filtration precision of 45 microns. Its synthetic fiber media adopts a graded pore structure, which enables the cartridge to efficiently trap suspended solids, sand particles, large rust fragments, and coarse colloidal contaminants with a particle size of 45 microns and above. This precision level is optimized for coarse filtration scenarios, where the core goal is to remove large impurities, reduce the load of subsequent fine filtration components, and extend their service life.
Flux
Under standard operating conditions (a temperature of 25℃ and an inlet pressure of 0.3 MPa), the HFU640UY045J delivers a rated flux of 45 L/min. The optimized fiber arrangement and large surface area design minimize flow resistance, allowing for high-volume water throughput without excessive pressure buildup. This flux rate is well-suited for medium-to-large scale water treatment systems, including industrial process water pre-filtration, commercial central water supply systems, and municipal tap water coarse purification projects.
Salt Rejection Rate
As a particulate filtration cartridge, the HFU640UY045J is not designed for salt removal. Its core function focuses on the physical separation of solid contaminants from water, rather than the rejection of dissolved salts or ions. Therefore, the product has a negligible salt rejection rate and should not be used as a substitute for reverse osmosis (RO) or nanofiltration (NF) membrane elements in desalination or deionization processes.
Pressure Drop
The initial pressure drop of the HFU640UY045J is less than 0.01 MPa when operating at the rated flux. As coarse contaminants accumulate on the filter surface over time, the pressure drop will gradually increase. To ensure optimal system efficiency and avoid unnecessary energy consumption, it is recommended to clean or replace the cartridge once the pressure drop reaches 0.08 MPa.
Molecular Weight Cutoff (MWCO)
The HFU640UY045J operates based on a particle size-based screening mechanism, rather than molecular weight separation. The MWCO parameter is primarily applicable to membrane filtration products such as ultrafiltration and microfiltration membranes, which separate substances according to their molecular size and structure. Thus, the HFU640UY045J does not have a specific molecular weight cutoff value.
Membrane Thickness
The synthetic fiber filter media layer of the HFU640UY045J has a thickness of 1.4 mm, which balances efficient coarse filtration and enhanced dirt-holding capacity. The composite structure, including the protective non-woven pre-filter layer and the rigid support mesh, has an overall thickness of 3.6 mm. This robust design enhances the cartridge’s mechanical strength, preventing deformation or damage during backwashing, high-pressure flushing, and long-term continuous operation.
Replacement Cycle
The recommended replacement cycle of the HFU640UY045J ranges from 3 to 7 months, depending on the inlet water quality and operating conditions. In water environments with high concentrations of coarse suspended solids (exceeding 70 mg/L), the replacement cycle may be shortened to 1–3 months. For well-pretreatment water systems with low coarse contaminant levels, the service life can be appropriately extended, but it should not exceed 7 months to prevent microbial growth, filter clogging, and secondary pollution.
Features
- Superior dirt-holding capacity: The graded pore synthetic fiber media can trap a large volume of coarse contaminants, significantly reducing the maintenance frequency of the cartridge and downstream equipment.
- Low initial pressure drop: The optimized large-pore structure minimizes flow resistance, lowering energy consumption and reducing the overall operating cost of the water treatment system.
- Excellent chemical resistance: The synthetic fiber media is resistant to mild acids, alkalis, and organic solvents, making it suitable for a wide range of harsh industrial water treatment environments.
- Durable construction: Reinforced end caps and an anti-deformation support frame enhance the cartridge’s pressure-bearing capacity, ensuring stable operation under high-flow and high-pressure conditions.
- Easy maintenance and replacement: The standardized size design allows for quick installation and replacement without specialized tools, improving the maintenance efficiency of the system.
Application Fields
- Industrial process water pre-filtration: Used in chemical, electronic, and metallurgical process water systems to remove coarse impurities, protecting core production equipment and ensuring process stability.
- Commercial central water supply systems: Applied in large shopping malls, hotels, and hospitals to pre-filter tap water, removing sand and rust and improving the quality of terminal water supply.
- Municipal tap water coarse purification: Employed in medium-scale water treatment plants to reduce the load of fine filtration systems and extend the service life of precision filter elements.
- Industrial cooling water circulation systems: Utilized in power plant and manufacturing cooling water systems to prevent pipeline clogging and heat exchanger scaling.
- Wastewater treatment pre-filtration: Suitable for the pre-filtration stage of industrial wastewater treatment systems, removing large suspended solids to facilitate subsequent purification processes.
Conclusion
The HFU640UY045J water treatment filter cartridge is a high-performance, cost-effective coarse filtration product that excels in handling large particulate contaminants in medium-to-large scale water treatment systems. It effectively protects downstream fine filtration equipment and core production components, reducing the overall maintenance cost of the water treatment system. While it lacks salt rejection and molecular weight cutoff capabilities, its outstanding coarse filtration performance, low energy consumption, and durable construction make it an indispensable component in industrial process water treatment, commercial central water supply, and municipal tap water purification projects.
