Product Introduction
The HFU640UY020J is a robust, medium-scale industrial water treatment filter cartridge, fabricated with high-grade synthetic fiber filter media and a reinforced structural frame. Engineered for reliable pre-filtration and fine filtration in diverse water treatment systems, this cartridge integrates balanced flow performance, excellent dirt-holding capacity, and chemical resistance to meet the operational demands of industrial, commercial, and municipal water purification applications. It is specifically designed to capture particulate contaminants efficiently, thereby protecting downstream equipment such as reverse osmosis membranes, ion exchange resins, and precision pumps, and ensuring the stability of the entire water treatment process.
Filtration Precision
The HFU640UY020J features a nominal filtration precision of 20 microns. Its synthetic fiber media adopts a graded pore structure, which enables the cartridge to effectively trap suspended solids, sand particles, rust, colloidal substances, and other contaminants with a particle size of 20 microns and above. The uniform pore distribution ensures consistent filtration efficiency throughout the service life of the cartridge, preventing harmful particulates from entering subsequent treatment stages and causing equipment wear or clogging.
Flux
Under standard operating conditions (a temperature of 25℃ and an inlet pressure of 0.3 MPa), the HFU640UY020J delivers a rated flux of 20 L/min. The optimized fiber arrangement minimizes flow resistance, allowing for steady water throughput while maintaining strict filtration standards. This flux rate is tailored for medium-scale water treatment systems, including industrial process water pretreatment, commercial central water purification, and municipal tap water fine filtration, where balanced efficiency and precision are required.
Salt Rejection Rate
As a particulate filtration cartridge, the HFU640UY020J 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 an alternative to reverse osmosis (RO) or nanofiltration (NF) membrane elements in desalination or deionization processes.
Pressure Drop
The initial pressure drop of the HFU640UY020J is less than 0.012 MPa when operating at the rated flux. As contaminants accumulate on the filter surface over time, the pressure drop will gradually increase. To maintain optimal system efficiency and avoid excessive energy consumption, it is recommended to clean or replace the cartridge once the pressure drop reaches 0.09 MPa.
Molecular Weight Cutoff (MWCO)
The HFU640UY020J 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 HFU640UY020J does not have a specific molecular weight cutoff value.
Membrane Thickness
The synthetic fiber filter media layer of the HFU640UY020J has a thickness of 1.4 mm, which strikes an ideal balance between filtration efficiency and dirt-holding capacity. The composite structure, including the protective non-woven fabric layer and the rigid support mesh, has an overall thickness of 3.6 mm. This sturdy design enhances the cartridge’s mechanical strength, preventing deformation or damage during backwashing, high-pressure operation, and long-term continuous use.
Replacement Cycle
The recommended replacement cycle of the HFU640UY020J ranges from 3 to 6 months, depending on the inlet water quality and operating conditions. In water environments with high suspended solid concentrations (exceeding 35 mg/L), the replacement cycle may be shortened to 1–3 months. For well-pretreatment water systems with low contaminant levels, the service life can be appropriately extended, but it should not exceed 6 months to prevent microbial growth, filter clogging, and secondary pollution.
Features
- High dirt-holding capacity: The graded pore synthetic fiber media can trap a large volume of contaminants, extending the service life of the cartridge and reducing maintenance frequency.
- Low initial pressure drop: The optimized fiber structure minimizes energy consumption, lowering the overall operating cost of the water treatment system.
- Chemical resistance: The synthetic fiber media is resistant to mild acids, alkalis, and organic solvents, making it suitable for a wide range of 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-pressure conditions.
- Easy maintenance: The standardized size design allows for quick replacement without specialized tools, improving the maintenance efficiency of the system.
Application Fields
- Industrial process water pretreatment: Used in the pre-filtration stage of chemical, electronic, and metallurgical process water systems to protect core production equipment.
- Commercial central water purification: Applied in shopping malls, hotels, and office buildings for centralized drinking water purification, improving water quality and taste.
- Municipal tap water fine filtration: Employed in small-scale tap water treatment plants to remove residual sediments and improve water clarity.
- Food and beverage industry pre-filtration: Utilized in the filtration of raw water for beverage production and dairy processing, meeting food safety standards.
- HVAC circulating water systems: Suitable for central air conditioning and cooling tower circulating water systems to reduce pipeline scaling and equipment wear.
Conclusion
The HFU640UY020J water treatment filter cartridge is a high-performance particulate filtration product that excels in stability, durability, and cost-effectiveness. It is specifically designed to address the challenges of solid contaminant removal in medium-scale water treatment systems, effectively protecting downstream equipment and improving overall water quality. While it lacks salt rejection and molecular weight cutoff capabilities, its outstanding particulate filtration performance, chemical resistance, and easy maintenance make it an indispensable component in industrial, commercial, and municipal water purification projects.
