Product Introduction
The HFU620UY020J is a high-performance industrial water treatment filter cartridge, engineered with premium synthetic fiber media and a sturdy structural frame. Designed for small-to-medium-scale pre-filtration and fine filtration applications, this cartridge is optimized to deliver consistent contaminant removal while maintaining low operational resistance. It is tailored to meet the demands of industrial, commercial, and light municipal water treatment systems, providing reliable protection for downstream equipment such as pumps, valves, and precision membrane elements.
Filtration Precision
The HFU620UY020J features a nominal filtration precision of 20 microns. The synthetic fiber media is constructed with a graded pore structure, which enables efficient capture of suspended solids, sand particles, rust, and colloidal contaminants with a particle size of 20 microns and above. This precision ensures that harmful particulates are effectively retained, preventing clogging and wear of subsequent water treatment components.
Flux
Under standard operating conditions (a temperature of 25℃ and an inlet pressure of 0.3 MPa), the HFU620UY020J achieves a rated flux of 20 L/min. The optimized fiber arrangement minimizes flow resistance, allowing for steady water throughput without compromising filtration quality. This flux rate is well-suited for compact water treatment systems, including small boiler feedwater pretreatment, commercial water dispenser purification, and laboratory pure water pre-filtration.
Salt Rejection Rate
As a particulate filtration cartridge, the HFU620UY020J 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 is not a substitute for reverse osmosis (RO) or nanofiltration (NF) membrane elements in desalination or deionization processes.
Pressure Drop
The initial pressure drop of the HFU620UY020J is less than 0.01 MPa when operating at the rated flux. As 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 HFU620UY020J operates based on a particle size-based screening mechanism, rather than molecular weight separation. The MWCO parameter is primarily applicable to membrane filtration products (e.g., ultrafiltration, microfiltration membranes) that separate substances according to their molecular size. Thus, the HFU620UY020J does not have a specific molecular weight cutoff value.
Membrane Thickness
The synthetic fiber filter media layer of the HFU620UY020J has a thickness of 1.2 mm, which balances high filtration efficiency and excellent dirt-holding capacity. The composite structure, including the protective non-woven layer and the rigid support mesh, has an overall thickness of 3.2 mm. This robust 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 HFU620UY020J ranges from 2 to 5 months, depending on the inlet water quality and operating conditions. In water environments with high suspended solid concentrations (exceeding 30 mg/L), the replacement cycle may be shortened to 1–2 months. For well-pretreatment water systems with low contaminant levels, the service life can be appropriately extended, but it should not exceed 5 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.
- Compact and lightweight design: The cartridge’s small footprint makes it suitable for installation in confined spaces such as laboratory cabinets and small industrial equipment rooms.
- Easy maintenance: The standardized size design allows for quick replacement without specialized tools, improving the maintenance efficiency of the system.
- Chemical resistance: The synthetic fiber media is resistant to mild acids and alkalis, making it suitable for a wide range of water treatment environments.
Application Fields
- Small industrial boiler feedwater pretreatment: Used to remove suspended solids from boiler feedwater, preventing scaling and corrosion of boiler tubes and extending equipment service life.
- Commercial drinking water systems: Utilized in water dispensers, small-scale bottled water production lines, and office drinking water purification systems to improve water clarity and taste.
- Laboratory water purification: Applied in the pre-filtration stage of distilled water and ultrapure water preparation systems to protect precision filtration membranes.
- Light industrial process water treatment: Employed in the pre-filtration of rinse water for small electronic component cleaning and cosmetic production, ensuring product quality.
- Residential and commercial HVAC systems: Suitable for central air conditioning circulating water systems to reduce pipeline scaling and equipment wear.
Conclusion
The HFU620UY020J water treatment filter cartridge is a compact, high-efficiency particulate filtration product that excels in cost-effectiveness and reliability. It is specifically designed to address the challenges of solid contaminant removal in small-to-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, compact design, and chemical resistance make it an ideal choice for laboratories, small industrial facilities, and commercial drinking water systems.
