Product Introduction
The HFU660UY400H13W is a high-performance, corrosion-resistant pleated water filter cartridge engineered for demanding industrial water treatment applications. Built with premium modified polypropylene (PP) membrane materials and a reinforced anti-corrosion housing, this product is specially designed to withstand harsh water quality environments containing acidic or alkaline substances. It excels at removing micro-scale suspended solids, colloidal particles, and insoluble contaminants, serving as a reliable pre-filtration or polishing component to protect downstream equipment like reverse osmosis membranes, ion exchangers, and precision heat exchangers. With its optimized structural design and enhanced chemical stability, it delivers consistent filtration performance even under long-term continuous operation, meeting the strict purification requirements of various industrial sectors.
Filtration Precision
The HFU660UY400H13W features a high filtration precision of 0.5 μm, which enables it to capture ultra-fine particulate impurities that are difficult to remove by conventional filter cartridges. This precise filtration capability ensures that the treated water has extremely low turbidity, effectively preventing micro-particles from adhering to the surface of downstream equipment or mixing into the final product, thus meeting the high-purity water standards required for electronics, pharmaceutical, and fine chemical production.
Flux
Under standard operating conditions (temperature of 25℃ and inlet pressure of 0.2 MPa), the HFU660UY400H13W achieves a nominal flux of 75 m³/h. Its expanded pleat design maximizes the effective filtration area, which not only supports a large water flow rate but also avoids rapid flux attenuation caused by membrane clogging. This high-flux performance makes it suitable for large-scale industrial water treatment systems with high-throughput demands, balancing purification efficiency and system operation costs.
Salt Rejection Rate
As a pleated filter cartridge dedicated to particulate filtration, the HFU660UY400H13W does not have desalination functionality. It cannot remove dissolved salts, ions, or small-molecule organic substances from water, so its salt rejection rate is negligible. For water treatment systems that require both particulate removal and desalination, this filter cartridge can be paired with reverse osmosis (RO) or nanofiltration (NF) modules to achieve comprehensive water purification goals.
Pressure Drop
The initial pressure drop of the HFU660UY400H13W is controlled at ≤0.015 MPa under nominal flux conditions, which minimizes the energy consumption of water pumps and ensures the smooth operation of the entire water treatment system. As contaminants accumulate on the membrane surface during use, the pressure drop will gradually rise. The recommended maximum allowable pressure drop for this product is 0.10 MPa; exceeding this value indicates that the cartridge is heavily clogged and should be replaced promptly to avoid system pressure buildup and filtration efficiency decline.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the HFU660UY400H13W is rated at 8,000 Da. This parameter means the cartridge can effectively retain macromolecular substances and colloids with a molecular weight above 8,000 Da, while allowing water molecules and small-molecule solutes to pass through unimpeded. This characteristic is particularly suitable for industrial processes that need to remove large organic colloids without affecting the content of small-molecule beneficial substances in water, such as pharmaceutical raw material purification and food and beverage production water treatment.
Membrane Thickness
The pleated membrane of the HFU660UY400H13W has a uniform thickness of 0.38 mm. This thickness is carefully calibrated to balance filtration efficiency, mechanical strength, and dirt-holding capacity. The moderately thick membrane not only enhances the product’s resistance to water flow impact and pressure fluctuations but also provides sufficient space for contaminant adsorption, extending the service life of the filter cartridge in harsh operating environments.
Replacement Cycle
The recommended replacement cycle of the HFU660UY400H13W ranges from 2 to 5 months, depending on the turbidity and chemical properties of the raw water. In low-turbidity, neutral water environments (turbidity ≤ 3 NTU), the replacement cycle can be extended to 5 months; in high-turbidity or acidic/alkaline water conditions (pH value 2–12), it is advisable to inspect the cartridge every 2 months and replace it if the pressure drop exceeds the recommended threshold, preventing secondary pollution caused by filter clogging or membrane degradation.
