Product Introduction
The HFU660UY400H4W is a high-performance pleated water filter cartridge designed for heavy-duty industrial water treatment applications. Crafted with premium polypropylene (PP) membrane materials and an optimized structural design, this product is engineered to deliver exceptional particulate removal efficiency, high dirt-holding capacity, and long-term operational stability. It serves as a critical pre-filtration or polishing component in various water treatment systems, effectively eliminating suspended solids, colloidal particles, and other insoluble contaminants to safeguard downstream equipment and ensure the quality of treated water meets strict industrial standards.
Filtration Precision
The HFU660UY400H4W features a precise filtration rating of 0.5 μm, which enables it to capture even the micro-scale particulate impurities that are difficult to remove by conventional filter cartridges. This high-precision performance ensures that the filtered water has extremely low turbidity, making it suitable for applications that demand high-purity water quality, such as electronics manufacturing and pharmaceutical production.
Flux
Under standard operating conditions (temperature of 25℃ and inlet pressure of 0.2 MPa), the HFU660UY400H4W achieves a nominal flux of 70 m³/h. Its expanded pleated membrane design maximizes the effective filtration area, which not only supports a large water flow rate but also avoids flux attenuation caused by membrane clogging in a short period, thus meeting the high-throughput requirements of large-scale industrial water treatment systems.
Salt Rejection Rate
As a pleated filter cartridge focused on particulate filtration, the HFU660UY400H4W does not have the function of removing dissolved salts and ions from water. Therefore, its salt rejection rate is almost negligible. For water treatment systems that require desalination, this filter cartridge can be used in conjunction with reverse osmosis (RO) or nanofiltration (NF) membrane modules to achieve comprehensive purification effects.
Pressure Drop
The initial pressure drop of the HFU660UY400H4W is controlled at ≤0.018 MPa under nominal flux conditions, which helps reduce the energy consumption of the water pump 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 0.12 MPa, beyond which the filter cartridge should be replaced in a timely manner to prevent system efficiency degradation.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the HFU660UY400H4W is rated at 8,000 Da. This parameter means that the filter 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 freely. This characteristic is crucial for maintaining the stability of the water composition in specific industrial processes that require the retention of certain macromolecular components.
Membrane Thickness
The pleated membrane of the HFU660UY400H4W has a uniform thickness of 0.35 mm. This thickness is carefully calibrated to balance three core performance indicators: filtration efficiency, mechanical strength, and dirt-holding capacity. The moderate membrane thickness ensures that the product can withstand the impact of water flow and pressure fluctuations during long-term operation, and also provides sufficient space for contaminant adsorption, thus extending the service life of the filter cartridge.
Replacement Cycle
The recommended replacement cycle of the HFU660UY400H4W is 2–5 months, which is closely related to the turbidity of the raw water and the operating load of the system. In low-turbidity water environments (turbidity ≤ 3 NTU), the replacement cycle can be extended to 5 months; in high-turbidity working conditions (turbidity ≥ 20 NTU), it is recommended to inspect the filter cartridge every 2 months and replace it if necessary to avoid system blockage and secondary pollution.
