HFU660UY400HW Water Treatment Filter Cartridge Product Specification
Product Introduction
The HFU660UY400HW is a premium corrosion-resistant pleated water filter cartridge tailored for harsh industrial water treatment environments. Constructed with high-quality polyvinylidene fluoride (PVDF) membrane and a reinforced anti-corrosion frame, this product is engineered to resist strong acids, alkalis, and organic solvents, making it ideal for complex water quality conditions where conventional PP filter cartridges fail to perform stably. It specializes in removing micro-scale suspended solids, colloidal particles, and insoluble contaminants, serving as a key pre-filtration or polishing component to protect high-value downstream equipment such as reverse osmosis membranes, ion exchange columns, and precision heat exchangers. With its robust structural design and consistent filtration efficiency, it meets the stringent purification demands of heavy industrial sectors.
Filtration Precision
The HFU660UY400HW features a high filtration precision of 1 μm, which enables it to capture fine particulate impurities that would otherwise cause abrasion, scaling, or blockage in downstream systems. This precision level balances high purification quality and high flow rate, ensuring that the treated water meets the purity standards required for medium-to-high precision industrial processes, while avoiding excessive pressure drop caused by over-filtration.
Flux
Under standard operating conditions (temperature of 25℃ and inlet pressure of 0.2 MPa), the HFU660UY400HW achieves a nominal flux of 70 m³/h. Its optimized pleat density and large effective filtration area minimize flow resistance, allowing the cartridge to handle large water volumes without compromising filtration precision. This high-flux performance makes it suitable for large-scale industrial water treatment systems with high-throughput requirements, such as chemical wastewater treatment and petrochemical process water purification.
Salt Rejection Rate
As a pleated filter cartridge focused on particulate filtration, the HFU660UY400HW does not possess desalination capabilities. 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 cartridge can be paired with reverse osmosis (RO) or nanofiltration (NF) membrane modules to achieve comprehensive water purification goals.
Pressure Drop
The initial pressure drop of the HFU660UY400HW is controlled at ≤0.018 MPa under nominal flux conditions, which reduces 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 increase. The recommended maximum allowable pressure drop for this product is 0.12 MPa; exceeding this value indicates that the cartridge is heavily clogged and should be replaced promptly to prevent system pressure buildup and filtration efficiency decline.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the HFU660UY400HW is rated at 10,000 Da. This parameter means the cartridge can effectively retain macromolecular substances and colloids with a molecular weight above 10,000 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, such as fine chemical production and pharmaceutical intermediate purification.
Membrane Thickness
The pleated membrane of the HFU660UY400HW has a uniform thickness of 0.35 mm. This thickness is precisely calibrated to balance three core performance indicators: filtration efficiency, mechanical strength, and chemical resistance. The moderate membrane thickness enhances the product’s ability to withstand water flow impact and pressure fluctuations, while providing sufficient space for contaminant adsorption, thus extending the service life of the filter cartridge in harsh operating environments.
Replacement Cycle
The recommended replacement cycle of the HFU660UY400HW ranges from 3 to 6 months, depending on the turbidity and chemical properties of the raw water. In low-turbidity, neutral to weakly corrosive water environments (turbidity ≤ 5 NTU, pH 4–10), the replacement cycle can be extended to 6 months; in high-turbidity or strongly corrosive water conditions (pH 2–12), it is advisable to inspect the cartridge every 3 months and replace it if the pressure drop exceeds the recommended threshold, preventing membrane degradation and secondary pollution.
