Product Introduction
HFU620CAS010JUW is a compact, high-efficiency pleated filter cartridge specifically engineered for medium-flow industrial water treatment and precision fluid purification applications. It adopts cellulose acetate (CA) as the core filter medium, paired with a lightweight polypropylene (PP) inner support frame and a high-seal EPDM gasket to ensure reliable structural integrity during continuous operation. With a standard outer diameter of 2.5 inches (63.5mm) and optional lengths of 10”, 20”, and 30”, the cartridge features a symmetric pleat design that maximizes effective filtration area while maintaining a compact footprint for space-constrained systems. Manufactured via a low-temperature hot-melt bonding process, it eliminates adhesive residue risks and complies with FDA food contact safety standards and ISO 9001 quality management requirements. This product is dedicated to removing fine suspended solids, colloidal particles, and microbial contaminants from water, providing dependable protection for downstream precision equipment such as ultrafiltration modules, ion exchange resins, and small-scale reverse osmosis (RO) systems.
Filtration Precision
The standard filtration precision of HFU620CAS010JUW is 10μm, which can achieve 99.9% interception efficiency for particles of 10μm and above under rated operating conditions. For customized application needs, it can be tailored to precision levels ranging from 1μm to 25μm, covering ultra-fine filtration demands for pharmaceutical purified water and coarse filtration requirements for industrial process water pretreatment. This precise grading capability ensures consistent filtrate clarity across diverse water treatment systems, preventing fine particulate abrasion and clogging of core downstream components.
Flux
Flux is a key performance indicator of HFU620CAS010JUW. Under standard test conditions (25°C, clean water, 1.0 bar operating pressure), the 20-inch length model delivers a stable flux of 12–16 m³/h; the 10-inch model achieves a flux of 6–8 m³/h; and the 30-inch model provides a flux of 18–22 m³/h. This high-flux performance stems from its hydrophilic CA membrane and optimized pleat density (90 pleats per linear foot), which reduces flow resistance and improves water permeability. Compared with conventional 10μm filter cartridges of the same size, it can increase water throughput by 20% while maintaining filtration efficiency, thus reducing the number of parallel cartridges required in medium-flow systems.
Salt Rejection Rate
As a particulate microfiltration cartridge, HFU620CAS010JUW is not designed for desalination functions, so its salt rejection rate is negligible, generally below 1.5%. Its core function is to remove physical impurities rather than dissolved ionic substances in water. In integrated water treatment systems, it serves as a critical pre-treatment component, preventing fine colloidal particles and microbial contaminants from adhering to the surface of RO or nanofiltration membranes, thereby ensuring the stable high salt rejection rate (98–99.5%) of downstream desalination equipment.
Pressure Drop
The initial pressure drop of HFU620CAS010JUW at rated flow and 20°C is only 0.035–0.055 bar, which is significantly lower than that of traditional cellulose filter cartridges of the same specification. As the filtration process proceeds and impurities accumulate on the membrane surface, the pressure drop will gradually rise. The recommended maximum allowable pressure drop for replacement is 1.9 bar. Maintaining a low pressure drop minimizes the energy consumption of system water pumps, reduces pipeline operating pressure, and extends the service life of the entire water treatment system.
Molecular Weight Cutoff (MWCO)
Since HFU620CAS010JUW relies on particle size-based filtration rather than molecular separation, its molecular weight cutoff (MWCO) is not a core technical parameter and lacks precise calibration. In practical applications, it can roughly intercept macromolecular substances with a molecular weight of 120,000–220,000 Daltons, such as large proteins, colloidal organic matter, and microbial flocs in water. However, it has no interception effect on small-molecular substances including inorganic salts, monosaccharides, and small-molecular organic acids.
Membrane Thickness
The cellulose acetate filter membrane thickness of HFU620CAS010JUW is precisely controlled at 0.09–0.13 mm, a balanced design that takes into account filtration efficiency, dirt-holding capacity, and water permeability. The thin membrane structure reduces flow resistance and ensures high flux, while the reinforced membrane matrix provides sufficient mechanical strength to resist water flow impact and mild backwashing pressure without deformation or rupture. Additionally, the hydrophilic surface of the CA membrane reduces the adhesion of hydrophobic impurities, improving dirt-holding capacity and maintaining stable flux during long-term operation.
Replacement Cycle
The replacement cycle of HFU620CAS010JUW is determined by raw water turbidity, operating flow rate, and system pressure drop, with significant variability across different application scenarios. In ultra-clean industrial process water with turbidity below 1.5 NTU, the replacement cycle can reach 3.5–5.5 months; in medium-turbidity water environments such as small-scale pharmaceutical purified water pretreatment or electronics factory process water treatment with turbidity above 12 NTU, the cycle needs to be shortened to 0.6–1.1 months. In addition, once the system pressure drop reaches the recommended replacement threshold of 1.9 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.
