Product Introduction
HFU660UY700H13 is a premium high-flow pleated filter cartridge, engineered as a high-performance iteration for demanding industrial water treatment scenarios. It adopts a reinforced composite filter medium, combining polypropylene (PP) microfibers with a hydrophilic modified coating, and is equipped with a high-strength stainless steel inner support frame and a premium EPDM sealing gasket. With an outer diameter of 6 inches (152mm) and available lengths of 20”, 40”, and 60”, this cartridge features a rod-free design to maximize effective filtration area, and is manufactured via a precision ultrasonic welding process to eliminate any risk of adhesive leakage. Compliant with FDA, NSF/ANSI 61, and ISO 9001 standards, it is dedicated to high-efficiency pre-filtration in water treatment systems, effectively capturing suspended solids, colloidal particles, and microbial aggregates to protect downstream critical equipment such as reverse osmosis (RO) membranes, ultrafiltration (UF) modules, and ion exchange columns.
Filtration Precision
The standard filtration precision of HFU660UY700H13 is 70μm, which can intercept 99.9% of particulate matter with a particle size of 70μm and above under rated operating conditions. For customized application needs, it can be tailored to precision levels ranging from 1μm to 100μm, covering both fine filtration requirements for high-purity water and coarse filtration demands for wastewater pretreatment. This precise grading capability ensures stable filtrate quality across diverse water treatment scenarios, preventing particulate abrasion and clogging of downstream precision equipment.
Flux
Flux is a core competitive advantage of HFU660UY700H13. Under standard test conditions (25°C, clean tap water, 1.0 bar operating pressure), the 60-inch length model delivers a flux of 80–100 m³/h; the 40-inch model achieves a flux of 60–70 m³/h; and the 20-inch model provides a flux of 30–35 m³/h. This high-flux performance is attributed to its optimized pleat density (up to 120 pleats per linear foot) and large effective filtration area, which reduces the number of parallel cartridges required in large-flow systems by 35% compared to conventional products, thus saving installation space and system investment costs.
Salt Rejection Rate
As a particulate filtration cartridge, HFU660UY700H13 is not designed for desalination functions, and its salt rejection rate is negligible, generally below 2%. 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 particulate contaminants from adhering to the surface of RO membranes or blocking membrane pores, thereby ensuring the stable high salt rejection rate (typically 95–99%) of downstream desalination equipment.
Pressure Drop
The initial pressure drop of HFU660UY700H13 at rated flow and 20°C is only 0.05–0.08 bar, which is 20% lower than that of traditional filter cartridges of the same specification. As the filtration process proceeds and impurities accumulate on the filter medium surface, the pressure drop will gradually rise. The recommended maximum allowable pressure drop for replacement is 2.6 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 HFU660UY700H13 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 200,000–400,000 Daltons, such as large colloidal organic matter, microbial flocs, and polymer additives in water. However, it has no interception effect on small-molecular substances such as inorganic salts, monosaccharides, and small-molecular organic acids.
Membrane Thickness
The filter membrane thickness of HFU660UY700H13 is precisely controlled at 0.20–0.24 mm, a balanced design that takes into account filtration efficiency, dirt-holding capacity, and water permeability. The moderate thickness ensures the membrane has sufficient mechanical strength to resist water flow impact and backwashing pressure without deformation or rupture. Additionally, the hydrophilic modified coating on the membrane surface reduces the adhesion of hydrophobic impurities, improves dirt-holding capacity, and maintains stable flux during long-term operation.
Replacement Cycle
The replacement cycle of HFU660UY700H13 is determined by raw water turbidity, operating flow rate, and system pressure drop, with significant variability across different application scenarios. In clean industrial process water with turbidity below 3 NTU, the replacement cycle can reach 5–7 months; in high-turbidity water environments such as municipal wastewater pretreatment or surface water treatment with turbidity above 60 NTU, the cycle needs to be shortened to 1–1.5 months. In addition, once the system pressure drop reaches the recommended replacement threshold of 2.6 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.
