HFU660CAS010JUW Water Treatment Product Detailed Description

Product Introduction

HFU660CAS010JUW is a premium mega-flow pleated filter cartridge, engineered for large-scale industrial water treatment plants, municipal water supply systems, and high-throughput fluid purification scenarios. It adopts cellulose acetate (CA) as the core filter medium, paired with a reinforced 304 stainless steel internal support frame and a high-seal fluorosilicone gasket to ensure structural integrity under extreme pressure and flow conditions. With a standard outer diameter of 6 inches (152mm) and optional lengths of 20”, 40”, 60”, and 80”, the cartridge features a high-density pleat design that maximizes effective filtration area while minimizing flow resistance. Manufactured via cleanroom-grade hot-melt welding, it eliminates adhesive residue risks and complies with strict international standards including FDA, NSF/ANSI 61, and GMP. This product is dedicated to removing fine suspended solids, colloidal particles, and microbial aggregates from large-volume water systems, providing reliable protection for downstream critical equipment such as reverse osmosis (RO) membrane arrays, ultrafiltration (UF) modules, and industrial heat exchangers.

Filtration Precision

The standard filtration precision of HFU660CAS010JUW is 10μm, which can achieve 99.98% 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 0.5μm to 30μm, covering ultra-fine filtration demands for high-purity industrial water and coarse filtration requirements for municipal wastewater pretreatment. This precise grading capability ensures consistent filtrate quality across diverse large-flow water treatment systems, preventing fine particulate abrasion and clogging of core downstream components.

Flux

Flux is a core competitive advantage of HFU660CAS010JUW. Under standard test conditions (25°C, clean water, 1.5 bar operating pressure), the 80-inch length model delivers an ultra-high flux of 85–100 m³/h; the 60-inch model achieves a flux of 65–75 m³/h; the 40-inch model provides a flux of 45–55 m³/h; and the 20-inch model delivers a flux of 22–28 m³/h. This superior flux performance stems from its hydrophilic CA membrane and optimized pleat density (130 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 40% while maintaining filtration efficiency, thus significantly reducing the number of parallel cartridges required in large-scale water treatment systems and saving installation space.

Salt Rejection Rate

As a particulate microfiltration cartridge, HFU660CAS010JUW is not designed for desalination functions, so 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 fine colloidal particles and microbial contaminants from adhering to the surface of RO membranes or blocking membrane pores, thereby ensuring the stable high salt rejection rate (97–99.5%) of downstream desalination equipment.

Pressure Drop

The initial pressure drop of HFU660CAS010JUW at rated flow and 20°C is only 0.05–0.08 bar, which is 30% 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 2.5 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 HFU660CAS010JUW 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 160,000–260,000 Daltons, such as large colloidal organic matter, microbial flocs, and polymer additives in water. However, it has no interception effect on small-molecular substances including inorganic salts, monosaccharides, and small-molecular organic acids.

Membrane Thickness

The cellulose acetate filter membrane thickness of HFU660CAS010JUW is precisely controlled at 0.12–0.16 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 high water flow impact and backwashing pressure without deformation or rupture. Additionally, the hydrophilic coating on the membrane surface reduces the adhesion of hydrophobic impurities, improves dirt-holding capacity, and maintains stable flux during long-term continuous operation.

Replacement Cycle

The replacement cycle of HFU660CAS010JUW is determined by raw water turbidity, operating flow rate, and system pressure drop, with significant variability across different application scenarios. In ultra-clean large-flow industrial process water with turbidity below 2.5 NTU, the replacement cycle can reach 5–7 months; in medium-turbidity water environments such as power plant cooling water pretreatment or municipal tap water treatment with turbidity above 20 NTU, the cycle needs to be shortened to 0.8–1.4 months. In addition, once the system pressure drop reaches the recommended replacement threshold of 2.5 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.
