HP1351A10ANP01 Water Treatment Product Detailed Description

Product Introduction

HP1351A10ANP01 is a high-precision pleated filter cartridge engineered for medium-flow industrial water treatment and critical fluid purification applications. It adopts a polyethersulfone (PES) microfiltration membrane as the core filter medium, paired with a corrosion-resistant polypropylene (PP) inner support frame and a high-seal Buna-N gasket. With a standard outer diameter of 2.75 inches (70mm) and a nominal length of 10 inches (254mm), this cartridge features a symmetric pleat design to maximize effective filtration area while ensuring uniform flow distribution. Manufactured via a class 100 cleanroom process, it eliminates particulate contamination during production and complies with FDA food contact safety standards and ISO 13485 quality management requirements. This product is dedicated to removing fine suspended solids, colloidal particles, and microbial contaminants from water, providing reliable protection for downstream precision equipment such as ultrafiltration modules, ion exchange resins, and precision dispensing systems.

Filtration Precision

The standard filtration precision of HP1351A10ANP01 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 0.1μm to 20μm, 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 quality across diverse water treatment systems, preventing fine particulate abrasion and clogging of core downstream equipment.

Flux

Flux is a core performance indicator of HP1351A10ANP01. Under standard test conditions (25°C, clean water, 1.0 bar operating pressure), the cartridge delivers a stable flux of 8–12 m³/h. This high-flux performance is attributed to its hydrophilic PES membrane and optimized pleat density (80 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 25% while maintaining filtration efficiency, thus reducing the number of parallel cartridges required in medium-flow systems.

Salt Rejection Rate

As a particulate microfiltration cartridge, HP1351A10ANP01 is not designed for desalination functions, so its salt rejection rate is negligible, generally below 1%. 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 nanofiltration or reverse osmosis membranes, thereby ensuring the stable high salt rejection rate (98–99.5%) of downstream desalination equipment.

Pressure Drop

The initial pressure drop of HP1351A10ANP01 at rated flow and 20°C is only 0.03–0.05 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 1.8 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 HP1351A10ANP01 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 100,000–200,000 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 PES filter membrane thickness of HP1351A10ANP01 is precisely controlled at 0.08–0.12 mm, a ultra-thin design that balances 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 backwashing pressure without deformation or rupture. Additionally, the hydrophilic surface of the PES 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 HP1351A10ANP01 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 NTU, the replacement cycle can reach 3–5 months; in medium-turbidity water environments such as pharmaceutical purified water pretreatment or electronics factory process water treatment with turbidity above 10 NTU, the cycle needs to be shortened to 0.5–1 month. In addition, once the system pressure drop reaches the recommended replacement threshold of 1.8 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.
