Based on the differentiated filtration requirements of each link in pharmaceutical plant purified water units, this customized pharmaceutical grade filter cartridge offers fully customizable nominal filtration precision ranging from 0.22 μm to 50 μm, with gradient precision options tailored to pre-filtration, intermediate filtration and polishing filtration stages. The 0.22 μm ultra-high precision model is customized for the polishing filtration link of purified water units, achieving absolute sterile filtration and intercepting all bacterial cells, fungal spores and submicron particulates to meet the sterile purified water demand for high-end pharmaceutical production; the 1 μm, 5 μm and 10 μm precision models are designed for RO post-filtration, removing fine colloids and particulate impurities in RO effluent to improve the clarity and purity of purified water; the 20 μm, 30 μm and 50 μm medium-coarse precision models are customized for RO pre-filtration and raw water pretreatment of purified water units, efficiently removing large and medium-sized particulates, rust and sediment to protect RO membrane elements from scratch and pollution. All customized precision models maintain consistent and stable interception efficiency under the operating conditions of pharmaceutical purified water units, with zero particle leakage, fully meeting the graded filtration quality requirements of each process link of pharmaceutical plant purified water units.
Flux
The flux performance of this customized pharmaceutical grade filter cartridge is fully optimized and customized according to the design flow rate of pharmaceutical plant purified water units (small, medium and large flow) and the actual operating pressure of each filtration link, with a customizable pure water flux range of 30-180 L/min·m² at 25℃ and 0.1MPa operating pressure. For small-flow purified water units (≤5 m³/h) in laboratory and small pharmaceutical workshops, the cartridge is customized with a low-flux and high-dirt-holding capacity design (30-80 L/min·m²) to adapt to intermittent water supply characteristics; for medium-flow units (5-50 m³/h) in bulk pharmaceutical production workshops, the medium-flux design (80-120 L/min·m²) is adopted to balance filtration efficiency and service life; for large-flow purified water units (>50 m³/h) in large-scale pharmaceutical production bases, the high-flux design (120-180 L/min·m²) is customized with an enlarged effective filtration area to meet the continuous large-volume water supply demand of industrial production. The flux of the customized cartridge remains stable in the recommended operating pressure range of pharmaceutical purified water units, with no sudden attenuation, and the actual flux of pharmaceutical purified water is basically consistent with the pure water flux, fully matching the water supply efficiency of each process link of purified water units.
Salt Rejection Rate
As a dedicated particulate and microbial filtration cartridge customized for pharmaceutical plant purified water units, the product is designed for the interception of insoluble solid impurities, colloids, microorganisms and particulate aggregates in water, and does not have a desalination or ion removal function, with a salt rejection rate close to 0%. It will not intercept soluble inorganic salts, small molecular weight minerals and other ionic components in pharmaceutical purified water, and has no impact on the conductivity, pH value and other key chemical quality indices of purified water specified in pharmacopoeias. The desalination function of pharmaceutical plant purified water units is exclusively undertaken by RO membrane elements, nanofiltration membranes and ion exchange resins in the desalination link; the core role of this customized filter cartridge is to remove particulate and colloidal impurities in each filtration link, reduce the pollution load of desalination and polishing equipment, and ensure their stable desalination efficiency and long service life. The abandonment of desalination design makes the cartridge focus on high-efficiency particulate filtration, with customizable dirt-holding capacity and flux performance to better adapt to the process characteristics of pharmaceutical purified water units.
Pressure Drop
The pressure drop performance of this customized pharmaceutical grade filter cartridge is precisely designed according to the hydraulic resistance requirements of each process link of pharmaceutical plant purified water units, with an initial pressure drop of ≤0.01MPa at 25℃ and rated customized flux for all precision models, which is lower than the industry standard for pharmaceutical filter cartridges. For the RO pre-filtration link with high raw water turbidity, the cartridge is customized with a low-resistance filtration channel structure to further reduce the initial pressure drop (≤0.008MPa), reducing the energy consumption of the raw water delivery pump and avoiding excessive pressure loss in the pretreatment stage; for the polishing filtration link with high precision requirements, the pressure drop is optimized to balance filtration precision and low resistance, ensuring the stable operation of the low-pressure polishing filtration system. With the progress of filtration, the pressure drop of the cartridge increases gradually with the interception of impurities; the recommended terminal operating pressure drop is uniformly customized as ≤0.06MPa for all models, which is adapted to the pressure control range of pharmaceutical plant purified water units. When the pressure drop exceeds this value, the cartridge needs to be replaced in time to avoid excessive system pressure affecting the normal operation of subsequent purified water treatment equipment and the stable water supply of the unit.
Molecular Weight Cutoff (MWCO)
The Molecular Weight Cutoff (MWCO) of this customized pharmaceutical grade filter cartridge is customized in the range of 10,000 Da to 300,000 Da according to the filtration precision and process link of pharmaceutical plant purified water units, with accurate matching between MWCO and filtration precision to realize selective interception of impurities. For the 0.22 μm polishing filtration model, the MWCO is customized to 10,000 Da-30,000 Da, which can efficiently intercept macromolecular microbial cells (bacteria, fungi), macromolecular colloidal proteins and polymer particulate impurities while allowing small molecular weight water molecules and inorganic salts to pass through smoothly; for the 1-10 μm RO post-filtration models, the MWCO is designed as 50,000 Da-150,000 Da, removing medium and large molecular weight colloids and particulate aggregates in RO effluent; for the 20-50 μm RO pre-filtration models, the MWCO is customized to 200,000 Da-300,000 Da, intercepting large molecular weight clay colloids, rust aggregates and insoluble polymer impurities in raw water. The customized MWCO range remains stable under the operating conditions of pharmaceutical purified water units, achieving the dual goal of efficient impurity removal and no impact on the chemical composition of purified water, and meeting the pharmacopoeia requirements for pharmaceutical purified water quality.
Membrane Thickness
The membrane thickness of this customized pharmaceutical grade filter cartridge is customized in the range of 3-10 mm for the effective functional filtration layer according to the filtration precision, flux design and dirt-holding capacity requirements of pharmaceutical plant purified water units, with the total outer diameter thickness of the cartridge customized as 28 mm, 30 mm or 33 mm to perfectly match the installation size of filter housings in different purified water units. For the high-precision polishing filtration models (0.22 μm, 1 μm) with high dirt-holding capacity requirements, the effective filtration layer thickness is customized to 8-10 mm, with a multi-layer dense winding structure to improve the interception effect and service life; for the medium-coarse precision pre-filtration models (20 μm-50 μm) with high flux requirements, the filtration layer thickness is designed as 3-5 mm, with a loose gradient winding structure to reduce flow resistance and improve flux; for the intermediate precision models (5 μm-10 μm) for RO post-filtration, the filtration layer thickness is customized to 6-7 mm to balance filtration precision, flux and dirt-holding capacity. The filtration layer of all customized models adopts a gradient thickness design (outer coarse, inner fine), and the uniform thickness distribution avoids local excessive pressure and filtration layer damage caused by water flow scouring, ensuring the stable operation of the cartridge in the long-term continuous water supply of pharmaceutical purified water units.
Replacement Cycle
The replacement cycle of this customized pharmaceutical grade filter cartridge is customized according to the process link, raw water quality and operating load of pharmaceutical plant purified water units, with a recommended normal replacement cycle ranging from 1 month to 6 months, and a flexible adjustment mechanism adapted to the actual operating conditions of the unit. For the RO pre-filtration link with high raw water turbidity (>10 NTU) and continuous 24-hour operation, the replacement cycle is customized to 1-2 months to avoid excessive impurity accumulation and protect RO membrane elements; for the RO post-filtration link with low turbidity purified water (≤1 NTU), the replacement cycle is designed as 3-4 months; for the polishing filtration link with ultra-pure water and low operating load, the replacement cycle is customized to 4-6 months to reduce the replacement frequency and production cost. In addition, the cartridge must be replaced immediately if any of the following conditions occur in any process link: the terminal pressure drop exceeds the customized 0.06MPa, the filtration flux drops by more than 30% of the initial value and cannot be recovered after physical cleaning, the purified water quality indices (particulate matter, microbial limit) fail to meet pharmacopoeia standards, or the cartridge is used for more than the maximum customized replacement cycle (even if the pressure drop and flux are normal), to ensure the compliant and stable operation of pharmaceutical plant purified water units and the qualification of purified water quality.
