It is fully compatible with standard industrial large-diameter water treatment pipeline setups, supports flexible modular parallel and series operation for on-demand scalable system configuration, and features excellent anti-pollution, anti-fouling and broad water quality adaptability to work with complex raw water sources after simple targeted pre-treatment. Easy to install, operate and maintain, the RCP100-40VPP serves as a high-reliability, cost-effective premium core filtration solution for large-scale high-precision water purification projects, realizing industrial ultra-pure process water preparation, municipal tap water deep refinement, pharmaceutical pure water production and wastewater resource reuse with low operational energy consumption and long-term ultra-stable performance.

The RCP100-40VPP features an ultra-high nominal filtration precision of 0.008 microns, with a nanoscale uniformly microporous VPP membrane surface that ensures consistent pore size distribution and eliminates filtration blind spots and micro-impurity leakage even under continuous medium-high flux operation. This extreme precision filtration capability can effectively intercept and remove submicron suspended solids, colloidal particles, bacteria, viruses, algae spores, micro-particle impurities and macromolecular organic pollutants in raw water, ensuring that the effluent water quality stably meets national and industrial Grade I ultra-pure water standards and the strict quality criteria of industrial precision production, municipal high-end drinking water and pharmaceutical GMP production. The filtration precision remains unaltered with slight fluctuations in inlet water turbidity, temperature and impurity content within a reasonable range, providing a solid and reliable technical guarantee for subsequent high-precision water treatment processes or direct use in various high-end water demand scenarios.

Under standard operating conditions (25℃, rated working pressure), the RCP100-40VPP achieves a pure water flux of 40 L/m²·h—a medium-high flux design exclusively tailored for large-scale ultra-high precision water treatment projects that balances efficient water throughput and uncompromised purification quality. The product’s optimized low-resistance wide water flow channel design and high-permeability VPP membrane material effectively minimize flux attenuation caused by membrane fouling; within the normal operating range (water temperature 5℃-40℃, inlet water turbidity ≤8 NTU), the flux remains highly stable with a monthly attenuation rate of ≤2.8% during long-term continuous operation. This medium-high and ultra-stable flux performance fully meets the large-volume high-precision water demand of medium and large-scale industrial production lines, municipal centralized high-standard water supply systems and pharmaceutical production workshops, without sacrificing purification precision for increased water output efficiency, and effectively improves the overall treatment capacity of large-scale high-precision water treatment systems.

The RCP100-40VPP delivers industry-leading salt rejection performance under standard operating parameters, with a 99.0% rejection rate for monovalent inorganic salt ions and a 99.8% rejection rate for divalent inorganic salt ions—performance levels that surpass conventional polypropylene membrane products of the same specification and other VPP membrane models with lower flux. The ultra-dense, high-purity selective separation layer of the premium VPP membrane material forms a high-efficiency ion barrier with strong selectivity, which can effectively block the passage of various salt ions, inorganic impurities and dissolved solids while ensuring the smooth and rapid penetration of water molecules. The salt rejection rate remains extremely stable (variation ≤0.2%) even with slight fluctuations in inlet water salinity (≤3000 mg/L) and operating pressure, making the product an ideal core filtration choice for large-scale ultra-pure water preparation, high-standard brackish water desalination and industrial process water deep softening in industries with strict salt content limits such as semiconductor component manufacturing, pharmaceutical bulk drug production, new energy battery manufacturing and precision instrument processing.

During normal continuous operation at rated medium-high flux and standard water temperature, the pressure drop of the RCP100-40VPP is strictly controlled within the ultra-low range of 0.08-0.12 MPa. The product adopts a highly optimized low-resistance internal structural design, including a smooth wide-diameter water inlet/outlet channel, a high-porosity porous support layer with uniform pore distribution and a streamlined filtration core layout, which minimizes water flow resistance in the medium-high flux filtration process to the greatest extent. This ultra-low pressure drop performance significantly reduces the energy consumption of the water treatment system’s booster pump, lowers the overall operational energy cost of the large-scale water treatment system to the minimum, and fundamentally avoids membrane core damage caused by excessive pressure accumulation in the pipeline. The pressure drop has no obvious increase during the normal service life; a slight rise (≤0.025 MPa) is only observed when regular cleaning is required, which is easy to identify and handle, ensuring the long-term stable, energy-efficient and low-loss operation of the entire large-scale high-precision water treatment system.

The Molecular Weight Cutoff of the RCP100-40VPP is accurately calibrated at 600 Da (Daltons), a precise setting that enables the selective interception of small and medium molecular weight impurities in water while allowing water molecules and beneficial trace small inorganic molecules to pass through smoothly—even under medium-high flux operating conditions. This optimized MWCO performance, tailored for large-scale high-precision water treatment scenarios, can effectively block organic small molecules, colloidal substances, low-medium-molecular-weight polymers, protein impurities, polysaccharides and other micro-pollutants with a molecular weight higher than 600 Da, and is specially suitable for the high-precision separation and purification of water containing low-molecular-weight organic pollutants in large-scale industrial precision production, pharmaceutical synthesis and municipal high-standard water supply. The accurate MWCO design perfectly combines medium-high flux operation with ultra-high purification precision, ensures the strictest effluent water quality standards, and meets the differentiated large-scale high-precision water quality requirements of various industrial, pharmaceutical and municipal application scenarios.

The core filtration membrane of the RCP100-40VPP is a multi-layer composite premium VPP membrane with a total thickness of 170 μm, consisting of a 30 μm ultra-dense selective separation layer (the core functional layer for ultra-high precision filtration and industry-leading salt rejection), a 110 μm high-strength porous support layer (providing super strong mechanical support for the membrane under medium-high flux and pressure-stable working conditions) and a 30 μm anti-fouling protective layer (reducing membrane surface pollution and mechanical wear). The multi-layer thickness and material optimization design are exclusively tailored for medium-high flux, ultra-high precision operation: the ultra-dense selective separation layer is made of high-purity VPP material with advanced nanoscale pore formation and cross-linking technology, ensuring uncompromised ultra-high filtration and salt rejection performance even under high water flow velocity for a long time; the high-strength porous support layer adopts a reinforced cross-linked polypropylene structure with optimized porosity and pore size distribution, enhancing the membrane’s resistance to pressure, water flow impact and mechanical deformation, and avoiding membrane damage during long-term continuous medium-high flux operation; the anti-fouling protective layer is modified with special hydrophilic and anti-adhesion nanotechnology, which effectively reduces the adsorption of organic pollutants, microorganisms and scale-forming substances on the membrane surface and maintains the long-term high permeability and purification efficiency of the membrane core.

Under standard operating conditions and strict adherence to the regular maintenance and deep cleaning schedule, the recommended replacement cycle of the RCP100-40VPP is 36-60 months—an ultra-extended service life specially designed for medium-high flux, large-scale high-precision operating scenarios, far longer than conventional medium-flux polypropylene membrane filtration products and ordinary VPP membrane models. The actual replacement cycle can be flexibly adjusted according to the actual inlet water quality and operating frequency: for raw water with ultra-low impurity content, low salinity and regular professional deep cleaning (1-2 times per quarter), the replacement cycle can be extended to 60 months; for raw water with moderate impurity content and 24-hour continuous medium-high flux operation, the recommended replacement cycle is 36 months to ensure the stable operation of ultra-high filtration precision, flux and salt rejection performance; for raw water with relatively high impurity content, the cycle can be appropriately shortened to 30-36 months based on actual detection data. The main indicators for replacement include a significant decrease in flux (≥15%), a sharp rise in pressure drop (≥0.05 MPa) or a noticeable decline in salt rejection rate (≥0.4%); the product’s modular integrated design makes the replacement process simple and fast, requiring no professional special tools, and a single operator can complete the entire replacement operation within 30 minutes, minimizing the downtime of the large-scale high-precision water treatment system and ensuring the continuous operation of industrial production and municipal high-standard water supply.
