RCP045-60NPP NPP Water Treatment Filtration Unit – Professional for High-Flow Water Processing & Purification Projects

The RCP045-60NPP is a high-flux, industrial-grade water treatment filtration product engineered with advanced NPP (Novel Polypropylene) membrane technology, exclusively optimized for high-throughput water purification and resource reuse in industrial, commercial and municipal scenarios. This model integrates a high-performance NPP filtration core with a reinforced pressure-resistant structural design, balancing ultra-high water treatment throughput with stable filtration precision and long-term operational durability. It is compatible with standard large-diameter industrial water treatment pipeline systems, supports flexible modular parallel operation for scalable processing capacity, and features excellent corrosion and chemical resistance to adapt to complex raw water quality conditions with minimal pre-treatment. Easy to install, operate and maintain, the RCP045-60NPP serves as a cost-effective core filtration solution for medium and large-scale water treatment projects, realizing efficient water purification, wastewater recycling and brackish water desalination with low energy consumption and high resource utilization efficiency.

The RCP045-60NPP features a nominal filtration precision of 0.015 microns, with a uniformly microporous NPP membrane surface that eliminates filtration blind spots and local over-filtration even under high-flux operating conditions. This high-precision filtration capability effectively intercepts and removes suspended solids, colloidal particles, bacteria, algae, micro-particle impurities and macromolecular organic pollutants in raw water, ensuring that the effluent water quality stably meets national and industrial high-standard purification requirements. The filtration precision remains consistent with slight fluctuations in inlet water turbidity and impurity content, avoiding micro-impurity leakage and providing a reliable guarantee for subsequent water treatment processes or direct industrial and commercial water use.

Under standard operating conditions (25℃, rated working pressure), the RCP045-60NPP achieves a pure water flux of 60 L/m²·h, the core high-throughput advantage of this model, which is specially tailored for large-volume water treatment demands. The optimized wide-channel water flow design and high-permeability NPP membrane material effectively reduce flux attenuation caused by membrane fouling; within a reasonable range of water temperature changes (5℃-40℃) and inlet water quality fluctuations, the flux remains stable with a low attenuation rate (≤5% per month) during long-term continuous operation. This high and stable flux performance fully meets the large water volume demands of medium and large-scale industrial process water preparation, commercial centralized water supply, municipal tap water deep purification and industrial wastewater recycling systems.

The RCP045-60NPP delivers excellent salt rejection performance under standard operating parameters, with a 98.2% rejection rate for monovalent inorganic salt ions and a 99.3% rejection rate for divalent inorganic salt ions—levels that exceed conventional polypropylene membrane products of the same specification. The high-density selective separation layer of the novel NPP membrane material effectively blocks the passage of various salt ions and inorganic impurities while ensuring the smooth penetration of water molecules; the salt rejection rate remains stable (variation ≤0.5%) even with slight fluctuations in inlet water salinity (≤3000 mg/L) and operating pressure. This high salt rejection capability, combined with its high-flux performance, makes the product an ideal choice for high-throughput brackish water desalination, industrial pure water preparation and high-standard water softening treatment in industries with strict salt content limits.

During normal continuous operation at rated high flux and standard water temperature, the pressure drop of the RCP045-60NPP is strictly controlled within the range of 0.17-0.23 MPa. The product adopts a low-resistance internal structural design, including a smooth wide-diameter water inlet/outlet channel, an optimized porosity porous support layer and a streamlined filtration core layout, which minimizes water flow resistance in the high-flux filtration process and avoids excessive pressure accumulation. This low pressure drop performance effectively reduces the energy consumption of the water treatment system’s booster pump, lowers the overall operational energy cost of the system, and ensures that the membrane core is not damaged by excessive pressure. The pressure drop has no significant increase during the normal service life; a slight rise (≤0.05 MPa) is only observed when regular cleaning is required, which is easy to identify and handle, ensuring long-term stable system operation.

The Molecular Weight Cutoff of the RCP045-60NPP is accurately calibrated at 1200 Da (Daltons), a precise setting that enables selective interception of macromolecular impurities in water while allowing small molecule water and beneficial trace elements to pass through smoothly—even under high-flux operating conditions. This MWCO performance can effectively block organic macromolecules, colloidal substances, macromolecular polymers, protein impurities and polysaccharides with a molecular weight higher than 1200 Da, and is specially suitable for the separation and purification of water containing organic macromolecular pollutants in high-throughput scenarios. The accurate MWCO design balances high water treatment throughput with high purification effect, ensuring no unnecessary interception of small molecule substances and meeting the differentiated water quality requirements of various high-flow industrial and commercial application scenarios.

The core filtration membrane of the RCP045-60NPP is a multi-layer composite novel NPP membrane with a total thickness of 155 μm, consisting of a 23 μm dense selective separation layer (the core functional layer for high-precision filtration and high salt rejection), a 102 μm high-strength porous support layer (providing strong mechanical support for the membrane under high-flux and high-pressure 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 high-flux operation: the high-density selective separation layer ensures uncompromised filtration and salt rejection performance under high water flow velocity; the high-strength porous support layer enhances the membrane’s resistance to high pressure and water flow impact, avoiding membrane deformation or damage during long-term continuous operation; the anti-fouling protective layer is modified with special hydrophobic technology, which effectively reduces the adsorption of organic pollutants and microorganisms, extending the membrane’s service life.

Under standard operating conditions and strict adherence to the regular maintenance and cleaning schedule, the recommended replacement cycle of the RCP045-60NPP is 24-36 months. Considering its high-flux operating characteristics and complex industrial water quality conditions, the actual replacement cycle can be flexibly adjusted according to the actual inlet water quality and operating frequency: for raw water with low impurity content, low salinity and regular professional cleaning (1-2 times per month), the replacement cycle can be extended to 36 months; for raw water with high impurity content, high salinity and 24-hour continuous high-flux operation, the recommended replacement cycle is 24 months to ensure stable filtration precision, flux and salt rejection performance. The main indicators for replacement include a significant decrease in flux (≥20%), a sharp rise in pressure drop (≥0.1 MPa) or a noticeable decline in salt rejection rate (≥1%); the product’s modular integrated design makes the replacement process simple and fast, requiring no professional tools, and a single operator can complete the replacement within 30 minutes, minimizing system downtime.
