The RCP045-60SPP is a high-flux, industrial-grade water treatment filtration product engineered with advanced SPP (Super Polypropylene) membrane technology, meticulously optimized for high-throughput water purification, wastewater recycling and brackish water desalination in industrial, commercial and municipal scenarios. This model integrates a high-performance SPP filtration core with a reinforced, pressure-resistant and corrosion-proof structural design, achieving an optimal balance between ultra-high water treatment throughput, stable high-precision filtration and long-term operational durability. It is fully compatible with standard large-diameter industrial water treatment pipeline systems, supports flexible modular parallel operation for on-demand scalable processing capacity, and features excellent adaptability to complex raw water quality conditions with only simple pre-treatment required. Easy to install, operate and maintain, the RCP045-60SPP serves as a cost-effective and reliable core filtration solution for medium and large-scale water treatment projects, enabling efficient water resource utilization with low operational energy consumption and reduced maintenance costs.

The RCP045-60SPP boasts a nominal filtration precision of 0.02 microns, with a uniformly microporous SPP membrane surface that maintains consistent filtration performance and eliminates blind spots or local over-filtration even under continuous 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 for process water, drinking water and recycled water. The filtration precision remains unaltered with slight fluctuations in inlet water turbidity, impurity content and temperature, avoiding micro-impurity leakage and providing a solid and reliable guarantee for subsequent water treatment processes or direct industrial and commercial water use.

Under standard operating conditions (25℃, rated working pressure), the RCP045-60SPP achieves a pure water flux of 60 L/m²·h—the core high-throughput advantage of this model, exclusively tailored to meet the large-volume water treatment demands of medium and large-scale projects. The product’s optimized wide-channel water flow design and high-permeability SPP membrane material effectively minimize flux attenuation caused by membrane fouling; within a reasonable range of water temperature changes (5℃-40℃) and inlet water quality fluctuations, the flux remains highly stable with a low monthly attenuation rate (≤6%) during long-term continuous operation. This high and stable flux performance fully satisfies the large water volume demands of industrial process water preparation, commercial centralized water supply, municipal tap water deep purification and industrial wastewater recycling systems, without compromising the purification effect for throughput.

The RCP045-60SPP delivers excellent salt rejection performance under standard operating parameters, with a 98.0% rejection rate for monovalent inorganic salt ions and a 99.2% rejection rate for divalent inorganic salt ions—performance levels that surpass conventional polypropylene membrane products of the same specification. The high-density, high-selectivity separation layer of the super SPP membrane material effectively blocks the passage of various salt ions, inorganic impurities and scale-forming substances while ensuring the smooth and rapid penetration of water molecules; the salt rejection rate remains stable (variation ≤0.6%) even with slight fluctuations in inlet water salinity (≤3500 mg/L) and operating pressure. This outstanding 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 such as food and beverage, electronics and pharmaceutical processing.

During normal continuous operation at rated high flux and standard water temperature, the pressure drop of the RCP045-60SPP is strictly controlled within the range of 0.18-0.24 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 in the system. This low pressure drop performance effectively reduces the energy consumption of the water treatment system’s booster pump, significantly lowering the overall operational energy cost of the system, and at the same time 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 (≤0.06 MPa) is only observed when regular cleaning is required, which is easy to identify and handle, ensuring the long-term stable operation of the entire water treatment system.

The Molecular Weight Cutoff of the RCP045-60SPP is accurately calibrated at 1500 Da (Daltons), a precise setting that enables the 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 1500 Da, and is specially suitable for the separation and purification of water containing organic macromolecular pollutants in high-throughput industrial and commercial scenarios. The accurate MWCO design perfectly 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 application scenarios.

The core filtration membrane of the RCP045-60SPP is a multi-layer composite super SPP membrane with a total thickness of 160 μm, consisting of a 22 μm dense selective separation layer (the core functional layer for high-precision filtration and high salt rejection), a 108 μm high-strength porous support layer (providing strong mechanical support for the membrane under high-flux and high-pressure 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 high-flux operation: the high-density selective separation layer ensures uncompromised filtration and salt rejection performance even under high water flow velocity; the high-strength porous support layer is made of reinforced polypropylene material, enhancing the membrane’s resistance to high pressure and water flow impact, and avoiding membrane deformation or damage during long-term continuous operation; the anti-fouling protective layer is modified with special anti-adhesion and hydrophobic technology, which effectively reduces the adsorption of organic pollutants and microorganisms on the membrane surface.

Under standard operating conditions and strict adherence to the regular maintenance and cleaning schedule, the recommended replacement cycle of the RCP045-60SPP is 24-36 months. Considering its high-flux operating characteristics and the complex raw water quality conditions in industrial and municipal scenarios, 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 the stable operation of 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 entire replacement operation within 30 minutes, minimizing the downtime of the water treatment system.

The RCP045-60SPP has a number of outstanding product features that make it highly competitive in the high-flux water treatment market, combining advanced super SPP membrane technology with optimized functional design for high-throughput application scenarios.
