The RCP100-60EPP is a high-performance large-specification water treatment filtration product engineered with advanced Enhanced Polypropylene (EPP) membrane technology, specifically optimized for 60 L/m²·h high flux and high-precision purification in medium and large-scale industrial, municipal, commercial and environmental protection water treatment scenarios with massive water volume demands. This model integrates an expanded high-efficiency filtration area with a high-selectivity, anti-fouling EPP membrane core, and is equipped with a reinforced industrial-grade anti-corrosion and pressure-resistant structural housing, achieving a perfect balance between ultra-stable high throughput and reliable high-precision purification—this core advantage is tailored for large-scale water treatment projects that pursue both processing efficiency and strict effluent quality standards. It is fully compatible with standard industrial large-diameter water treatment pipeline setups, supports flexible modular parallel and series operation for on-demand system capacity expansion and precision adjustment, and features excellent anti-pollution, anti-fouling and broad water quality adaptability, enabling stable long-term operation with complex raw water sources after simple targeted pre-treatment (2 μm coarse filtration). Easy to install, operate and maintain, the RCP100-60EPP serves as a cost-effective, high-reliability core filtration solution for large-scale high-flux water purification projects, realizing industrial process water preparation, municipal tap water deep purification, large-flow wastewater resource reuse and commercial high-standard water supply with low operational energy consumption and consistent long-term performance.

The RCP100-60EPP features an ultra-high nominal filtration precision of 0.01 microns, with a nanoscale uniformly microporous EPP membrane surface that is formed by advanced phase inversion technology, ensuring consistent pore size distribution and eliminating filtration blind spots even under continuous 60 L/m²·h high-flux operation. This high-precision filtration capability can effectively intercept and remove submicron suspended solids, colloidal particles, bacteria, algae spores, micro-particle impurities and macromolecular organic pollutants in raw water, ensuring that the effluent water quality stably meets national and industrial Grade II ultra-pure water standards, as well as the strict purity requirements of industrial production, municipal drinking water and commercial high-standard water supply. The filtration precision remains unaltered with slight fluctuations in inlet water turbidity (≤12 NTU), temperature (5℃-35℃) and impurity content within a reasonable range, avoiding micro-impurity leakage and providing a solid and reliable technical guarantee for subsequent water treatment processes or direct use in various large-flow water demand scenarios.

Under standard operating conditions (25℃, rated working pressure), the RCP100-60EPP achieves a pure water flux of 60 L/m²·h—a high-flux design exclusively tailored for large-scale water treatment projects with massive water volume demands, breaking the traditional trade-off between high throughput and purification precision of polypropylene membrane products. The product’s optimized low-resistance wide water flow channel design and high-permeability EPP membrane material effectively minimize flux attenuation caused by membrane fouling; within the normal operating range (water temperature 5℃-35℃, inlet water turbidity ≤12 NTU), the flux remains highly stable with a monthly attenuation rate of ≤4.5% during long-term continuous operation. This ultra-stable high-flux performance fully meets the large-volume water demand of medium and large-scale industrial production lines, municipal centralized water supply systems, commercial high-standard water supply networks and large-flow wastewater treatment projects, without sacrificing purification precision for increased water output efficiency, and effectively improves the overall treatment capacity of large-scale water treatment systems by more than 50% compared with medium-flux models of the same series.

The RCP100-60EPP delivers excellent salt rejection performance under standard high-flux operating parameters, with a 98.7% rejection rate for monovalent inorganic salt ions and a 99.4% rejection rate for divalent inorganic salt ions—performance levels that surpass conventional EPP membrane products of the same specification and set a high industry standard for high-flux polypropylene filtration products. The ultra-dense, high-purity selective separation layer of the enhanced EPP membrane material forms an efficient ion barrier with strong molecular 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 even under 60 L/m²·h high-flux operation. The salt rejection rate remains stable (variation ≤0.35%) even with slight fluctuations in inlet water salinity (≤2800 mg/L) and operating pressure, making the product an ideal core filtration choice for large-scale pure water preparation, high-standard brackish water desalination and industrial process water softening in industries with strict salt content limits such as electronic component manufacturing, food and beverage deep processing, pharmaceutical bulk drug production and new energy battery manufacturing.

During normal continuous operation at rated 60 L/m²·h high flux and standard water temperature (25℃), the pressure drop of the RCP100-60EPP is strictly controlled within the low range of 0.12-0.17 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 high-flux filtration process to the greatest extent. This low pressure drop performance for high-flux operation 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, 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 (≤0.04 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-flux water treatment system.

The Molecular Weight Cutoff of the RCP100-60EPP is accurately calibrated at 800 Da (Daltons), a precise setting tailored for large-scale 60 L/m²·h high-flux water treatment scenarios, which enables the selective interception of medium and large molecular weight impurities in water while allowing water molecules and beneficial small inorganic molecules to pass through smoothly—even under continuous high-flux operation. This optimized MWCO performance can effectively block organic medium molecules, colloidal substances, medium-molecular-weight polymers, protein impurities, polysaccharides and other micro-pollutants with a molecular weight higher than 800 Da, and is specially suitable for the high-precision separation and purification of water containing medium-molecular-weight organic pollutants in large-scale industrial production, municipal water supply and large-flow wastewater treatment. The accurate MWCO design perfectly combines high-flux operation with high purification precision, ensures high-standard effluent water quality, and meets the differentiated large-scale high-precision water quality requirements of various industrial, commercial and municipal application scenarios.

The core filtration membrane of the RCP100-60EPP is a multi-layer composite enhanced EPP membrane with a total thickness of 170 μm, scientifically composed of three functional layers that are exclusively optimized for 60 L/m²·h high-flux and high-precision operation: a 30 μm ultra-dense selective separation layer (the core functional layer for high-precision filtration and high salt rejection, made of high-purity EPP material with advanced nanoscale pore formation technology, ensuring uncompromised purification performance under high water flow velocity); a 110 μm high-strength porous support layer (providing super strong mechanical support and pressure resistance for the membrane under high-flux and pressure-stable working conditions, adopting a reinforced cross-linked polypropylene structure with optimized porosity and pore size distribution to avoid membrane deformation and damage caused by high water flow impact); and a 30 μm anti-fouling protective layer (modified with special hydrophilic and anti-adhesion technology, reducing membrane surface pollution and mechanical wear, and inhibiting the adsorption of organic pollutants and microorganisms to slow down fouling rate under high-flux operation). The three-layer thickness and material optimization design ensure the membrane’s long-term structural stability and high purification efficiency while maintaining excellent water permeability, which is the key to realizing the balance between high flux and high precision of the product.

Under standard operating conditions and strict adherence to the regular maintenance and cleaning schedule, the recommended replacement cycle of the RCP100-60EPP is 24-36 months—an extended service life specially designed for 60 L/m²·h high-flux, large-scale operating scenarios, far longer than conventional low-flux polypropylene membrane filtration products. 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 deep cleaning (1-2 times per quarter), the replacement cycle can be extended to 36 months; for raw water with moderate impurity content and 24-hour continuous high-flux operation, the recommended replacement cycle is 24 months to ensure the stable operation of high filtration precision, flux and salt rejection performance; for raw water with relatively high impurity content, the cycle can be appropriately shortened to 20-24 months based on real-time detection data of water quality and operating parameters. The main quantitative indicators for replacement include a significant decrease in flux (≥20%), a sharp rise in pressure drop (≥0.07 MPa) or a noticeable decline in salt rejection rate (≥0.6%); 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 40 minutes, minimizing the downtime of the large-scale high-flux water treatment system and ensuring the continuous operation of industrial production and municipal water supply.
