RCP045-40SPP High-Efficiency Water Treatment Filtration Module for Industrial & Commercial Purification Systems

The RCP045-40SPP is a professionally engineered water treatment filtration product, designed with advanced SPP membrane material technology and a highly integrated structural layout for efficient and stable water purification across commercial and industrial scenarios. This model is optimized for balanced performance, durability and ease of operation, featuring a corrosion-resistant housing and a high-performance SPP filtration core that adapts to diverse raw water quality conditions with minimal pre-treatment requirements. It is compatible with standard water treatment pipeline systems, supports modular installation and parallel operation, and requires no complex professional debugging, making it a reliable and cost-effective filtration solution for medium and small-scale water treatment projects and continuous water processing operations.

The RCP045-40SPP delivers superior nominal filtration precision of 0.02 microns, with a uniform pore size distribution across the entire SPP membrane surface that eliminates filtration blind spots and local over-filtration. This high-precision filtration capability effectively intercepts suspended solids, colloidal particles, bacteria, algae, micro-particles and other harmful impurities in water, ensuring that the effluent water quality stably meets national and industrial water purification standards. Even under variable inlet water impurity content, the filtration precision remains consistent, avoiding the leakage of micro-impurities and providing a stable guarantee for subsequent water treatment processes or direct water use.

Under standard operating conditions (25℃, rated working pressure), the RCP045-40SPP features a pure water flux of 40 L/m²·h, a design that balances high water treatment throughput with long-term membrane stability. The optimized water flow channel structure reduces flux attenuation caused by membrane fouling, and the flux remains stable within a reasonable range of water temperature changes (5℃-35℃) and inlet water turbidity fluctuations. This stable flux performance meets the actual water volume demands of commercial water supply, industrial process water preparation and wastewater recycling systems, without the need for frequent system adjustment to maintain water output.

The RCP045-40SPP achieves excellent salt rejection performance under standard operating parameters, with a 98.0% rejection rate for monovalent inorganic salt ions and a 99.0% rejection rate for divalent inorganic salt ions. The special selective separation layer of the SPP membrane material effectively blocks the passage of salt ions while ensuring the smooth penetration of water molecules, and the salt rejection rate remains stable even with slight fluctuations in inlet water salinity and operating pressure. This high salt rejection capability makes the product suitable for desalination of brackish water, pure water preparation and high-standard water softening treatment, meeting the water quality requirements of industries with strict salt content limits such as food and beverage, electronics and pharmaceutical processing.

During normal continuous operation at rated flux and standard water temperature, the pressure drop of the RCP045-40SPP is strictly controlled within the range of 0.16-0.21 MPa. The product adopts a low-resistance internal structural design, including a smooth water inlet/outlet channel and a porous support layer with optimized porosity, which minimizes water flow resistance in the filtration process. The low pressure drop performance reduces the energy consumption of the water treatment system’s booster pump, lowers the overall operational energy cost of the system, and avoids excessive pressure accumulation that may cause membrane damage. The pressure drop has no significant increase during the normal service life, and only a slight rise occurs when regular cleaning is required, which is easy to identify and handle.

The Molecular Weight Cutoff of the RCP045-40SPP 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. This MWCO performance can effectively block organic macromolecules, colloidal substances, macromolecular polymers and protein impurities with a molecular weight higher than 1500 Da, and is suitable for the separation and purification of water containing organic macromolecular pollutants. The accurate MWCO design ensures that the product does not cause unnecessary interception of small molecule substances, balancing water purification effect and water component rationality, and meeting the differentiated water quality requirements of different application scenarios.

The core filtration membrane of the RCP045-40SPP is a multi-layer composite SPP membrane with a total thickness of 160 μm, consisting of a 22 μm dense selective separation layer (the core functional layer for filtration and salt rejection), a 108 μm porous support layer (providing strong mechanical support for the membrane) and a 30 μm anti-fouling protective layer (reducing membrane surface pollution and mechanical damage). The multi-layer thickness design balances the product’s filtration precision, water permeability, pressure resistance and anti-fouling performance: the dense selective layer ensures high-efficiency impurity and salt rejection, the thick porous support layer enhances the membrane’s resistance to high pressure and water flow impact, and the protective layer effectively extends the membrane’s service life by reducing pollutant adsorption and physical wear.

Under standard operating conditions and strict adherence to the regular maintenance and cleaning schedule, the recommended replacement cycle of the RCP045-40SPP is 24-36 months. 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 turbidity 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 operation, the recommended replacement cycle is 24 months to ensure stable filtration performance and effluent water quality. A slight decrease in flux or a significant rise in pressure drop is the main indicator for replacement, and the modular design makes the replacement process simple and fast, reducing system downtime.

The RCP045-40SPP has a number of outstanding product features that make it highly competitive in the water treatment market. First, it adopts food-grade and industrial-grade dual-certified SPP membrane materials, which are non-toxic, odorless, and have no secondary pollution to water quality, meeting the safety and environmental protection requirements of food, pharmaceutical and drinking water treatment. Second, it features enhanced anti-fouling performance: the membrane surface is modified with special anti-fouling technology, which reduces the adsorption of organic matter, microorganisms and scale-forming substances, lowers the cleaning frequency (only 1-2 times of regular cleaning per month under standard conditions), and reduces maintenance costs. Third, the product has excellent pressure resistance and structural stability, able to operate stably under a working pressure range of 0.7-1.2 MPa, and resistant to short-term pressure fluctuations without membrane deformation or damage. Fourth, it has the advantage of easy installation and maintenance: the modular integrated design allows a single operator to complete installation, disassembly and replacement in a short time without professional tools, reducing the labor cost of system operation and maintenance. Fifth, it has wide water quality adaptability: after simple pre-treatment (such as coarse filtration), it can be used for the treatment of surface water, groundwater, tap water, brackish water and industrial secondary water with different quality characteristics. Sixth, it supports modular parallel operation, and multiple RCP045-40SPP products can be connected in parallel to form a large-flow water treatment system, meeting the water volume demands of large-scale projects and realizing flexible expansion of system processing capacity.
