Product Introduction
The RCP045-20EPP is a compact, high-performance water treatment unit engineered with premium EPP (Enhanced Polypropylene) filter media, tailored for small-to-medium flow commercial and light industrial water purification, pre-treatment and process water preparation demands. This system integrates a precision filtration structure with a rugged, space-saving modular design, optimized to efficiently remove suspended solids, colloidal particles, organic contaminants and partial dissolved salts from tap water, surface water and low-concentration groundwater sources. Equipped with built-in pressure regulation and anti-clogging components, it features tool-free filter chamber access for effortless installation, routine maintenance and backwashing—no specialized technical skills required for daily operation. Suitable for standalone use or as a critical pre-treatment module for small-scale reverse osmosis (RO), ultrafiltration (UF) and UV disinfection systems, the RCP045-20EPP delivers consistent, high-quality treated water with low energy consumption and minimal operational costs, making it an ideal solution for compact workspace and medium-pressure water treatment scenarios.
Filtration Precision
The RCP045-20EPP achieves a 0.2-micron precision filtration rating, which effectively captures fine suspended particles, bacteria, algae, colloidal substances and micro-scale insoluble impurities that cause equipment scaling, pipeline clogging and water quality deterioration. This professional-grade filtration capability ensures treated water meets strict industry clarity and purity standards for light industrial and commercial applications, striking a perfect balance between contaminant removal efficiency and operational simplicity for small-to-medium flow water processing needs.
Flux
Under standard operating conditions (25°C inlet water temperature, 32 psi inlet pressure, feed water turbidity <8 NTU and pH 5.0-9.0), the RCP045-20EPP features a nominal flux rate of 20 gallons per minute (GPM). This flux is precisely calibrated for small-to-medium flow scenarios, ensuring efficient water throughput without compromising filtration quality. Thanks to the high porosity and optimized fiber structure of EPP filter media, the flux remains stable even with minor fluctuations in feed water temperature and turbidity, eliminating the need for frequent flow adjustment and ensuring consistent water output for continuous operation.
Salt Rejection Rate
Equipped with a high-performance selective EPP composite filtration membrane, the RCP045-20EPP achieves a 95% salt rejection rate for monovalent salts (e.g., sodium chloride, potassium chloride) and a 97% salt rejection rate for divalent salts (e.g., calcium carbonate, magnesium sulfate, calcium sulfate). This excellent selective salt rejection performance effectively reduces total dissolved solids (TDS) content in treated water, significantly improving water purity and making it suitable for light industrial process water, commercial drinking water and small-scale boiler feed water pre-treatment applications.
Pressure Drop
The pressure drop across the RCP045-20EPP system is strictly controlled at a low range of 3–4 psi under nominal 20 GPM flux conditions. This minimal pressure loss is attributed to the high permeability of enhanced polypropylene filter media and the streamlined internal flow path design, which minimizes water flow resistance and eddy current generation. A low pressure drop not only reduces the energy consumption of water pumping equipment and lowers operational costs, but also prevents excessive pressure buildup inside the system, thereby extending the service life of membrane elements, seal components and other key structural parts.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the RCP045-20EPP is precisely rated at 15,000 Daltons. This means the system can effectively retain and separate organic macromolecules with a molecular weight of 15,000 Daltons or higher, such as humic acids, industrial dye residues, protein contaminants and polysaccharides, while allowing water molecules, small inorganic ions and low-molecular-weight organic substances to pass through unimpeded. This accurate selective separation capability makes the system an ideal choice for small-scale industrial wastewater treatment and pre-treatment for RO/UF systems, effectively preventing membrane fouling and extending the service life of downstream water treatment components.
Membrane Thickness
The filtration membrane of the RCP045-20EPP has a total optimized thickness of 180 microns, consisting of a 140-micron porous EPP support layer and a 40-micron dense selective filtration layer. The thick, high-strength enhanced polypropylene support layer provides excellent mechanical rigidity and pressure resistance, effectively preventing membrane deformation, rupture or damage under medium operating pressure and continuous small-to-medium flow conditions. The dense, uniformly structured selective layer is the core component ensuring the system’s high filtration precision and efficient salt rejection performance, maintaining high water permeability while blocking contaminants to realize stable 20 GPM flux operation.
Replacement Cycle
The recommended replacement cycle for the EPP filter elements of the RCP045-20EPP is 8–10 months under normal operating conditions (feed water turbidity <5 NTU, regular backwashing every 72 hours and standard feed water quality maintenance). For feed water with high turbidity (>10 NTU) or high organic contaminant content, the replacement cycle can be appropriately shortened to 5–6 months to maintain the system’s optimal filtration efficiency, stable flux and high-quality water output. Regular and timely replacement of filter elements is critical to prevent contaminant accumulation, membrane clogging, abnormal pressure drop rise and a decline in treated water quality, and also avoids irreversible damage to the system caused by excessive fouling.
