RCP045-20VPP Water Treatment System

Product Introduction

The RCP045-20VPP is a compact, high-purity water treatment unit engineered with premium VPP (Virgin Polypropylene) filter media, exclusively designed for small-to-medium flow commercial, light industrial and high-standard civil water purification, pre-treatment and process water preparation scenarios. This system integrates a precision filtration structure with a space-saving, corrosion-resistant modular design, optimized to efficiently remove suspended solids, colloidal particles, organic micro-contaminants and partial dissolved salts from tap water, surface water and low-concentration groundwater without introducing secondary pollution. Equipped with built-in pressure stabilization and anti-clogging components, it features a quick-release filter chamber enabling tool-free installation, routine maintenance and backwashing—no specialized technical skills are required for daily operation. Made with food-grade and medical-grade compatible materials, the RCP045-20VPP is suitable for standalone use or as a key pre-treatment module for small-scale reverse osmosis (RO), ultrafiltration (UF) and UV disinfection systems. It delivers consistent, high-quality treated water with low energy consumption and minimal operational costs, making it an ideal filtration solution for compact workspaces with high water purity requirements in commercial, light industrial and high-end civil settings.

Filtration Precision

The RCP045-20VPP achieves a 0.1-micron ultra-high precision filtration rating, which can effectively capture ultra-fine suspended particles, bacteria, algae, colloidal substances, micro-scale insoluble impurities and even partial virus-like particles that cause pipeline clogging, equipment scaling and water quality deterioration. This top-tier filtration precision ensures the treated water meets stringent food-grade, pharmaceutical-grade and high-standard civil drinking water purity standards, striking an optimal balance between ultra-fine contaminant removal and stable water throughput for small-to-medium flow processing needs.

Flux

Under standard operating conditions (25°C inlet water temperature, 28 psi inlet pressure, feed water turbidity <5 NTU and pH value 5.0-9.0), the RCP045-20VPP features a nominal flux rate of 20 gallons per minute (GPM). This flux is precisely calibrated for small-to-medium flow water treatment scenarios with high purity demands, ensuring efficient water output without compromising the ultra-high filtration precision of the VPP media. Thanks to the high porosity and uniform fiber structure of virgin polypropylene filter media, the flux remains stable even with minor fluctuations in feed water temperature, turbidity and pressure, eliminating the need for frequent flow adjustment and ensuring continuous, consistent high-purity water supply for daily operation.

Salt Rejection Rate

Equipped with a high-performance selective VPP composite filtration membrane, the RCP045-20VPP achieves a 97% salt rejection rate for monovalent salts (e.g., sodium chloride, potassium chloride) and a 99% salt rejection rate for divalent salts (e.g., calcium carbonate, magnesium sulfate, calcium sulfate). This exceptional selective salt rejection performance effectively reduces the total dissolved solids (TDS) content in treated water, significantly improving water purity and taste. It makes the system suitable for high-standard commercial drinking water, food-grade process water, light pharmaceutical auxiliary water and small-scale boiler feed water pre-treatment applications with strict salt content requirements.

Pressure Drop

The pressure drop across the RCP045-20VPP system is strictly controlled at a low range of 2–3 psi under nominal 20 GPM flux conditions. This minimal pressure loss is attributed to the high permeability and large specific surface area of virgin polypropylene filter media, as well as the streamlined hydromechanical internal flow path design that minimizes water flow resistance and eddy current generation. A low pressure drop not only drastically 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, food-grade seal components and other key structural parts.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the RCP045-20VPP is precisely rated at 10,000 Daltons. This means the system can effectively retain and separate organic macromolecules with a molecular weight of 10,000 Daltons or higher, such as humic acids, industrial dye residues, protein contaminants, polysaccharides and macromolecular organic pollutants, while allowing water molecules, small inorganic ions and low-molecular-weight harmless organic substances to pass through unimpeded. This accurate selective separation capability makes the system an ideal choice for high-standard small-scale wastewater treatment and pre-treatment for small RO/UF systems in food and pharmaceutical industries, effectively preventing membrane fouling and extending the service life of downstream high-precision water treatment components.

Membrane Thickness

The filtration membrane of the RCP045-20VPP has a total optimized thickness of 150 microns, consisting of a 115-micron porous VPP support layer and a 35-micron dense selective filtration layer. Both layers are made of high-purity virgin polypropylene without any recycled materials, ensuring no secondary pollution and excellent chemical stability. The thick, high-strength virgin polypropylene support layer features a uniform three-dimensional fiber structure, providing excellent mechanical rigidity, pressure resistance and structural stability, which can effectively prevent membrane deformation, rupture or damage under medium operating pressure and continuous small-to-medium flow conditions. The dense and uniformly structured selective layer is the core component that ensures the system’s ultra-high filtration precision and efficient salt rejection performance, and it maintains high water permeability while blocking ultra-fine contaminants, which is the key to realizing the stable 20 GPM flux operation of the system with 0.1-micron precision.

Replacement Cycle

The recommended replacement cycle for the VPP filter elements of the RCP045-20VPP 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 5–7 months to maintain the system’s optimal filtration efficiency, stable flux and high-quality water output. As the filter media is made of pure virgin polypropylene, 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 it also helps to avoid irreversible damage to the system caused by excessive fouling and ensure the non-toxic and harmless performance of the filtration system.
