RCP030-60EPP Water Treatment Filter Cartridge Technical Specification

Product Introduction

The RCP030-60EPP is a high-performance enhanced polypropylene (EPP) water filter cartridge, engineered for low-medium flow coarse pre-filtration in small commercial, light industrial, rural small-scale and low-pressure water treatment scenarios. As a key coarse filtration product of the RCP030 series, it adopts food-grade high-density modified EPP raw materials and advanced large-pore gradient melt-blown forming technology, optimized with a 60EPP core structure to achieve an optimal balance of 60-micron coarse filtration precision, 30L/h stable low-medium flux, ultra-high dirt-holding capacity and compact structural design. Free of adhesives, heavy metals, plasticizers and organic leachables, the cartridge fully complies with FDA, NSF and international drinking water material safety standards, ensuring zero secondary pollution to water bodies. It is specially designed as the first-line coarse filtration barrier to intercept large suspended solids, 60-micron coarse particulate impurities, sediment, rust lumps and large colloidal aggregates in raw water, effectively reducing the heavy impurity load of subsequent precision filtration equipment such as mini RO membranes, ultrafiltration membranes and compact water purifiers. The product’s enhanced EPP large-pore structure is highly adaptable to raw water with high sediment and impurity content, perfectly matching the water quality characteristics of rural surface water, groundwater and industrial low-grade raw water treatment systems, and ensuring the stable operation of the entire water purification system.

Filtration Precision

The RCP030-60EPP features a graded large-pore coarse filtration structure with a nominal filtration precision of 60 microns and an absolute filtration precision of 65 microns. Its multi-layer gradient pore design consists of a smooth surface interception layer, an ultra-high-capacity impurity storage layer and a high-strength mechanical support layer, which can realize targeted and efficient capture of large impurities with particle sizes above 60 microns in low-medium flow water flow. The dense surface EPP layer effectively blocks coarse particulates, sediment lumps, rust and large colloidal aggregates that are easy to cause physical clogging and wear of subsequent miniature precision membrane elements, pipeline valves and water pumps; the inner ultra-high-capacity storage layer with large pore space can store a huge amount of intercepted impurities, avoiding rapid blockage of the cartridge and ensuring long-term stable filtration. This structural design ensures that the filtration precision remains stable and unattenuated throughout the entire service cycle, even under long-term continuous low-medium flow working conditions (≤30L/h) and variable low inlet pressure environments (0.06-0.2MPa).

Flux

Under the standard operating conditions (25℃ ambient temperature, 0.15MPa inlet pressure, pure water medium), the pure water flux of the RCP030-60EPP is stably set at 30 L/h (liters per hour), the core low-medium flow design advantage of this product. Within the recommended operating pressure range of 0.06-0.2MPa, the flux variation rate is less than 4%, maintaining ultra-stable output for small-scale water treatment systems with low and unstable inlet pressure; when the water temperature is in the range of 5-50℃ (the optimal working temperature for rural and light industrial small-scale water purification systems), the flux changes linearly with temperature and can be fully recovered when the temperature returns to the standard value. For actual raw water with turbidity ≤40 NTU (the recommended working turbidity for high-impurity coarse pre-filtration scenarios), the actual operating flux can still maintain more than 29 L/h, fully meeting the low-medium flow, stable water supply and coarse pre-filtration requirements of small commercial, light industrial, rural small-scale and mobile water treatment systems.

Salt Rejection Rate

As a low-medium flow enhanced polypropylene coarse filtration cartridge, the RCP030-60EPP is optimized for the physical interception of non-ionic salt contaminants, coarse colloidal salt particles, insoluble salt precipitates and salt-containing sediment aggregates with particle sizes above 60 microns, with a salt rejection rate of ≥99.8% for insoluble salt particulates and salt-containing colloidal aggregates with particle sizes above 60 microns. For soluble inorganic salts, it serves as a professional coarse pre-filtration component for small-scale desalination systems such as mini RO and compact NF membranes, which can effectively reduce the coarse particulate salt load in the feed water of subsequent small precision desalination membrane elements (with limited effective area). This avoids salt scaling and particulate fouling on the membrane surface, thus improving the overall salt rejection efficiency of the desalination system and extending the service life of membrane elements by more than 45%. In addition, the cartridge can intercept more than 99.5% of coarse macromolecular organic salts and salt-containing impurity lumps in low-medium flow water systems, further optimizing the feed water quality for subsequent precision purification equipment and reducing the maintenance frequency of the whole system.

Pressure Drop

Under the rated flux (30 L/h) and standard operating conditions, the initial pressure drop of the RCP030-60EPP is ≤0.005MPa, which is the ultra-low pressure drop advantage of the large-pore coarse filtration structure, significantly lower than that of conventional PP filter cartridges of the same series with smaller precision. This design realizes ultra-low energy consumption operation of low-medium flow water treatment systems, and no additional booster pump is needed even for low-pressure raw water supply scenarios such as rural tap water and gravity water supply. With the progress of filtration work and the gradual accumulation of intercepted coarse impurities, the pressure drop of the cartridge rises extremely slowly due to its ultra-high dirt-holding capacity and large-pore structure; the recommended maximum allowable operating pressure drop is 0.08MPa. When the pressure drop reaches this threshold, the cartridge needs to be cleaned or replaced in time to avoid excessive pressure loss leading to reduced water supply flow of small-scale systems, abnormal operation of subsequent precision equipment and even structural damage to the cartridge caused by pressure accumulation in the compact filter housing.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the RCP030-60EPP is precisely calibrated to 800,000 Daltons (Da), which is perfectly matched with its 60-micron coarse filtration precision and enhanced EPP large-pore gradient structure. This MWCO rating can effectively retain extra-large macromolecular organic matter, coarse colloidal particles, macromolecular impurity aggregates, organic polymer lumps and humic acid aggregates with molecular weight higher than 800,000 Da in low-medium flow water systems, while ensuring the unimpeded passage of water molecules, small-molecular inorganic substances, trace beneficial ions and small suspended particles (below 60 microns). It is specially designed for the coarse pre-filtration requirements of low-medium flow, low-pressure water treatment systems with high raw water impurity content, and can effectively reduce the large molecular contaminant load of subsequent miniature precision membrane elements, avoiding membrane clogging and improving the overall operation efficiency of small-scale purification systems by more than 35%.

Membrane Thickness

The RCP030-60EPP adopts a three-layer composite enhanced polypropylene membrane structure adapted to 60-micron large-pore coarse filtration and low-medium flow design, with a total effective membrane thickness of 22mm. The surface filtration layer (5mm) is a dense modified EPP membrane with large uniform pores, responsible for precision interception of 60-65 micron coarse particulates, with excellent wear resistance and anti-scouring performance suitable for raw water with high sediment and rust content; the middle transition support layer (12mm) is an ultra-high-capacity gradient pore EPP membrane, the core dirt-holding area of the cartridge, which undertakes secondary interception of large impurities and provides stable three-dimensional structural support for the surface layer, with huge internal space for storing sediment and lumpy impurities; the bottom base layer (5mm) is a high-density enhanced EPP membrane with high mechanical strength, enhancing the overall pressure resistance, extrusion resistance and impact resistance of the cartridge while ensuring the structural stability of the melt-blown large-pore structure. This scientific three-layer thickness distribution balances high coarse filtration efficiency, ultra-high dirt-holding capacity and moderate structural compactness, making the cartridge resistant to deformation and rupture under long-term low-pressure, low-medium flow and high-impurity raw water scouring conditions, and suitable for installation in small and medium-size standard filter housings (food-grade plastic/304 stainless steel).

Replacement Cycle

The recommended standard replacement cycle of the RCP030-60EPP is 7-10 months, formulated based on the standard low-medium flow coarse pre-filtration working conditions: raw water turbidity ≤40 NTU, suspended solids content ≤50 mg/L, and 10-16 hours of daily operation (matching small commercial/light industrial/rural use habits). For low-medium flow water treatment systems with extremely harsh water quality conditions (turbidity >40 NTU, suspended solids content >50 mg/L) such as rural surface water (river/lake water), groundwater with high sediment content and industrial low-grade raw water, the replacement cycle is shortened to 5-7 months according to the actual system pressure drop and water quality test results; for ultra-low-turbidity high-quality raw water pre-filtration scenarios (turbidity ≤10 NTU) such as laboratory pure water preparation and high-end small commercial drinking water purification, with regular simple backwashing (water flushing) and routine maintenance, the replacement cycle can be appropriately extended to 10-12 months, effectively reducing the use and maintenance costs of small-scale water treatment systems by more than 40%.
