RCP200-60NPP Water Treatment Filter Cartridge Technical Specification

Product Introduction

The RCP200-60NPP is a high-performance natural polypropylene (NPP) water filter cartridge, exclusively engineered for high-flow coarse pre-filtration in medium and large-scale industrial, commercial, municipal auxiliary and centralized water supply treatment scenarios. As a core high-flow natural material product of the RCP200 series, it adopts food-grade virgin natural polypropylene raw materials without any modified additives or recycled components, combined with advanced large-pore gradient melt-blown forming technology and a reinforced core structure, optimized with a 60NPP high-flow design to achieve an ideal balance of 60-micron coarse filtration precision, 200L/h stable high flux, ultra-high dirt-holding capacity and eco-friendly material properties. Manufactured with an adhesive-free integrated forming process, the cartridge is free of heavy metals, plasticizers, organic leachables and chemical modifiers, fully complying with FDA, NSF, EU REACH and industrial water treatment material standards, ensuring zero secondary pollution to water bodies and meeting the dual requirements of high-flow filtration efficiency and environmental protection. Designed as a key first-line coarse filtration barrier for high-flow raw water systems with high sediment and impurity content, it is dedicated to intercepting large suspended solids, 60-micron coarse particulate impurities, sediment lumps, rust and large colloidal aggregates in high-flow water flow, effectively reducing the heavy impurity load of subsequent precision filtration equipment such as industrial RO membranes, ultrafiltration membranes and large-scale water purifiers, and ensuring the stable, efficient and low-cost operation of the entire high-flow water treatment system. The pure natural PP structure features excellent chemical compatibility and easy recyclability, perfectly matching the environmental protection and large-flow operation needs of industrial and commercial water treatment scenarios.

Filtration Precision

The RCP200-60NPP features a reinforced 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 is crafted with high-flow optimized pure natural polypropylene melt-blown technology, consisting of a dense smooth surface interception layer, an ultra-high-capacity impurity storage layer and a high-strength reinforced mechanical support layer. This structure is specially designed for high-flow water dynamics, realizing targeted and efficient capture of all large impurities with particle sizes above 60 microns in 200L/h high-flow water flow, without impurity leakage caused by water flow scouring. The dense surface NPP layer effectively blocks coarse particulates, sediment lumps, rust and large colloidal aggregates that are easy to cause physical clogging, wear and pipeline scaling of subsequent industrial precision membrane elements, high-flow water pumps and valves; the inner ultra-high-capacity storage layer with uniform large pores and three-dimensional porous structure can store a huge amount of intercepted impurities, avoiding rapid blockage of the cartridge and ensuring long-term stable filtration performance. Even under long-term continuous high-flow working conditions (200L/h) and variable inlet pressure environments (0.1-0.3MPa), this structural design can keep the filtration precision stable and unattenuated throughout the entire service cycle, without precision degradation caused by material aging, water flow impact or additive loss.

Flux

Under the standard operating conditions (25℃ ambient temperature, 0.2MPa inlet pressure, pure water medium), the pure water flux of the RCP200-60NPP is stably set at 200 L/h (liters per hour), the core high-flow design advantage of this product. Within the recommended operating pressure range of 0.1-0.3MPa, the flux variation rate is less than 3%, maintaining ultra-stable high-flow water output for medium and large-scale industrial and commercial water treatment systems with variable inlet pressure. When the water temperature is in the range of 5-55℃ (the optimal working temperature for industrial, commercial and municipal auxiliary high-flow water purification systems), the flux changes linearly with temperature, and the flux recovery rate reaches 100% when the temperature returns to the standard value, without permanent flux loss caused by thermal deformation of pure natural PP materials. For actual raw water with turbidity ≤50 NTU (the recommended working turbidity for high-flow high-impurity coarse pre-filtration scenarios), the actual operating flux can still maintain more than 190 L/h, fully meeting the high-flow, stable water supply and coarse pre-filtration requirements of medium and large-scale industrial, commercial, municipal auxiliary and centralized water supply treatment systems.

Salt Rejection Rate

As a high-flow natural polypropylene coarse filtration cartridge, the RCP200-60NPP 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 eco-friendly coarse pre-filtration component for medium and large-scale industrial desalination systems such as industrial RO and large-scale NF membranes, which can effectively reduce the coarse particulate salt load in the feed water of subsequent high-precision desalination membrane elements (with large effective area but high sensitivity to coarse impurities), avoid 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 pure natural NPP material structure with no chemical additives can intercept more than 99.5% of coarse macromolecular organic salts and salt-containing impurity lumps in high-flow water systems without chemical reaction with salt substances or ion exchange, further optimizing the feed water quality for subsequent precision purification equipment and significantly reducing the backwashing and maintenance frequency of the whole system.

Pressure Drop

Under the rated flux (200 L/h) and standard operating conditions, the initial pressure drop of the RCP200-60NPP is ≤0.01MPa, the ultra-low pressure drop advantage of the high-flow optimized large-pore coarse filtration structure made of pure natural polypropylene. This value is significantly lower than that of modified PP filter cartridges of the same precision and flow rate, realizing ultra-low energy consumption operation of high-flow water treatment systems and effectively reducing the power consumption of high-flow water pumps. Even for medium-pressure raw water supply scenarios such as municipal tap water and industrial raw water pipelines without additional booster pumps, the cartridge can ensure unobstructed high-flow water flow without causing excessive pressure loss of the whole system. With the progress of filtration work and the gradual accumulation of a large amount of intercepted coarse impurities, the pressure drop of the cartridge rises extremely slowly due to its ultra-high dirt-holding capacity, uniform large-pore structure and high-flow optimized water channel design; the recommended maximum allowable operating pressure drop is 0.09MPa. 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 high-flow systems, abnormal operation of subsequent industrial precision equipment and even structural damage to the cartridge caused by pressure accumulation in high-flow filter housings.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the RCP200-60NPP is precisely calibrated to 800,000 Daltons (Da), which is perfectly matched with its 60-micron coarse filtration precision, high-flow optimized structure and natural polypropylene large-pore gradient melt-blown forming technology. This MWCO rating is customized for the physical interception characteristics and high-flow water dynamics of pure natural PP materials, which 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 high-flow water systems. At the same time, it ensures the unimpeded passage of water molecules, small-molecular inorganic substances, trace beneficial ions and small suspended particles (below 60 microns), without affecting the normal high water permeability of the system due to material adsorption or water channel blockage. It is specially designed for the coarse pre-filtration requirements of high-flow, medium-pressure water treatment systems with high raw water impurity content, and can effectively reduce the large molecular contaminant load of subsequent industrial precision membrane elements, avoiding membrane clogging and improving the overall operation efficiency of medium and large-scale purification systems by more than 40%.

Membrane Thickness

The RCP200-60NPP adopts a reinforced three-layer composite natural polypropylene membrane structure adapted to 60-micron large-pore coarse filtration and 200L/h high-flow design, with a total effective membrane thickness of 30mm. The entire membrane structure is made of food-grade virgin natural polypropylene without any modified additives or recycled materials, ensuring the purity, environmental protection and structural strength of the material to adapt to high-flow water impact. The surface filtration layer (6mm) is a dense reinforced natural PP membrane with uniform large pores and high wear resistance, responsible for precision interception of 60-65 micron coarse particulates, with excellent anti-scouring performance suitable for high-flow raw water with high sediment and rust content; the middle transition support layer (18mm) is an ultra-high-capacity gradient pore natural PP 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 a huge internal porous space for storing a large amount of sediment, rust lumps and other coarse impurities in high-flow water flow; the bottom base layer (6mm) is a high-density high-strength natural PP membrane combined with a reinforced internal core, enhancing the overall pressure resistance, extrusion resistance and anti-impact performance of the cartridge while ensuring the structural stability of the melt-blown large-pore structure under high-flow working conditions. This scientific three-layer thickness distribution with reinforced design balances high coarse filtration efficiency, ultra-high dirt-holding capacity, high structural strength and high-flow adaptability, making the cartridge resistant to deformation, rupture and delamination under long-term medium-pressure, high-flow and high-impurity raw water scouring conditions, and suitable for installation in standard large-flow industrial filter housings (304/316L stainless steel/food-grade reinforced plastic).

Replacement Cycle

The recommended standard replacement cycle of the RCP200-60NPP is 8-12 months, formulated based on the standard high-flow coarse pre-filtration working conditions: raw water turbidity ≤50 NTU, suspended solids content ≤60 mg/L, and 24-hour continuous operation (matching industrial, commercial and municipal auxiliary high-flow water treatment use habits). The pure natural PP material with reinforced structure has excellent anti-aging and anti-scouring performance, which can maintain stable structural and filtration performance under long-term continuous high-flow water immersion and scouring conditions. For high-flow water treatment systems with extremely harsh water quality conditions (turbidity >50 NTU, suspended solids content >60 mg/L) such as industrial raw water, municipal surface water (river/lake water) and groundwater with high sediment content, the replacement cycle is shortened to 6-8 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 ≤15 NTU) such as commercial centralized drinking water supply, high-end industrial pure water preparation and municipal auxiliary water purification, with regular backwashing (water/gas mixed flushing) and professional routine maintenance, the replacement cycle can be appropriately extended to 12-15 months, effectively reducing the use and maintenance costs of medium and large-scale high-flow water treatment systems by more than 40%.
