Large PP Wound Filter Cartridge: Universal Replacement for Vertical and Horizontal Filters
Product Introduction
This large PP wound filter cartridge is a heavy-duty industrial filtration component engineered for universal replacement in vertical and horizontal filter housings across industrial water treatment and fluid filtration systems, tailored to the large-flow, high-load operating characteristics of industrial-grade filter equipment. Crafted from high-strength industrial-grade polypropylene (PP) resin via a high-precision dense spiral winding process on a reinforced thickened PP inner support core, it features an adhesive-free integral forming structure and an oversized graded porous filtration layer with expanded effective filtration area—designed to match the internal dimensional specifications of standard large vertical and horizontal filter housings (including single/multi-core configurations). Its core function is to efficiently remove large volumes of insoluble solid particulate impurities such as sediment, rust, scale debris, suspended solids and mechanical particulates from industrial process water, circulating water, raw water and other industrial fluids, protecting downstream production equipment, heat exchangers, pumps and precision filtration systems from blockage and wear, while ensuring continuous and stable filtration performance of vertical/horizontal filter units. Compliant with industrial water treatment material standards, it exhibits excellent structural stability, chemical resistance and anti-scouring performance under long-term large-flow operation, causes no secondary pollution to the filtered medium, and is a high-adaptability, universal replacement filtration core for petrochemical, power, metallurgy, manufacturing and municipal water treatment industries using vertical or horizontal filter housings. As a direct replacement part, it perfectly matches the installation interface and filtration demand of mainstream industrial vertical/horizontal filters, eliminating the need for housing modification and reducing maintenance downtime.
Filtration Precision
This large PP wound filter cartridge offers a full range of nominal filtration precision options from 5μm to 100μm, scientifically calibrated for the differentiated impurity removal demands of vertical and horizontal filter housings in various industrial scenarios, with each precision grade optimized for large-flow filtration efficiency. The 5μm/10μm high-precision options achieve over 98% interception of fine particulate impurities, suitable for vertical/horizontal filters in high-purity process water systems (e.g., electronic manufacturing, pharmaceutical production) and precision fluid filtration, ensuring the removal of micro-scale contaminants that damage precision equipment; the 20μm/30μm/50μm medium-precision options (the most commonly used for industrial general filtration) realize 95%+ interception of medium and coarse particulates, applicable to vertical/horizontal filters in industrial circulating water, cooling water and raw water pretreatment systems, balancing large-flow supply and efficient impurity removal; the 80μm/100μm coarse-precision options are designed for heavy-impurity fluid filtration, intercepting bulky solid contaminants in high-turbidity industrial water and process fluids, reducing the load of large vertical/horizontal filter units and avoiding rapid cartridge blockage. All precision grades are manufactured with a uniform winding process and strict pore size control, ensuring consistent and stable filtration performance without precision deviation under the high-pressure, large-flow scouring conditions of vertical/horizontal filters, and each precision grade is compatible with both vertical and horizontal filter housing configurations—realizing true universal replacement for different filter types and impurity removal requirements.
Flux
Under the standard industrial operating conditions of 25℃ ambient temperature and 0.25MPa inlet pressure (the typical working pressure of industrial vertical and horizontal filter housings), the nominal flux of this large PP wound filter cartridge is oversized and calibrated for the large-flow characteristic of industrial filter equipment, with flux performance positively correlated with filtration precision and optimized via the expanded effective filtration area of the oversized cartridge structure. For the mainstream industrial precision grades, the nominal flux of a single cartridge is as follows: 5μm (40-50 L/min), 10μm (50-60 L/min), 20μm (70-80 L/min), 30μm (80-90 L/min), 50μm (90-100 L/min), 80μm (100-120 L/min), 100μm (120-150 L/min). The oversized structural design maximizes the effective filtration area, significantly increasing flux compared with standard-sized PP wound filter cartridges, and fully adapting to the large-flow filtration demand of vertical and horizontal filters in industrial systems (including continuous 24-hour operation). For multi-core vertical/horizontal filter housings, the total system flux can be linearly scaled up by increasing the number of cartridges, meeting the ultra-large-flow filtration requirements of large-scale industrial production lines and municipal water treatment projects. The optimized internal flow channel structure with a smooth through-hole design minimizes water flow resistance for all precision grades, ensuring stable flux during the entire service life, avoiding flux attenuation caused by impurity accumulation, and ensuring that the filtered medium supply of vertical/horizontal filter units matches the industrial production load demand. Even under the high-precision 5μm/10μm configuration, the oversized filtration area maintains a high flux level, eliminating the need for excessive parallel cartridges and saving the internal space of vertical/horizontal filter housings.
Salt Rejection Rate
As a heavy-duty physical filtration component dedicated to particulate impurity removal in vertical and horizontal filter housings, this large PP wound filter cartridge—regardless of the selected filtration precision (5μm-100μm)—is designed exclusively for particle size-based interception of insoluble solid contaminants (sediment, rust, suspended solids, mechanical particulates) in industrial fluids and water systems. It has no functional design for ion separation, desalination or soluble salt removal, and therefore has no salt rejection rate index for all precision grades and configurations. All dissolved inorganic salts, metal ions, small molecule soluble substances, industrial fluid additives, dissolved solids (TDS) and other soluble components in the filtered medium pass smoothly through the cartridge body and enter the downstream system. This functional positioning is highly consistent with the core filtration demand of industrial vertical and horizontal filters: focusing on the removal of physical particulate impurities that cause equipment blockage, wear and system failure, without altering the soluble ion composition and chemical balance of the industrial fluid or water body. It avoids unnecessary interference with the chemical properties (e.g., pH, additive concentration, TDS) of process water and industrial fluids required for production, ensuring that the filtered medium fully meets the operational requirements of downstream industrial production processes and equipment, and is applicable to both desalination and non-desalination water treatment systems using vertical/horizontal filter housings.
Pressure Drop
The pressure drop performance of this large PP wound filter cartridge is optimized for the large-flow, high-pressure operating environment of industrial vertical and horizontal filter housings, with the initial pressure drop strictly controlled and the maximum allowable operating pressure drop designed to adapt to industrial-grade filter equipment load capacity—all precision grades are calibrated to ensure minimal pressure loss while maintaining filtration efficiency. Under the standard nominal flux and 25℃ operating temperature, the initial pressure drop for all precision grades is ≤0.03MPa; the coarse-precision grades (80μm/100μm) have an even lower initial pressure drop (≤0.025MPa) due to the looser filtration layer structure, while the high-precision grades (5μm/10μm) maintain a low initial pressure drop via the expanded effective filtration area, avoiding excessive pressure loss in vertical/horizontal filter units and reducing the energy consumption of industrial water pumps and fluid transfer equipment. The recommended maximum allowable operating pressure drop for all precision grades is 0.2MPa, a heavy-duty design adapted to the high-load operation of vertical and horizontal filters—this higher limit effectively extends the cartridge’s service life and reduces replacement frequency under large-flow, high-impurity conditions. With continuous operation of the filter unit, impurities are gradually accumulated on the filtration layer surface and inside, leading to a slow and stable rise in pressure drop; when the pressure drop reaches 0.2MPa, the cartridge can be cleaned or replaced in a unified manner. The oversized filtration area and graded porous structure delay the pressure drop rise rate, avoiding frequent pressure fluctuations in vertical/horizontal filter housings and ensuring stable system operation. Delayed replacement within a short period will not cause significant impact on the filter unit, fully adapting to the actual maintenance habits of industrial production with scheduled downtime.
Molecular Weight Cutoff (MWCO)
This large PP wound filter cartridge—for all filtration precision grades (5μm-100μm) and applicable to both vertical and horizontal filter housings—adopts a pure physical filtration mechanism based on particle size interception for all filtered media. Its core working principle is to capture insoluble solid particulate impurities in industrial water and fluids according to their actual physical particle size, rather than separating substances based on molecular weight, molecular size or chemical composition—this is fundamentally different from ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membrane components with specific Molecular Weight Cutoff (MWCO) indexes, which are often used in downstream precision water treatment systems of vertical/horizontal filters. Therefore, this product has no specific MWCO index for any precision grade or application scenario. The interception effect is only targeted at solid particulates with a particle size larger than the selected filtration precision; macromolecular organic substances, soluble colloids, dissolved polymers and other dissolved substances in the filtered medium can pass through the cartridge body smoothly as long as their actual particle size is smaller than the filtration precision, and then enter downstream processes or precision filtration systems (if needed) for molecular-level separation and purification. This design fully meets the functional requirements of vertical/horizontal filter housings as primary or secondary filtration units in industrial systems: focusing on the efficient removal of physical particulate impurities in large-flow media, without participating in the molecular-level purification of the fluid, and the abandonment of MWCO-related design further simplifies the cartridge structure, enhances its mechanical strength and adapts it to the heavy-duty operating conditions of industrial vertical/horizontal filters.
Membrane Thickness
The effective PP filtration layer thickness of this large PP wound filter cartridge is heavy-duty optimized and matched with filtration precision and oversized structural design, with a thickness range of 10mm to 30mm—significantly thicker than standard-sized PP wound filter cartridges—designed to withstand the high-pressure, large-flow scouring of vertical and horizontal filter housings and ensure sufficient impurity holding capacity. The thickness is scientifically graded according to filtration precision: the 5μm/10μm high-precision grades feature the thickest filtration layer (20mm-30mm), forming a dense multi-layer graded interception structure with ultra-fine pore size distribution, which ensures the efficient removal of micro-scale impurities and provides an oversized impurity storage space to avoid rapid blockage under large-flow operation; the 20μm/30μm/50μm medium-precision grades (mainstream industrial options) have a moderate heavy-duty thickness (15mm-25mm), balancing filtration density, flux performance and impurity holding capacity, adapting to the general filtration demand of vertical/horizontal filters in most industrial scenarios; the 80μm/100μm coarse-precision grades have a thickened filtration layer (10mm-20mm) with a loose porous structure, optimizing the internal flow channel space for maximum large-flow filtration while ensuring the interception of bulky impurities and anti-scouring performance. The inner support core is reinforced and thickened to 6mm-8mm (honeycomb structure) for all precision grades, with high compressive strength and structural rigidity, able to withstand the operating pressure of up to 1.0MPa in industrial vertical/horizontal filter housings without deformation, rupture or filtration layer displacement. The total outer diameter and length of the cartridge are manufactured in accordance with the universal dimensional specifications of industrial large vertical and horizontal filter housings, ensuring a perfect fit with the housing’s internal structure, no water/fluid short-circuit during installation, and tight sealing with the housing’s end cap—realizing direct and reliable universal replacement.
Replacement Cycle
The replacement cycle of this large PP wound filter cartridge is a heavy-duty design adapted to the high-load operation of vertical and horizontal filter housings, and is comprehensively determined by the selected filtration precision, the impurity content of the filtered medium, and the operating intensity of the filter unit (continuous/intermittent operation), with no fixed short cycle—effectively reducing maintenance frequency and downtime for industrial production. For the 5μm/10μm high-precision grades used in low-impurity, high-purity process water systems (e.g., pharmaceutical, electronic manufacturing) with vertical/horizontal filters operating in intermittent medium load, the replacement cycle is 4-6 months; for the same high-precision grades in continuous high-load operation with slightly higher impurity content, the cycle is 3-4 months. For the 20μm/30μm/50μm medium-precision grades (the most widely used for industrial general filtration) in vertical/horizontal filters for industrial circulating water, cooling water and raw water pretreatment (medium impurity content, continuous large-flow operation), the standard replacement cycle is 5-8 months—this extended cycle is achieved via the oversized effective filtration area and heavy-duty membrane thickness, which significantly improve impurity holding capacity. For the 80μm/100μm coarse-precision grades used in high-impurity, high-turbidity industrial fluid filtration (e.g., metallurgical process water, construction material production water) with vertical/horizontal filters operating in continuous heavy load, the replacement cycle is 6-9 months, as the loose porous structure and large flux reduce impurity accumulation rate and scouring damage. The actual replacement cycle can be appropriately extended by 1-2 months for filtered media with low turbidity and low suspended solid content (SS ≤15 mg/L); for high-impurity media (SS ＞30 mg/L), the cycle is shortened by 1 month. All precision grades support repeated physical backwashing (high-pressure clean water rinsing/compressed air blowing), a design adapted to industrial vertical/horizontal filter housings with built-in backwash systems—backwashing can remove 70%+ of surface and shallow accumulated impurities, extending the replacement cycle by an additional 2-3 months and greatly improving the cartridge’s cost performance. In actual industrial operation, the replacement cycle is also determined by the filter unit’s pressure drop: when the pressure drop reaches the recommended maximum of 0.2MPa or the system flow rate is significantly reduced, the cartridge is replaced in a unified manner during scheduled production downtime, avoiding unplanned shutdowns and ensuring continuous industrial production.
