Long-life PP Wound Filter Cartridge: Matching Filter Cartridge for Industrial Filtration Stations and Water Purification Units
Product Introduction
This long-life PP wound filter cartridge is a professional filtration component engineered for the high-demand operating conditions of industrial filtration stations and water purification units, adopting high-purity polypropylene (PP) fiber as the core raw material and advanced multi-layer winding craft. Its optimized winding density and structural design not only enhance the impurity-holding capacity of the cartridge but also extend the continuous service life significantly, making it an ideal matching filter cartridge for large-scale, continuous, and high-efficiency water treatment systems in industrial scenarios. The all-PP material composition ensures excellent chemical stability, non-toxicity and odorlessness, with no secondary pollution to the filtered water, and it can adapt to the complex water quality characteristics of industrial raw water and process water, maintaining stable filtration performance under long-term continuous operation.
Filtration Precision
The long-life PP wound filter cartridge provides a full range of filtration precision options to meet the differentiated purification needs of industrial filtration stations and water purification units, with standard precision grades covering from 1 μm to 200 μm. The graded winding design of the filter layer realizes the gradient interception of impurities, with the outer layer intercepting large-particle impurities and the inner layer capturing fine particulate matter, which not only improves the overall filtration efficiency but also avoids rapid blockage of the cartridge caused by concentrated interception of impurities. The uniform pore size distribution of the PP fiber ensures consistent filtration effect of the whole cartridge, effectively removing suspended solids, sediment, colloids, rust particles and other insoluble impurities in industrial water.
Flux
Benefiting from the scientific multi-layer winding structure and large effective filtration area, this filter cartridge exhibits excellent flux performance under industrial operating conditions. At the standard working condition of 25℃ and 0.25MPa inlet pressure, the initial pure water flux reaches 100-180 L/m²·h, and the actual working flux for industrial raw water treatment remains stable at 60-120 L/m²·h for a long time. Even in the later stage of use, with the gradual interception of impurities, the flux attenuation rate is significantly lower than that of ordinary PP wound filter cartridges, which can meet the large-flow continuous filtration demands of industrial filtration stations and water purification units without frequent replacement affecting the system operation efficiency.
Salt Rejection Rate
As a precision microfiltration filter cartridge for solid-liquid separation, this long-life PP wound product is not designed with ion separation and rejection functions, which is different from reverse osmosis and nanofiltration membrane components. Its salt rejection rate is 0%, which means it only intercepts insoluble particulate impurities in the water while allowing all soluble salt ions, mineral substances and small molecular weight soluble substances to pass through smoothly. This characteristic makes it suitable for industrial water treatment scenarios that require impurity removal without changing the original ionic composition of water, such as the pre-filtration of process water in chemical, electronic and food industries.
Pressure Drop
The product is designed with a low-pressure drop optimization, and the initial pressure drop is only 0.01-0.04 MPa under the rated working flux and standard temperature conditions, which minimizes the water flow resistance of industrial filtration stations and water purification units, and reduces the energy consumption of the water pump in the system. During the long-term use process, due to the high impurity-holding capacity and gradient interception design, the pressure drop of the cartridge rises in a slow and linear manner; the maximum allowable operating pressure drop is 0.18 MPa, and beyond this value, the cartridge is recommended to be replaced in time to ensure the normal operation pressure and filtration efficiency of the entire industrial water treatment system.
Molecular Weight Cutoff (MWCO)
This long-life PP wound filter cartridge has a molecular weight cutoff range of 150,000 to 600,000 Daltons, which can effectively intercept macromolecular substances in industrial water such as colloidal particles, large molecular weight organic matter, microbial flocs and polymer impurities. The precise control of MWCO ensures that water molecules and small molecular weight beneficial substances (such as inorganic salts required for partial industrial processes) pass through the filter layer smoothly, realizing the optimal balance between efficient impurity removal and the retention of effective components in water, and meeting the process requirements of different industrial water purification links.
Membrane Thickness
The PP fiber filter layer of the cartridge adopts a multi-layer composite design with a total effective membrane thickness of 150-250 μm, and the inner and outer protective layers and support skeleton are reinforced with high-strength PP mesh with a thickness of 80-100 μm each. The thickened and graded filter membrane design not only greatly improves the impurity-holding capacity of the cartridge and lays a solid foundation for its long service life, but also enhances the mechanical strength of the filter layer. The reinforced support structure can resist the impact of high water flow and pressure fluctuations in industrial systems, preventing the filter layer from being damaged or deformed during long-term continuous operation.
Replacement Cycle
Under the normal operating conditions of industrial filtration stations and water purification units (raw water turbidity ≤10 NTU, 24-hour continuous operation, regular routine maintenance), the recommended replacement cycle of this long-life PP wound filter cartridge is 6-12 months, which is 2-3 times longer than that of ordinary PP wound filter cartridges. If the raw water quality is poor (turbidity >10 NTU) or the system operates at an ultra-high flux for a long time, the replacement cycle can be appropriately shortened to 3-6 months. In addition, when the system pressure drop reaches the maximum allowable value of 0.18 MPa or the water flow rate decreases significantly and cannot be restored after simple backwashing, the filter cartridge should be replaced immediately to avoid affecting the overall operation of the industrial water treatment system.
