This 10-inch PP wound filter cartridge is a high-performance pre-filtration component crafted from pure polypropylene (PP) raw materials through a precise winding process. It is engineered as a dedicated pre-filter for sediment removal, featuring a uniform and dense winding structure that forms a three-dimensional filtration matrix. This design enables effective interception of solid particulate impurities while maintaining excellent hydraulic conductivity, making it an ideal pre-filtration solution for tap water, groundwater, and well water treatment systems. It is compatible with most standard 10-inch filter housings, easy to install and assemble, and free of any toxic or harmful additives, ensuring safe and eco-friendly water treatment without secondary pollution to the water source.

The filtration precision of this 10-inch PP wound filter cartridge is available in multiple common specifications ranging from 1 μm to 100 μm, including 5 μm, 10 μm, 20 μm, 50 μm, which can be customized according to actual water treatment needs. The graded winding design of the cartridge ensures that different precision levels can accurately intercept sediment particles of corresponding sizes, from fine silt and clay particles to larger sand grains and rust residues, meeting the diversified pre-filtration precision requirements of different water quality conditions.

Under the standard operating condition of 25℃ and 0.2MPa inlet pressure, the nominal flux of this 10-inch PP wound filter cartridge is 8-15 L/min (liters per minute) for the whole cartridge. The flux value is slightly adjusted according to different filtration precision specifications: the lower the filtration precision (smaller micron number), the slightly lower the flux, and the higher the filtration precision (larger micron number), the higher the flux. The rational winding density ensures the balance between filtration efficiency and flux, avoiding excessive flux loss while ensuring impurity interception.

As a sediment pre-filter cartridge, this PP wound filter cartridge is designed for the physical interception of solid particulate impurities and does not have an ion rejection function. Therefore, it has no salt rejection rate, and the dissolved inorganic salts, ions and other soluble substances in the water can pass through the cartridge smoothly without being retained, which is consistent with the functional positioning of pre-filtration and will not change the original mineral composition of the water body.

The initial pressure drop of the new 10-inch PP wound filter cartridge under the standard nominal flux is ≤0.03MPa at 25℃. With the continuous progress of filtration work, as the impurities are intercepted and accumulated on the surface and inside of the cartridge, the pressure drop will gradually increase. When the pressure drop reaches 0.1MPa (the recommended maximum operating pressure drop), the cartridge needs to be cleaned or replaced in time to ensure the normal operation of the water treatment system and avoid the decrease of water output caused by excessive pressure drop.

This PP wound filter cartridge adopts physical filtration based on particle size interception, and its filtration principle is not based on the molecular weight of substances, so it has no specific Molecular Weight Cutoff (MWCO) index. Its interception effect is only aimed at solid particulate impurities with specific particle sizes, and macromolecular organic substances in water can pass through the cartridge as long as their particle size is smaller than the filtration precision of the cartridge, which is different from ultrafiltration and nanofiltration membranes with MWCO characteristics.

The effective filtration layer thickness of the 10-inch PP wound filter cartridge is 5-8mm, and the total thickness of the whole cartridge (including the inner support core and the outer filtration layer) is matched with the standard 10-inch filter housing design, with the outer diameter of the cartridge being the common 63mm/70mm specifications in the industry. The moderate thickness of the filtration layer ensures sufficient impurity holding capacity, avoids the rapid blockage of the cartridge, and at the same time ensures the flexibility of the cartridge and the close combination with the filter housing to prevent water short-circuit.

The recommended replacement cycle of this 10-inch PP wound filter cartridge is 1-3 months under the standard domestic water treatment condition (daily water output of 200-500L). The actual replacement cycle is affected by the raw water quality: for raw water with high sediment content (such as well water and groundwater with serious sand mixing), the replacement cycle is shortened to 1 month; for tap water with relatively clean water quality, the replacement cycle can be extended to 3 months, and it can also be determined according to the pressure drop change of the system—when the pressure drop reaches 0.1MPa, it needs to be replaced immediately regardless of the use time.

This 10-inch PP wound filter cartridge has a number of outstanding performance features: first, it is made of food-grade PP raw materials, which is acid and alkali resistant, corrosion resistant, and can adapt to the pH value range of 1-13 of the water body, with good chemical stability; second, the integral winding forming process has no bonding agent, avoiding the dissolution of harmful substances and ensuring the safety of filtered water; third, it has a large impurity holding capacity, and the three-dimensional filtration structure can store a large amount of sediment impurities, reducing the frequency of replacement; fourth, it has a wide range of precision specifications, which can be customized according to water quality needs, with strong adaptability; fifth, it is compatible with standard 10-inch filter housings, with simple installation and disassembly, no need for professional tools, and convenient daily maintenance; sixth, the inner support core is made of rigid PP, with good pressure resistance, and it is not easy to deform and rupture under the operating pressure of 0.4MPa, ensuring the structural stability of the cartridge.

This PP wound filter cartridge is mainly used as a pre-filter for sediment removal in the field of water treatment, and its core application fields include domestic water treatment: it is installed in household water purifiers, front-mounted water filters, to remove sediment, rust and sand in tap water, groundwater and well water, protecting the subsequent precision filter elements (such as activated carbon, RO membrane); rural water supply treatment: used in rural household and collective well water, groundwater purification systems, solving the problem of high sediment content in natural water sources; commercial small water treatment: applied in small catering shops, barber shops, small beauty salons and other small commercial places for pre-filtration of tap water, ensuring the cleanliness of water for daily use; industrial water pre-filtration: used as the pre-filtration link of industrial cooling water, process water and cleaning water in small and medium-sized enterprises, intercepting large particulate impurities and protecting industrial water treatment equipment; municipal water supply secondary filtration: used in the secondary water supply system of residential quarters, to remove the sediment and rust generated in the water pipe transportation process, improving the quality of terminal tap water.

In summary, this 10-inch PP wound filter cartridge is a cost-effective and high-reliability sediment pre-filter cartridge, which is specially designed for the sediment removal demand of tap water, groundwater and well water. Its scientific structural design, food-grade raw material selection and diversified performance specifications make it an indispensable core component in the pre-filtration link of water treatment systems. It can effectively intercept solid particulate impurities, protect the subsequent precision water treatment equipment, extend the service life of the whole water treatment system, and at the same time ensure the safety and cleanliness of the initial filtered water. With the advantages of easy installation, convenient maintenance and low use cost, it is widely applicable to domestic, rural, small commercial and small industrial water treatment scenarios, and can provide stable and efficient pre-filtration protection for various water treatment systems with different water quality conditions and use demands. It is a practical and reliable choice for sediment pre-filtration of natural water sources such as groundwater and well water.
