Product Introduction
This industrial grade PP wire-wound filter cartridge is a professionally engineered water treatment component tailored for the water pretreatment process in electronic component production, a field with stringent requirements for water quality purity. Crafted from high-quality, industrial-grade polypropylene (PP) raw materials and manufactured via advanced precision spiral winding technology, the cartridge features a porous PP inner core and a uniformly wound PP wire filter layer. It is designed to efficiently remove suspended solids, particulate impurities, colloids and other insoluble contaminants from raw water, process water and cooling water in electronic component production lines, laying a solid foundation for subsequent advanced water treatment processes such as reverse osmosis, ultrafiltration and ion exchange. With excellent chemical stability, high dirt-holding capacity and adaptable structural design, this filter cartridge meets the industrial-scale continuous operation demands of electronic manufacturing plants, and ensures no secondary pollution to water bodies during filtration, complying with the strict water quality pretreatment standards for electronic component production.
Filtration Precision
Calibrated specifically for the water pretreatment needs of electronic component production, the filtration precision of this industrial grade PP wire-wound filter cartridge covers a customizable range of 5 μm to 100 μm, with the most commonly used specifications being 10 μm, 20 μm and 50 μm. The 10 μm and 20 μm precision options are ideal for fine pretreatment of water used in the production of high-precision electronic components such as microchips, printed circuit boards (PCBs) and semiconductor devices, effectively intercepting micro suspended solids and fine colloidal particles that may affect subsequent advanced filtration and component manufacturing quality. The 50 μm and 100 μm specifications are suitable for coarse pretreatment of raw water and cooling water, removing large particulate impurities to reduce the load of subsequent water treatment systems and protect core precision filtration equipment. All precision grades maintain consistent interception efficiency and stable filtration performance under industrial continuous operation conditions.
Flux
Under the standard operating conditions of 25℃ ambient temperature and 0.2MPa inlet pressure, the initial pure water flux of this industrial grade PP wire-wound filter cartridge is 15-35 L/min per 10 inches of cartridge length. For actual industrial water in electronic component production (with a viscosity of 1.0-1.2 mPa·s and low turbidity), the stable operating flux is 10-28 L/min per 10 inches, which is perfectly matched with the medium-to-large flow water pretreatment demand of industrial production lines in electronic manufacturing plants. The flux attenuation rate is low in the normal service cycle; even with the gradual accumulation of impurities, the flux remains stable within a reasonable range, avoiding the reduction of water supply efficiency caused by excessive flux drop and ensuring the continuous and stable operation of electronic component production water systems. The flux performance can be further optimized by adjusting the number of parallel filter cartridges according to the actual water consumption of the production line.
Salt Rejection Rate
As a physical deep filtration component relying on the principle of pore size interception, this industrial grade PP wire-wound filter cartridge is not designed for desalination, ion removal or dissolved solid separation, and its salt rejection rate is 0%. It only targets and intercepts insoluble solid impurities such as suspended solids, particulates and colloids in the pretreatment water for electronic component production, and will not retain beneficial dissolved ions or affect the ion balance of the water body within the normal process range. This characteristic is crucial for the subsequent water treatment processes in electronic component production, as it ensures that the advanced treatment systems such as reverse osmosis can focus on desalination and high-purity purification without being interfered by the interception of dissolved substances, and also meets the water quality requirements of different electronic component production processes for dissolved ion components.
Pressure Drop
The initial pressure drop of this filter cartridge under standard working conditions is strictly controlled within 0.01-0.04 MPa, which means low energy consumption in the initial stage of operation and no additional pressure load on the water supply pump and pipeline system of the electronic component production line. With the progress of filtration work and the gradual accumulation of intercepted impurities in the filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop is 0.20 MPa; when the pressure drop reaches this value, the filter cartridge needs to be cleaned or replaced in a timely manner. This pressure drop setting balances the dirt-holding capacity and operating energy consumption of the cartridge, avoiding excessive energy consumption caused by overly high pressure drop, and also preventing the damage of the filter layer structure due to ultra-high pressure, thus ensuring the safe and economical operation of the entire water pretreatment system.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision range, structural characteristics and actual application demands of water pretreatment for electronic component production, the molecular weight cutoff (MWCO) of this industrial grade PP wire-wound filter cartridge is set at 200,000 – 800,000 Da. This MWCO range is precisely matched with the colloidal impurities and macromolecular particulate matter in the industrial water for electronic manufacturing, which can effectively intercept colloidal particles and macromolecular insoluble substances with corresponding molecular weights in the water body. At the same time, it allows small molecular weight water molecules, dissolved ions and small molecular organic substances (within the process allowable range) to pass through smoothly. This precise MWCO control ensures the efficient removal of harmful macromolecular impurities in the pretreatment stage, and avoids the unnecessary interception of small molecular substances, which is conducive to the smooth progress of subsequent advanced water treatment and the improvement of the overall treatment efficiency of the water system.
Membrane Thickness
The filter layer (wound PP wire layer) thickness of this industrial grade PP wire-wound filter cartridge is 5-12 mm, and the total wall thickness of the cartridge (including the porous PP inner core and the outer protective layer) is 12-20 mm. The thickened filter layer design is specially optimized for the industrial continuous operation characteristics of electronic component production, which not only provides a larger dirt-holding space to intercept more impurities and extend the service cycle of the cartridge, but also ensures the structural strength of the filter layer, making it resistant to the impact of water flow in large-flow industrial water supply systems and not easy to deform or damage. The porous PP inner core with reasonable thickness ensures sufficient water permeability while providing a stable supporting structure for the outer filter layer, avoiding the blockage of the inner core affecting the overall filtration efficiency. The moderate total wall thickness also ensures the cartridge is compatible with most standard industrial filter housings, without affecting the installation density and flow rate of parallel cartridges.
Replacement Cycle
The recommended replacement cycle of this industrial grade PP wire-wound filter cartridge is 2-4 months under the conventional working conditions of electronic component production water pretreatment (24-hour continuous operation, raw water turbidity <10 NTU, standard operating pressure and flux). If the raw water turbidity is relatively high (>10 NTU) or the production line has a higher water flow demand and the cartridge is under high-load operation, the replacement cycle will be shortened to 3-6 weeks. In addition, the replacement cycle needs to be adjusted according to the actual operating parameters of the water treatment system: if the pressure drop of the cartridge reaches the recommended maximum value of 0.20 MPa in advance, or the filtration effect is significantly reduced (the turbidity of the filtered water exceeds the pretreatment process standard), the cartridge should be replaced immediately regardless of the operating time. For the fine pretreatment link of high-precision electronic component production (such as PCB electroplating water, semiconductor production water), it is recommended to shorten the replacement cycle by 10-20% to ensure the stability of water quality and avoid the impact of excessive impurity accumulation on subsequent advanced treatment processes. Regular maintenance and replacement can effectively protect the subsequent high-value water treatment equipment and ensure the consistent quality of the pretreatment water.
