High Flow Rate Wire-Wound Filter Cartridge for Centralized Water Supply Systems in Electroplating Workshops
Product Introduction
This high flow rate wire-wound filter cartridge is a specialized water treatment component R&D and manufactured for the centralized water supply systems of electroplating workshops, addressing the core demands of large-flow, continuous and stable water filtration in electroplating production. Adopting industrial-grade high-purity polypropylene (PP) as the core raw material and advanced high-density spiral winding technology, the cartridge is designed with an optimized porous PP inner core and a three-dimensional filter layer structure. It is dedicated to the efficient removal of suspended solids, colloidal impurities, particulate matter and other insoluble contaminants from the raw water, process water and circulating water in the centralized water supply system of electroplating workshops, ensuring the water quality of electroplating production meets the process standards. With excellent high-flow filtration performance, strong dirt-holding capacity and corrosion resistance to electroplating-related water media, this filter cartridge adapts to the 24-hour continuous operation characteristics of electroplating workshop centralized water supply systems, avoids secondary pollution to water bodies during filtration, and provides a stable, reliable and cost-effective filtration solution for the large-scale water supply demand of electroplating production lines. It also effectively reduces the impurity load of subsequent electroplating solution preparation and treatment links, laying a solid foundation for improving electroplating product quality and reducing production defective rates.
Filtration Precision
Calibrated for the water quality requirements of electroplating workshop centralized water supply systems and the characteristics of large-flow filtration, the filtration precision of this high flow rate wire-wound filter cartridge covers a customizable range of 10 μm to 100 μm, with the most commonly used and practical specifications being 20 μm, 50 μm and 80 μm. The 20 μm precision option is suitable for the fine filtration of process water for precision electroplating links (such as electronic component electroplating, jewelry electroplating) in centralized water supply, effectively intercepting fine colloidal impurities and micro suspended solids that may affect electroplating quality; the 50 μm and 80 μm specifications are applied to the coarse filtration of raw water and circulating water in centralized water supply, removing large particulate impurities, sediment and fiber substances in water bodies, reducing the blockage risk of subsequent pipelines, pumps and water treatment equipment. All precision grades maintain stable interception efficiency and uniform filtration gap under high-flow water flow impact, without channeling or precision attenuation, and can meet the differentiated filtration needs of different electroplating processes (copper plating, nickel plating, chrome plating, zinc plating) in the same centralized water supply system.
Flux
As a core performance advantage of this product, the high flow rate filtration performance is fully optimized for electroplating workshop centralized water supply. Under the standard operating conditions of 25℃ ambient temperature and 0.2MPa inlet pressure, the initial pure water flux of this filter cartridge reaches 30-60 L/min per 10 inches of cartridge length, which is far higher than that of conventional wire-wound filter cartridges. For the actual industrial water in electroplating workshops (with a viscosity of 1.0-1.5 mPa·s and normal turbidity <15 NTU), the stable operating flux remains at 25-50 L/min per 10 inches under continuous high-flow operation. This flux performance can be flexibly matched with the large-flow water supply demand of electroplating workshops of different scales, and multiple cartridges can be used in parallel to further expand the total water supply flow without significant flux attenuation. In the middle and late stages of filtration, the flux attenuation rate is controlled within a reasonable range, avoiding the reduction of water supply efficiency of the centralized system caused by excessive flux drop due to impurity accumulation, and ensuring the continuous and stable water supply for electroplating production lines.
Salt Rejection Rate
This high flow rate wire-wound filter cartridge is a physical deep filtration component based on the pore size interception principle, and its core design goal is to remove insoluble solid impurities in water bodies, rather than desalination, ion removal or separation of dissolved substances. Therefore, its salt rejection rate is 0%. It only intercepts suspended solids, colloids, particulates and other insoluble contaminants in the water of electroplating workshop centralized water supply systems, and does not retain the dissolved metal ions, electrolyte components and other soluble substances required for subsequent electroplating solution preparation in water bodies. This characteristic is crucial for electroplating production: it ensures that the chemical composition and ion content of the water used for electroplating solution preparation remain unchanged, complies with the process requirements of electroplating solution configuration, and avoids the impact of unnecessary ion interception on electroplating production processes. At the same time, it also makes the filter cartridge not affected by the salt content of water bodies during operation, and can adapt to the filtration of water with different salt content in electroplating workshops.
Pressure Drop
In order to match the high-flow filtration performance and ensure the low-energy operation of the centralized water supply system, the pressure drop design of this filter cartridge is fully optimized. Under standard working conditions and initial operation state, the pressure drop is strictly controlled within 0.02-0.05 MPa, which means low energy consumption during the initial high-flow operation, and will not bring additional pressure load to the water supply pump, pipeline and other equipment of the electroplating workshop centralized water supply system, reducing the energy consumption cost of the water supply system. With the progress of filtration work and the gradual accumulation of intercepted impurities in the three-dimensional filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop for safe and efficient operation is 0.25 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 high-flow filtration performance, 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 water flow pressure, thus ensuring the safe, stable and economical operation of the entire electroplating workshop centralized water supply filtration system.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision range, high-flow structural design and actual application demands of electroplating workshop centralized water supply filtration, the molecular weight cutoff (MWCO) of this high flow rate wire-wound filter cartridge is set at 300,000 – 1,000,000 Da. This wide MWCO range is precisely matched with the macromolecular colloidal impurities, insoluble macromolecular particulate matter and fiber substances in the industrial water of electroplating workshops, which can effectively intercept all kinds of macromolecular impurities with corresponding molecular weights in the high-flow water body, and prevent these impurities from entering the subsequent electroplating production links to affect product quality. At the same time, this MWCO range allows small molecular weight water molecules, dissolved ions, small molecular organic substances and other soluble components required for electroplating production to pass through the filter layer smoothly at high flow rate, without causing unnecessary interception and resistance, ensuring the unobstructed high-flow water supply of the centralized system and the normal progress of subsequent electroplating solution preparation and production processes. The precise control of MWCO ensures the efficient removal of harmful macromolecular impurities under high-flow conditions, and maximizes the retention of beneficial soluble components in water bodies, realizing the perfect combination of high-flow filtration and precise impurity interception.
Membrane Thickness
Aiming at the high-flow water flow impact and long-term continuous operation characteristics of electroplating workshop centralized water supply systems, the filter layer (wound PP wire layer) thickness of this high flow rate wire-wound filter cartridge is specially designed as 8-15 mm, and the total wall thickness of the cartridge (including the reinforced porous PP inner core, filter layer and outer protective layer) is 15-25 mm. The thickened filter layer design not only provides a larger three-dimensional dirt-holding space to intercept more impurities, extend the service cycle of the cartridge and reduce the replacement frequency under high-flow operation, but also significantly improves the structural strength and impact resistance of the filter layer, making it able to withstand the long-term scouring of high-flow water flow without deformation, displacement or damage. The reinforced porous PP inner core with optimized thickness has higher compressive strength and water permeability, which can provide a stable and reliable supporting structure for the outer thickened filter layer, avoid the blockage or deformation of the inner core under high-flow conditions affecting the overall filtration efficiency and water flow rate. The moderate total wall thickness also ensures that the cartridge is compatible with most standard large-flow industrial filter housings on the market, and multiple cartridges can be installed in parallel in the filter housing to further expand the total water supply flow without affecting the installation density and water flow circulation.
Replacement Cycle
The replacement cycle of this high flow rate wire-wound filter cartridge is optimized according to the actual operating conditions of electroplating workshop centralized water supply systems (24-hour continuous high-flow operation, raw water turbidity, electroplating process requirements). Under conventional working conditions (24-hour continuous operation, raw water turbidity <15 NTU, standard inlet pressure 0.2MPa, flux in the recommended range), the **recommended replacement cycle is 3-6 months**. If the raw water turbidity of the centralized water supply system is relatively high (>15 NTU), or the electroplating workshop is in high-load production with higher water flow demand, the replacement cycle will be shortened to 4-8 weeks. For the precision electroplating process link with higher water quality requirements in the centralized water supply system, it is recommended to shorten the replacement cycle by 15-25% to ensure the stability of filtration effect and water quality. In addition, the replacement cycle needs to be adjusted according to the actual operating parameters of the filtration system: if the pressure drop of the cartridge reaches the recommended maximum value of 0.25 MPa in advance, or the filtration effect is significantly reduced (the turbidity of the filtered water exceeds the electroplating production process standard), the cartridge should be replaced immediately regardless of the operating time. Regular and timely replacement of the filter cartridge can effectively ensure the filtration effect of the centralized water supply system, protect the subsequent water treatment equipment and electroplating production equipment, and avoid the impact of excessive impurity accumulation on electroplating product quality and production efficiency.
