The pure physical pore-size interception process involves no chemical additives, no dissolution of harmful substances, no release of volatile or odor-causing compounds, and no alteration to the intrinsic physical and chemical indicators of water, ensuring zero secondary pollution. With perfect compatibility with standard and customized modular filter housings of food factory central water systems, stable customizable performance and adaptability to the large-flow, continuous and variable operating conditions of food factory water supply, this cartridge is a core customizable filtration component for central water purification systems in all types of food manufacturing facilities. It complies with the strict quality and safety control requirements of the food industry, effectively optimizes the water quality of central supply systems, eliminates impurity contamination risks in food production water, and lays a solid foundation for the hygienic production, product quality stability and shelf life guarantee of all food categories.
Filtration Precision
The filtration precision of this customized PP winded filter cartridge is fully adjustable and tailor-made, with a customizable range of 1μm to 50μm, calibrated and optimized according to the specific water quality requirements of different food production processes, the impurity characteristics of raw water in food factories, and the multi-stage filtration layout of central water purification systems (pre-filtration, fine filtration, precision filtration). For high-purity water demand processes (e.g., beverage blending, dairy product formulation, pure water preparation), the cartridge can be customized to 1μm–5μm high precision, stably intercepting micro colloidal flocs, submicron suspended solids, tiny rust particles and microbial aggregates that affect product purity and process stability. For general food production water processes (e.g., raw material washing, equipment cleaning, cooling water), it can be customized to 10μm–30μm medium precision, efficiently removing large and medium-sized insoluble impurities such as sediment, coarse suspended solids and pipeline scale, balancing filtration efficiency and dirt-holding capacity. For primary pre-filtration links of central water systems with high raw water turbidity, it can be customized to 30μm–50μm coarse precision, intercepting large granular impurities such as sand particles and plant debris to protect subsequent fine filtration components and extend their service life. All customized precision grades are manufactured through a strict gap-calibrated winding process with uniform pore size distribution, no channeling or precision attenuation under normal operating conditions, and strictly comply with the water quality standards of corresponding food production processes, meeting the diversified impurity interception needs of food factory central water purification systems from primary pre-filtration to terminal precision filtration.
Flux
The flux performance of this customized PP winded filter cartridge is custom-designed and scalable, with the initial pure water flux of a single cartridge customizable from 10 L/min to 50 L/min at 25℃ and 0.2MPa inlet pressure, tailored to the large-flow characteristics of food factory central water purification systems and the specific water consumption of different production workshops (high-flow workshops such as beverage production, medium-flow workshops such as meat processing, low-flow workshops such as pastry making). For high-flow central water system main lines and high-water-consumption food production processes (e.g., beverage blending, canned food raw material washing), the cartridge is customized with an optimized large-flux structure (20 L/min–50 L/min per cartridge), featuring an expanded filter layer surface area and a loose gradient pore structure to ensure high water permeability and adapt to the massive continuous water supply demand of food factories. For medium and low-flow branch lines and precision water use processes (e.g., dairy product formulation, fine pastry production), it is customized with a moderate flux structure (10 L/min–20 L/min per cartridge), matching the small and stable water consumption characteristics while maintaining high filtration precision. For actual water quality in food factory central systems (raw water, intermediate water with different turbidity and impurity content), the customized flux structure ensures stable operating flux: the large-flux version maintains a stable flux of 80%–90% of the initial value for low-turbidity water, and 60%–70% for high-turbidity water; the moderate flux version maintains a stable flux of 85%–95% for all normal water quality conditions, unaffected by the normal range of pH, TDS and trace mineral content of food factory water. In addition, the cartridge is designed for parallel use in modular filter housings, and the total filtration flux of the central water system can be flexibly expanded to cubic meters per minute level by combining multiple customized cartridges, perfectly matching the large-flow, multi-branch and process-specific water supply characteristics of food factory central water purification systems.
Salt Rejection Rate
As a customized food-grade physical filtration component for food factory central water purification systems based on the pore-size interception principle, this PP winded filter cartridge is uniformly designed with a 0% salt rejection rate across all customizable precision grades, with the core design objective of retaining all soluble components in water that meet food production standards while removing insoluble impurities. Regardless of the customized filtration precision (1μm–50μm), the cartridge only intercepts suspended solids, sediment, rust particles, colloidal flocs and other insoluble contaminants in water during physical filtration, and does not retain any soluble components in water, including inorganic mineral ions (sodium, potassium, calcium, magnesium) in natural raw water, soluble food-grade additives in formulated production water, and trace soluble organic substances that do not affect food production quality. This 0% salt rejection rate is a non-negotiable core performance characteristic for food factory applications: it strictly ensures that the soluble chemical composition, pH value, TDS content, conductivity and other intrinsic physical and chemical indicators of water remain completely unchanged after filtration, adapting to the diversified soluble water quality requirements of different food production processes (e.g., low-mineral water for beverage production, mineral-containing water for dairy product processing, salt-added formulated water for meat curing). At the same time, the 0% salt rejection rate makes the customized cartridge universally applicable to all water sources of food factory central water systems (tap water, well water, municipal purified water, reclaimed water after preliminary treatment) and all water use links, without causing the loss of beneficial soluble components or altering the water quality characteristics required for specific food production processes.
Pressure Drop
The pressure drop performance of this customized PP winded filter cartridge is precision-tailored according to its customized filtration precision, flux and the operating pressure parameters of food factory central water purification systems (0.15MPa–0.4MPa), ensuring low energy consumption and stable operation of the central water system while meeting filtration demands. For 1μm–5μm high-precision customized cartridges (for fine filtration/precision filtration links), the initial pressure drop at 25℃ and no impurity accumulation is strictly controlled within 0.015MPa–0.03MPa, balancing high filtration precision and low pressure loss to avoid excessive energy consumption in terminal precision water use links. For 10μm–30μm medium-precision customized cartridges (for general production water links), the initial pressure drop is optimized to 0.008MPa–0.02MPa, further reducing energy consumption and matching the large-flow continuous supply characteristics of central water system main lines and branch lines. For 30μm–50μm coarse-precision customized cartridges (for primary pre-filtration links), the initial pressure drop is minimized to 0.005MPa–0.015MPa, ensuring minimal resistance to raw water intake and reducing the load of water delivery pumps in central water systems. The recommended maximum allowable pressure drop is uniformly customized as 0.25MPa for all precision grades, a critical value calibrated to match the pressure-bearing capacity of food factory central water system filter housings, water delivery pipelines and processing equipment. This maximum pressure drop ensures that the cartridge can accumulate a sufficient amount of impurities before replacement, extending the service cycle, while avoiding excessive system pressure that may cause pipeline leakage, equipment damage or flux sharp drop. When the system pressure drop reaches this customized value, timely cartridge replacement ensures the stable operation of the central water purification system and consistent water supply pressure for all food production workshops.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff (MWCO) of this customized PP winded filter cartridge is precision-matched to the customized filtration precision, with a customizable MWCO range of 10,000 Da to 1,000,000 Da, designed to achieve targeted interception of macromolecular insoluble impurities while allowing all small and medium molecular weight soluble components (water molecules, mineral ions, food-grade additives) to pass through unimpeded. For 1μm–5μm high-precision cartridges (for beverage, dairy and other high-purity water processes), the MWCO is customized to 10,000 Da–200,000 Da, effectively intercepting macromolecular colloidal substances, protein-polysaccharide aggregates, micro microbial clusters and fine organic particle aggregates with molecular weights above this range, ensuring the high purity of production water. For 10μm–30μm medium-precision cartridges (for general washing, cooling and cleaning water processes), the MWCO is customized to 200,000 Da–600,000 Da, targeting large molecular weight insoluble impurities such as plant fiber aggregates, rust particle clusters and pipeline scale flocs, balancing impurity interception and water permeability. For 30μm–50μm coarse-precision cartridges (for central water system pre-filtration), the MWCO is customized to 600,000 Da–1,000,000 Da, intercepting ultra-large molecular weight insoluble impurities such as sand particle aggregates, large plant debris and plastic fragments, protecting subsequent filtration components from severe blockage. The high-precision spiral winding process and modular filter layer structure ensure that the customized MWCO parameters remain stable without attenuation throughout the service cycle, even under long-term immersion in food factory water with variable pH, temperature and impurity content, and no adsorption of soluble small and medium molecular weight components occurs. This stable, precision-matched MWCO performance guarantees targeted and efficient impurity interception for each stage of the food factory central water purification system, while fully retaining the soluble water quality characteristics required for food production.
Membrane Thickness
The filter layer thickness and total wall thickness of this customized PP winded filter cartridge are fully modular and tailor-made, with the filter layer (wound food-grade PP wire layer) thickness customizable from 3mm to 12mm, and the total wall thickness (including reinforced PP inner core, filter layer and outer protective layer) customizable from 8mm to 18mm, calibrated to match the customized filtration precision, flux and the installation dimensions of food factory central water system filter housings (standard 10/20/40-inch or customized non-standard housings). For 1μm–5μm high-precision cartridges (fine filtration/precision filtration), the filter layer thickness is customized to 3mm–6mm, featuring a dense, uniform pore structure to ensure high filtration precision, with a total wall thickness of 8mm–11mm for compatibility with small-diameter precision filter housings in terminal water use links. For 10μm–30μm medium-precision cartridges (general production water), the filter layer thickness is customized to 6mm–9mm, adopting a gradient pore structure that balances dirt-holding capacity and water permeability, with a total wall thickness of 11mm–14mm matching the standard modular filter housings of central water system main lines and branch lines. For 30μm–50μm coarse-precision cartridges (primary pre-filtration) and large-flux customized versions, the filter layer thickness is customized to 9mm–12mm, with an expanded three-dimensional dirt-holding space to adapt to high-turbidity raw water and large-flow water supply, and a total wall thickness of 14mm–18mm for enhanced structural stability under high hydraulic impact. The reinforced porous food-grade PP inner core has a customizable thickness of 3mm–5mm, with high compressive strength matching the customized flux and system pressure, avoiding core deformation or collapse under large-flow water delivery. The food-grade smooth anti-scouring outer protective layer has a fixed thickness of 0.5mm–0.8mm (modified PP material), with excellent anti-corrosion, anti-scouring and temperature resistance (0–95℃), adapting to the full temperature range of food factory production water (including high-temperature cleaning water). All customized thickness parameters comply with food industry mechanical and hygiene standards, ensuring perfect installation compatibility with food factory central water system filter housings, while optimizing the cartridge’s filtration performance, structural stability and service life for specific application links.
Replacement Cycle
The replacement cycle of this customized PP winded filter cartridge is flexible and process-specific, determined by its customized parameters (filtration precision, filter layer thickness, flux), the water quality characteristics of food factory central water systems (raw water turbidity, impurity content), the operating mode of the central system (24-hour continuous or intermittent supply) and the specific food production process demands, with a customizable recommended base cycle of 5 days to 30 days, and strong on-site adjustability for food factory operation and maintenance teams. For 1μm–5μm high-precision cartridges (beverage, dairy, high-purity water processes) with a 3mm–6mm filter layer, the base replacement cycle is customized to 5 days–10 days under conventional conditions (25℃, turbidity <5 NTU, 12–16 hours of daily operation), as the dense filter layer accumulates micro impurities rapidly, and frequent replacement ensures high water purity and avoids microbial breeding. For 10μm–30μm medium-precision cartridges (general washing, cooling, cleaning water) with a 6mm–9mm filter layer, the base replacement cycle is customized to 10 days–20 days, balancing impurity interception efficiency and maintenance frequency, adapting to the large-flow and moderate-impurity characteristics of general food production water. For 30μm–50μm coarse-precision cartridges (central system pre-filtration) with a 9mm–12mm thick filter layer, the base replacement cycle is customized to 20 days–30 days, taking advantage of the super large dirt-holding capacity to reduce the frequency of pre-filtration component replacement and lower maintenance costs. The replacement cycle is adjusted according to actual operating conditions: if the food factory central water system operates in 24-hour continuous full-load mode or the raw water turbidity exceeds 10 NTU (e.g., rainy seasons, raw water source fluctuations), all customized cartridges have their replacement cycle shortened by 30%–50%. If the system pressure drop reaches the customized maximum allowable value of 0.25MPa in advance, or the filtered water shows obvious turbidity, visible impurities or abnormal color, the cartridge must be replaced immediately, regardless of the base cycle, to ensure the water quality of the central water system and the normal production of food processes.
