Product Introduction
This odorless PP winded filter cartridge is a high-performance food-grade water purification component engineered exclusively for beverage blending water and pure water preparation, tailored to the strict requirements of the beverage industry for odor-free, impurity-free, and high-purity water—core prerequisites for ensuring the original flavor, stability and quality of beverage products. Crafted from 100% odorless food-grade polypropylene (PP) raw materials that comply with FDA, EU 10/2011, national food safety standards and beverage production water quality norms, the cartridge is manufactured through a special deodorization and precision molding process, eliminating any inherent plastic odor or residual volatile substances of the raw material. It adopts advanced multi-layer gradient spiral winding technology with a reinforced porous odorless PP inner core and a dense, uniformly structured odorless PP wire filter layer, dedicated to the efficient physical filtration of raw water for beverage blending and pure water preparation. The cartridge intercepts a full range of insoluble impurities including suspended solids, colloidal substances, rust particles, sediment, fine particulate matter and microbial aggregates, without releasing any odor-causing substances or adding chemical agents during filtration. The pure physical purification process ensures zero secondary pollution, no alteration to the physical and chemical indicators of water, and the purified water achieves odor-free, clear and high-purity characteristics that meet the stringent water quality requirements of beverage production. With perfect compatibility with standard water treatment filter housings, stable odorless filtration performance and adaptability to the large-flow, continuous production characteristics of beverage plants, this cartridge is a core water purification component for beverage manufacturing enterprises, pure water plants and food processing facilities with beverage production lines. It complies with the strict quality and safety control requirements of the beverage industry, lays a solid foundation for the preparation of high-quality beverage blending water and pure water, and ensures the consistency of flavor and quality of finished beverage products such as carbonated drinks, fruit juices, tea drinks and dairy beverages.
Filtration Precision
Calibrated specifically for the impurity characteristics of raw water for beverage blending and pure water preparation (tap water, well water, municipal purified water) and the differentiated filtration needs of beverage blending water pre-purification and pure water pre-filtration, the filtration precision of this odorless PP winded filter cartridge covers a food industry high-purity water standard range of 1 μm to 30 μm, with the most practical and commonly used specifications for beverage production being 1 μm, 5 μm, 10 μm and 20 μm. The 1 μm and 5 μm high-precision specifications are designed for the pre-filtration of pure water preparation systems (reverse osmosis/ultrafiltration) and the purification of high-end beverage blending water (e.g., craft fruit juice, premium tea drinks), effectively intercepting micro colloidal substances, submicron suspended solids, tiny rust particles and microbial aggregates that affect water purity and membrane system safety, ensuring the inlet water quality of advanced water treatment equipment and the high-purity requirement of blending water for premium beverages. The 10 μm and 20 μm medium-precision specifications are applied to the pre-purification of conventional beverage blending water (e.g., carbonated drinks, bottled fruit juice, functional drinks), removing large suspended solids, sediment, coarse particulate matter and pipe scale from raw water, reducing the impurity load of subsequent water treatment links, preventing clogging of beverage production equipment and pipelines, and meeting the basic odor-free and clear water quality requirements of conventional beverage blending. All precision grades adopt odorless food-grade gap-calibrated winding technology with a gradient filter structure, realizing graded interception of impurities of different particle sizes, stable filtration efficiency without precision attenuation, channeling or filter layer deformation during continuous large-flow industrial production. They fully meet the differentiated filtration needs of beverage blending water and pure water preparation, and strictly comply with the national beverage production water quality standards (GB 19298) and pure water quality requirements (GB 17323).
Flux
The flux performance of this odorless PP winded filter cartridge is fully optimized for the physical properties of beverage production water (low viscosity, normal temperature, stable composition), the odorless high-precision filtration demand, and the continuous large-flow water supply characteristics of beverage plants and pure water preparation systems. Under the standard operating conditions of 25℃ (mainstream beverage production water temperature) and 0.2MPa inlet pressure, the initial pure water flux of a single cartridge reaches 12-40 L/min—a high flux level matching its high-precision and odorless design, far exceeding the flux performance of traditional odor-containing PP filter cartridges of the same specification. For actual raw water (tap water/municipal purified water) for beverage blending and pure water preparation, the stable operating flux maintains a high and consistent level for different precision specifications: the 1 μm/5 μm high-precision cartridges have a stable flux of 12-25 L/min per cartridge for pure water pre-filtration and high-end beverage blending water purification; the 10 μm/20 μm medium-precision cartridges have a stable flux of 20-40 L/min per cartridge for conventional beverage blending water pre-purification, unaffected by the normal range of raw water turbidity and trace mineral content. The gradient filter structure and dense odorless PP wire winding process effectively delay flux attenuation during continuous filtration, and the flux remains stable in the middle and late stages of use. Even with the gradual accumulation of insoluble impurities, there is no sudden drop in flux, avoiding the reduction of water supply efficiency of beverage blending water and pure water preparation systems caused by excessive flux attenuation. In addition, the flux design fully considers the parallel use characteristics in large-flow water treatment systems—hundreds of cartridges can be used in parallel in modular filter housing skids without mutual interference, which can flexibly expand the total filtration flow to tens of cubic meters per hour, perfectly meeting the large-flow continuous water supply demand of large-scale beverage production lines and pure water preparation plants.
Salt Rejection Rate
As an odorless food-grade physical filtration component for beverage blending water and pure water preparation based on the pore size interception principle, this PP winded filter cartridge is designed to remove insoluble solid impurities in raw water, and does not have the functional design of desalination, ion removal, or separation of dissolved substances (including trace mineral ions, soluble inorganic salts that meet beverage production standards). Therefore, its salt rejection rate is 0% under all normal beverage production and pure water preparation operating conditions. It only intercepts suspended solids, colloidal substances, rust particles, sediment and other insoluble contaminants in raw water during physical filtration, and will not retain any soluble components in water—including trace calcium and magnesium mineral ions, potassium and sodium ions, and soluble inorganic salts that meet national beverage production water quality standards, nor will it alter the total dissolved solids (TDS) content and pH value of water. This 0% salt rejection rate is a core performance characteristic of the cartridge for beverage production: it ensures that the soluble chemical composition, physical and chemical indicators and mild mineral characteristics of raw water remain completely unchanged after filtration, complying with the differentiated water quality requirements of different beverage products (e.g., mineral-containing blending water for fruit juice, low-TDS water for carbonated drinks), and avoiding the loss of soluble components that may affect the taste, texture and stability of beverage products. At the same time, the 0% salt rejection rate makes the cartridge not affected by the TDS content and ion type of raw water for beverage blending, and can be universally applied to the purification of tap water, well water, municipal purified water and other raw water sources for beverage blending water and pure water preparation.
Pressure Drop
The pressure drop design of this odorless PP winded filter cartridge is fully optimized for the gradient filter structure, the rated working pressure of modular filter housings for beverage water treatment and pure water preparation systems, the low-energy production requirements of the beverage industry, and the normal water supply pressure of beverage production lines (0.15-0.3MPa). It is designed to ensure safe, stable, low-consumption and odorless filtration operation, without bringing additional pressure load to the water delivery pump, filter housing system, advanced water treatment equipment (RO/UF) and beverage production equipment. Under the standard operating condition of 25℃ and initial operation state (no impurity accumulation), the initial pressure drop of a single cartridge is strictly controlled within 0.008-0.03 MPa for 1 μm/5 μm high-precision specifications and 0.005-0.02 MPa for 10 μm/20 μm medium-precision specifications—both far lower than the rated pressure loss of mainstream food-grade filter housings for beverage water treatment and pure water preparation systems. This ultra-low initial pressure drop ensures that the water supply system of beverage plants and pure water preparation lines can operate under normal production pressure without an additional high-pressure booster pump, effectively reducing the energy consumption of the water purification link, and avoiding the damage of pipeline components and advanced water treatment membranes caused by excessive pressure, which is in line with the energy-saving and emission-reduction requirements of modern large-scale beverage production enterprises. With the progress of continuous filtration and the gradual accumulation of insoluble impurities in the gradient filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop for beverage blending water and pure water preparation is 0.20 MPa, which is the critical pressure value for the filter housing system to maintain safe and stable water supply, avoid water leakage and ensure the normal water demand of beverage production lines and pure water preparation equipment. When the pressure drop reaches this value, the cartridge needs to be replaced in a timely manner, which not only ensures the odorless and high-precision filtration effect of beverage blending water and pure water, but also prevents the water supply pressure of the production line from being too low and affecting the continuous large-flow production of beverages and pure water.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision range (1 μm-30 μm), odorless food-grade safety design, gradient filter structure and actual high-purity water demand of beverage blending water and pure water preparation, the molecular weight cutoff (MWCO) of this filter cartridge is set at 10,000 – 400,000 Da, and the MWCO grade is precisely matched with the filtration precision and gradient filter structure to realize targeted interception of macromolecular insoluble impurities in raw water without intercepting small molecular weight water molecules, soluble mineral ions and trace beneficial substances that meet beverage production requirements. The 1 μm ultra-high-precision cartridge with MWCO of 10,000 – 80,000 Da is used for the pre-filtration of pure water preparation RO/UF systems and the purification of premium beverage blending water, effectively intercepting macromolecular colloidal substances, fine organic particle aggregates, submicron suspended solids and microbial aggregates in raw water, ensuring the high purity of inlet water for advanced water treatment equipment and extending the service life of RO/UF membranes. The 5 μm high-precision cartridge with MWCO of 80,000 – 200,000 Da is applied to the purification of high-end craft beverage blending water (e.g., fresh fruit juice, handcrafted tea drinks), removing micro colloidal impurities and fine suspended solids that affect water clarity and beverage flavor, ensuring the odorless and high-purity characteristics of blending water. The 10 μm cartridge with MWCO of 200,000 – 300,000 Da and 20 μm cartridge with MWCO of 300,000 – 400,000 Da are used for the pre-purification of conventional beverage blending water, efficiently removing large molecular weight insoluble contaminants such as bulk suspended solids, sediment, rust particle aggregates and pipe scale in raw water. This graded MWCO design combined with gradient filtration not only ensures the efficient and thorough removal of harmful insoluble impurities in raw water during odorless filtration, but also allows all small molecular weight soluble components (water molecules, mineral ions, trace inorganic salts) to pass through the filter layer smoothly, maximizing the retention of the original water quality characteristics of raw water and meeting the differentiated water quality requirements of different beverage products. At the same time, the 100% odorless food-grade PP raw material and high-precision spiral winding process ensure that the MWCO parameters remain stable without attenuation during the service cycle, even under long-term continuous immersion in water, and no odor-causing substances are released, ensuring the consistent and stable odorless, high-precision filtration effect of beverage blending water and pure water preparation systems.
Membrane Thickness
Aiming at the odorless, high-precision filtration demand of beverage blending water and pure water preparation, the gradient filter structure design, strict food safety and odor-free requirements of the beverage industry, and the continuous large-flow water supply characteristics, the filter layer (wound 100% odorless food-grade PP wire layer) thickness of this odorless PP winded filter cartridge is specially designed as 3-10 mm with graded specifications based on filtration precision, and the total wall thickness of the cartridge (including reinforced porous odorless PP inner core, gradient filter layer and odorless smooth anti-scouring outer protective layer) is 8-17 mm. The dimensional design fully complies with the standard filter cartridge specifications of the beverage and water treatment industry, ensuring perfect installation compatibility with all mainstream 10/20/40-inch modular filter housings (304/316L stainless steel/odorless food-grade PP) for beverage blending water and pure water preparation systems. The ultra-thin filter layer (3-4 mm) is matched with the 1 μm/5 μm high-precision cartridges for pure water pre-filtration and premium beverage blending water purification, adopting an ultra-dense gradient pore structure to ensure the highest filtration precision, excellent water permeability and absolute odorlessness under normal operating conditions, avoiding excessive flow resistance caused by overly thick filter layer and affecting the water supply efficiency of high-purity water systems, while also eliminating any space for odor-causing substance residue. The medium filter layer (5-6 mm) and thickened filter layer (7-10 mm) are applied to the 10 μm/20 μm medium-precision cartridges for conventional beverage blending water pre-purification, with a relatively loose gradient pore structure that provides a larger three-dimensional dirt-holding space, realizes graded interception of different particle size impurities in raw water, delays impurity blockage, extends the service cycle of the cartridge and reduces the replacement frequency under large-flow pre-purification conditions—all while maintaining the odorless characteristic of the cartridge without residual impurities and odor. The reinforced porous odorless PP inner core with optimized thickness (3-4 mm) is made of 100% odorless food-grade PP material, with high compressive strength, uniform water permeability and no odor release, which provides a stable and non-deformable supporting structure for the outer gradient filter layer under the working pressure of the modular filter housing system, avoiding the deformation or collapse of the inner core caused by the hydraulic impact of large-flow water delivery and ensuring the overall structural stability and odorlessness of the cartridge. The odorless smooth anti-scouring outer protective layer (0.4-0.6 mm) is made of modified 100% odorless food-grade PP material, with excellent anti-scouring, anti-corrosion and anti-scale performance, effectively preventing the filter layer from being scoured and damaged by large-flow water flow during continuous production, avoiding the shedding of PP wire particles to ensure the safety and odorlessness of beverage blending water and pure water, and the smooth surface is easy to clean and sanitize before use without residue, complying with the strict hygiene and odor-free control norms of the beverage industry.
Replacement Cycle
The replacement cycle of this odorless PP winded filter cartridge is determined according to the filtration precision specification, the application link (beverage blending water/pure water preparation), raw water turbidity and impurity content, and the continuous water supply load of beverage plants and pure water preparation systems, with strict compliance with the beverage industry’s food safety, odor-free and quality control norms and strong on-site operability for large-scale beverage production enterprises. Under the conventional working condition (25℃, continuous large-flow water supply for 16-24 hours a day, raw water turbidity <5 NTU, matching the rated flow of modular filter housings), the recommended replacement cycle for a single cartridge is strictly differentiated by filtration precision and application link: for the 1 μm/5 μm high-precision cartridges (pure water pre-filtration/premium beverage blending water purification), the replacement cycle is 7-10 days due to the ultra-dense filter structure, continuous interception of micro impurities and the strict odorless requirement—this frequent replacement ensures no impurity residue and odor release, which is the core guarantee for the high purity and odorlessness of pure water and premium beverage blending water; for the 10 μm/20 μm medium-precision cartridges (conventional beverage blending water pre-purification), the replacement cycle is 10-15 days with larger dirt-holding capacity and gradient impurity interception design, effectively reducing the impurity load of subsequent water treatment links while maintaining the odorless characteristic of the cartridge. If the beverage production line and pure water preparation system are in 24-hour continuous full-load production, or the raw water turbidity is higher than 5 NTU (such as rainy seasons, municipal water supply quality fluctuations), the replacement cycle of all specifications of cartridges will be uniformly shortened by 30%—5-7 days for high-precision cartridges and 7-10 days for medium-precision cartridges. Continuous high-flow water supply and high raw water turbidity will accelerate the accumulation of impurities in the filter layer, which may cause impurity residue and potential odor release if not replaced in time; timely replacement can avoid the reduction of filtration effect, the turbidity and odor of beverage blending water and pure water, the clogging of filter housings and advanced water treatment equipment, and the risk of microbial breeding caused by long-term use of the cartridge in water-soaked conditions, which is in strict compliance with the national beverage production water quality standards and food safety control requirements of the beverage industry. In addition, the replacement cycle must be adjusted according to the actual operating parameters of the water purification system: if the pressure drop of the modular filter housing system reaches the recommended maximum value of 0.20 MPa in advance, or the purified water has obvious turbidity, peculiar smell or visible impurities, the cartridge should be replaced immediately regardless of the operating time, to ensure the consistent odorless, high-purity filtration quality of beverage blending water and pure water and the normal continuous production of beverages and pure water.
