1, Core technology of precision filter bottle: 5-micron PP cotton filter medium
As an important equipment in modern water treatment technology, the core of precision filter bottles lies in the selection and design of filter media. 5-micron PP cotton (polypropylene fiber cotton) is an ideal material for filtering particulate matter, floating particles, and fine particles in water due to its unique physical and chemical properties.
The physical structure of PP cotton
PP cotton is made by melt spraying process, with fine fiber diameter and three-dimensional network distribution, forming a multi-layer gradient filtration structure. A 5-micron aperture design can effectively intercept impurities with a diameter greater than 5 microns (such as sediment, rust, colloids, etc.), while allowing water molecules and small mineral particles to pass through, balancing filtration accuracy and water flow rate.
Chemical stability and safety
Polypropylene, as a food grade material, is acid and alkali resistant, non-toxic, and will not release harmful substances after long-term use. Its hydrophobic characteristics can also inhibit bacterial growth and avoid secondary pollution.
Multi layer composite filtration mechanism
Precision filter bottles usually adopt a multi-layer PP cotton structure with "outer sparse and inner dense": the outer fibers are loose, intercepting large particles; The inner fibers are tightly packed, adsorbing fine suspended solids. This design significantly extends the lifespan of the filter element and reduces the risk of clogging.
Selected for its food-grade quality, PP cotton serves as a highly efficient barrier against sand, colloidal matter, and suspended solids in water. It safeguards subsequent filters and integrates seamlessly into sophisticated water treatment setups, including precision filtration guardians and RO reverse osmosis systems for purified water.
Premium food-grade PP cotton effectively filters out large particles such as sediment, colloids, and suspended solids from water, safeguarding subsequent filter elements and is ideally suited for sophisticated water treatment systems including precision filtration units and RO reverse osmosis water purifiers.
- PP cotton offers excellent filtration performance, softness, durability, lightweight properties, and cost-effectiveness. These advantages make it a versatile material with a wide range of applications in different industries.
