Water Filter Cartridge

PP Melt-blown Filter Cartridge is a tubular filter element made from non-toxic and odorless polypropylene particles through heating, melting, spinning, drawing and forming. It is not only used in large-scale water purification, but also has excellent chemical compatibility, suitable for filtration of strong acids, strong alkalis and organic solvents. As a deep filtration filter element with fixed pore size made of ultra-fine polypropylene fiber filter material, it meets FDA relevant requirements.

PP Melt-blown Filter Cartridge adopts a gradient pore structure (loose outside and dense inside) to realize physical interception filtration. Raw water flows through the filter element from outside to inside: large-particle impurities such as sediment and rust are intercepted on the outer loose layer, while fine particles and colloids are captured in the inner dense layer. This layered filtration design expands the dirt-holding capacity and prolongs the service life. The filter element can effectively intercept various impurities in water, ensuring stable effluent quality and protecting subsequent precision filtration equipment.

• Gradient pore structure: three-layer filtration (loose layer, compact layer, precision layer) from outside to inside, realizing graded interception and high dirt-holding capacity.

• Multiple types available: flat, threaded and needle-punched PP cotton, suitable for different installation and filtration requirements.

• Internal thread structure: enhances pressure resistance and stability, avoiding deformation under water pressure.

• Polypropylene material: non-toxic, odorless, corrosion-resistant, compatible with various chemical media, meeting FDA food-grade requirements.

• Excellent chemical compatibility: resistant to strong acids, strong alkalis and organic solvents, adaptable to various industrial liquid filtration scenarios.

• Food-grade safety: made of polypropylene material, non-toxic and odorless, meeting FDA requirements, suitable for food and beverage, pharmaceutical industries.

• Flexible selection: multiple types and precision options, meeting different pre-filtration and water purification needs.

• Easy maintenance: simple structure, easy to replace, reducing maintenance workload and cost.

• Electric power industry: pre-filtration of circulating water and boiler make-up water.

• Reverse osmosis pre-treatment: protecting RO membranes, extending their service life.

• Petrochemical and fine chemical industry: filtration of process water and chemical liquids, removing impurities and particulate matter.

• Food and beverage, pharmaceutical industry: production water and product filtration, meeting hygienic and safety standards.
