The PP melt-blown filter cartridge is a tubular filter made of non-toxic and tasteless polypropylene particles through heating, melting, spraying, drawing and forming. It is not only used for large-scale water purification, but also has excellent chemical compatibility, suitable for filtration of strong acids, strong alkalis and organic solvents. This filter cartridge is a fixed pore depth filter with ultra-fine polypropylene fiber as the filter medium, and the filter material meets FDA relevant requirements.

Working PrincipleIt mainly uses activated carbon organic coagulum with high carbon content, large molecular weight and large specific surface area to physically adsorb impurities in water to meet water quality requirements. When water flows through the pores of activated carbon, various suspended particles, organics, etc. are adsorbed in the pores of activated carbon under the action of van der Waals force; at the same time, chlorine (hypochlorous acid) adsorbed on the surface of activated carbon undergoes chemical reaction on the surface of activated carbon, and is reduced to chloride ions, thus effectively removing chlorine, ensuring that the residual chlorine in the effluent is less than 0.1ppm, meeting the operating conditions of RO membrane. As the retained substances in the pores of activated carbon and particles increase over time, the pressure difference before and after the filter cartridge rises until it fails.
AdvantagesStepped progressive filtration with loose outside and dense inside, layered filtration, good interception effect and long service life. Adopt internal thread structure to enhance compressive strength. Made of PP polypropylene material. Increase filtration area.
