Activated carbon filter cartridges are made from high-quality fruit shell carbon and coal-based activated carbon as raw materials, with food-grade adhesives, using high-tech technology and special processing techniques. They combine adsorption, filtration, interception, and catalysis, effectively removing organic matter, residual chlorine, and other radioactive substances from water, and have the functions of decolorization and odor removal. There are many types of activated carbon filter cartridges, each playing a different role in different industries. Below, we will learn about the properties of six common types of activated carbon filter cartridges. 1.

　　Activated carbon filters are made from high-quality fruit shell carbon and coal-based activated carbon as raw materials, with food-grade adhesives, using high-tech technology and special processing techniques. They combine adsorption, filtration, interception, and catalysis, effectively removing organic matter, residual chlorine, and other radioactive substances from water, and have the functions of decolorization and odor removal. There are many types of activated carbon filters, each playing a different role in different industries. Below, we will learn about the properties of six common types of activated carbon filters.

　　1. Granular Activated Carbon Filter UDF

　　Granular activated carbon filters use fruit shell activated carbon or coal-based activated carbon as materials; some also use coconut shell. In water treatment, they are used to adsorb organic matter, chemical pesticides, residual chlorine, discoloration, and odors in water. The service life is 3-6 months.

　　Activated carbon granular filters are filled in plastic filter shell containers without any chemical additives. Multiple layers of ultra-fine fiber non-woven fabric are used at the top and bottom inlet and outlet to prevent the release of carbon powder. The outer shell is made of SBS material using ultrasonic welding technology. Because the liquid flows from bottom to top, the contact time and area between the liquid and the activated carbon particle layer are long and wide.

　　2. Compressed Activated Carbon Filter CTO

　　Coal-based activated carbon with an iodine value of over 900 is used as the filter material, and it is sintered and compressed with food-grade adhesives.

　　CTOs are used in water treatment equipment to remove residual chlorine, chemical pesticides, discoloration, odors, and filter fine impurities. In pure water machines, they are used in the third stage to protect the RO membrane. The service life is 3-6 months.

　　CTO is named after its shape; its processing has several molding methods: sintering, compression, and extrusion.

　　3. Fiber Activated Carbon Filter

　　This type uses activated carbon felt, used for filtering PCB chemical solutions, surface treatment, electroplating solution filtration, photographic developer filtration, and removal of oils and aromatics from solutions. It is a filter material structure that combines the dual functions of odor, malodor, and organic pigment removal with activated carbon adsorption. The outer layer of the filter's central column is covered with a precise fiber filter material, and then surrounded by activated carbon fiber cloth. When liquid flows through the filter material, the outer layer's deep fiber filter material structure can block polluting particles.

　　For low-viscosity, low-impurity filtration, textile fibers and activated carbon fibers are precisely wound onto a porous skeleton (polypropylene or stainless steel) using a specific process.

　　It has an outer-loose, inner-dense honeycomb structure that effectively removes suspended solids, particles, rust, organic solvents, and other impurities from liquids, exhibiting excellent filtration characteristics.

　　The filter medium is composed of high-quality activated carbon fibers; activated carbon-impregnated fibers are also used, and sometimes fiber paper.

　　◎The filter is a deep filter with high flow rate; it is heat-resistant and acid-base resistant;

　　◎It has a strong adsorption capacity for chlorine gas, organic matter, and odors; no harmful substances are released.

　　4. Using high-quality coconut shell activated carbon as the filter material, mainly used to improve the taste of water and eliminate odors.

　　Generally, sintered filters are used. Some products use silver-treated high-quality activated carbon filter materials, utilizing the bactericidal principle of silver atoms to sterilize the pure water pipeline of the water purifier, ensuring water quality safety and hygiene. The service life of the post-activated carbon is generally 4-6 months.

　　It performs deep processing of pure water produced by reverse osmosis, removing volatile organic compounds and odors from the water and improving the taste. Especially for pure water machines using pressure water tanks, post-activated carbon can effectively remove odors generated by the water tank.

　　5. Composite Activated Carbon Filter

　　Some activated carbon filters add a certain amount of PP melt-blown cotton during the design process, so that it not only has the function of activated carbon but also the function of deep filtration. This filter is called an activated carbon/PP composite filter, or activated carbon filter for short. It can retain common sand, rust, and small particles, and can also effectively remove residual chlorine, pigments, and odors.

　　6. Other Activated Carbon Filters

　　KDF is a high-purity copper and zinc granule that performs water treatment through electrochemical oxidation-reduction (electron transfer). It can remove up to 99% of chlorine and heavy metals such as lead, mercury, nickel, chromium, and other soluble metals from water. It is highly effective in controlling bacterial colonies, fouling, and algae growth.
