Where Does The Activated Carbon In The Water Filter Cartridge Come From？
Activated carbon as a material with strong adsorption capacity, has been one of the most commonly used media in activated carbon filter cartridge in the water filter. We often hear the word "activated carbon" in our daily life. It is not new to us, but where it comes from and how it is formed? Is the water after filtering of activated carbon filter cartridge safe for human body? Let's explore.
Activated carbon in activated carbon filter cartridge is a kind of specially treated carbon, which heats organic raw materials like shell, coal, wood, etc under the condition of air isolation to reduce non carbon components, which process is called carbonization, and then reacts with gas, the surface is eroded, resulting in the structure with developed micropores, which process is called activation. Because the activation process is a micro process, that is, a large number of molecular carbide surface erosion is point erosion, so the surface of activated carbon has numerous tiny pores. The micropore diameter on the surface of activated carbon is mostly between 2-50nm. Even a small amount of activated carbon has a huge surface area. The surface area of every gram of activated carbon is 500-1500㎡. Almost all the applications of activated carbon are based on this feature of activated carbon. Same thing is true for activated carbon filter cartridge.
Coconut shell activated carbon is made from high-quality coconut shells from Hainan, Southeast Asia and other places. The raw materials are screened, steam carbonized, refined, and then processed by a series of processes such as impurity removal, activation and screening. Coconut shell activated carbon is black granular, with developed pore structure, high adsorption capacity, high strength, chemical stability and durability; Shell activated carbon is mainly made of shell and sawdust, which are carbonized, activated and refined. It is characterized by large specific surface area, high strength, uniform particle size, developed pore structure and strong adsorption performance. It is suitable for pharmaceutical, petrochemical, sugar, beverage, alcohol purification industries, decolorization, purification, purification and sewage treatment of organic solvent; Wood charcoal is made of high-quality wood and powder shape. It is refined through high-temperature carbonization, activation and various processes. It has the characteristics of large specific surface area, high activity, developed micropores, strong decolorizing power, large pore structure, and can effectively absorb various substances and impurities such as color in liquid.
In about 3750 BC, ancient Egypt had recorded the use of charcoal. So far, it has been widely used in people's daily life. Activated carbon has passed the test of time, also used in our activated carbon filter cartridge.
Our activated carbon block filter cartridge is made of high-quality activated carbon or NSF certified activated carbon and harmless adhesive as raw materials by extrusion molding or sintering. The filter element has the advantages of low ash content, wide and even micropore distribution, excellent adsorption of residual chlorine, odor, pigment and removal of organic compounds. Among them, coconut shell activated carbon filter has a better removal effect on trihalomethane and other chemicals.
Our sintered activated carbon block filter is made of high-quality activated carbon with mesh of 80-300 and sintered with hydrophilic polymer. Keep the excellent performance of activated carbon, and have good filtration performance at the same time. The removal of residual chlorine and decolorization can reach more than 98%. It can be compared with German and American products.
Our granular activated carbon filter cartridge uses high-quality activated carbon certified by NSF as raw material to effectively absorb residual chlorine, odor and pigment, and remove organic matters, residual pesticides and other chemicals in water. After acid pickling and air separation, the ash content of all activated carbon is greatly reduced. The two ends of the filter cartridge are lined with special melt blown mats instead of ordinary non-woven fabrics, so that the filter cartridge has good efficiency, high flow rate, and no black water is discharged.
