Water Purifier Activated Carbon Filter Configuration Standard

The water purifier is a small automatic drinking water terminal that uses the reverse osmosis membrane method to carry out secondary deep purification treatment of municipal tap water or potable groundwater as stipulated in the Ministry of Health's 'Hygienic Specifications for Drinking Water Quality' (2001). Handling equipment. There are two types of activated carbon filter products for pure water machines: compressed activated carbon filter cartridges and bulk activated carbon filter cartridges. 1. Compressed activated carbon filter element uses coal-based activated carbon with high adsorption value and coconut shell activated carbon as filter material, and is sintered and compressed with food-grade binder. The inside and outside of the compressed activated carbon filter element is wrapped with a layer of non-woven fabric with filtering function, to ensure that the carbon core itself will not drop carbon powder, and both ends of the carbon core are equipped with soft nitrile rubber gaskets, so that the carbon core can be loaded into the filter cartridge Has good sealing. 2. Bulk activated carbon filter cartridges put the required activated carbon particles into a special plastic shell, and weld the end caps on both ends of the shell with welding equipment. Filter to ensure that the carbon core will not drop carbon powder and black water during use. According to the needs of customers, the shell end cover can be made into different types of connection ports. Interface methods are: flat pressure type, pipeline type (models: 4042, 4044, 4046, etc.). Activated carbon filtration, according to the adsorption characteristics of activated carbon, activated carbon is mainly used for removing pollutants in water, decolorizing, filtering and purifying liquid and gas, and also for air purification and waste gas recovery (such as the recovery of gas benzene in the chemical industry) , Recycling and refining of precious metals (such as the absorption of gold). Activated carbon is mainly made of substances with high carbon content, such as wood, coal, nut shells, bones, petroleum residues, etc. With coconut shell as a common raw material, under the same conditions, the active quality and other characteristics of coconut shell activity are better, because it has a larger specific surface. Activated carbon is a kind of multi-pore carbon compound, which has a very rich pore structure and good adsorption characteristics. Its adsorption is formed by physical and chemical adsorption, and its appearance is black in color. In addition to the main carbon, its composition also contains a small amount of hydrogen, nitrogen and oxygen, and its structure resembles a hexagon. Features, each gram of activated carbon has a specific surface equivalent to 1,000 square meters. The filter element of the water purifier has a service life. The activated carbon filter element is generally 6-12 months, and their service life depends entirely on the local water quality. , water pressure and water consumption.
