Activated carbon is very commonly used in water purifiers, including granular coconut shell activated carbon (UDF filter element), sintered activated carbon filter (CTO filter element), also known as carbon rod filter element, compressed activated carbon filter element, and post-activated carbon (T33 filter element). In general, activated carbon is made of charcoal, bamboo charcoal, various husks and excellent coal, etc., through physical and chemical methods to crush, sift, catalyst activation, rinsing, drying and screening and a series of processes to process and manufacture, it has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in tap water to achieve the purpose of decolorization, deodorization and removal of chemical pollution and volatile organic compounds.

Granular activated carbon (UDF filter element): The main medium of the activated carbon water purifier is activated carbon particles. Activated carbon is usually placed in a plastic shell, and in order to prevent the leakage of fine particles, other filter materials with higher filtration precision are generally placed at the inlet and outlet of the filter element to intercept it. Compared with other activated carbons, due to the loose distribution of activated carbon particles, the pressure loss of this type of product is relatively small, and the flow rate of pure water is relatively large; It is often used in simple applications such as taste improvement, or as a filter medium that is easily oxidized such as pre-filtration to remove residual chlorine and protect downstream reverse osmosis membranes.

Sintered activated carbon filter element (CTO filter element): The main filter medium of the composite sintered activated carbon rod water purifier is activated carbon rod. Activated carbon rods are usually fired from activated carbon powder and bonding materials of different particle sizes at high temperatures. Due to the porous structure of activated carbon powder (it is estimated that the specific surface area of 3~5 grams of activated carbon powder is equivalent to the size of a standard American football field), the activated carbon rod after firing is very dense, and has a high removal efficiency for pollutants such as odor, odor, residual chlorine and volatile organic compounds in tap water, and the excellent activated carbon rod produced by some manufacturers can even filter sporocysts in accordance with NSF53 standard, without the use of additional filter media such as microfiltration and ultrafiltration. Due to the excellent performance of composite sintered activated carbon rods, this kind of products can be directly used in drinking, cooking and other occasions with high filtration requirements, and can also be used as ultrafiltration, reverse osmosis and other water purifiers to improve the filtration effect.

Post-activated carbon (T33 filter): It is also a kind of granular activated carbon, so I won't explain much here!
