Main purification functions:
Remove residual chlorine and odor
Activated carbon quickly neutralizes residual chlorine in tap water through chemical adsorption, eliminating the "bleaching smell". It also absorbs odors and odors caused by phenol, humic acid, etc., improving the taste of drinking water.
Adsorption of organic pollutants
It has the ability to efficiently remove pesticide residues, dyes, trihalomethanes (THMs) and other disinfection by-products, and is especially suitable for organic matter with a molecular weight of 500-1000 to reduce potential carcinogenic risks.
Partial removal of heavy metals
Coconut shell-based activated carbon has a good adsorption effect on lead, arsenic, cyanide, etc. However, attention should be paid to the risk of possible precipitation after long-term use. It is recommended to replace the filter element regularly.
Decolorization and improvement of purity
It absorbs colored impurities in water and improves transparency. It is often used in high-end water purification equipment to improve water purity.
Application forms and selection suggestions:
Household water purifier: Mostly use granular coconut shell activated carbon, which has high mechanical strength, is not easy to remove powder, and is suitable for long-term filtration.
Municipal water plants: often use the "Ozone-Biological Activated Carbon" process, combined with microbial degradation, to extend the life of the filter material and improve purification efficiency.
Type not recommended: Bamboo charcoal is not suitable for long-term use in drinking water purification because it may release heavy metals, change pH value, and easily breed bacteria.
