Can the water filtered by the activated carbon filter be drunk? Activated carbon belongs to crystalline carbon, which is mainly based on physical adsorption in the process of water treatment. Because it has a huge adsorption surface area, its adsorption force is very strong. Generally, the specific surface area of activated carbon is above 1000m2/g, and the total volume of fine holes can reach 0.6-0.18 ml/g, statistical distribution of aperture 1-104.The adsorption capacity of activated carbon has obvious removal effect on halides and total trihalogen methane in water, but the removal effect of microorganisms (bacteria, viruses) and dissolved heavy metal ions in water is not obvious. If the water filtered by activated carbon can be drunk directly, this mainly depends on the water quality of the filtered raw water.If the bacteria and heavy metals in the water exceed the standard, then the filtered water cannot be drunk directly. At present, there are few water purifiers made of only activated carbon as a fil
