Abstract

Active carbon that has high total trihalomethane filtration capacity even in water pass-through treatment with a high superficial velocity (SV) is provided. Of the pore volume calculated by the QSDFT method, the pore volume A in this active carbon of pores with a diameter of less than or equal to 1.5 nm is 0.3-0.5 cc/g, and, of the pore volume calculated by the QSDFT method, the pore volume B of pores with a diameter in the range 1.5-2.5 nm is 0.03-0.12 cc/g.
