The filter material of the present invention is suitable for the activated carbon because the granular activated carbon has a large contact area with water and is excellent in adsorptivity and water permeability.

The pore structure of the granular activated carbon has the pore diameter>50nm macropores, also 2.0-50 nm mesopores and<2.0nm micropores with a polydisperse pore size distributionAnd many mesopores and macropores which do not contribute to adsorption are present therein. Most of the pores of the granular activated carbon for adsorption are not on the surface, and adsorbed molecules can be adsorbed by micropores only by diffusion of macropores and mesopores, so that the adsorption speed is low. Therefore, granular activated carbon can adsorb adsorbates having a large molecular weight, but has poor adsorbability to adsorbates having a small molecular weight.
