Abstract

Provided is a granular activated carbon which has a filtered flow rate of a predetermined value or higher, and a high water purification performance; and a method for manufacturing the same. A granular activated carbon comprises a plurality of activated carbon granules and a binder for binding the plurality of activated carbon granules, wherein the binder is composed of net-like fibers. Also, a method for manufacturing the granular activated carbon includes a step for spraying and drying slurry which is obtained by dispersing the activated carbon granules and the fibers in water.

Claims (11)

1 . A granular activated carbon, comprising:

a plurality of granule-shaped activated carbons; and

a binder for binding the plurality of granule-shaped activated carbons,

wherein the binder is composed of net-like fibers.

2 . The granular activated carbon of claim 1 ,

wherein the fibers are bound by being entangled with the granule-shaped activated carbons on a surface of the granular activated carbon and inside the granular activated carbon.

3 . The granular activated carbon of claim 1 , wherein the fibers are contained in the granular activated carbon by 1 volume % to 5 volume %.

4 . The granular activated carbon of claim 1 , wherein the fibers are fibril fibers.

5 . The granular activated carbon of claim 1 , wherein the fibers are nanofibers.

6 . The granular activated carbon of claim 1 , wherein a central granule diameter of the granule-shaped activated carbons is 40 μm or less.

7 . The method for manufacturing the granular activated carbon of claim 1 , the method comprising a step for spraying and drying slurry which is obtained by dispersing the granule-shaped activated carbons and the fibers in water.
