PURPOSE:To separate and remove ash mixed with activated carbon by regenerating the activated carbon in a regenerating furnace, classifying it to obtain a regenerated product contg. activated carbon of a relatively small grain size and ash, and adding water to the regenerated product to settle the activated carbon. CONSTITUTION:Used activated carbon is regenerated in a regenerating furnace 35 and classified with a sieve 37 to obtain a regenerated product consisting of finely crushed activated carbon and ash. The regenerated product is slurrified with fresh water and sent to an ash separating tank 40. The ash in the regenerated product floats, and the activated carbon settles. The settled activated carbon is returned to an adsorption tower 31 through a pipe 41, and an upper layer contg. the ash is sent to an ash concentrating tank 43, where a cationic flocculant is added to flocculate and settle the ash.
