Zusammenfassung:	To provide a cleaning method of a colloidal solution removing colloid (a harmful component mainly containing an ultra fine particular solid article with 10 micron or less) generated in metal processed water such as a plating liquid, including a turbidity component generated in a process using edible oil for fried foods, mechanical oil or the like, and a device therefor.SOLUTION: Fine fibrous cellulose is spread, preferably porous absorbent uniformly including a power ion exchange resin, and a colloid liquid, for example deteriorated tempura oil are contact reacted to store impurities, and then the porous absorbent is classified by a centrifugal separator or a deep bed filtration method.SELECTED DRAWING: None 【課題】揚げ物用食物油や機械油等を使用する過程で生成する濁り成分を始め、メッキ液等の金属加工水に生成するコロイド（１０ミクロン以下の超微粒子状固形物を主体とする有害成分）を除去するコロイド溶液の浄化方法とその装置を提供する。【解決手段】微小繊維状セルローズを展着し、好ましくは粉末イオン交換樹脂を均一に包含した多孔性吸着体、と例えば劣化した天ぷら油などのコロイド溶液とを接触反応させて不純物を吸蔵させた後、遠心分離機や深層濾過法で前記多孔性吸着体を分別する。【選択図】なし
