Zusammenfassung:	PURPOSE: To facilitate the removal of metal ions and corrosive products with filtration efficiency improved using a filter having an increased pore size by adding a metal ion precipitator and a coagulant to the used brine and filtering the precipitate formed. CONSTITUTION: To a used brine or an antifreezing mixture, are added a metal ion precipitator (which reacts with metal ions to form insoluble substance), for example, sodium dimethyldithiocarbamate, N,N'-dimethylthiourea, 2- mercaptobenzothiazole or benzotriazole and a coagulant (which coagulates fine particles of metal ion precipitate), for example, sodium alginate, polyacrylamide polymer in a concentration of 1-50mg/l. Then, they are filtered through a filter having a pore diameter more than 1μm to regenerate brine or the like.
