Abstract
In the purification of oil used for example in light metal rolling, and contaminated by abraded particles, a coagulating agent, for example an aqueous soda solution, is added by means of a dosaging device (7) and mixed in a device (5) which comprises a static dispersing device (8) with a jet pump (9) connected thereafter with a recirculation loop (10). The mixing is normally carried out at an elevated temperature and a heating step (3,4) included. After mixing, the coagulates formed are separated, typically in a centrifuge (14). The invention is particularly suited to the purification of the rolling oil occurring in the manufacture of aluminium foils.
