Abstract

The invention relates to a method of purifying liquids, which contain impurities such as oil or dissolved metals. The liquid is first mixed with a finely-divided particulate sorbent to form a suspension, in which impurities are adsorbed or absorbed by the sorbent particles, to form a premixed suspension. A flow of this suspension is then directed substantially tangentially towards a surface of a porous filtering element (7), whereby part of the liquid penetrates through the filtering element and is removed through a filtrate outlet as purified liquid filtrate (8). The tangential flow keeps the filtering element (7) unblocked, and the sorbent, together with the rest of the liquid travels along the surface of the filtering element to be removed through a retentate outlet (9). The method is even useful for clarifying the liquid by removal of finely-divided solid impurities.
