Abstract: The invention relates to a method for cleaning liquids containing impurities. Adsorbents are added to the liquid, which adsorb the impurity. Several particles of adsorbent are agglomerated with the impurities adsorbed therein/thereon to form greater particles of adsorbent. The now greater particles of adsorbent are suspended in the liquid once again. The liquid containing the greater particles of adsorbent is then filtered. An apparatus possesses at least one agglomerator with a feed inlet, an outlet each for the separated components (clear runnings, concentrated suspension) and an apparatus for producing the agglomeration. The latter is preferably an apparatus for producing an electric field. A pressure filter with a feed inlet for the concentrated suspension and an outlet each for the separated components is further provided.

Abstract: In a method and apparatus for adsorptive cleaning of vegetable and/or mineral oils and fats operating by a multi-stage countercurrent process, in which uncleaned oil is fed to a first stage, where it is put into contact and pre-cleaned with an already used and partly loaded adsorptive agent, fed to a first separating stage, put into contact with fresh adsorptive agent at a second stage, and then fed to a second separating stage and in which the constituents removed from the oil at the second separating stage are re-utilised at the first step in the process, as an already used, partly loaded adsorptive agent, these constituents are obtained and/or prepared as a pumpable sludge and passed to the uncleaned oil in the first stage with air excluded.
