Method for purifying contaminated liquids

摘要

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.
