A filter media was developed comprising ionic activated cellulosic material with enormous sorption activity to ions-active dissolved and colloidal substances in aqueous systems evoking so-called surface flocculation and a filling material having a filter effect. The dilemma of the art of low sorption efficiency and high flow rate of filtrated aqueous dispersions without sacrificing its separation efficiency of fines has been solved by use of activated cellulosic material having multi-fold (roughly tenfold to hundredfold) sorption capacity for ions-active dissolved and submicron particulate contaminants compared to untreated cellulosic material.
