ABSTRACT:
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.
