Abstract

THE INVENTION COMPRISES A METHOD FOR CLARIFYING INK-LADEN WATER OBTAINED FROM THE RECYCLING OF PAPER STOCKS BY TREATING SAID WATER WITH A HYDROPHILIC DISPERSION POLYMER. THE HYDROPHILIC DISPERSION POLYMER OF THE INVENTION IS A COPOLYMER OF A DIALLYL N,N-DISUBSTITUTED AMMONIUM HALIDE CATIONIC MONOMER AND (METH)ACRYLAMIDE (ACAM). FOLLOWING DOSING WITH THE POLYMER, A FLOC IS FORMED. THE FLOC CONTAINS INK AND IMPURITIES WHICH ARE REMOVED FROM THE WATER PROCESS STREAM BY MEANS OF SOLID LIQUID SEPARATION; THE SOLID LIQUID SEPARATION COMPRISING A DISSOLVED AIR FLOTATION METHOD. A PREFERRED COPOLYMER IS FORMED FROM DADMAC AND ACAM.
