<p>The invention relates to a method for flocculating aqueous dispersions of high salinity and high dry solids content in the presence of a dicyandiamide condensate and a cationic, non- ionic or amphiphilic acrylamide polymer. Further, the invention relates to the use of said dicyandiamide-formaldehyde condensate and said acrylamide polymer for flocculating drilling mud, bio-fermentation sludge and landfill-leachate.</p> |
