DADMAC/vinyltrialkoksysilan-kopolymerer og anvendelse av disse ved behandling av avlöpsvann

摘要

The invention is a water-soluble, surface active silicon-containing polyelectrolyte polymer and its use as coagulants for the control of pitch in pulp and paper mills; in clarifying ink-containing effluent water from recycled paper production; for removing color from a paper mill waste effluent containing color-bodies; for clarifying wastewater containing turbidity-causing components; for a chemical treatment method that effectively removes fat, blood, tissue and other solids from food processing waste and for removing waste oil from industrial oily wastewater. These polyelectrolyte polymers are silicon containing copolymers of specific hydrophilic or hydrophobic monomers, preferably diallyl dimethyl ammonium halides, particularly diallyl dimethyl ammonium chloride and vinyl alkoxysilanes, preferably vinyl trimethoxysilane.
