Clarification of deinking process water |
摘要 |
The invention is a method for clarifying ink-containing effluent water from recycled paper production which comprises the step of adding a water-soluble, surface active, silicon-containing polyelectrolyte polymer coagulant to the ink-containing effluent water from recycled paper production, wherein the polymer has from 0.01 to 10 mole percent of a vinyl alkoxysilane monomer. A preferred silicon-containing polyelectrolyte polymer is the product of a free radical synthesis from vinyltrimethoxysilane and diallyldimethylammoniumchloride monomers.
