摘要

"Processes for the clarification of water of tailings, for the removal of water in water of tailings, and to improve the retention and drainage of water from the process in production of pulp and paper.The invention is a process for clarification.Removal of water or for improving retention and drainage of industrial waste water and application of dressings of paper with a quantity effective to at least a dispersion of a flocculant CATIu00f3nico polymer soluble in water in which the improvement comprises the addition of said polymer that has a concetrau00e7u00e3o of at least twenty five percent for the so-called water of tailings or dressings papeL.Industrial waste is preferably waste water of food processing.The waste water oily water of paper mill tailings and tailings water contaminated by inorganic components. The finishing of paper may be a cellulosic suspension in water.
