Procedures based on the reuse of solid residues and the surplus of process chemicals for the tertiary treatment process of the Riocell S.A. (Guaíba, RS. - Brazil), are described. The effluent samples were characterized in relation to their color and content of organ-halogenated compounds and then submitted to a conditioning step with the application of two different flocculants using solid residues of process ("dreg", " grit", ashes) and active carbon as coadjuvants. An appreciable reduction of the color and content in organ-halogenated compounds was observed, as well as a economy on costs with flocculants.
