The aim of this paper is to prove the applicability of Auxipó as an auxiliary agent of coagulation for pulp and paper industry wastewater. Thus, it is possible to clarify the effluent more efficiently before launching it in waterbodies. To test the applicability of the auxiliary agent of coagulation, two coagulation and flocculation assay diagrams were developed: the first diagram only shows coagulant dosages, and the second diagram represents the coagulant and Auxipó dosage. Both tests demonstrated efficiency in turbidity removal; however, the results showed higher removal efficiency after the dosage of Auxipó.
