Resumo: The present study describes the alternative treatments applied to the secundary effluent of a bleached kraft process pulp industry. The effluent  samples were analysed in relation to their contents of chloride and trace elements (zinc, copper, lead and cadmium), and submitted to a treatment with aluminium sulphate or iron chloride, as floculants, using further, solid residues of industrial process (dreg, grit and heavy ash) and active carbon, as coagulation adjuvants. A significant reduction of the contents of chloride and trace elements in the final effluent was observed by the combined use of aluminium sulphate/active coal 2 and iron chloride/industrial residues, respectively.

O presente estudo descreve os tratamentos alternativos a que foi submetido o efluente secundário de uma indústria de celulose kraft branqueada. As amostras do efluente foram analisadas quanto ao teor de cloretos e  de elementos-traço (zinco, cobre, chumbo e cádmio) e, a seguir, foram tratadas com sulfato de alumínio ou cloreto férrico, como floculantes, utilizando-se, ainda, resíduos sólidos do processo industrial ("dreg", "grit", cinza pesada) e carvão ativo, como auxiliares de floculação. Foi observada uma significativa redução do teor de cloretos e de elementos-traço nos efluentes finais, com o uso combinado de sulfato de alumínio/carvão ativo 2 e cloreto férrico/resíduos industriais, respectivamente.Universidade Federal de Santa Maria1996-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33110.5902/19805098331Ciência Florestal; Vol. 6 No. 1 (1996); 129-136Ciência Florestal; v. 6 n. 1 (1996); 129-1361980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/331/199Frizzo, Sônia Maria BitencourtSilva, Maria Cládis Mezzomo daFoelkel, Celso Edmundo B.info:eu-repo/semantics/openAccess2017-06-14T13:50:47Zoai:ojs.pkp.sfu.ca:article/331Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-14T13:50:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
