Abstract

BENDER, Ana Flávia; SOUZA, Jeanette Beber de  and  VIDAL, Carlos Magno de Sousa. Advanced treatment technologies for the removal of color and phenol from the effluent of paper industry wastewater. Ciênc. Florest. [online]. 2019, vol.29, n.2, pp.571-582.  Epub Sep 30, 2019. ISSN 0103-9954.  https://doi.org/10.5902/1980509832503.

This paper analyzes the removal of colour and phenol found in pulp and paper industry wastewater using advanced technologies: (i) coagulation-flocculation-sedimentation, (ii) granular activated carbon filtration, (iii) combination of coagulation-flocculation-sedimentation and granular activated carbon filtration. Jar tests and bench-scale column tests were performed. The main results obtained were: removals of 89% and 60% for colour and phenol, respectively, using coagulation-flocculation-sedimentation; for activated carbon filtration, overall colour and phenol removal of 45% and 47%, respectively; and maximum removals obtained were 99% for colour and above 93% for phenol, when the complete cycle (coagulation-flocculation-sedimentation combined with filtration) was tested. Along with this last treatment, it was possible to obtain a high-quality final effluent and to comply with the environmental regulations in several aspects.

Keywords : Industrial effluents; Tertiary treatment; Activated carbon.
