In this work we have assessed the decolorization of textile effluents throughout their treatment in a solid-state fermentation (SSF) system. SSF assays were conducted with peach-palm (Bactris gasipaes) residue using the white rot fungus Ganoderma lucidum EF 31. The influence of the dye concentration and of the amounts of peach-palm residue and liquid phase on both the discoloration efficiency and enzyme production was studied. According to our results, independently of experimental conditions employed, laccase was the main ligninolytic enzyme produced by G. lucidum. The highest laccase activity was obtained at very low effluent concentrations, suggesting the existence of an inhibitory effect of higher concentrations on fungal metabolism. The highest percentage of color removal was reached when 10 grams of peach palm residue was moistened with 60 mL of the final effluent. In control tests carried out with the synthetic dye Remazol Brilliant Blue R (RBBR) decolorization efficiencies about 20% higher than that achieved with the industrial effluent were achieved. The adsorption of RBBR on peach-palm residue was also investigated. Equilibrium tests showed that the adsorption of this dye followed both Langmuir and Freundlich isotherms. Hence, our experimental results indicate that peach-palm residue is suitable substrate for both laccase production and color removal in industrial effluents.

Marcel Jefferson GonçalvesA mathematical model for a co-current moving bed heat exchanger (MBHE) is presented. The bed is diluted and composed of spheres of uniform radius which are transported by a dragging fluid in plug flow. The gas-solid mixture is heated indirectly by a flue gas, which flows in a jacket around the MBHE. Intraparticle temperature gradients and thermal losses to the external environment are considered. The model is solved analytically by the Self-Adjoint Operator method (SAO) and numerically by a combination of the Finite Analytical (FA) and the Finite Difference (FD) method. The results show excellent agreement and the comparison with experimental data validates the model, enabling its use in the design and analysis of MBHEs for which thermal losses are a relevant factor. MBHE effectiveness is defined, and it is shown - for a selected case - that the addition of 5.0 cm thick glass wool raises it by 25.5%.
About Me
D. in Environmental Engineering (FURB, 2022), M.Sc. in Chemical Engineering from the Federal University of Santa Catarina (UFSC, 2007), and B.Sc. in Chemical Engineering from the Regional University of Blumenau (FURB, 2003). Currently, he is a Full Professor in the Department of Chemical Engineering at FURB, where he has taught the following courses since 2010: Textile Engineering, Textile Technology, Textile Processes, Water and Wastewater Treatment, Unit Operations Laboratory, and Chemical Reactors. He also serves as a Full Professor in the Graduate Programs in Environmental Engineering and Chemical Engineering. His research focuses on textile processing (natural dyeing) and textile wastewater treatment (electrolytic processes and bioremediation by fungi and bacteria). He has extensive industrial experience, having worked for 26 years in the textile industry in R&D, Production, Quality Control, and Wastewater Treatment. Additionally, he spent 7 years in chemical companies in Technical Sales Consulting, focusing on the development and application of dyes, preparation, dyeing, and textile finishing auxiliaries, as well as chemical products for water and wastewater treatment. During his M.Sc., he worked on the development of chemical and biotechnological processes, applying at pilot and industrial scales a biological process for color removal from textile effluents.
