Resumo: | The latex paint industry uses drinkable water on a large scale in its process. After used, it goes to effluent treatment plants (ETP), generating a sludge as a by-product. Currently, this residual sludge is disposed in co-processing furnaces, which creates a problem due to the high costs associated with this process This study aims to evaluate the viability of using the ETP sludge from a local latex paint industry as a substrate in the farming of Lobularia maritime. In total, five treatments composed by different amounts of sludge and substrate were performed, one being the control, containing 0% of sludge, and the others in the proportions of 10%, 20%, 30%, 40% (substitution in volume of substrate for sludge). The sludge samples and the five treatments were characterized by pH, electrical conductivity (EC), total content of soluble salts (TCSS), bulk and dry density, moisture content and particle size distribution analyses. In addition to the previous mentioned analyses, for the sludge samples, X-ray fluorescence analyses (XRF), thermo-gravimetric analysis (TGA/DTG) and specific mass determination were also performed, and for the treatments studied, analyses of porosity, water retention capacity and plant growth were carried out. In all treatments evaluated, the results of EC and pH were within the parameters established by the literature. The chemical analysis showed that the sludge is composed mainly of calcium (Ca), titanium (Ti), silicon (Si), aluminum (Al) and iron (Fe). As for the physical characterization, it was found that the incorporation of the residue results in an increase in density and a decrease in moisture content and in the average diameter of the system particles, negatively affecting the water retention capacity, total porosity and, possibly, the amount of micropores. All treatments showed plantular development, concluding that, when used in low proportions (up to 10% v:v), the sludge has potential use as a partial substitute material for substrate to produce seedlings. |

Após o uso, esse insumo segue para estações de tratamento de efluentes (ETE), gerando como subproduto um lodo. Atualmente, o descarte desse lodo residual se dá através de envio para fornos de coprocessamento, o que gera uma problemática devido aos custos elevados associados a este processo. O presente trabalho tem como objetivo avaliar a viabilidade de utilização do lodo da ETE de uma empresa de tintas látex como substrato para a produção e cultivo de Lobularia maritime. Para isso, foram realizados cinco tratamentos, compostos por diferentes quantidades de lodo e substrato, nas proporções 10%, 20%, 30%, 40% (substituição em volume de substrato por lodo) e uma testemunha, 0% de lodo. As amostras de lodo e os cinco tratamentos foram caracterizados quanto ao pH, condutividade elétrica (CE), teor total de sais solúveis (TTSS), densidade aparente e seca, teor de umidade e granulometria. Para as amostras de lodo, além das análises supracitadas, foram realizadas, ainda, as análises de fluorescência de raio X (FRX), análise termo-gravimétrica (TGA/DTG) e determinação da massa específica. Nos tratamentos estudados, foram também realizadas as análises de porosidade, capacidade de retenção de água e desenvolvimento plantular. Os resultados de condutividade elétrica e pH, encontraram-se dentro dos parâmetros estabelecidos pela literatura em todos os tratamentos avaliados. A análise química mostrou que o lodo é composto majoritariamente por cálcio (Ca), titânio (Ti), silício (Si), alumínio (Al) e ferro (Fe). Quanto à caracterização física, verificou-se que a incorporação do resíduo resulta no aumento da densidade e diminuição do teor de umidade, assim como, do diâmetro médio das partículas do sistema, afetando negativamente a capacidade de retenção de água, porosidade total e, possivelmente, a quantidade de microporos. Todos os tratamentos apresentaram desenvolvimento plantular, concluindo-se que, quando utilizado em baixas proporções (até 10% v:v), o lodo apresenta potencial uso como material substituto parcial de substrato para a produção de mudas.UFSC - Federal University of Santa Catarina2021-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/490410.29183/2447-3073.MIX2022.v8.n1.117-133Mix Sustentável; Vol. 8 No. 1 (2022): Mix Sustentável (edição regular); 117-133MIX Sustentável; v. 8 n. 1 (2022): Mix Sustentável (edição regular); 117-1332447-30732447-0899reponame:Mix Sustentável (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/4904/3832Copyright (c) 2021 Luize Kehl Bickel, Marina Remião dos Santos, Regina Célia Espinosa Modolo, Iara Janaína Fernandes, Bethânia Brochierinfo:eu-repo/semantics/openAccessBickel, Luize Kehldos Santos, Marina RemiãoBrochier, BethâniaFernandes, Iara JanaínaModolo, Regina Célia Espinosa2022-12-07T16:50:45Zoai:ojs.sites.ufsc.br:article/4904Revistahttp://mixsustentavel.paginas.ufsc.br/apresentacao-2/PUBhttp://ojs.sites.ufsc.br/index.php/mixsustentavel/oailisiane.librelotto@ufsc.br||mixsustentavel@gmail.com2447-30732447-0899opendoar:2022-12-07T16:50:45Mix Sustentável (Online) - Universidade Federal de Santa Catarina (UFSC)false |
