Resumo: Solidification/Stabilization (S/S) is an important technique used in waste treatment, due its low cost and easily processing. The aim of this study was to optimize and standardize the S/S process in a Brazilian company. The packing of the dangerous residue was done using a mixture of different solidifying agents, such as: clayey soil; superabsorbent polymer (SAP)/cellulose pulp (fluff) and sanding powder. It was evaluated the effect of different amount of solidifying agent over the volume of packed mixture, the final moisture and the cost of the S/S process, using a Central Composite Design.  The results showed a minimum cost for the S/S operation of R$ 192.89/ton of liquid waste, using about 71.69 tons of clay soil for each ton of untreated residue, allowing a highly packed residue with a moisture up to 20% (w.b.).

Este trabajo propuso optimizar y estandarizar el proceso S/S en una empresa brasileña. Para este propósito, se estudió la compactación de residuos peligrosos utilizando mezclas de diferentes materiales como agentes solidificantes: tierra arcillosa, un polímero superabsorbente (pulpa de celulosa) y papel de lija. El efecto de la masa de los solidificadores sobre el volumen de la mezcla compactada, la humedad final y el costo del proceso de S/S se evaluó mediante la Planificación del Compuesto Central. Los resultados mostraron un costo mínimo de R$ 192,89/ton del resíduo, utilizando 71,69 ton del la tierra arcillosa por ton del reiduo, lo que permitió un residuo tratado con un alto grado de compactación y humedad final inferior al 20% (b.u.).A Solidificação/Estabilização (S/S) é uma técnica importante no tratamento de resíduos perigosos, devido ao seu baixo custo e fácil processamento. O objetivo deste trabalho foi otimizar e padronizar o processo S/S em uma empresa brasileira. Para tal, estudou-se a compactação do resíduo perigoso usando misturas de diferentes materiais como agentes solidificantes: solo argiloso, um polímero superabsorvente (polpa de celulose) e pó de lixa. Foi avaliado o efeito da massa dos solidificantes sobre o volume da mistura compactada, umidade final e o custo do processo de S/S empregando um Planejamento Composto Central. Os resultados mostraram um custo mínimo de R$ 192,89/ton de resíduo líquido, usando cerca de 71,69 (ton de solo argiloso)/(ton resíduo),  com uma umidade final menor que 20% (b.u.).Research, Society and Development2020-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/299710.33448/rsd-v9i4.2997Research, Society and Development; Vol. 9 No. 4; e144942997Research, Society and Development; Vol. 9 Núm. 4; e144942997Research, Society and Development; v. 9 n. 4; e1449429972525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/2997/2243Copyright (c) 2020 Sayeny Avila Gonçalves, Rafaela Cristina Sanfelice, Kassia Graciele Santosinfo:eu-repo/semantics/openAccessGonçalves, Sayeny de AvilaSanfelice, Rafaela CristinaSantos, Kassia Graciele dos2020-08-20T18:07:16Zoai:ojs.pkp.sfu.ca:article/2997Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:21.798825Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
