Inertización de lodos galvánicos para su incorporación a productos cerámicos

Abstract: Sludges produced by the physico-chemical treatments of waste waters generated by electroplating plants were physically and chemically characterised and incorporated in ceramic pastes. The influence of the amount of sludges added to a typical brick composition on the various processing steps and on the green and fired properties was studied. The environmental risks of the incorporation of these sludges rich in heavy metals such as Cr, Pb, Zn, Cu, Ni, etc. were evaluated by performing leaching tests on the fired… Show more

“…There are not many studies that describe production of commercial goods (Carneiro et al 2018). Articles (Costa et al 2008;Ferreira et al 1999;Abdurakhmanov et al 2000) present the results of using galvanic sludge in the production of ceramic products for various purposes such as clay bricks (Pérez-Villarejo et al 2015), cement clinker (Espinosa and Tenório 2000;Ract et al 2003), different glasses (Andreola et al 2006;Silva et al 2008), and obtaining pigments (Cheprasova and Zalyhina 2017;Andreola et al 2008).…”

“…It is therefore interesting to use different industrial waste in the manufacture of different construction materials, such as ceramic clay bricks. The ceramic industry presents enormous potential for the reuse and recovery of industrial waste [1,2,3,4,5,6,7]. The Spanish structural ceramic sector is the largest European producer, with about 30 million tons in 2007.…”

“…Assim, diversos trabalhos foram publicados com o objetivo de introduzir diferentes rejeitos durante a produção de tijolos comerciais. A quantidade adicionada varia com o tipo de rejeito, com o objetivo de manter as propriedades dos tijolos em níveis aceitáveis, de modo a atingir aos requisitos das especificações [4][5][6][7].…”

“…Dentro da área siderúrgica foi relatada a adição, à massa cerâmica, de finos de areia de fundição, escórias de siderurgia em geral (com adição isolada ou em conjunto com precipitados de estação de tratamento de águas de curtume), escórias de alto forno, lamas de rejeito de indústrias de eletrodeposição de metais. [5][6][7][8][9][10]. Ligados ao setor energético, foram reportadas adições de resíduos de estação de tratamento de efluentes de campos petrolíferos e cinzas de combustão de carvão [4,11,12].…”
