Caracterização físico-química e determinação de coeficientes cinéticos aeróbios de remoção da matéria orgânica de águas residuárias agroindustriais

Abstract: RESUMO Os objetivos do presente trabalho foram realizar uma caracterização físico-química de diferentes águas residuárias agroindustriais (ARA) e aplicar modelos cinéticos de primeira e de segunda ordem para verificar qual deles descreve melhor a progressão da demanda bioquímica de oxigênio (DBO) e para determinar coeficientes cinéticos aeróbios de remoção da matéria orgânica das ARA. Efetuou-se o ensaio de progressão da DBO pela incubação de ARA em um sistema respirométrico (Oxitop®). Os modelos cinéticos de … Show more

“…Due to agro-industry growth, there is an increasing generation of liquid organic waste, such as agricultural and agro-industrial wastewaters (AWWs), in production processes and related activities. These residues cause environmental impacts when they are not treated and disposed of properly, which contributes to soil, air and water pollution, contributing to the eutrophication of water bodies, in addition to causing possible harm to human and animal health (Dornelles et al, 2017;Morais et al, 2020b). Only dairy wastewaters generated worldwide, for example, have a polluting potential equivalent to 60% of the world population (Silva et al, 2020a).…”

“…A agroindústria é uma das principais fontes na geração de resíduos, como as águas residuárias (MORAIS et al, 2020). Nas pequenas agroindústrias de beneficiamento do açaí estão presentes sete etapas que compreendem todo processamento, são elas: descarregamento, lavagem, amolecimento, despolpamento, filtragem e embalagem e congelamento (FARIAS NETO, 2010).…”
