Utilização de biopolímero no tratamento de efluentes da indústria de papel e celulose por Processo Oxidativo Avançado

Abstract: ResumoA indústria de papel e celulose produz elevado volume de efluente, o qual geralmente apresenta alto valor de cor e concentração de matéria orgânica. A maioria dos componentes presentes no efluente são difíceis de eliminar por processos convencionais de tratamento de águas residuárias. Neste contexto, estudos de alternativas que melhorem significativamente a qualidade do efluente e que representem minimização dos impactos associados à disposição deste no ambiente são necessários. Dentre tais alternativas,… Show more

“…As claimed by the authors, advantages to the industry are pointed out, such as the recovery of water for use in periods of drought, the reduction of effluent discharges into bodies of water, the recovery of useful chemical products for the treatment of effluents or factories of pulp and paper and, finally, the reduction of water consumption per ton of product produced. On the other hand, considering the oxidative processes to water reuse, Souza et al (2017) highlight that the use of the Fenton process resulted in a reduction of 74.9% in COD and 87.2% in total phenols. According to Tambosi (2005), in combined coagulation and flocculation processes followed by UV radiation and application of hydrogen peroxide (H2O2), 60% of total COD removal was obtained.…”
