Avaliação da utilização das cinzas da escuma gerada em Reator Anaeróbico de Manta de Lodo e Fluxo Ascendente como pigmento inorgânico de coloração alaranjada

Abstract: RESUMOA escuma é um resíduo gerado durante o tratamento anaeróbico de efluentes domésticos que necessita de periódica remoção para não comprometer a eficiência do processo. O presente trabalho teve por objetivo utilizar as cinzas da escuma gerada em Reator Anaeróbico de Manta de Lodo e Fluxo Ascendente (RALF) como pigmentos inorgânicos. Amostras de escumas coletadas em diferentes meses foram submetidas a tratamento térmico a 900°C por 1h para remoção da matéria orgânica. As cinzas obtidas foram desaglomeradas … Show more

“…Nevertheless, in practice, since the use of the compost could be quite limited in eld scale applications due to limited availability throughout the entire operational period of the land ll, the search for alternative materials with equally good characteristics as an amendment to the cover soil, has become a major concern of researchers [18]. Scum is one of the main solid by-products produced during the steps of municipal wastewater treatments, and as such represents a great environmental liability for the wastewater treatment plants (WWTP), land lls frequently being its nal destination, with no exploitation of this residue [39,40]. Since it presents high organic matter and nutrient contents, and has already been sent to the land ll, scum could be evaluated as a potential amendment, thus enhancing its disposition in the land ll.…”
