Resumo: This work aimed to investigate algal diversity at the genus level in stabilization pond systems treating domestic wastewater and to evaluate the feasibility of an electroflotation by alternate current (EFAC) system for simultaneous microalgae separation and cell disruption. Evaluation of algal diversity showed that the genera Euglena and Chlorella were present in relatively high frequencies in five of the six effluents analyzed. The use of EFAC on an effluent that presented bloom of Chlorella achieved turbidity and chlorophyll-a removal efficiencies higher than 70 and 90%, respectively, after 70 minutes of operation. Total lipid yield for the Chlorella-rich biomass was 21.4±2.02%. Such high biomass lipid content demonstrates the potential for obtaining lipid-based biofuels from wastes. The current paper describes the first attempt, with promising results, at using electroflotation by alternate current for low cost, simultaneous microalgae harvesting and disruption.

A avaliação de diversidade algal mostrou que os gêneros Euglena e Chlorella estiveram presentes com relativamente elevada frequência em cinco dos seis efluentes analisados. A aplicação de eletroflotação por corrente alternada em um efluente que apresentou elevada predominância de Chlorella alcançou eficiências de remoção de turbidez e clorofila-a maiores que 70 e 90%, respectivamente, depois de 70 minutos de operação. O rendimento de lipídios totais para a biomassa rica em Chlorella foi de 21,4±2,02%. Esse elevado teor lipídico demonstra potencial para obtenção de biodiesel de lipídios de efluentes. O presente artigo descreve uma primeira tentativa, com resultados promissores, da utilização de eletroflotação por corrente alternada para separação e ruptura celular simultânea com baixo custo.Engenharia sanitária e ambiental2022-07-21T19:13:23Z2022-07-21T19:13:23Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANTOS, A.
