Resumo: The issue of this work was to assess the efficiency of aeration systems in cascades for the treatment of wastewater from the processing of coffee fruits. The aeration system was installed in cascades of a level difference of 4.14 m from the ground with 23 steps (height, width and length of 0.18, 0.32 and 0.60 m, respectively.) Samples of influent and effluent, after system operating with three recirculations per day, over a period of 10 days, were analyzed. The average removal efficiency of COD was 28.9 % during the experiment, the removals of total solids, total volatile solids, total suspended solids, volatile suspended solids, nitrogen, phosphorus, potassium and phenolic compounds were 57.3, 71.6, 26.5, 17.2, 35.7, 62.5, 49.5 and 55 % respectively. The cascade aeration proved to be an important alternative for composition the ARC treatment systems, with a view that is effective means of low cost and relatively fast for the aerobic treatment of organic material present in those wastewaters.

No final da cascata foi instalado um reservatório para recepção/detenção da ARC escoada, de onde, após um tempo de detenção de 3 horas e transferência para um reservatório de distribuição, era recirculada no sistema. Amostras do afluente e efluente, após sistema operar com 3 recirculações por dia, num período de 10 dias, foram coletadas e analisadas. De acordo com os resultados obtidos, pôde-se concluir que a eficiência de remoção média de DQO foi de 28,9 % durante o experimento; as remoções de sólidos totais, sólidos voláteis totais; sólidos suspensos totais, sólidos suspensos voláteis, nitrogênio, fósforo, potássio e compostos fenólicos foram de 57,3; 71,6; 26,5; 17,2; 35,7; 62,5; 49,5 e 55 %, respectivamente. A cascata de aeração mostrou ser importante alternativa para composição de sistemas de tratamento da ARC, tendo em vista que é meio efetivo de baixo custo e de relativamente rápido tratamento aeróbio do material orgânico presente nessas águas residuárias.Editora UFLA2014-10-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/zipapplication/zipapplication/mswordapplication/x-rarhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/708Coffee Science - ISSN 1984-3909; Vol. 9 No. 4 (2014); 435 - 444Coffee Science; Vol. 9 Núm. 4 (2014); 435 - 444Coffee Science; v. 9 n. 4 (2014); 435 - 4441984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/708/pdf_125https://coffeescience.ufla.br/index.php/Coffeescience/article/view/708/1286https://coffeescience.ufla.br/index.php/Coffeescience/article/view/708/1287https://coffeescience.ufla.br/index.php/Coffeescience/article/view/708/1288https://coffeescience.ufla.br/index.php/Coffeescience/article/view/708/1289Copyright (c) 2014 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessEustáquio Júnior, ValdeirTeixeira de Matos, AntonioAlfonsa Vieira Lo Monaco, PaolaPimentel de Matos, Mateus2014-10-11T18:41:58Zoai:coffeescience.ufla.br:article/708Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:47.819540Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
