Resumo: This study was carried out in order to evaluate treatment systems for removal of solids and organic material of the water (ARC) in way to make possible its recirculation in the coffee fruits processing. The recirculation of ARC was operated in four circuits: short circuit, without screen (CC-SP), when the ARC was recirculated without any treatment; short circuit, with screen (CC-CP), when the ARC went by a pressurized mesh screen; long circuit, without screen (CL-SP), when the ARC went by a decantation tank; and long circuit, with screen (CL-CP), when the ARC went by pressurized mesh screen and later for the decantation tank. The screen, included to ARC treatment system, showed low efficiency in removing CE, ST, SS, DBO and DQO, not resulting in significant effects in the quality of the water in recirculation. However, the decantation tank was more efficient in the removal of the analyzed variables. The circuit CL-CP presented small increment in the removal efficiencies, compared to CL-SP, not justifying the inclusion of the screen in the process. Thus the obtained data evidence the application only the decantation tank is sufficient in the ARC treatment for recirculation in the coffee fruits (Coffea arabica L.) processing.

O sistema de recirculação da ARC foi operado em quatro circuitos: circuito curto, sem peneira (CC-SP), no qual a ARC era recirculada sem nenhum tratamento; circuito curto, com peneira (CC-CP), no qual a ARC passava por uma peneira pressurizada de malha; circuito longo, sem peneira (CL-SP), no qual a ARC passava por um tanque de decantação; e circuito longo, com peneira (CL-CP), no qual a ARC passava pela peneira de malha e depois pelo tanque de decantação. A peneira, incluída ao sistema de tratamento da ARC, apresentou baixa eficiência na remoção de CE, ST, SS, DBO e DQO, não resultando em efeitos significativos na qualidade da água em recirculação. Entretanto, o tanque de decantação foi eficiente na remoção das variáveis analisadas. O circuito CL-CP apresentou pequeno acréscimo nas eficiências de remoção, quando comparado ao CL-SP, não justificando a inclusão da peneira de malha no processo. Com base nos resultados obtidos, verificou-se que apenas o tanque de decantação é suficiente no tratamento da ARC, para fins de sua recirculação no processamento dos frutos do cafeeiro (Coffea arabica L.).Editora UFLA2008-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/69Coffee Science - ISSN 1984-3909; Vol. 3 No. 1 (2008); 19-29Coffee Science; Vol. 3 Núm. 1 (2008); 19-29Coffee Science; v. 3 n. 1 (2008); 19-291984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporenghttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/69/138https://coffeescience.ufla.br/index.php/Coffeescience/article/view/69/139Copyright (c) 2008 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRaggi, Luiz Gustavo de RezendeMatos, Antonio Teixeira deLuiz, Fátima Aparecida Resende2013-02-23T12:45:29Zoai:coffeescience.ufla.br:article/69Revistahttps://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:2024-05-21T19:53:28.996444Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
