Methane production in single phase and biphase reactors using modeled soluble coffee water
The objective of this research was to establish the production of methane in reactors with a Monophasic System (SM) and a Biphasic System (SB) using modeled water from the soluble coffee industry as a substrate, with a chemical oxygen demand (COD) of 7,5 g / L, considered as a waste with a high orga...

| description | The objective of this research was to establish the production of methane in reactors with a Monophasic System (SM) and a Biphasic System (SB) using modeled water from the soluble coffee industry as a substrate, with a chemical oxygen demand (COD) of 7,5 g / L, considered as a waste with a high organic load. The laboratory tests were performed in reactors fitted with an Upflow Anaerobic Filter (UAF), evaluating parameters of: pH, relationship between volatile fatty acids and alkalinity (FOSTAC), COD removal, concentration and methane yield, applying standardized methods for the analysis of wastewater described by APHA & WPCF, 2012. In the yield variable, the SM showed average values of 0,15 dm³ CH₄ / gDQO in comparison to those exhibited by the SB with average values of 0,26 dm³ CH₄ / g COD, the operating ranges of the SB were: pH (6,38-8, 0), FOSTAC (0,42-0,60), AGV (160-423mg / l), COD removal (61-85%); where it was statistically verified that the methane productions in the evaluated systems differ significantly (p <0,05), evidencing that the mean methane production values increased by 70% in relation to the SM. |

Las pruebas de laboratorio se realizaron en reactores provistos con filtro anaeróbicos de flujo ascendente (FAFA), evaluando parámetros de: pH, relación entre ácidos grasos volátiles y alcalinidad (FOSTAC), remoción DQO, concentración y rendimiento de metano, aplicando métodos normalizados para el análisis de aguas residuales descrita por APHA y WPCF, 2012. En la variable rendimiento el SM mostró valores promedios de 0,15 dm³ CH₄/gDQO en comparación a los exhibidos por el SB con valores promedios de 0,26 dm³ CH₄/g DQO, los rangos de operación del SB fueron: pH (6,38-8,0), FOSTAC (0,42-0,60), AGV(160-423 mg/l), remoción DQO (61-85%); donde se comprobó estadísticamente que las producciones de metano en los sistemas evaluados difieren significativamente (p<0,05), evidenciando que en el SB se incrementó los valores promedios de producción de metano del 70% en relación al SM.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2021-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por paresapplication/pdftext/htmlapplication/ziphttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/24310.51260/revista_espamciencia.v12i2.243Revista ESPAMCIENCIA; Vol. 12 Núm. 2 (2021): REVISTA ESPAMCIENCIA 2021; 84-941390-8103reponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/243/279https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/243/377https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/243/551http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccess2025-02-25T14:40:11Zoai:espamciencia.espam.edu.ec:article/243Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:40:11Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
