Approximate method for designing a primary settling tank for wastewater treatment / Gloria Martínez-González in Industrial & engineering chemistry research, Vol. 48 N° 16 (Août 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 16 (Août 2009) . - pp. 7842–7846 Titre : Approximate method for designing a primary settling tank for wastewater treatment Type de document : texte imprimé Auteurs : Gloria Martínez-González, Auteur ; Herbert Loría-Molina, Auteur ; David Taboada-López, Auteur Année de publication : 2009 Article en page(s) : pp. 7842–7846 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Analogous  Fick’s  law  mass  transport  model  Wastewater  treatment Résumé : An approximate method based on an analogous Fick’s law mass transport model was derived to predict the concentration profiles of suspended particles in a primary sedimentation tank for wastewater treatment as a function of time and column height. A pilot sedimentation column was constructed to test wastewater sedimentation and obtain the necessary data for the proposed model. The examined variables included the total suspended solids concentration, the sedimentation height, and the time elapsed. Computer code was developed to estimate the dispersion coefficient present in the sedimentation model from experimental data via least-squares regression, resulting in a relative error of 3.705%. The proposed model was validated by good agreement with reported data in the literature. The basic dimensions for designing a primary sedimentation tank were obtained based on the experimental data from wastewater samples obtained by a wastewater collector located in the industrial zone of Celaya City, México. This methodology can be successfully applied for designing primary sedimentation tanks for wastewater treatment facilities.
