MALDONADO-MALDONADO, Julio Isaac et al. Model development for the design of an anaerobic upflow filter separated in two and three phases. Dyna rev.fac.nac.minas [online]. 2018, vol.85, n.207, pp.44-53. ISSN 0012-7353. https://doi.org/10.15446/dyna.v85n207.69783.
In this study, the development of models for the design of an anaerobic upflow filters separated into two and three phases are presented, DI-FAFS and TRI-FAFS. Both reactors have been evaluated in the COD removal performance on a total of 54 tests. The experimental factors are the volumetric organic load, the temperature and the depth relationship between two consective phases. The conceptual model is based on equations derived from a mass balance under stationary conditions dS/dt = 0 and advectives dS/dZ ( 0; eight equations applicable to the DI-FAFS and TRI-FAFS reactors; four equations for each reactor.The equations to obtain the parameters of degradation of organic matter were compared with bibliographic references. Two models were selected and proposed, after adjusted to observations with R2 adjusted greater than 0.7 and with standard errors of estimation and the absolute average error in the minimum values.
