For this purpose, unplanted HSSF-CWs prototypes of equal volumes and length/width ratios (L W-1) of 1.0, 4.0 and 7.3 were used. All HSSF-CWs were filled with gravel # 0 and received sanitary sewage (SW) during a period of 90 days, in which the BOD and COD, in the total and soluble forms, were monitored in the influent and effluents from the system. These units were subject to tracer tests, before and after the HSSF-CWs received the SW, to obtain d. The MFOKM was adjusted to the COD and BOD experimental data. In all cases, an inverse relation was observed between n and the parameters d or with the organic matter decay rate obtained in the initial part of the HSSF-CWs. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200022 https://www.redalyc.org/journal/3032/303260200022/ https://www.redalyc.org/journal/3032/303260200022/html/ https://www.redalyc.org/journal/3032/303260200022/303260200022.epub https://www.redalyc.org/journal/3032/303260200022/movil https://doi.org/10.4025/actascitechnol.v41i1.36709 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
