Eliminación de coliformes fecales en lagunas anaerobias utilizando un método gráfico.

Anaerobic lagoons remove organic matter in the absence of oxygen and must be designed considering facultative or aerated lagoons, to continue with the treatment and at the same time re-oxygenate the wastewater. The purpose of this document is to determine two graphs to calculate the elimination of fecal coliforms in anaerobic lagoons. An application example is included with the traditional method adopted by the Instituto Mexicano de Tecnología del Agua y la Comisión Nacional del Agua, later the graphs previously prepared are used. The results show the same values calculated with the traditional criteria. [ABSTRACT FROM AUTHOR]
