Modelación de la transferencia de oxágeno en sistemas de aereación mediante un modelo de dos zonas simplificado

A new two zone simplified oxygen mass-transfer model with an analytical solution was proposed and used to analyze the unsteady state reaeration data of diffused reaeration systems in order to find the volumetric mass-transfer coefficients. Series of unsteady state reaeration tests in a 1000 l tank w...
