Estimación directa del KLa mediante un algoritmo de optimización en un respirómetro nitrificante

Abstract

El coeficiente de transferencia de oxígeno volumétrico (KLa) fue estimado en un respirómetro nitrificante, mediante el ajuste directo de los datos experimentales de oxígeno disuelto a la ecuación diferencial de balance de oxígeno, usando un algoritmo de optimización basado en el método de Runge-Kutta y él de mínimos cuadrados. Los datos de oxígeno fueron obtenidos con el método dinámico de eliminación de gas (gassing-out). Los valores de KLa estimados con este algoritmo fueron comparados con valores de KLa estimados con el método gráfico. Los ajustes realizados a los datos experimentales de oxígeno con el algoritmo de optimización presentaron mejor correlación que los ajustes realizados con el método gráfico ya que la estimación directa no requiere el cálculo de las derivadas de oxígeno disuelto disminuyendo así el error en la estimación del KLa.

Keywords

KLa, nitrificación, método dinámico de eliminación de gas, Coeficiente de transferencia de oxígeno volumétrico, algoritmo de optimización
