Determination of kinetic constants of bacterial abatement in facultative stabilization lagoons of the province of Mendoza and air – water temperature correlation model

Abstract

Stabilization Lagoons are one of the most economical and efficient systems of biological treatment of residual liquids, by the low energy and maintenance costs, joined to the simple operation and high efficiency in the abatement of pathogenic bacteria and parasitic eggs.

The quality of the effluent is determined by natural conditions that need to be predicted and quantified efficiently.

The purpose of this research is to determine the kinetic constants of fecal contamination indicator bacteria as an indirect measure of the presence of pathogenic bacteria and to obtain a correlation model of air - liquid temperatures that will allow estimating the effluent temperatures in the lagoon and thus predict the efficiency of bacteriological and organic load removal from the treatment system for regional conditions.

This research aims to contribute to the analytical formulation of effluent treatment by stabilization Lagoons and optimize its calculation.
