Abstract

Procedimiento y aparato para el tratamiento de agua residual, incluyendo el procedimiento una etapa en la cual se separa un gas de un líquido, caracterizándose el procedimiento porque comprende reducir la presión sobre la superficie del agua residual, durante la etapa de separación de gas, a un valor inferior a la presión atmosférica, en un grado suficiente para causar la liberación de una proporción de cualquier gas disuelto o burbuja presente en el agua residual.Process and apparatus for the treatment of residual water, the process including a stage in which a gas is separated from a liquid, the process being characterized in that it comprises reducing the pressure on the surface of the residual water, during the gas separation stage, to a value below atmospheric pressure, to a degree sufficient to cause the release of a proportion of any dissolved gas or bubble present in the wastewater.
