Abstract
La invencion se refiere a un método biologico para el tratamiento de aguas negras, en el cual primero se pasa gas a través de una mezcla de lodo y aguas en una etapa de activacion, y después el lodo activado se separa por flotacion de las aguas negras tratadas; el método se caracteriza porque la concentracion de lodo en la etapa de activacion es >- o g/l y porque la flotacion se logra por medio de la liberacion de presion.
