Descriptor espesamiento por flotación
Scope note: Proceso para aumentar el contenido de sólidos de lodo y, en consecuencia, reducir su volumen. En la densificación por flotación, se introduce aire en la solución a través de una cámara de alta presión. Cuando la solución se despresuriza, el aire disuelto forma microburbujas que se dirigen hacia arriba, arrastrando con ellas las escamas de lodo que se eliminan en la superficie.
