PROCESSO E INSTALACAO PARA A SEPARACAO DE ESMALTE E AGUA

摘要

A method for purifying polluted water by adding compressed air and intimately mixing it by circulation in a first operating stage so as to form a foamy mixture, then allowing the foam to float to the surface of the water and removing the foam and thereby partly cleaning the water, then subjecting the partly clean water to a second operating stage in which compressed air is again added to the water and the mixture is again thoroughly circulated and intimately mixed to produce a foam, and the foam is again allowed to float to the surface of the water, and then removing all of the foam from the cleaned water.
