Descrição: The removal of various colloids (humic acid, silica, polystyrene latex, and bacteria) by microflotation in the presence of aluminum salts has been studied as a function of pH. The conditions for efficient separation have been correlated to the stability of these colloids, and it was shown that in all cases rapid flotation occurred when the aluminum salt concentration and the pH adjustment rendered the sols unstable. Particularly high removals were observed over the pH range of aluminum hydroxide floc formation. Microflotation could be utilized as a nonspecific method for simultaneous removal of mixtures of colloidal pollutants.
