Abstract
A floc foam flotation pilot plant was shown to remove lead and zinc in dilute aqueous solution to quite low concentrations. The results suggest several design improvements. These include: (1) a larger mixer-flocculation tank to increase the detention time of the floc before flotation; (2) increased baffling of the stripping column section, to decrease channelling and foam overturn at high loadings; and (3) a decrease in the length of the foam drainage section of the column, to decrease the tendency of the foam to collapse before dishcarge....The flotation of Fe(OH)3 flocs with NLS is impeded by several polyvalent anions, some of which occur in inudstrial cleaners. These anions displace surfactant from the floc, rendering it unfloatable. This phenomenon, an interference in waste treatment, could be used to relcaim surfactant from flotation sludges. A surface adsorption model for floc foam floatation was anlayzed and found to account for the effects of surfactant concentration, ionic strength, specifically adsorbed ions, and surfactant hydrocarbon chain length.
