c] values: 1,000; 1,500 and 2,000 during the electrodissolution stage and its effect on the flocculation stage.
Figure 6 shows the behavior of the residual turbidity and lime consumption in the range of pH tested for flocculation.
The following equations show the possible reactions of different ions in the solution during the flocculation process.
Figure 8 shows the characteristic porosity of the settled solids obtained during flocculation, this would have relation with phenomena of aggregation of amorphous species of ferrous-hydroxide and of slaked lime colloidal.
By coupling iron electrodissolution and chemical flocculation processes, a reduction of 84% of total solids content, 54% of chemical oxygen demand, 88% of dissolved carbon content and 76% of color were achieved in raw vinasse with low power consumption (0.
