different pH’s to optimize the process. In theory, the reactor
B2 is for aluminum precipitation and B3 is for manganese
precipitation. Figures 15 and 16 show the two configura-
tions tested. Configuration B had the best performance
because it required less sludge that needed to be recycled,
giving better control to avoid aluminum re-dissolution that
could occur during the sludge recycling process.
