Inhibition of Mn(II) Oxidation Performance in the Presence of High  Residual Mn(II) Concentrations
This study explores the influence of residual Mn(II) on the biological Mn(II) oxidation performance in reactor systems, employing two identical reactors operating at varying Mn(II) loading rates. The results unequivocally reveal that high concentrations of residual Mn(II) exert a substantial inhibitory effect on Mn(II) oxidation activity. This inhibition can be attributed to the diminished tolerance of specific Mn-oxidizing bacteria to elevated Mn(II) levels.
