Specifics Water Treatment Manganese Removal Degremont174;
Oxidation using oxygen only reaches an appreciable rate when the pH rises above 9.5 (figure 31). Mn 2+ oxidation using oxygen depends on temperature: oxidation will be 5 times faster when the temperature rises from 11 C to 22 C; however, at normal pH levels, contact times are not easily compatible with industrial operation.. The presence of manganese dioxide catalyses the reaction.
