Dissolved manganese has become prevalent in many drinking water systems and is causing aesthetically displeasing issues for consumers. The goal of this project was to elucidate the mechanisms of manganese sequestration using a polyphosphate and suggest an efficient method toward producing water that will not form manganese precipitation. Experiments completed included polyphosphate and ozone dose variations at varying pHs and detention times. The results that were obtained showed that sodium triphosphate effectively sequestred manganese and reduced the presence of precipitate.
