Abstract
This thesis investigates the potential for iron and manganese removal with a calcium carbonate fluidized pellet bed reactor. The East Brookings Water Treatment Plant ground water supply in Brookings, South Dakota was the source water used for optimization of the fluidized pellet bed reactor pilot plant for iron and manganese removal. The pilot plant consisted of a raw water supply that was treated with an aerator, fluidized pellet reactor and a filter. The scope of the research was to determine optimal operating conditions for iron and manganese removals along with calcium carbonate removal. Within the fluidized pellet bed reactor, optimization was examined by varying the pH between 8.5 and 10.0, varying the unfluidized sand/pellet height in the reactor, varying filter types and changing the pH raising solution between caustic soda, simulated lime and lime. The results indicated the optimum pH for the pellet reactor was at pH 9.5. The optimum pH raising solution was determined to be caustic soda. There was no significant difference between the changes in the bed height. Two different filter types were used in the experiments, 0.45 μm filters and a granular media filter. The 0.45 μm filters were more capable of removing iron while the granular media filter was more suitable for the removal of manganese.
